CyberGrid is committed to energy transition in SEE with its aggregation solutions

Project Manager and Market Intelligence Specialist Nikolaj Candellari from CyberGrid said at the Belgrade Energy Forum 2025 that the company believes in the energy transition in Southeastern Europe and is contributing with its VPP solutions. The Austrian software developer is open to partnerships with aggregators or future aggregators and the region’s electricity transmission and distribution system operators.

CyberGrid connects different energy resources to different markets. It uses cloud-based flexibility management technology and provides software as a service (SaaS).

“Our core belief is that every energy resource should be renewable, or at least green, and flexible. And to support this transition which we are in at the moment, we have developed our own product called CyberNoc,” Project Manager and Market Intelligence Specialist Nikolaj Candellari said at Belgrade Energy Forum (BEF 2025).

[wpcc-iframe title=”Nikolaj Candellari, Project Manager and Market Intelligence, CyberGrid at Belgrade Energy Forum 2025″ width=”500″ height=”281″ src=”https://www.youtube.com/embed/T_Oy574YR9k?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

CyberNoc in real time aggregates the assets – batteries, renewables and even loads and is putting them to the markets, Candellari explained.  In this way, the company supports grid stability and resilience and generates additional revenue streams for owners.

“We are heavily present in the region because we believe in this transition in Southeastern Europe. We helped partners in Croatia, Bulgaria and North Macedonia to connect to different markets,” he stressed and added that the firm has established cooperation in Slovenia and Greece.

Candellari called on aggregators or future aggregators, transition and distribution system operators and all other entities in the electricity system to contact CyberGrid.

The company, founded in 2010 and headquartered in Vienna, is one of the friends of the Belgrade Energy Forum, organized in Serbia’s capital city by Balkan Green Energy News.

CyberNoc enables trading, balancing services

CyberNoc manages battery storage, power plants and consumption, optimizing them in line with market and grid conditions. The platform continuously communicates with the transmission system operator (TSO). It facilitates energy trading as well as the provision of balancing services including frequency control reserve (FCR), automatic frequency restoration reserve (aFRR) and manual frequency restoration reserve (mFRR).

Candellari also participated in a panel discussion at BEF 2025 called Market Flexibility: The Backbone of a Resilient Energy System. He recalled that the market went from 15-minute time intervals all the way down to just two seconds and stressed the significance of real-time data for TSOs and other participants.

“I think we can connect everything, including households,” Candellari underscored.

Notably, CyberGrid is part of the SPRINT project, launched at the beginning of the year, for the development of innovative quasi-solid-state sodium-ion batteries for stationary purposes. The endeavor received funding through the Horizon Europe program.

ACER’s Zinglersen: Integrate electricity markets to bolster flexibility as new era is already here

The surge in the number of hours with negative wholesale electricity prices in Europe made 2024 the second consecutive record year. According to ACER’s Director Christian Zinglersen, it means a new era is here. Speaking at Belgrade Energy Forum – BEF 2025, he called on governments, regulators and system operators to tackle the issue with more flexibility and reap the benefits of integrated electricity markets.

At EUR 81 per MWh, the average day-ahead power price in the European Union and Norway was lower last year than in 2021, when the energy crisis began. This is good news, but there are significant differences in price averages across the continent, Director of the EU Agency for the Cooperation of Energy Regulators (ACER) Christian Zinglersen asserted.

In a keynote speech at Belgrade Energy Forum, BEF 2025, he also pointed out that the percentage of days with significant price swings remained elevated. “This suggests that we need much more short-term flexibility in the system,” Zinglersen said.

[wpcc-iframe title=”Belgrade Energy Forum 2025 Christian Zinglersen, Director, ACER” width=”500″ height=”281″ src=”https://www.youtube.com/embed/c2JGLvLEInQ?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

Prices in Romania, Bulgaria, Greece, Hungary among highest in Europe

In 2024, the share of time when prices were above EUR 150 per MWh landed at 6.1%, compared to 11.3% in the previous year and 66.7% in 2022. The number of days with price swings greater than EUR 50 per MWh accounted for a strong 70.4% of the total, though down from 77.1% in 2023 and 87.8% one year before.

The average price in Romania was virtually unchanged in 2024. It fell only 1% in Bulgaria and 5% in Hungary. Conversely, the drop was the strongest in Sweden, Norway, France and Belgium: 22% to 39%.

The average day-ahead electricity price in Romania was virtually unchanged last year, while in several countries it tumbled by at least 22%

Last year, prices were the highest across Italy, between EUR 106 per MWh and EUR 112 MWh, in Ireland (EUR 109 per MWh), Romania (EUR 104 per MWh), Bulgaria (EUR 103 per MWh) and Greece and Hungary (both EUR 101 per MWh).

Importantly, 2024 was the second consecutive record year in the number of hours with negative wholesale prices. Their share jumped to 2.8% from 1.9%.

“This is very significant and it shows we are already, in my view, in a new era. We’re not just embarking upon it. We’re there,” Zinglersen stressed.

Share of very low wholesale prices rallies back to level from 2020

As for the share of time with very low wholesale prices, it surged last year to 8.8%. The level was last seen in 2020, when the pandemic erupted and resulted in an unprecedented demand shock, ACER’s chief noted. He called on governments, regulators and system operators to tackle the issues with more flexibility.

Grid tariffs increasingly need to show what the system needs, in his view: more time nuance and more locational nuance. “That combination of an energy signal and a tariff signal should hopefully enable us to build more of what we need in the right places, as opposed to build what we don’t need, in the wrong places,” Zinglersen stated.

Integrated markets bring benefits

A policy brief that Brussels-based think tank Bruegel published last year pointed to the benefits of the integration of electricity markets. Among other factors, there is more security with fewer backup power plants and more flexibility with less investment in energy storage, together with lower capital costs. In 2022, ACER, based in Ljubljana, estimated benefits from cross-border trade alone at EUR 34 billion in the EU.

“It has very significant security of supply implications as well, to be in a very integrated-type jurisdiction,” Zinglersen underscored. But integrated markets come with tradeoffs, he said.

One of the examples is an incident in 2021 that split the Continental Europe synchronous area into two parts for an hour and reserves were pulled from across the continent. “But you can also bring the system much more quickly back together again,” Zinglersen said at the conference.

The same goes for the June 2024 blackout in the Balkans.

There are many solutions in Europe, but they are not evenly distributed

ACER’s director also recalled the power price decorrelation that affected Southeastern Europe and Hungary from July to September. He attributed some of the spikes in day-ahead prices to the lack of short-term flexibility, for instance batteries.

There are lots of technical solutions and frameworks in place across Europe, but they are not very evenly distributed, he added.

Zinglersen pointed to the opportunities and benefits of further integrating the electricity market of the Western Balkans region and the EU.

NGEN showcases solutions at BEF 2025 for decentralized electricity grid of tomorrow

Slovenia-based NGEN, widely regarded as the most innovative energy company in the SEE region, is expanding throughout Europe with its software platforms and equipment, as well as battery energy storage systems for decentralized grids that enable scaling up the decarbonization of the electricity sector. Co-Founder and CEO Roman Bernard said at the Belgrade Energy Forum 2025 that the company is establishing a digital endpoint for every network element. It enables real-time control over production and consumption, preventing blackouts and providing cybersecurity. At the conference, NGEN presented its services for the construction and operation of BESS and access to all segments of the electricity market.

In NGEN’s vision, the electricity system becomes fully digital and decentralized, with every house and business taking an active part in it.

Grid congestion is becoming more frequent, limiting the current rapid deployment of renewables. Most of Europe has centralized networks, where energy flows in one direction, from large power plants to consumers. Grid balancing is still conducted on a 15-minute basis, which is too slow for real-time demand.

NGEN has created platforms for energy that is produced, stored and consumed locally. It is developing a more efficient and reliable environment that can keep up with the scaling up of renewable energy technologies.

NGEN has answers for all challenges of power system

The Slovenia-based company is tackling all current challenges that the power system is facing, Co-founder and Chief Executive Officer Roman Bernard said at Belgrade Energy Forum – BEF 2025. NGEN, the technology sponsor of this year’s conference, operates in nine European countries.

[wpcc-iframe title=”Roman Bernard, Co founder & CEO, Ngen at the Belgrade Energy Forum 2025″ width=”500″ height=”281″ src=”https://www.youtube.com/embed/BchbVdSzoMo?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

Pointing to the pace of increase in solar and wind power plant capacity over the past years, Bernard said a centralized system wouldn’t be able to support the overall production and consumption anymore. “We want to make a digital endpoint for every unit that is included in the network. Through it we can communicate and raise or decrease consumption or production,” he explained.

Bernard: Cybersecurity is the most important part of digitalization

It enables control over the system, as otherwise it is in risk of blackouts, while such a transformation also brings significant savings in infrastructure, according to Bernard. He also stressed cybersecurity as the most important part of digitalization.

