Alteo’s Chikán: Aggregators have AI solutions for grid stability, production optimization (video)

Factors like power price volatility, the global shift in policy making and the need for flexible solutions for the integration of renewables are creating an important momentum for developers and aggregators, Chief Executive Officer of Alteo, Attila Chikán, said at Belgrade Energy Forum 2025. The company is expanding in Central and Southeastern Europe with investments in power plants and its AI-backed platform for operating third-party assets.

The electricity system needs to become more and more flexible to accommodate weather-dependent, intermittent sources – solar, wind and hydropower, Alteo’s CEO and Chairman of the Board Attila Chikán said and pointed out that the outage in Spain and Portugal on April 28 highlighted the need for investing in grid stability and upgrades.

In his keynote speech at Belgrade Energy Forum (BEF 2025), he stressed that a global shift in policy making in the sector, particularly in the United States and Europe, is bringing both challenges and opportunities. In Chikán’s view, the situation creates an important momentum for developers and aggregators.

[wpcc-iframe title=”Belgrade Energy Forum 2025 – Attila Chikan Jr., CEO and President of the Board, ALTEO Plc” width=”500″ height=”281″ src=”https://www.youtube.com/embed/FZCrhx8yh6E?feature=oembed” frameborder=”0″ allow=”accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share” referrerpolicy=”strict-origin-when-cross-origin” allowfullscreen=””]

“In the past five years we have seen a great deal of price volatility on the markets in the region. If you look into the future, taking into account the impact of the ambitious plans of regional countries to expand renewable power, one might expect even more pressure on balancing price volatility,” he asserted.

Role of international initiatives

Alteo’s CEO said tailored incentive mechanisms are essential for developing a balanced energy mix. There are also major endeavors on an international scale, Chikán added: connecting markets with diverse geographical characteristics, power plant portfolios and different supply-demand balances.

He explained that cross-border initiatives such as PICASSO and the Blue Sky project bring electricity exchanges in the region closer together. Interconnectors like the Pannonian Corridor and the proposed Black Sea green cable contribute to balancing and the management of energy price volatility, Chikán noted.

Future-proof tech solutions required for risk mitigation

In risk mitigation, the energy system’s stability benefits from future-proof technological solutions as well, namely smart metering, advanced weather forecasting and artificial intelligence–based production optimization, he said. This is where aggregator companies like Alteo come into the picture, its chief underscored.

As for its hardware, the company based in Budapest operates a diverse and balanced production portfolio of gas power plants and renewables, combined with storage, Chikán added.

Alteo runs a portfolio of gas power plants, renewables and storage facilities

“Sounds good, but without a well-designed and functional software, any hardware is purely a collection of materials. And even if they do operate, for sure they operate in a suboptimal way, without synchronization,” he stated.

That’s why Alteo developed its own production management platform, which it offers as a software-as-a-service (SaaS) solution as well. The company also supports the operation of 2 GW in third-party capacity, mostly photovoltaics.

“We optimize production in an automated way, using artificial intelligence, integrating real-time weather forecast data, capacity data and market data,” Chikán stressed.

The platform includes executing trading activities. The partners don’t have to deal with scheduling and the balancing energy costs, he said. The company makes a renewable electricity product closer to baseload, Alteo’s head asserted.

Slovakia, Croatia, Serbia are primary investment destinations in Alteo’s regional expansion

Early this year, the company unveiled a strategy for expansion in Hungary as well as into Slovakia, Croatia and Serbia as primary investment destinations. Alteo revealed it is interested in Poland, Czechia, Slovenia, Bosnia and Herzegovina, Montenegro and North Macedonia, too.

Chikán said it also aims to position itself in operations and maintenance (O&M), among other segments. Alteo is particularly seeking stable and reliable AI-based aggregator partnerships, he noted. The company has an investment target of up to EUR 3.5 billion by the end of the decade.

Hungary’s MVM inks deal with Çalık Holding, Ansaldo Energia for combined cycle gas turbine power plant

Hungarian power utility MVM signed an agreement with a consortium of Turkey-based conglomerate Çalık Holding and Italian company Ansaldo Energia, which are tasked with building a 1,000 MW combined cycle gas turbine power plant at the Tiszaújváros site in northeast Hungary.

It is the second time this year that MVM contracted the construction of gas-fueled and hydrogen-ready facilities at sites of former power plants running on fossil fuels. Two months ago, the company signed a deal with domestic firms Status KPRIA and West Hungária Bau, and Egypt-based Elsewedy Electric for a 650 MW power combined cycle gas turbine (CCGT) at the Mátra Power Plant.

Now the contract for the development of a modern CCGT power plant was signed by MVM Tisza Power Plant Ltd. of the MVM Group, Çalık Holding, the consortium lead, and Ansaldo Energia.

The agreement marks the beginning of turnkey execution planning, procurement, and construction of what is expected to be Hungary’s most efficient large-scale power plant, the companies said.

Lantos: No new baseload power plant has been built in Hungary in more than 15 years.

The power plant is expected to supply an average of 7,500 GWh of electricity annually. It will also be prepared to use hydrogen.

The two-member consortium was awarded the construction and long-term maintenance of the gas turbines at the public procurement tender.

After the signing, Hungarian Minister of Energy Csaba Lantos lauded the deal as historic, noting that no new baseload power plant has been built in Hungary in more than 15 years.

“The new facility will play an important role in balancing renewable electricity production, thereby supporting the successful energy transition,” he added.

Mátrai: A modern, flexible generation capacity

Károly Mátrai, MVM Group CEO, said a modern, flexible generation capacity would replace the previously decommissioned traditional power plant. Of note, it was a gas power plant.

The facility to be built at the Tiszaújváros site will leverage existing electricity grid connections, a cooling water system, and access to natural gas at a nearby point, Mátrai underscored.

According to Fabrizio Fabbri, Ansaldo Energia CEO, the MVM Tisza power plant will be the country’s most efficient, ready to meet Hungary’s growth and increasing energy needs. He said his company would bring its most advanced gas turbine technology, suitable for hydrogen use.

Ahmet Çalik, President of Calik Enerji Swiss, said the company is honored to contribute to Hungary’s energy supply and enhance its energy security.

Episodes of negative power prices in Slovenia, Romania spread to workdays

Romania registered the first negative day-ahead electricity price for a workday. The phenomenon, which only used to occur on holidays and weekends, has emerged in Slovenia as well.

In spring and autumn, most of Europe occasionally faces periods of excessive power grid loads. The rapid rise in solar and wind power production and the lack of accompanying energy storage and flexibility capabilities are straining the system at times when demand is low. Advanced electricity markets countered the issue by introducing negative prices.

When prices hit zero or go below zero, the seller delivers electricity without compensation or even has to pay to the buyer, respectively. The phenomenon was normally reserved for holidays and weekends, but more day-ahead markets are now experiencing it for workdays as well.

Downward pressure in Romania from strong inflow of negatively priced electricity via Hungary

Romania saw its first such episode yesterday, on Sunday, in the session for today, Profit.ro reported. Prices in its day-ahead market are negative in five out of 24 periods of one hour, between 11:00 and 16:00.

The country is importing at almost 2 GW via Hungary and exporting at up to 1.5 GW to Bulgaria, the news website added. The article notes that renewable energy producers, especially in Germany, where prices are also negative, are exporting to other markets to ease the impact. They usually benefit from subsidies, so generating electricity isn’t necessarily unprofitable even when they sell at a loss.

In addition, shutting down and restarting power plants can be more costly than paying the other side to take excess output.

The level in Romania went to as low as EUR 6.18 per MWh below zero. But the daily average is EUR 76.54 per MWh. The peak, is EUR 198.16 per MWh, between 20:00 and 21:00, when there is no sunlight and prosumers only consume.

Negative prices turn Slovenia’s HSE into electricity consumer

Prices in Slovenia for today also came in negative between 11:00 and 16:oo, which is very rare for a workday, Naš stik reported. Among other factors, the two-day May 1 holiday shortens the current workweek. The lowest, between 14:00 and 15:00, is EUR 6.18 euros per MWh below zero.

In comparison, the lowest price for Sunday on the BSP Southpool exchange was EUR 104 per MWh under zero.

At one point during the Easter holiday, virtually all HSE’s production capacities were offline and the Avče pumped storage hydropower plant was storing electricity from the grid

“Last year, we had 219 hours in Slovenia when prices were negative. This year, we are already at number 72, and we have only just entered the critical period,” said Deputy Director of System Operations of ELES Aleš Donko. The company is Slovenia’s transmission and distribution system operator.