The CEO of NGEN, which stands for next generation, added that the sector needs to be further regulated across Europe to facilitate the construction of a new kind of infrastructure, as well as to motivate the corporate sector to get involved.

The company’s representatives Marco Scholz and Patrick Simon held a presentation at BEF 2025

Instant frequency response preventing cascading blackouts

In Bernard’s view, now is the time for battery energy storage systems (BESS), after a massive renewables capacity was added to the system in the last seven or eight years. The CEO was one of the panelists at BEF 2025 in a session on flexibility services called Market Flexibility: The Backbone of a Resilient Energy System.

NGEN developed its own software as well as hardware for running decentralized systems, cybersecurity and access to all segments of the energy market. The software has never gone down so far, its representatives said during their presentation at the conference. The firm is a contractor for engineering, procurement and construction (EPC) of BESS, also providing maintenance and operation.

[wpcc-iframe title=”BEF 2025, Grid Intelligence for energy security how NGEN Synaptic prevents systmatic blackouts” width=”500″ height=”281″ src=”https://www.youtube.com/embed/kcm6UtVTcpA?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

Its intelligent software ESGP, Energy Smart Grid Platform, provides instant frequency response preventing cascading blackouts. NGEN’s digital platform, called SG Connect, reacts automatically, providing backup in the event of a failure in under 20 milliseconds, enabling real-time grid balancing. At the same time, it monitors and manages in two-second intervals, through the NGEN Synaptic artificial intelligence (AI controller).

It is a plug-and-play module, installed at energy assets, connecting them to ESGP, the transmission system operator (TSO) and all relevant markets, the company said. On the customer side is the SG Connect application.

NGEN has projects of 2 GWh in Europe under development or in construction. As for notable operational facilities, it installed a BESS in Kidričevo in Slovenia, with 35 MW in operating power and 70 MWh in capacity. The facility is about to get an extension of 70 MW – 140 MWh.

BEF 2025: Digitalization, open markets, time are major preconditions for flexibility services mainstreaming

Digitalization and massive use of data are crucial for providing flexibility services that bring benefits for transmission system operators and renewable energy producers. Aggregators and software firms have developed the technological solutions. However, the process, together with the introduction of flexibility platforms, requires a long time. The reforms also have to be accompanied by market liberalization and end consumers acting as active buyers, according to the participants of Belgrade Energy Forum 2025.

The panel on flexibility services called Market Flexibility: The Backbone of a Resilient Energy System was one of eight that were held at Belgrade Energy Forum 2025 (BEF 2025).

The conference, organized by Balkan Green Energy News, welcomed four hundred participants from more than 30 countries from the region, Europe, and beyond.

“Flexibility has been promoted in Europe as a buzzword, sometimes reflected as demand-side flexibility, but it represents so much more. It includes supply-side flexible assets like hydro, biomass, storage, as well as grid-side flexibility,” according to panel moderator Elena Boškov Kovacs, co-founder and CEO of Blueprint Energy Solutions, and a leading voice on market flexibility in Europe.

Serbia will introduce a flexibility services market

Serbia’s transmission system operator (TSO) Elektromreža Srbije (EMS) is preparing to liberalize the ancillary services market. The country adopted the Law on Energy in November and implemented a large proportion of the European Union’s Electricity Integration Package (EIP) while the remaining parts will be transposed through bylaws.

“The balancing capacity market will be liberalized from next year. We will have new participants – active buyers and independent aggregators,” said Marko Zarić, Head of the Market Operations sector of EMS.

He stressed that the TSO is trying to ensure that no market participant is impaired by engaging flexibility resources or demand side response or a balancing service.

“EMS has finished drafting the new market code, which envisages dual balancing responsibility. We will launch a public debate on the act. The TSO estimates that it is the best solution to open the market of flexibility services,” he noted.

Bernard: Technology is on our side

NGEN CEO Roman Bernard expressed the opinion that the region is moving in the right direction, and suggested to regulators to look around and implement best practices. If the participants in the market are motivated, things will go forward, he added.

Back in 2019-2020, when NGEN started its operations in Slovenia, flexibility services were a pioneering job. The Slovenian energy company, the technology sponsor of the BEF 2025 conference, specializes in premium battery energy storage systems (BESS) and smart energy solutions.

According to Bernard, the balancing services market in the EU is well developed thanks to balancing platforms MARI (Manually Activated Reserves Initiative) and PICASSO (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation).

“We have 150 employees, and we can do everything. Technology is on our side and the sky’s the limit,” he stressed.

For example, NGEN solutions can provide monetization of battery energy storage systems (BESS), and the only thing that is needed is investors in such facilities.

Digitalization is the only way forward

The representatives of aggregators KOER and Alteo and software company CyberGrid all agreed that digitalization and the use of data are crucial for the energy transition.

Compared to NGEN and its use of BESS, Croatia-based KOER, a pioneer in virtual power plants in the region, is utilizing existing assets, like diesel generators, or employing the flexibility intrinsic to most manufacturing companies; for example, cement factories and wood manufacturers.

Existing assets work well, not just batteries, KOER COO Luka Renko stressed.

The only problem, in his words, is digitalization. The majority of the said firms aren’t ready to connect to the platform to be automatically switched on and off. The markets are getting faster and faster, so digitalization is the only way forward, Renko claimed.

Alteo, a leading Hungarian aggregator, also believes in lots and lots of data, which back up its scheduling and contribute to the security of supply.

Tokai: Alteo is looking for partners in the region

“Our superpower is providing scheduling services with the support of AI, including lots of data,” said Magdolna Tokai, Deputy CEO for International Relations and Corporate Services of Alteo.

Hungary has experienced a photovoltaic boom in the past four or five years, with the installation of almost 8,000 MW. It’s good for greening power production, but not from the perspective of a TSO, and that is where aggregators come into the picture, she added.

Alteo is combining conventional resources like gas-fired power plants with renewables. It currently has 140 MW in renewable resources, it manages 2,000 MW of third-party solar, and operates two virtual power plants. The company is providing the service to small photovoltaic facilities and the TSO.

Alteo is integrating solar energy in a product that is close to baseload, and placing it on the market. It translates to lower balancing costs for solar and a more stable product for the TSO, she explained.

Serbia is facing a challenge from the upcoming 1.2 GW of solar power

Alteo has just started implementing its new strategy for regional growth by exporting know-how on balancing services and providing flexibility to market players.

According to Nikolaj Candellari, Project Manager and Market Intelligence of CyberGrid, real-time data gives a TSO and other market participants the possibility to understand where they are.

He recalled that, over the years, the market went from 15-minute time stamps, down to one minute, and that now it is only two seconds. The improvement helps dealing with challenges, and CyberGrid knows a lot about such issues.

“For Serbia, the challenge comes with 1.2 GW of solar, which will be installed next year. So if you don’t see it as a challenge, ask yourself who needs 1.2 GW of energy at noon on Sunday,” Nikolaj said.

Over its 15 years of existence, CyberGrid developed good examples of how to exchange data with assets and TSOs.

“Assets are always the same, no matter the country, but to have this data exchange with TSOs, or even market platforms, that is something I think we need to do in the future in Southeastern Europe,” he stressed.

How to get to the future: properly liberalize markets

Elena Boškov Kovač (Blueprint Energy Solutions) asked the panel participants what the solution is for addressing different types of flexibility assets including prosumers.

“How do we avoid getting stuck in the easy-to-commercialize part of the aggregation, and postpone the true demand response, which is needed to avoid the issues with negative pricing and electricity market swings?” she asked.

There is no dilemma for Nikolaj Candellari (CyberGrid): “I think we can connect everything, including households.”

It is something futuristic, he said. “We have to try to go as low as possible and connect everybody because, in the end, it’s not different if you have a 1 MW battery or 100 smaller residential ones” of 1 MW combined, Candellari asserted.

His company is currently implementing a project to integrate 150 batteries of 2 MW overall and put them on the market.

The batteries can drive the prices for end users down by 25% within five years

Candellari and Roman Bernard (NGEN) alike highlighted the factor of market motivation.

Bernard said motivation is created by the market. The imbalance price can go up to EUR 15,000 per MWh, and it is the signal and the motivation to fix everything, in his opinion.

He is convinced that batteries can lower the prices for end users by 25% within five years if dynamic prices are applied.

According to Nikolaj Candellari, participants will come to the market, as long as it’s not too regulated. As an example of a non-functional market, he mentioned Bulgaria, where the capacity price for downward regulation is zero.

“So, why would anybody join the market, if the capacity price is zero? Get the market running and you will get participants and capacity needed to balance it,” he said.

Tokai: We need a proper energy mix

Magdolna Tokai (Alteo) has a slightly different view of the markets. She recalled that episodes of negative prices are happening in Hungary, while that last August and September very high prices were recorded on HUPX, up to EUR 1,000 per MWh, and above EUR 500 per MWh in Croatia and Serbia.