State-owned power utility Holding Slovenske elektrarne (HSE) found itself in an unusual situation during the Easter holidays because of negative prices.

“For a while, we were actually an energy consumer, not a producer, which is our core mission… Virtually all our power plants were shut down, and the Avče pumped storage hydropower plant was pumping water into the upper reservoir at full capacity,” Head of Operation Planning and Management Jernej Brglez said.

Portugal and Spain, which suffered major outages today together with France, both registered negative prices every day in the third week of April.

Also of note, Greece is preparing to introduce negative prices in the balancing market.

Belgrade Energy Forum 2025 – 50 speakers at eight panels to track pace of SEE energy transition

The agenda of the third Belgrade Energy Forum, taking place on May 14-15, has been finalized with the addition of further prominent energy experts and companies. The conference, organized by Southeast Europe’s leading energy news portal, Balkan Green Energy News, will feature eight panels covering key topics in the energy sector, with an impressive lineup of speakers. Make sure you register on time via this link.

The Belgrade Energy Forum will once again be a meeting place for representatives of regional and international institutions and organizations, as well as the business community from across the region, Europe, and the world.

Eight panels featuring more than 50 speakers will offer an overview of the current challenges in the energy sector. Conference participants will hear in-depth analyses of the current situation, but also projections for the future. The thread that connects everything at this year’s BEF is digitalization – it permeates energy production, consumption, and storage and allows enough flexibility for the stable functioning of the energy systems of the future, where renewable energy will dominate.

Chikán: Electricity knows no borders

One of the key speakers at the conference, Alteo Group CEO Chikán Attila, will lead the company’s high-level delegation. Alteo has recently launched a regional expansion drive, aiming to establish a green platform of up to 2 GW in energy production, including operation, software, maintenance, storage, and waste management.

The Hungarian company primarily targets its home market, Slovakia, Croatia, and Serbia.

“Electricity knows no borders, therefore partnerships and collaborations among energy market players are essential, even at the regional level. Such cooperation is vital to ensuring the security and reliability of electricity supply, facilitating the integration of renewable energy sources, and providing essential digital solutions, supported by expertise and professional know-how,” Chikán stressed.

Although at the heart of national energy systems, state-owned power utilities are faced with an environment that has changed and continues to change rapidly. The key shift is the entry of private capital into electricity production through the construction of solar power plants and wind farms.

The energy transition, at this stage, requires cooperation between state power utilities and private companies. With decarbonization as the main objective, the key challenge lies in choosing appropriate strategies and electricity generation technologies.

Moderating the panel will be Dražen Jakšić, Director of the Energy Institute Hrvoje Požar (EIHP).

“The transition to a low-carbon energy system is a key challenge for our region, demanding innovation, investment, and cooperation. As a sponsor of the Belgrade Energy Forum, EIHP is committed to fostering dialogue and driving sustainable energy solutions. I look forward to an insightful discussion,” he stressed.

Jakšić: The transition to a low-carbon energy system is a key challenge for our region, demanding innovation, investment, and cooperation

In recent years, nuclear energy has emerged as a possible alternative. There is hardly a better interlocutor on this topic in the region than Dejan Paravan, the top man of GEN Energija, the Slovenian company developing the Krško 2 nuclear power plant project.

Dušan Živković, CEO of Elektroprivreda Srbije (EPS), will tell us about the Serbian power utility’s plans when it comes to nuclear energy.

Živković: Without decarbonization, the region’s energy sector has no future

“Without decarbonization, there is no future for the region’s energy sector, and that is the biggest challenge ahead of us. It is essential to accelerate decisions and ensure sustainable project financing mechanisms that will provide energy security for every country and power utility in the decades to come. By investing in existing capacities and new renewable energy projects, EPS, as the biggest utility in the region, will make its own contribution to energy security. That’s why we have initiated a transformation process – because we need to be more profitable, more efficient, and fully prepared to tackle any challenge,” Živković pointed out.

The energy transition, in his words, is the path EPS has chosen, and all its plans will align with that goal, based on the belief that the diversification of energy sources and new technologies are essential for achieving it. “These are just some of the key messages I will share with the participants of this year’s BEF,” said Živković.

Eric Scotto, co-founder and CEO of French company Akuo, will share the latest information on the energy transition from across the globe.

The company’s portfolio consists of 1.9 GW of power plants in operation and under construction, with a further 12 GW in the pipeline in more than 20 countries around the world, including a number of countries in the Southeast Europe region.

The integration of the Western Balkans’ electricity markets with the European Union (EU) markets is a process that deserves much greater public attention than it currently receives. It is safe to say that its true importance will become evident only once it is completed.

Full integration will unlock significant synergies, maximizing the benefits of a unified market by enhancing supply security, accelerating the integration of renewable energy sources, and fostering greater competition and transparency.

Moderator Dejan Stojčevski, CTO of the SEEPEX power exchange, says the panel seeks to encourage dialogue on the importance of cross-border collaboration and market efficiency in bolstering energy security and sustainability in the region.

Bislimoski: The time for inspiring speeches is over. Geopolitical developments demand action – now!

Since market integration is largely the job of regulators, the challenges they face will be analyzed by Marko Bislimoski, president of North Macedonia’s Energy and Water Services Regulatory Commission (RKE).

He says that three things are essential for the regional integration of electricity markets into a single European market: investment, investment, and nothing but investment. In his words, the energy crisis demonstrated that limitations become a reality when governments fail to prioritize the implementation of key energy infrastructure capacities in their budgets.

“This past winter, the region faced the highest electricity prices compared to the rest of Europe. Why? Because the implementation of energy investments is not just a ribbon-cutting ceremony. Today, more than ever before, the countries of the former Yugoslavia must demonstrate maturity. These are the years when energy independence will be built through action. The time for inspiring speeches is over. Geopolitical developments demand action – now!” he stressed.

Energy revolution underway – uniting efforts to deliver green, intelligent and sustainable energy solutions

As much as contesting the energy transition may be futile, there are still those who find such a view meaningful, especially in light of certain global political developments. That’s why it is important to give the floor to some of the transition leaders and let them testify that an energy revolution is indeed underway in the region.

The panel’s moderator Mirza Kušljugić – professor, energy expert, and one of the founders of Bosnia and Herzegovina’s Centre for Sustainable Energy Transition Centre (RESET) – goes one step further to show that change is not only happening but also accelerating.

“The key words are a new energy paradigm driven by the four Ds – decarbonization, digitalization, decentralization, and democratization. But now we also have another D: disruption, or radical change in the industry and market caused by technological innovation. Of course, we must focus the discussion – from global processes (China, the US, the EU, the Global South) to where the region stands in all of this,” Kušljugić points out, providing a perfect introduction to the panel.

Turković: It’s more important than ever to have open discussions about real solutions

Aleš Prešern, Vice President and Head of Southeast Europe at Siemens Energy, has worked in the energy sector for more than 20 years. He recalls that digitalization is key, along with grid resilience and electricity transmission.

With nearly 100,000 employees in more than 90 countries, Siemens Energy develops the energy systems of the future, ensuring that the growing energy demand of the global community is met reliably and sustainably. The technologies created in the company’s research departments and factories drive the energy transition and provide the base for one sixth of the world’s electricity generation.

As a leader in renewable energy development, CWP is actively working on several large-scale projects across the SEE region with a total capacity exceeding 7 GW, positioning the company at the forefront of the region’s energy transition. Given its global expertise and insights into the regional energy market, CWP’s contribution to this year’s conference will be invaluable.

Maja Turković, Executive Vice President of CWP Europe, says that BEF 2025 is a key gathering of leading experts driving the energy transition in Southeast Europe.

“As this shift gains momentum, it’s more important than ever to have open, action-driven discussions about real solutions to the challenges and opportunities ahead,” says Turković.

PPAs as a key to renewable energy growth in SEE

Power Purchase Agreements (PPAs) are, like flexibility, a tool for fixing the imperfections of renewable energy sources, and they are recognized as a key mechanism within the new electricity market design. They ensure price stability, attract new investment, and accelerate the decarbonization of industry.

Is the region ready for PPAs? What are the dominant models? What is the current market practice? How are PPAs viewed by financial institutions? What do they offer to end consumers and what to investors in new power plants? Answers to these questions will be sought at the panel moderated by Mislav Slade-Šilović, Energy, Utilities & Resources Consulting Leader for Southeast Europe and member of the core PPA team at consultancy PwC.