“We have to be prepared for that, which is data, data, data, and the cooperation of all the market players, providing the proper energy mix, and the proper product for the TSO,” she pointed out.

Marko Zarić (EMS) stressed time as a vital ingredient for developing markets. A transition from the regulated market to the truly open market envisages multiple steps that take time, he said.

Flexibility platforms need time for implementation

Another big change are the balancing platforms developed by aggregators. Traditionally, TSOs were buying the same kind of standardized product, for example, SCADA, EMS, and other market applications, with more or less the same kind of functionalities.

Elena Boškov Kovač (Blueprint Energy Solutions) brought up the question of a more standardized approach. “Before we start talking about interoperability and connecting with everything else, would it be good to at least have platforms with similar kinds of functionalities and services provided?” she asked.

According to Luka Renko (KOER), every platform is structured in line with the needs of the operator. The communication platforms are more or less standardized, but it depends on what one needs in the background and what kind of assets they drive.

Piloting a flexibility platform can take years

The two aggregators, KOER and Alteo, developed their platforms because they couldn’t find a ready-made solution on the market.

A platform must have the ability to communicate with any other solution and to integrate new types of power plants and customers, Magdolna Tokai (Alteo) added.

Elena Boškov Kovač (Blueprint Energy Solutions) recalled that her company has implemented flexibility platforms since 2019, at the dawn of the opening of the flexibility market in Europe, and added that pilot projects for them take a long time.

“They require an immense amount of data. There’s a multitude of different stakeholders that need to support this, unlock the data, provide data resources. Piloting is incredibly important, and it can take years,” she pointed out.

Luka Renko (KOER) added that it took his company three to four years to start working as an aggregator in Croatia.

The future is bright, but we need to work on it

The panelists with Branislava Jovičić, Founder and Editor of Balkan Green Energy News (photo: Balkan Green Energy News)

Summarized, here are the messages of the session’s participants:

Bernard (NGEN): The end consumer will start acting as an active buyer.

Zarić (EMS): We see changes in the future.

Candellari (CyberGrid): Open the markets.

Tokai (Alteo): Give a chance to all market participants and types of production.

Renko (KOER): Digitalization will help.

Elena Boškov Kovač (Blueprint Energy Solutions) praised the companies that had their representatives at the panel for starting to develop solutions ahead of the market reform.

“It’s also a good message to the system of sometimes sleepy energy companies waiting for their proprietary vendors to offer them solutions,” Boškov Kovač stated.

Decarbonization of Southeastern European region: both renewables and nuclear are speeding up

Energy transition in Southeastern Europe is accelerating, and the progress depends on individual countries’ strategies and legal frameworks. At the Belgrade Energy Forum (BEF 2025), representatives of state-owned power utilities and private producers discussed the different approaches to decarbonization. The domination of investments in renewable energy is unquestionable, but there are also ambitions to develop nuclear capacities, spearheaded by Slovenia. The country is already operating one nuclear reactor and is developing a project for another one.

The electricity sector in Southeast Europe still depends for a large part on thermal power plants that burn fossil fuels. In 2023, they accounted for 43% of overall output, of which two-thirds were from lignite and the rest from gas. There is a need for accelerated decarbonization, and the speed of the transition will depend on financial possibilities and the political will and decisions, said the panel’s moderator and Director of Zagreb-based Energy Institute Hrvoje Požar Dražen Jakšić.

The acceleration trend in decarbonization is also evident in the electricity market projections for the region until 2030. The plans for the period until the end of the decade include shutting down 6.2 GW of thermal power plant capacity and installing 42.3 GW from renewable sources. Greece, Romania, Serbia and Bulgaria are expected to add the most.

Top executives of state-owned utilities in Serbia, Slovenia and Montenegro and independent power producers that invest in renewables in the region gathered at a panel called Decarbonisation strategies for power generation in Southeast Europe 2040/2050 at Belgrade Energy Forum 2025.

They agreed that decarbonization is well underway and an unstoppable process already speeding up significantly. The participants in the discussion presented the different strategies their companies will act upon in the following years and decades, leading the process to fulfilment.

Among the messages that they shared is that they expect each government to promote investments and make the legal framework clear and certain, while the countries strengthen their ties and exchange experiences. Green energy is the pillar of the energy transition and decarbonization in the region, but several states are also interested in building their first nuclear power plants—conventional ones or small modular reactors (SMRs)—or expanding the existing capacity.

EPS’s Živković: Decarbonization requires energy storage, nuclear plants

Chief Executive Officer of Serbia’s Elektroprivreda Srbije (EPS) Dušan Živković pointed out that the state-controlled electricity producer is committed to its goals regarding green energy and emission reductions as well as to the country’s targets. “We will work on that, of course, believing in these objectives, but without compromising energy security and the energy sovereignty of Serbia. It was proven to be the only sustainable path,” he asserted.

The company particularly counts on the project for solar power plants with a total connection capacity of 1 GW, with batteries of 200 MW in combined capability. The investment is conducted through a strategic partnership with Hyundai Engineering and UGT Renewables (UGTR).

A study is underway in Serbia on the potential for the construction of large nuclear power plants and small modular reactors

The decarbonization process won’t be easily feasible without serious energy storage capacity, Živković warned and added that nuclear energy wouldn’t be unrealistic. A study is underway on the possibilities of building large nuclear plants and small modular reactors in Serbia.

The head of EPS expressed the belief that “the quality of that energy needs to be visualized” for citizens of every country and that they should be explained that it is necessary to provide energy for the economy and its security.

No dilemma in Serbia about energy transition

Country Manager of WV-International in Serbia Neda Lazendić highlighted the said strategic partnership for solar power plants with battery energy storage systems (BESS), saying Hyundai Engineering is a world-renowned company.

In her view, the endeavor will be a milestone for the entire region and it is exceptionally important for gaining experience at the domestic level.

The recent second round of auctions for electricity from renewable sources showed that Serbia opted for the energy transition “and there is not any dilemma about it anymore,” Lazendić stressed and said the country is an example for the region. The prices from the bidding that were accepted are appealing and they match European trends, she noted.

Lignite is highly unprofitable

Slovenia and GEN energija, one of the state-owned power utilities, are relying on both renewable sources and nuclear energy in their decarbonization investments, the company’s CEO Dejan Paravan pointed out.

“We want to get rid of coal as soon as possible. And in the short term, renewables are the only option. Why get rid of coal? The current production of domestic lignite is highly unprofitable, and because of climate goals,” he explained.

Nevertheless, it is exceptionally complicated to get permits for renewables and place them in the environment, Paravan added. On the other hand, nuclear energy is emissions-free and very stable and reliable, he asserted. The technology takes up the least space and enables the production of huge amounts of electricity, the head of GEN energija said.

Nuclear power plant Krško 2 could come online in 2040

Paravan recalled that two years ago nuclear power plant Krško marked four decades since it was commissioned and that its operating life was extended by 20 years. GEN energija is working on the Krško 2 project. The chief executive expects construction to begin in 2022 or 2023 and that the reactor could be connected to the grid in 2040.

In parallel, the company is studying SMRs. Still, the development of the technology will take a long time and, importantly, such facilities won’t have the advantage of scale like large reactors, he said. One who expects electricity from SMRs to be cheaper than from big nuclear plants is wrong, in Paravan’s view.

As for the dilemma between renewable sources and nuclear energy, he expressed the belief that they are not mutually exclusive. “We need renewables and they can provide us a lot of CO2-free electricity in the short run. But let’s make it clear that once we come to 70%, 80%, 90% based on renewables, that we have a problem of seasonal storage, that things will get very difficult,” Paravan stated.

Batteries are ten times cheaper than ten years ago

Conversely, Akuo Energy’s CEO Eric Scotto pointed out that nuclear power is expensive. “It’s over. We won the race. Renewable is the cheapest way to produce energy,” he underscored.

The price of energy storage capacity is ten times lower than ten years ago, the head of the French company noted. Moreover, operating power of a battery system in a standard TEU container, twenty feet or 6.1 meters long, now reaches 6 MW, which is three times more than three years ago, according to Scotto.

To attract investments, stability is necessary, he stressed. Scotto went on to highlight some “simple things” that could help Akuo, which was one of the winners at the last auction round in Serbia, to materialize its projects for two wind parks. He mentioned the speed of permitting for telecommunication systems and road construction, for power plants.

Turning to the slowness of the energy transition in Balkan countries, he emphasized its positive side. “We are late. Then we will benefit from the cheapest resource, the cheapest way to produce energy,” Scotto concluded.

EPCG’s Solari project kicked off energy transition in Montenegro

Technical Director of Elektroprivreda Crne Gore (EPCG) Ljubiša Đurković called the state-owned power utility’s projects Solari 3000+ and Solari 500+ the start of the energy transition in Montenegro. Since the beginning of 2023 and including Solari 5000+, launched later, the company set up photovoltaic systems on 7,380 structures, he revealed.