Experience with PPAs for more than 500 GWh of electricity

Slade-Šilović’s experience in concluding PPAs for the production and consumption of over 500 GWh of electricity per year in the SEE region will certainly be of help.

Nikola Gazdov, Chairman of Bulgaria’s association for electricity production, storage, and trading (APSTE) and member of the Board of Directors of the European solar industry association SolarPower Europe, has no shortage of experience either. As CEO of three companies – Enery Element GmbH, Element Power Group, and Renergy – he is involved in the development of a large number of projects.

Pexapark, a company that provides logistics to businesses in the renewable energy market, is synonymous with PPAs in Europe. Natalija Ljubić is the Manager for PPA and BESS Transactions at Pexapark, which has helped conclude contracts for facilities with a combined capacity exceeding 35 GW.

The views of electricity buyers – without whom there would be no PPAs – will be conveyed by Ivana Đurović, Category Manager for Renewable Energy at Knauf Group.

Moderating the panel will be Elena Boškov Kovač, co-founder and CEO of Blueprint Energy Solutions, and a leading voice on market flexibility in Europe.

She will host representatives of the sector’s leading companies: NGEN, Alteo, KOER, CyberGrid, as well as Serbia’s transmission system operator Elektromreža Srbije (EMS).

“Excited to moderate a high-impact panel on ‘Market Flexibility: The Backbone of a Resilient Energy System’ at the Belgrade Energy Forum 2025,” says Boškov Kovač, whose work has shaped smart grid strategies and digitalization innovation agendas across the EU and under ETIP SNET.

As Europe accelerates its shift to renewables, market flexibility is emerging as the cornerstone of reliable, affordable, and decarbonized energy systems. With the European flexibility market promising to unlock over EUR 20 billion in savings, this session will explore how digital tools, flexible assets, and new market designs are unlocking value and resilience across the grid.

Slovenia’s NGEN is the technology sponsor of BEF 2025

Slovenian energy company NGEN, the technology sponsor of the conference, has managed to establish itself as a significant player in European markets in just five years of operation and is now ready to enter the Western Balkans’ markets.

Specializing in premium battery storage systems and smart energy solutions, the company is developing systems with a total capacity of 1.6 GWh in European countries. Its founder, Roman Bernard, will be speaking at the panel.

Also taking part in the panel will be Luka Renko, COO of KOER, a pioneer in virtual power plants in the region.

Rounding off the lineup of exceptional panelists will be Nikolaj Candellari, who is responsible for project management at CyberGrid. The software company was acquired a few years ago by Austria’s EVN, one of the first to demonstrate that greater integration of renewable energy sources, battery storage, and prosumers is not possible without digitalization and software solutions.

In a nutshell, this innovative company stands for the digitalization of the energy sector, with a focus on virtual power plants.

Delta Green launches platform in CEE for households to provide grid balancing

Czech energy startup Delta Green has launched a platform enabling households to provide grid balancing for transmission system operators. The company claims it is the first in Central and Eastern Europe and among the first in Europe to implement such a solution.

Delta Green said it just became the first in the CEE region to launch a platform that lets ordinary households help stabilize the energy grid, arguing it’s never been done before at this scale in the region.

The startup stressed the innovation comes at a critical time when European flexibility needs are projected to more than double, from 220 TWh in 2025 to 530 TWh by 2033, according to the latest projections by ENTSO-E.

Flexibility could bring benefits to consumers, and savings to grid operators, but also reduce electricity prices and grid investments.

The platform transforms ordinary households into active participants in the energy market

The platform transforms ordinary households into active participants in the energy market, allowing them to adjust electricity consumption or supply power in response to grid demands – a capability that directly addresses Europe’s growing flexibility challenges, the company underlined.

“A standard home solar system with battery storage can save up to EUR 40 per month. In Germany and France, where millions of homes have solar setups, 10% participation could offset the output of several power plants, reducing fossil fuel reliance and boosting grid resilience,” co-owner and Chief Product Officer of Delta Green Jan Hicl said.

Delta Green says its platform is the Airbnb of grid balancing

The company added its tech is already saving consumers money and reducing fossil fuel reliance. One can think of it as the Airbnb of grid balancing, Delta Green said.

The company is now working on expanding its services beyond the Czech Republic to both Western and Eastern Europe, for example the DACH region (Germany, Austria, and Switzerland), Italy, and Romania.

Delta Green was established in 2008 as Nano Green under the Nano Energies group. It rebranded itself last year. The company is jointly owned by David Brožík, Prokop Čech, Lukáš Beneš, and Jan Hicl.

Demand-side flexibility could deliver over EUR 300 billion in benefits for European consumers

A recent study from the Smart Energy Europe Association (smartEn) demonstrates that demand-side flexibility could deliver over EUR 300 billion in benefits for European consumers by 2030. Grid flexibility from available assets, including household systems, could contribute a projected EUR 4 billion in annual savings for European grid operators.

According to the European Agency for the Cooperation of Energy Regulators (ACER), grid expansion and flexibility measures potentially could reduce electricity prices by 11% by 2035 and by 30% in 2040 in a net zero scenario.

The European Union needs EUR 584 billion in grid upgrades by 2030. Flexibility solutions, combined with grid optimization, could lower the much needed grid investments from an anticipated EUR 67 billion to EUR 55 billion annually between 2025 and 2050.

Energy efficiency: the jack of all trades of EU electrification

By Arianna Vitali, Secretary General at the Coalition for Energy Savings, EUSEW’s partner organisation, highlighting the importance of energy efficiency in EU electrification, including cost savings, better grid flexibility, and protecting consumers.

It is no secret that for the EU to reach climate neutrality, the progressive electrification of our energy system will be essential – and with it, a sound strategy to achieve it in a cost-effective manner. With an Electrification Action Plan on the books for the new European Commission, it is crucial to ensure that the potential of energy efficiency to enable, accelerate, and lower the costs of EU electrification is not overlooked, but rather fully leveraged.

Energy efficiency and electrification: a match made in heaven

Shifting away from fossil fuels and towards renewable energy sources will require accelerating the electrification of both energy production and end-uses. While we all agree that electrification boosts energy efficiency, it is important to remember that this relationship is a two-way street where energy efficiency also has something to offer to the EU electrification process.

Indeed, by reducing overall energy demand, energy efficiency can ease grid congestion, reduce the costs of electrifying the EU energy system, and stabilise the prices paid by consumers. In that vein, the European Commission recently stressed that combined action on electrification and energy efficiency can reduce the EU’s fossil fuel import bill by €32.5 billion every year by 2030 (representing 25% of the total savings that would result from implementing the Action Plan). With the top priorities for this mandate focusing on improving competitiveness and affordability, leveraging the joint potential of energy efficiency and electrification is more relevant than ever.

Flexibility is key

A resilient energy system starts with a flexible energy system. Beyond supporting the EU’s climate neutrality goal, reducing energy demand through demand-side measures eases stress on the grid, allows for more flexible consumption patterns, and ultimately ensures a more adaptable and resilient energy system. The evidence is there: by adopting ambitious demand-side measures (both efficiency and flexibility), peak demand can be reduced by up to 39% in 2030 compared to a scenario without such improvements. This, by extension, lowers the need for additional infrastructure, making the overall electrification process faster and more manageable.

Lowering costs, boosting affordability, and protecting citizens

Energy efficiency’s potential to reduce infrastructure costs, and therefore overall system costs, is significant. For instance, ambitious demand-side measures respectively lower total energy system costs and reduce annual investments in distribution grids by around €40 billion.

These saved costs, which will ultimately not be paid by businesses and citizens, contribute to energy affordability by keeping electricity prices in check, helping European industries decarbonise while improving their competitiveness.

Finally, energy efficiency measures would also cut energy costs for households, helping to protect the most vulnerable. With ambitious demand-side measures, households could save significantly on their annual energy bills. Annual average household energy spending could go down to €900 by 2030, a considerable drop from today’s average of €1,190. This proves particularly useful for heating and road transport, which are expected to increase fossil fuel prices.

Time to put energy efficiency first

The EU transition towards decarbonisation and electrification of the energy system will require careful planning and substantial investment. Luckily, the EU has a jack of all trades on hand. With its wide range of benefits, from reducing infrastructure needs and costs, increasing energy security, cutting energy bills, and supporting both businesses and vulnerable citizens, energy efficiency offers readily available solutions to many of the challenges ahead and must be prioritised.