Total peak capacity reached 76 MW and another 125 MW will be installed by the end of the year, EPCG’s official said.

Among its projects, the company is building the Gvozd wind farm, and the Kapino polje solar park near Nikšić.

Technical Director of EPCG Ljubiša Đurković

There is already 10 MW on roofs in the former Željezara steel plant in Nikšić, and before the end of the year another 15.5 MW will be connected to the grid, Đurković said. A contract has been signed for the construction of the eighth generator in the Perućica hydropower plant, of 58 MW. It is scheduled for completion in 2027.

Đurković: A realistic date for the closure of the Pljevlja thermal power plant is between 2045 and 2050

The energy transition is about a single and connected system, including storage capacities and measures to improve energy efficiency, he underscored. “You have to create the conditions for a swift integration of renewable energy sources into the distribution and transmission networks. We were supposed to do that already. We didn’t do it, particularly in the Western Balkans. We didn’t reconstruct the distribution and transmission networks,” he stated.

As for the current reconstruction of the coal-fired Pljevlja thermal power plant, the only one in Montenegro, Đurković said the project wouldn’t make sense if the facility were to keep operating only for a short while longer.

žAccording to the National Energy and Climate Plan (NECP), which is almost complete, it will remain active at least until 2041, although the realistic date for its closure is only between 2045 and 2050, in the opinion of EPCG’s technical director. The main phase of the reconstruction began at the end of March.

Clock is ticking for introducing carbon tax in Western Balkans, many ambiguities still remain

From January 1st, 2026, Carbon Border Adjustment Mechanism (CBAM) will be effective in the Western Balkans. While the countries are still deciding on the carbon pricing model, the energy intensive industry is advocating for introducing taxation to protect the domestic market from the flood of goods that will not be competitive on the EU market. Even though the Governments might not have been proactive enough in the previous years, the participants of the CBAM panel on BEF 2025 believe there is still time for the regional actors to come up with more proactive approach towards the EU.

Energy Community Contracting Parties are approaching critical choices on carbon pricing that will shape the pathway towards climate neutrality, electricity market integration and sustainable economic development. From January 1, 2026, producers of aluminum, fertilizers, cement, steel, and hydrogen, as well as electricity exporters, will be required to pay the tax on CO2 emissions released during the production of the goods they export to the EU.

At the Ministerial Council in December 2024, four carbon pricing models were presented to the Contracting parties: regional emissions trading system (ETS), national carbon taxes, fixed-price Emissions Trading System (ETS), and full integration with the EU ETS. Upon the request of the Contracting parties, the Energy Community Secretariat provided an impact assessment for all four scenarios. The scenarios differ in structure and scope, but all support a common goal: progressive alignment with the EU ETS and the implementation of the polluter-pays principle.

The Ministerial Council is expected to meet in July to reflect on these scenarios and decide on the preferred regional pathway. This decision will shape the revision of the Decarbonisation Roadmap and guide the implementation of carbon pricing reform up to 2030 and beyond.

Carbon pricing is also central to the region’s electricity market future. The Electricity Integration Package, adopted in 2022, outlines the path to full market coupling between the Energy Community and the EU. To avoid distortions and ensure a level playing field, timely carbon pricing implementation is essential. “The projections shows that if the region would join EU ETS after 2030, the carbon price should reach or even exceed 100 euros per ton of CO2. This would have serious consequences for energy prices, competitiveness and industrial exports. Also, delaying actions could prove to be costly. That’s why contracting parties are expecting to implement domestic ETS for electricity with the price equivalent to EU ETS”, Milica Brkić Vukovljak, from Energy Agency of the Republic of Serbia, explained.

The expectations around the CBAM introduction in the region were the main topic of discussion on the BEF 2025 panel Addressing carbon pricing in the Western Balkans – Turning decarbonization challenges into opportunities through collaboration, innovation and competitiveness, moderated by Brkić Vukovljak.

The key message from the panel is that regional governments need to take a more active role, especially towards the European Union, and numerous arguments were put forward during the discussion in that direction.

As for Serbia, it is worth noting that it is the only Contracting party of the Energy Community that had transposed the Electricity Integration Package, through which transit of importance for traders takes place. Given that the market coupling is scheduled for the beginning of 2027, it would be important to try to get the European Commission to postpone the deadline from 2026 to 2027.

Introduction of CBAM should not interfere with market integration

While admitting that „it’s never a good moment politically to decide on carbon pricing“, Adam Cwetsch, Head of the European Green Deal in the Energy Community Secretariat, said he believed that the current momentum in the region, together with cumulated experiences, could allow making such a decision at this time.

He recalled that the decision on carbon pricing was partially left open with the 2021 Decarbonization Roadmap. At the same time, the Green Agenda for Western Balkans is referring to alignment with the EU ETS, as an objective that countries should aim.

„The role of Secretariat is to facilitate making those decisions, fully informed. It entails certain risks, but it is also helping the countries in their journey to join the EU eventually. Another important consideration is setting standards for monitoring emissions, which the countries are obliged to establish and make as of 2026. This is necessary for any credible carbon pricing system, regardless of the chosen model, as they all require credible data and standards“, Cwetsch said.

He insisted that the market integration and market coupling should not be disturbed with the introduction of CBAM, making it a priority to synchronize the situation within the region.

Any model to be decided has to have, as an end point, alignment with the EU ETS

“The least desirable solution would be that there is a country that progresses faster than others and is forced to implement an internal Energy Community CBAM”, Cwetsch said, advocating for a coordinated approach towards setting up the carbon emissions price.

He also noted that any model to be decided must have, as an end point, alignment with the EU ETS. „That should be taken into account when designing the pathway with selected option“, he added.

As things now stand from January 2026 CBAM will be effective, while the market coupling, that allows for exemptions, will not be yet in place. „It is important not to end up with disintegrating the market“, Cwetsch noted.

On the other hand, he believes there is a space for more proactive policy from the Western Balkans actors. „The region should reach out to the EU with more proactive climate policies, which would make clear how the region could contribute to the 2030 or 2040 targets for climate neutrality that EU is striving“, he concluded.

Without carbon pricing mechanisms, the regional markets will be flooded with imports

The representatives of energy intensive industry are concerned that past discussions about carbon pricing didn’t pay enough attention to the interests of the companies that are going to be directly affected by imposing tariffs on exports to the EU.

Branko Zečević, president of the Metalfer Group and one of the founders of the Association of Serbian Energy Intensive Industry, said that the introduction of CBAM from the beginning of next year will certainly affect Serbian exports, even though many companies have been preparing for this moment and investing in decarbonization. „Some companies are further down that road, some are at the beginning, and the effects can’t be quantified easily right now“, he argued.

Once you have saved the industry, you have somebody to tax. Otherways, there will be nothing to talk about

However, Zečević insisted that much bigger threat for industry in Serbia and the region, is the expected flood of goods that will not be able to enter EU market anymore and will try to find third markets.

„Markets in the region are pretty opened for that sort of import. An imperative is therefore to have our own carbon pricing system, however you may call it. We must protect our market from these consequences, otherways we will not have any industry to protect in the future“, he insisted.

In his opinion, the first step should be to copy-paste what the EU is doing, to protect the industry, and after that we can talk about the models of carbon pricing. „Once you have saved the industry, you have somebody to tax. Otherways, there will be nothing to talk about“, he warned.

Asked about the expectations of the industry from the Government, he said that financial assistance does not seem a realistic option in the Western Balkans, but there are regulatory measures that could help the companies.

„Industry is more complex than coupling the electricity market, as every industry is different. The companies in the EU received billions of euros in grants over the last 15 years, while the companies in the region were left on their own, each individual company, to make its own adjustments. What the governments in the region can do is to put in place regulatory rules to help and protect local industry and then as a next stage to see if it can implement that regionally“, he concluded.

CBAM ambiguities rising concerns for energy traders

The ambiguities that follow the introduction of the emissions trading mechanism in the region are more likely to deter than to attract energy traders. Mark Copley, CEO of Energy Traders Europe, association representing 170 energy traders, some of them being active in the region, noted that there is confusion and concern regarding the implementation of CBAM in Western Balkans.

“Lots of questions have been raised: how is that going to work, how the price of CO2 is going to be calculated, what does this means for market integration, how the traders will actually be able to transit power through this region etc”, he said.

Energy traders are pretty good with price risks and volume risks, what we fear is political risk and regulatory risk

While noting that traders generally think that carbon pricing is a good idea, he warned that a good idea in principle could have significant unintended consequences in practice. Energy traders are pretty good with price risks and volume risks, what we fear is political risk and regulatory risk. „I’d like to think that this moment is an opportunity to sit down with all the parties involved to try to sort out the rules”, Copley said.

Copley insisted that he doesn’t have a specific view on what form of pricing is right from the region, but reminded of the experience when Great Britain created its own ETS, which proved to be more volatile, risky and difficult to operate.

„The bigger, more stable, more integrated market – the better. When you have ETS as a large and liquid system, it is fairly easy to trade and manage risks. However, it gets more difficult where you don’t know what the policies are in the short term or in the long term. While I understand the desire that the model should reflect the specifics of the market, be careful in small markets with not much liquidity, because it is hard to design good systems for them”, Copley noted.

Carbon pricing models should reflect the interests of each country in the region

The regional non-governmental organizations also have been raising their voice over the topic of CBAM in previous years. One of the warnings of possible negative economic and social impacts was the analysis Chaotic and fake decarbonization of power sectors in the Western Balkansin 2023.

The problem is that the introduction of CBAM in often seen as a kind of natural disaster, something inevitable that is about to happen”, said Damir Miljević, member of the Board of Center for Sustainable Energy Transition, RESET, a think-tank that published the report mentioned.

In his opinion, Western Balkan countries did not participate actively in the process with lobbying and negotiating with the EU. „The policy makers sit in Brussels, while the Energy Community Secretariat is the directorate for the implementation of the international agreement. I don’t recall that some delegation from the Western Balkans went to talk to the EU about exemptions, even though we had at least one strong argument. Stabilization and Association Agreement with the EU states that neither contracting party will introduce additional taxes, or levies on the other, which means that even if they are introduced, we would have to negotiate about it“, Miljević explained.

The advantage should be given to the model that is fastest and simplest to implement, which is direct taxation

Another argument for negotiations is even stronger – the countries that are candidates for EU accession should not have the same treatment as some very distant states on other continents, he argued. Miljević also added that the region should focus on transferring the acquis from the EU, which they are obliged to, not the policies, where the situation is completely different.

„In the present situation, the only viable solution is to introduce some form of taxation of CO2 for the industry“, he said. In his opinion, this means the advantage should be given to the model that is fastest and simplest to implement, which is direct taxation, to eliminate the influence of CBAM on the export of industrial products from the region to the EU.

„It would be difficult to consider regional schemes, due to huge differences within the region. We already lost too much time on it. Each country should do it individually considering its own interest, not the interest of the energy sector, but the interest of the citizens and the economy and the consequences for them. This way, we will get some initial, however small assets, to start solving the core issue. We should also remember that the introduction of levies on CO2 is essential for the creation of any fund for coal regions in transition”, Miljević concluded.

Battery storage market in SEE emerging, Western Balkans lagging behind with positive prospects

The deployment of battery energy storage systems (BESS) across Southeast Europe is progressing at an uneven pace. State subsidies and financing mechanisms have enabled the rapid implementation of BESS solutions in Greece, Romania and Bulgaria, while markets in the Western Balkans are lagging behind. However, the outlook remains positive, as experiences from neighboring markets and best practices from other parts of the European Union can help overcome initial challenges and streamline the deployment process. This was highlighted by participants of the panel dedicated to BESS at the Belgrade Energy Forum.

Among the technologies required for the energy transition, battery energy storage systems (BESS) stand out as a key factor for integrating electricity from intermittent renewable sources – wind and solar power – into the grid. There are few such facilities in Southeastern Europe and the segment is yet to even be fully regulated in the narrower Western Balkans region. The panelists at a session called Energy storage system market in SEE: trends and forecasts, at Belgrade Energy Forum (BEF 2025), outlined the trends in the budding market.

There are more and more cases of low and negative hourly prices in the wholesale electricity market in the region, providing a clear business case for BESS investments. In addition, the grid is often overloaded on weekends and holidays when solar and wind power production is high, given the weak demand.

Managing Director of Go2Power Consulting Goran Vukojević, who moderated the discussion, warned that negative prices may jeopardize system stability as well, if operators of power plants disconnect them from the grid at the same time, to avoid costs.

He highlighted the preparations in Serbia’s transmission system operator Elektromreža Srbije (EMS) for auctions for ancillary services and praised the company for transparency in regulating the competitive process. The other option for battery operators is to participate in the open market.

Region seen with 9 GW of BESS operating power in 2030

Ioanna Barouni from Aurora Energy Research said a total of 40 GW of solar and wind power is expected to be online at the end of 2025 in the SEE region, comprising 12 countries, including Hungary. In 2030, the level is expected to reach 70 GW, which is expected to be doubled to 145 GW by mid-century. As for BESS, projections stand at 9 GW in 2030 and 25 GW in 2050.

Barouni: We miss flexibility and ancillary services for transmission and distribution system operators

The countries of the region are retiring power plants that use fossil fuels, a firm capacity, in Barouni’s words, while adding renewables. “It’s not very easy to predict how the generation profile is going to be during the day, so we miss flexibility and we miss ancillary services for TSOs and DSOs,” she said.

The gap between power prices for midday and the evening is gradually increasing. Barouni explained that batteries “create some artificial demand and absorb these low prices.” At peak demand and with less renewables, a battery can replace expensive fossil fuels, lowering the price.

Serbia preparing auctions for ancillary services

Division Manager of transmission system operator (TSO) EMS Nikola Tošić acknowledged that Serbia is preparing auctions for ancillary services. He revealed that there would probably be one auction for 70% of the needed reserve in the first year. The next rounds would be more frequent, shifting toward daily auctions for balancing capacity.

In the verification process, EMS’s System Operation Department will first test the battery, Tošić added. State-owned power utility Elektroprivreda Srbije (EPS) already provides ancillary services to the TSO, so it won’t require tests, he asserted.

Serbian law defines ancillary services the same as European Union does

EMS drafted the new grid code, and it will publish the draft balancing market code for public discussion soon, according to Tošić. He said the domestic law defines ancillary services in the same way as the EU defines them in its legislation. One part is balancing services: frequency containment reserve (FCR, primary), automatic frequency restoration reserve (aFRR, secondary) and manual frequency restoration reserve (mFRR, tertiary). The other part are non-frequency services – energy.

“We think that it would be good to incentivize the periods of the year or periods of day when the needed amount of reserve is more attractive or more in demand,” Tošić said.

Fortis Energy moving ahead with battery investments regardless of government support schemes

Fortis Energy’s Chief Executive Officer for Eastern Europe Nikola Oklobdžija considers the lack of regulation to be the biggest challenge for developers. An investor can currently only focus on charging the batteries when the prices are low and sell when they are high, he underscored.

The Turkey-based company develops photovoltaic, wind power and BESS projects in the region. The first bigger investments in renewable electricity plants with energy storage are the ones that will break the ice, in Oklobdžija’s opinion.

“Of course, it helps if you have a CfD contract, so the banks will look at it more favorably,” he stated. Oklobdžija added that companies need to be able to present revenue to the lenders and what the fees are for renting the capacity or providing different services.

Bankability depends on state support and PPA contracts, cash flow models and insurance

In the meantime, Fortis is examining the experiences in Bulgaria and Greece, which have already held auctions for standalone batteries. Financing a project is easier with a CfD – contract for difference, but the company is determined to push ahead anyway, Oklobdžija stressed.

In North Macedonia it commissioned a solar power plant in Oslomej and recently contracted a BESS to be added to the facility. Oklobdžija said it wasn’t a requirement but that Fortis opted for energy storage because of market pressure with prices and occasional curtailments, like during Easter last month.

The introduction of ancillary services would facilitate the development for standalone battery systems, he explained.

Cerović: First there will be more projects for colocated BESS units than for standalone facilities

Head of Specialized Lending at UniCredit Bank Serbia Svetlana Cerović highlighted the intensive activity in Germany and Italy, for instance, but also in neighboring Romania. UniCredit is present in those markets and is analyzing the development of the battery storage market, she pointed out, arguing that the best practices in the EU are the best way for building and financing battery storage.

Cerović said there would first be more projects in the region for BESS colocated with renewable energy plants than standalone units.

She suggested that the proposed investments that include storage should be better pondered at the next renewable energy auction in Serbia. It is in the country’s interest to enable providing flexibility and to support the projects, she said.

There may be a rationale for subsidizing prosumers to add storage in Serbia, Cerović said. Turning to small-scale projects, she expressed the belief that power purchase agreements (PPAs) are “convenient” for them. She is recommending dedicating a certain capacity for the category at the next auction in the country.

The first projects in Serbia, conditioned by energy storage requirements for a grid connection, are in the process of negotiating financing, according to Cerović.

Fire protection is especially significant for insurers

Renewable Energy Insurance Broker (REIB) has insured some 4 GWh of energy storage capacity in Bulgaria and just as much elsewhere in the world, Business Development Manager Dimitar Dimitrov said. Developers should contact insurance companies when the design is done, as well as for cargo insurance, he suggested and added it is particularly important for projects that get subsidies.