As stressed in the Action Plan for Affordable Energy, the EU needs a ‘decarbonised energy system, driven by a substantial scale-up of clean energy and electrification, with energy efficiency at its centre’. Prioritising the implementation of energy efficiency solutions on the ground will be key to building an affordable, secure, and competitive energy system for the future.

Solar, nuclear lower Europe’s power prices by 30% in March

Electricity generation in solar and nuclear power plants, combined with higher temperatures, lowered the price of electricity in Europe in March by almost 30% on a monthly basis, according to Eurelectric’s data.

Photovoltaics broke the record in power generation in March for the third consecutive month, Eurelectric said, adding that they accounted for more than 10% of Europe’s electricity mix.

The boost in solar power, combined with improved nuclear generation and milder weather, decreased power prices to EUR 90 per MWh from EUR 126 per MWh, registered in February, and EUR 112 per MWh in January.

The organization attributed high prices in the previous two months to low wind generation, increased power demand and the highest gas prices in two years. Ongoing global geopolitical tensions and outages in Norway exerted upward pressure on the cost of gas while limited storage and flexibility sources forced a heavier reliance on gas to supply electricity.

65 GW of solar was added in 2024

Eurelectric said solar rescued Europe with sunnier days and the rise in capacity, with 65 GW added in 2024 alone. As a result, the share of renewables in the power mix was 15 percentage points higher in March compared to February, though one point lower than in March 2024.

Nuclear energy contributed to the decrease in prices with the rise of its share in power production from 24% in March 2024 to last month’s 26% after a few French nuclear reactors came back online, Eurelectric said.

Nevertheless, the average day-ahead electricity price in the first quarter of 2025 was 51% higher than in the first three months of last year. The surge was primarily driven by higher average gas prices, which grew by 33% in the same period, according to the data.

Ruby: Europe remains too vulnerable to fossil fuel price fluctuations

The organization’s Secretary General Kristian Ruby stressed that Europe remains too vulnerable to fossil fuel price fluctuations, especially during periods of high electricity demand. “To counter this, we must speed up the roll-out of demand side response and storage technologies and further incentivise the use of long-term power purchase agreements,” he noted.

Eurelectric sees solutions in capacity mechanisms and flexibility-supporting schemes. Flexibility is also crucial when it comes to balancing negative prices, which are occurring more frequently. As solar generation rose in March, negative prices made a comeback, particularly in Nordic and Western European countries, the organization of the European electricity industry pointed out.

Prequalification open for 170 MW of battery storage in Kosovo*

Millennium Challenge Account Kosovo invited qualified companies to respond to the prequalification call for a battery storage project. The two lots are for 45 MW and 125 MW in operating power, with a duration of two hours.

The United States, acting through its Millennium Challenge Corp. (MCC) and the Government of Kosovo*, entered into a Millennium
Challenge Compact in 2022. The project contributes to poverty reduction through economic growth. Within the mechanism, a new prequalification call is on until February 14 for the design and build of utility-scale battery energy storage systems (BESS) and transmission connection infrastructure.

The US participates with USD 202 million and the government in Prishtina allocated USD 34.7 million for the entire endeavor. Kosovo* intends to apply a portion to eligible payments under one or two contracts for BESS, the documentation shows.

The contracting authority in the prequalification process is called Millennium Challenge Account Kosovo (MCA-K). The subproject will be instrumental in enhancing the stability of the power grid and improving the management of energy imbalances, the call reads. It is the biggest investment in BESS in the Western Balkans.

Facilities to provide grid services, conduct energy arbitrage

The first lot will be for batteries with 45 MW in capability and a duration of two hours. It translates to 90 MWh in capacity. The second lot is for 125 MW and 250 MWh, respectively.

According to the project presentation MCC released earlier, the first facility will provide automatic frequency restoration reserve (aFRR) services. It would work for the Transmission, System and Market Operator (KOSTT) of Kosovo* and within the Albania-Kosovo (AL-KS) Control Block.

The site for one BESS facility is next to US Army base Camp Bondsteel

The site, near the city of Ferizaj (Uroševac), is right next to Camp Bondsteel. Led by the US Army, it is the seat of the Kosovo Force (KFOR).

The second BESS system would provide ancillary, balancing and other services and conduct energy arbitrage. It would operate under government-controlled Energy Storage Corp. (ESC or ESCorp). The location is in the municipality of Peja or, in Serbian, Peć.