“We’re not only insurance brokers, but we’re also investors, which helps us understand a bit more about the clients’ needs, and what we can definitely do more in cases of coverage. Understanding clients’ needs helps us also prevent risks that could occur during certain stages,” Dimitrov stated.

Most insurers prefer at least a six-meter distance between containers or rows of three to four containers holding batteries, he said. It is the most important factor in fire protection, in Dimitrov’s opinion. When the distance is shorter than three meters, a firewall is required for insurance, he explained.

The next segment is construction insurance. For insurance companies, it is not a higher risk profile, Dimitrov asserted. Next, he recommended operational risk insurance including coverage for business disruption, and insurance against cyberattacks. In such events, the grid connection can be damaged, the company’s representative pointed out. “Insurance policies are definitely bankable,” he added.

Bulgaria has completed its tenders for state support to BESS combined with renewable energy plants, and for standalone units. But even before subsidies, batteries have been delivered and facilities are under construction, Dimitrov stressed. Many photovoltaic projects in Bulgaria have emerged in the past few months and most of them include BESS, he said.

BEF 2025: Corporates’ education, product diversification crucial to speed-up PPA uptake

Capacity building and education for corporates, together with product diversification and an upgrade of the regulatory framework, could clear the obstacles for power purchase agreements in the Western Balkans, which are lagging behind the other countries in Southeast Europe. In addition to their other benefits, such contracts could contribute to securing baseload energy from hybrid facilities, given that baseload is a key issue for the decarbonization of the region, according to the participants of a panel on power purchase agreements, held at Belgrade Energy Forum 2025 (BEF 2025).

BEF 2025 has gathered four hundred participants from more than 30 countries in the region, Europe, and beyond.

The panel PPAs as a key to renewable energy growth in SEE featured stakeholders from all segments of the PPA market: developers, corporates, utilities and consultants. The discussion comprised five segments – the global trends, main drivers, the region’s specifics, challenges and trends, and the implications of the model.

The panel’s moderator was Mislav Slade-Šilović, Energy, Utilities & Resources Consulting Leader for Southeast Europe and member of the core PPA team at the consultancy PwC.

Global trends: PPAs are hot, but the solar capture rate is becoming an issue

Mislav Slade-Šilović, Joffroy Beckers and Nikola Gazdov

According to Natalija Ljubić, Manager of PPA & BESS Transactions at Pexapark, PPAs are still hot in Europe. On a monthly basis, between 500 MW and 2,000 MW of new PPAs are signed (15 to 30 deals). She referred to long-term, fixed-price PPAs considered bankable and publicly announced. There is much more together with short-term PPAs, for two to three years.

There is an impression that everything comes down to corporate PPAs, but there are many utility PPAs that aren’t always made public, she added.

The majority are physical PPAs but Pexapark is registering more and more financial PPAs. In 2025, almost 20% of all the announced PPAs were financial, whereas a couple of years ago, they made up 5% to 10%. There are more pay-as-produced contracts than the monthly ones for baseload energy.

Mislav Slade-Šilović (PwC) added that 70% of PPAs in SEE are virtual or financial.

It’s quite challenging in the region to find a creditworthy counterparty on the consumer side

For developer Joffroy Beckers, Head of PPA at DRI, it’s quite challenging to find a creditworthy counterparty on the consumer side of the market in the region comprising Greece, Bulgaria and Romania. So when the firm wants to speed things up with selling its electricity, it goes to utilities or traders.

Negative prices are emerging in the region, with much more cannibalization for solar in the long term, he added.

According to Bulgaria’s Association for Production, Storage, and Trading of Electricity – APSTE, the situation in the region is different than five years ago. “There were zero PPAs in the region, but now they start to get common. Paradoxically, the conditions start getting much more and more complex,” chairman Nikola Gazdov said.

Mislav Slade-Šilović (PwC) pointed to the decline in the solar capture rate – the ratio of the price of solar power and wholesale price. It is spilling over to the PPA price and increasing its complexity, and solar PPAs are generally more complex than the ones for wind power, he added.

Main drivers: Different priorities ask for different PPA models

Natalija Ljubić, Ivana Đurović and Davor Pupovac

For Ivana Đurović, Category Manager Renewable Energy at Knauf Group, PPAs are a game changer in energy procurement because essentially it’s no longer just about buying energy or hedging. “Now corporate PPAs bring the long-term deal, so they even extend the tenure for those hedging, and they also allow us to achieve our sustainability targets,” she explained.

PPAs aren’t for companies with consumption below 30 GWh or 40 GWh per year, while branding and cost savings are often the reasons for companies to sign them.

Such factors determine the PPA product that the offtaker opts for, Mislav Slade-Šilović (PwC) stressed.

According to Nikola Gazdov (APSTE), in the region comprising Bulgaria, Romania, and Greece, PPAs are usually signed by corporates that have some ESG commitments or want to show their clients and customers that they are thinking green.

The key feature of a PPA is the partnership between two companies

As examples of the various kinds of deals, he mentioned a physical PPA with an electricity-intensive consumer, virtual PPA with a telecom and a PPA with a big international company producing tires, combining the two types.

As a developer, DRI is modifying its strategy toward a mixed portfolio. Instead offering a solar asset for a PPA, it adds wind power plants and combines different technologies into a single contract. “It allows us to capture a better price, and this is also usually more beneficial for the off-taker. The second thing is that we’re trying to keep this upside in our PPA by entering a floor price instead of a fixed price,” Joffroy Beckers (DRI) revealed.

For Mislav Slade-Šilović (PwC) the key characteristic of a PPA is the partnership between two companies. It needs to be balanced, to ensure that both parties can fulfill throughout the tenure. If one goes bankrupt, then it doesn’t make sense for both parties, he underlined.

The specifics in the region: Corporates need to learn, PPAs should be more diverse

Nikola Gazdov, Natalija Ljubić and Ivana Đurović

Serbia’s state-owned power utility Elektroprivreda Srbije (EPS) has been signing a lot of PPAs. However, the difference from the conventional deals is that they are based on premiums. But according to Davor Pupovac, head of the company’s market analysis and risk management, it is interested in corporate PPAs that don’t include government support. There is not much interest among consumers for corporate PPAs with EPS, he revealed.

Mislav Slade-Šilović (PwC) said the role of EPS and big power utilities is very important in developing the PPA market. A dominant supplier in a market has a critical role, either as a sleever or as someone that will provide B2B products to off-takers and developers or producers for entering the market, he said.

Joffroy Beckers (DRI) agreed with him about the role of big utilities in facilitating PPAs and expressed the belief that in the near future, they would get a larger share as intermediaries.

Asked if corporate PPAs are coming anytime soon in Serbia, Davor Pupovac (EPS) said: “Not so soon.” However, he claimed EPS wouldn’t lose consumers regardless of the fact that it has no such product.

Corporates aren’t super ready for PPAs because they are seeking stability when it comes to the energy price

In Ivana Đurović’s (Knauf) view, there are several reasons for the slow uptake of corporate PPAs in the Western Balkans. Corporate buyers aren’t super ready for PPAs because they are seeking stability when it comes to the energy price, but the pay-as-produced PPA model is dominant in the market, which doesn’t ensure price stability. Monthly baseload deals would enable more price stability.

A bigger offtake through PPAs requires corporates to build their capacity for closing such deals and for the offer to be more diverse, she stressed.

Natalija Ljubić (Pexapark) agreed with her and suggested that companies need to understand more about the risks and accounting. Also, not many corporates are willing to enter five- to ten-year agreements as they don’t know their demand or costs that far ahead, Ljubić underlined.

Challenges, risks: Management boards are delving into energy-related topics in detail

Ivana Đurović and Davor Pupovac

Creditworthiness is one of the key challenges, Joffroy Beckers (DRI) said. As he sees it, credit insurance could be key, providing a kind of a state guarantee. Nikola Gazdov (APSTE) again stressed education. He also recalled that all European countries needed time to get along with PPAs.

“But coming to credit risk, I think that now we also see the European Commission taking note of the situation,” Gazdov noted.

As for education, Mislav Slade-Šilović (PwC) said it requires one to two years. Management boards of companies from different industries on the offtake side are forced to delve into energy-related topics in detail, he noted.

There are practically no obstacles for PPAs in Serbia

Slade-Šilović asked EPS’s representative whether the utility is prepared to offer B2B products, arguing that they go hand-in-hand with PPA market development.

Davor Pupovac (EPS) responded that there are practically no obstacles to PPAs in Serbia. Namely, there is an electricity exchange, EPS is willing to sign contracts with developers for sleeving or balancing, the guarantees of origin (GO) system is in place, and EPS is active on power exchanges in the region as a producer and supplier.

“EPS could also offer a route to market to the off-taker. However, currently, it cannot offer access to the spot or forward market,” he explained.

Coming from a corporate electricity consumer, Ivana Đurović (Knauf) was curious what EPS could offer to a perfect corporate off-taker asking for a physical PPA. Pupovac answered that currently it would be a pay-as-produced deal.

What does the implementation bring us: hybrid combinations open the room for innovative deals

Joffroy Beckers, Nikola Gazdov and Natalija Ljubić

Mislav-Slade Šilović (PwC) summarized the landscape. “If you look at the broader EU situation and challenges, especially with solar capture rates, negative prices, we are now already discussing technology advanced structures including batteries and other hybrid solutions on the PPA side,” he underlined.

Natalija Ljubić (Pexapark) pointed out that last month in Germany the solar capture rate was just 40%, calling it almost unbearable for photovoltaic projects. All developers or energy producers, especially in the solar power sphere, are seriously considering adding batteries, while projects for standalone battery storage facilities are appearing, in her words.

She and Nikola Gazdov (APSTE) agreed that the outcome is a lot of interesting innovative structures, room for different solutions.

BESS with solar reduces cannibalization and increases capture rates

Ljubić said it is a challenge to maximize revenues from a battery system and make it bankable. Gazdov pointed to the dilemmas of a single company owning different assets versus a big utility combining and aggregating everything, and whether the producers or optimizers manage the revenue streams.

When it comes to standalone storage units, he sees a perspective only in arbitrage and, perhaps, system services further down the road.

Joffroy Beckers (DRI) explained the main purpose of a battery energy storage system (BESS) in Romania, from the point of view of a developer and power producer. A BESS combined with solar power reduces cannibalization and increases capture rate, whereas wind lowers the balancing cost, he stressed.

“If you co-locate a battery next to solar, you will be in a position to negotiate a higher price on the off-take side,” he pointed out.

A combination of wind, solar and batteries is equivalent to a new power plant

In the future, he anticipates more PPAs with a pay-as-nominated structure rather than pay as produced, arguing that it enables more flexibility for monetizing batteries on different markets.

“With those combinations of wind, solar, and battery, basically you have a new power plant, baseload structure,” Mislav Slade-Šilović (PwC) stated.

That way PPAs fit into the broader discussion on the energy transition and decarbonization. EPS is decarbonizing its production through its role as a renewable energy offtaker.

“Hybrid combinations are partly addressing the baseload needs. So, many different technologies, including storage, can provide a part of the answer this region heavily needs, and this is the baseload substitution problem,” Slade-Šilović concluded.

BEF 2025: Technologies for energy transition are here, getting cheaper every day

Technologies for the energy transition already exist, and their use is increasing thanks to falling costs. Investors and bankers claim they are ready to invest and that money isn’t an issue. The missing part are upgraded transmission grids, along with policies and regulations to integrate everything into a suitable environment, according to investors and lenders gathered at Belgrade Energy Forum 2025.

The third Belgrade Energy Forum, BEF 2025, welcomed four hundred participants from more than 30 countries from the region, Europe, and beyond. The two-day conference was organized by Balkan Green Energy News.

Participants in the panel Energy revolution underway – uniting efforts to deliver green, intelligent, and sustainable energy solutions were Maja Turković, Senior Vice President of CWP Europe, Aleš Prešern, Vice President and Head of Southeast Europe of Siemens Energy, and Christian Beynio, Head of Advisory of Kommunalkredit Austria AG.

According to panel moderator Mirza Kušljugić, a member of the Board of the Regional Center for Sustainable Energy Transition (RESET) from Bosnia and Herzegovina, the energy transition is actually a revolution, given the technological changes.

“The region is still burdened by tradition. We know the transition is inevitable, but we aren’t fully aware that it will be disruptive,” Kušljugić stated.

Technology is here, and so is financing

Maja Turković, Senior Vice President of CWP Europe, stressed that technology, currently undergoing a revolution, is the best card the world has in the transition. She even suggested that financing isn’t a problem and that there are more financial resources available than projects qualified to receive funding.

However, she is surprised by the rapid growth in solar power installations. Turković argued that market-based projects cannot achieve double-digit internal rates of return on equity. Part of the explanation may lie in the fact that panel prices have dropped by 60% over two years.

Battery prices have also fallen. The largest drop was last year, 40%, with a further 5% decline this year alone, according to Turković. Prices have slipped below EUR 100,000 per MWh.

Turković: Regarding CAPEX and technology, we’re ready

The latest trend is the integration of batteries with solar power plants. While transmission system operators in the region still don’t allow it, in some countries a grid connection approved for solar can also be used for batteries. “Regarding CAPEX and technology, we’re ready,” Turković underlined.

Aleš Prešern, Vice President and Head of Southeast Europe in Siemens Energy, is particularly impressed with the speed of change.

“We who are working in the energy sector are used to very slow changes. Energy was a conservative industry. In 2004, 1 GW of solar was built, but now data shows that it is how much is installed in one day. Batteries cost EUR 1 million per MWh not that long ago, and now they are ten times cheaper,” he noted.

Prešern: Transmission networks are the bottleneck of the transition

They are indeed dramatic changes, for which the existing power system wasn’t prepared. It is clear why Siemens Energy, as a technology company, considers transmission networks to be the bottleneck in the transition, Prešern said.

To illustrate the slowness of grid investments, he pointed to Austria, as one of the examples, where it took 10 years to build one important segment of the 400 kV network.

Both Turković and Prešern agree that nowadays the keyword is flexibility.

She explained there are operating battery management systems at low voltage levels that incorporate artificial intelligence and use market signals for activation when prices are low.

Prešern added that the required stability through balancing could be provided by gas power plants. Siemens Energy has never seen such high demand for gas turbines like today, he asserted.

Beynio: Don’t forget the non-banking institutions when looking in new financing

“If you ask about availability of financing, yes, it’s there,” Christian Beynio, Head of Advisory at Kommunalkredit Austria AG, confirmed. In his view, prices or, rather, the drop in prices of equipment, is the biggest innovation. Earlier, he said, it was a completely different game, heavily subsidized, while nowadays no subsidies are required per se.

The trend that Kommunalkredit Austria AG identified is the pooling of smaller assets, and a shift from financing projects toward financing developers and companies as corporates. It is yet to come to the region, he added.

Investment in grids, in his words, has to be initiated by the government. They have two solutions – go to the sovereign debt market or engage private investors. “Don’t forget the non-banking institutions when looking for new financing. This is a trend across Europe, and it will be relevant for the Balkans,” Beynio advised.

Battery projects won’t go so smoothly

Maja Turković expressed the belief that installing batteries won’t go as smoothly as solar. The main reason is the difficulty of securing a stable cash flow for batteries, unlike for production facilities. Cash flow enables financing, so batteries will likely need to be financed with internal funds, she underlined.

Turković noted that batteries are best monetized by providing system services and arbitrage, but pointed out they can also participate in capacity mechanisms, a scheme that could involve power purchase agreements (PPAs).

She said the development of the regulatory framework should be faster, to facilitate investments in batteries. Investors are ready to commit their funds to battery installation, and everyone in the market agrees that batteries are essential, Turković stressed.

Prešern: People and not technology are a guarantee that networks will exist and function properly

Amid the widespread discussions about technology and regulations, Aleš Prešern highlighted another issue. Energy, in his opinion, has always been an exciting sector, but the message hasn’t been getting through to young people in recent years. It was the case not only in the region but also in Europe, and beyond, leading to a shortage of skilled personnel.

However, he expressed the belief that things are changing and enthusiasm is returning. Prešern even suggested it could be a major advantage for the region, well known for its high-quality engineers.

Siemens Energy strives to employ as many good engineers as possible because, ultimately, people and not technology are a guarantee that networks will exist and function properly, he stressed.

The solution is also in using new technologies to better utilize existing grids

The combination of rapid changes in the energy sector and slow investments in the grids threatens to put the transition to a standstill.

Better utilization of existing infrastructure could be the solution. Siemens Energy fits well there, as several years ago it established a division called Digital Grid. According to Prešern, the idea was to be quicker in data utilization, something that other sectors like automotive have long advanced, while energy has lagged.

The company recently acquired a Slovenian-Austrian firm that produces sensors installed directly on power lines, a technology called dynamic line rating. The devices provide real-time data about the conditions in power lines, potentially enabling their use beyond original design limits.

“With this technology, we believe we can increase the capacity of existing networks by an average of 30%,” Prešern revealed.

New technologies have changed bankers’ jobs as well

New technologies have changed bankers’ jobs as well, Christian Beynio admitted. He recalled that it was easy to finance wind farms in Serbia because they had feed-in tariffs from the government. The only risk element was the wind blowing or not blowing, Beynio said.

Nowadays there are merchant power producers that combine their facilities with batteries and use algorithms in electricity trading, he added. It means bankers need to sit with market consultants to identify all outcomes, he stressed.

“You won’t find singular cash flow streams. It’s going to be multi-dimensional and people simply need to adjust. It’s going to be more short term also on the lending side. It’s rather going to be corporate lending to people and companies who know what they are doing and can credibly demonstrate that with a track record. That is the digitalization impact we see”, Beynio said.

BEF 2025: Regional cooperation can facilitate energy transition, energy security

Montenegro, Serbia, and the Republic of Srpska don’t have a problem attracting investments in electricity production, but they do have issues when it comes to investments in transmission networks. If the introduction of CBAM is not postponed, it will greatly burden their economies. Hungary is interested in strengthening energy ties with them as well as the rest of the Western Balkans, which would bolster energy security for the whole region. Croatia could also assist it in strengthening employment in the green technologies sector, to counter the loss of jobs due to decarbonization. These are the main messages from the High-ministerial panel on SEE regional cooperation and energy transition strategies.

The ministerial panel was the first of eight at this year’s Belgrade Energy Forum 2025 (BEF 2025). The conference, organized by Balkan Green Energy News, welcomed four hundred participants from more than 30 countries from the region, Europe, and beyond.

The panel featured representatives of the governments of Montenegro, Croatia, Hungary, the Republic of Srpska – one of the two political entities in Bosnia and Herzegovina – Serbia, and the United Nations Economic Commission for Europe (UNECE). The moderator of the panel was Dirk Buschle, who until recently was a key figure in the Energy Community Secretariat, and now is a partner at law firm Becker Büttner Held.

He noted it is a mistake to say that the contracting parties of the Energy Community are lagging behind EU countries in the energy transition. They all face the same issues, which are energy accessibility, supply security, and sustainability, Buschle added.

Additional proof, in his words, are the similar issues faced by investors – in grid connections and permitting.

Investments in production are coming, the issues are grids, CBAM

Dirk Buschle, Petar Đokić and Admir Šahmanović

According to Minister of Energy and Mining of the Republic of Srpska Petar Đokić, the entity has made significant progress in defining a regulatory framework that aligns with the rules of the Energy Community and the European Union.

He noted that with the help of the Energy Community Secretariat, the two entities of BiH recently reached an agreement on adopting a law on the electricity regulator, transmission, and market. It is one of the cornerstones for establishing an organized electricity market.

The Republic of Srpska was successful in attracting investments in green energy in recent years, Đokić added. It established concessions and partnerships for the construction of 2,200 MW of renewable energy power plants – wind, solar, and hydropower.

However, large investments in transmission networks are also necessary, he pointed out and said he expects assistance from the European Union’s financial institutions such as the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB), as well as the World Bank.

Đokić: CBAM to hit hard BiH’s economy

The minister called on them to set up such partnerships.

Regarding the EU’s Carbon Border Adjustment Mechanism (CBAM), he said that measures have been taken to change the domestic energy mix. Until recently, the share of fossil fuels was 62%, but it has now dropped to 54%, he recalled.

By 2028, the Republic of Srpska will have two new hydropower plants, of 159 MW and 36 MW, and new solar power plants with a total capacity of 250 MW, the minister asserted. It would additionally green the energy mix, Đokić said.

CBAM, in his words, could harm the economy of the Republic of Srpska and BiH.

If it is applied the way it is apparently envisaged, it would result in a significant increase in costs, with a severe negative impact, he underlined. Đoković expressed hope that the rollout would be separately discussed in the case of BiH.

Šahmanović: Montenegro is finishing its NECP

Montenegro also enjoys great interest from investors. It has received applications for building solar power plants and wind farms with a total capacity of 5.5 GW, said Admir Šahmanović, Minister of Energy and Mining.

The country’s current capacity is slightly over 1 GW.

It is, in his words, the result of improving the regulatory framework including the adoption of laws on renewable energy sources and energy. However, investment in the transmission grid is also necessary. The government plans to discuss with Italy the possibility of installing another subsea cable for electricity transmission, while the national energy and climate plan (NECP) will be completed by the end of next month, the minister revealed.

Montenegro is requesting a postponement of CBAM until 2030

In addition, renewable energy auctions are being prepared with the EBRD, and a memorandum on market coupling with Italy will be signed, he added.

As for CBAM, the minister stressed that Montenegro doesn’t believe the EU wants to harm its economy, but argued that the country isn’t ready for the mechanism’s implementation.

“Perhaps we are now in a situation similar to where our EU partners were 20 years ago. So, we need to invest a lot in our production capacities, grid, storage. It will take years, so if we don’t receive an exemption by 2030, I believe we won’t be able to handle this challenge,” Šahmanović stressed.

Secure supply of the national market is the highest priority

Boglárka Illés, Admir Šahmanović and Jovana Joksimović

Jovana Joksimović, Serbian assistant minister of mining and energy for international cooperation, European integration, and project management, expressed the opinion that the energy transition is a long and intensive process, technically, operationally, and financially.

Since October 2022, renewable energy in the energy mix has increased by 83%, which demonstrates the progress of the energy transition in Serbia, Joksimović asserted.

“We need to be realistic, as well as socially aware, because a fair and sustainable transition is something that should be carefully considered when changing the energy mix, where coal accounts for 60%,” she noted.

Joksimović: The priority is to ensure a sufficient supply of electricity at the most affordable prices for citizens and the economy

It is necessary, in her words, to be ambitious and dedicated to the energy transition goals, but she is convinced that there is a higher objective.

At the country level, it is to ensure enough electricity at the most affordable prices for both citizens and the economy, she underlined. “That’s what our top priority is,” Joksimović underscored.

Guided by the said goal, Serbia is also considering the use of nuclear energy and a study on possible options is currently being prepared.

Boglárka Illés, State Secretary for Bilateral Relations at Hungary’s Ministry of Foreign Affairs and Trade, also stressed that the government’s primary duty is to ensure not only climate neutrality and sustainable energy but also affordable energy with a stable supply for households and businesses.

She pointed out that diversifying energy imports and the energy mix plays a key role in securing energy sovereignty. It is the reason why cooperation with the Western Balkans, and especially Serbia, is important to Hungary, Illés asserted.

Illés: Europe’s energy security has been demolished

A few days before, Hungary’s Prime Minister Viktor Orbán said the EU has abandoned a successful economic strategy, based on cheap Russian gas and advanced German technology.

“And now we don’t see any other strategy within the EU,” she stated.

Due to ideologically driven sanctions against Russia, and the European Green Deal, the energy security of Europe is demolished, in Illés’s opinion. The region is located at the intersection of essential energy routes, connecting the East and the West, and also South and North, she underlined.

“We, as an EU member country, can act as a bridge between non-EU member countries and also the EU,” the state secretary stressed.

As an example of good cooperation with Serbia, she highlighted the supply of gas through the TurkStream pipeline and the Pannonian Corridor project for doubling the capacity for power exchange between the two countries.

The energy transition is an opportunity

Jovana Joksimović, Marija Pujo Tadić and Dario Liguti

In one respect, Marija Pujo Tadić, Special Envoy for Climate Action from the Government of Croatia, doesn’t share the opinion of the Hungarian official. She argued it isn’t true that Europe lacks a plan.

The EU has a clear plan and a well-defined strategy – it is the Clean Industrial Deal, she stressed.

She highlighted two important strategies relevant to the region: the Paris Agreement and the Green Agenda for the Western Balkans.

As a member of the scientific advisory board for the COP 29 presidency, she recalled that this year a review of nationally determined contributions (NDCs) would be conducted. It is an assessment of how countries are meeting their plans for lowering CO2 emissions.

Pujo Tadić: Education and workforce specialization are essential

She underlined the Green Agenda for the Western Balkans also envisages reducing net greenhouse gas emissions to zero by 2050, which is essentially the shared goal of the EU.

However, Pujo Tadić expressed the belief that policies and laws alone are not enough. Public education and workforce specialization are also necessary because the transition will create many new jobs, she added.

Croatia could be of great support to the Western Balkans, having launched such educational programs five years ago, according to Pujo Tadić.

The link between the energy transition and the creation of new jobs was also stressed by Dario Liguti, Director of Sustainable Energy at UNECE. In his view, the region has a huge opportunity to become part of the supply chains for green technologies by greening the domestic power generation and by leaning on the EU’s energy transition.

He sees the main factors for it in the region’s geographic proximity to the large European market, and the large, skilled workforce that can be educated for other tasks. Liguti drew a connection with the expected job loss from decarbonization measures and the related need for a just transition.

Liguti: There is great potential for energy efficiency in the region

Liguti praised the forthcoming investments in renewable energy production, but warned it is only one side of the story, arguing that the other one is energy efficiency. He reminded the audience that the region’s energy intensity is high, saying there is room for savings.

The installation of big solar plants and wind farms, in his words, is great because it’s very visible.

“It’s a great investment and makes a lot of sense. The harder part is making energy efficiency investments, whether in buildings or the industrial processes in large, small, or medium enterprises,” Liguti stated.

As an example, he recalled that UNECE is running a project with the EBRD in North Macedonia to support households and small and medium enterprises to lower the costs of liquid fuels and electricity.