The two future lithium-ion battery systems have budgets of USD 46 million and USD 125 million, respectively, the document shows.

They will be connected to 400/110 kV substations Ferizaj 2 and Peja 3, via underground cables.

Online conference scheduled for December 23

The current announcement adds there would be a prequalification webinar on December 23.

MCC expects to issue the call for bids in July and that construction would start in May 2026. The targeted commercial operation date is August 2028.

Of note, the Millennium Challenge Compact program includes the Just and Equitable Transition Acceleration (JETA) project. It consists of reskilling and the promotion of an inclusive energy sector workforce.

Serbia receives first two grid applications for battery energy storage systems

Serbia’s transmission system operator Elektromreža Srbije received two grid connection applications for battery energy storage systems. They are the first energy storage projects in the country.

Investments in battery energy storage systems (BESS) is ramping up around the world and Serbia is now making its first steps. Annual installations have increased more than 12 times in just four years, projects for an overall 11.5 GWh were announced in only three European countries, and last year China and Germany increased their battery capacity by 130% and 50%, respectively.

The grid connection applications in Serbia were submitted by Green BESS KV, for a 100 MW project of the same name, and MKBDP Energy, for its 50 MW project Skladište električne energije Jagodina.

Applications were submitted by Green BESS KV and MKBDP Energy

Green BESS is a special purpose vehicle (SPV) of Radiant Partners, while MKBDP Energy is part of the MK Group. Of note, there are other energy storage projects in the pipeline, but none of them are as far ahead as them. Both parent companies are registered in Serbia.

MK Group is very active in the renewable energy sector in the country. It put its Krivača wind farm into operation last year.

Serbia’s TSO Elektromreža Srbije (EMS) confirmed to Balkan Green Energy News that it has received the first applications for signing the agreement on the preparation of the connection study for standalone storage.

MKBDP Energy applied for a 50 MW facility located close to Jagodina. The site for Green BESS KV of 100 MW facility is near Kraljevo, according to EMS. Both cities are in the central part of the country.

After signing such an agreement, the TSO starts work on the study, which lasts 120 days.

The start of construction is scheduled for the first half of 2026

According to Green BESS KV, it is an SPV established by consulting firm Radiant Partners, a developer of large-scale renewable energy projects. Radiant Partners is developing one of the largest solar power projects in Serbia – Noćaj, near Sremska Mitrovica, with a capacity of 180 MW, while new solar and wind projects are in the initial phase.

“Our vision is focused on sustainability, innovation, and energy independence. The 100 MW / 200 MWh battery storage facility represents a significant step in the modernization of Serbia’s energy system, contributing to environmental protection and bringing numerous economic benefits,” CEO of Radiant Partners Nikola Ćeha told Balkan Green Energy News.

Batteries are a good market opportunity

In the next phase, the construction of a storage facility after obtaining all the permits, Radina Partners plans to cooperate with Chinese partners. The project is located in Kraljevo, in the vicinity of the TS Kraljevo 3 transformer station. The start of works is scheduled for the first half of 2026.

Asked about motives for the pioneering step, Ćeha explains there are currently no battery storage facilities in Serbia and that interest in renewable energy projects is growing.

“We see a project for supporting existing and future renewable power plants as a market opportunity, given their variability in daily production,” he stated.

Battery storage increases flexibility in the market

He stressed the importance of large-scale BESS units in Serbia, saying they are crucial for balancing production with consumption, in a situation where renewable energy production is increasing. Batteries stabilize the power grid and enable the storage of excess energy and its use in times of higher consumption or lower production.

In his words, batteries increase flexibility in the market because of their quick response to changes in energy consumption and prices, which opens up opportunities for trade and cost optimization.

Such a project attracts investments and encourages the development of energy infrastructure, which contributes to market competitiveness and technological progress, Ćeha said.

Montenegro’s EPCG to launch public call for 300 MWh of batteries

Montenegro’s state-owned power utility, Elektroprivreda Crne Gore (EPCG), intends to invite bids by the end of the year for the installation of battery energy storage systems.

President of EPCG’s Board of Directors Milutin Đukanović has said that the company’s business philosophy is based on three principles – production at the point of consumption, use of hydropower for the integration of solar energy, and energy storage.

Speaking at a conference on regional power companies and their plans for the future, organized by Energija Balkana, Đukanović highlighted batteries as one of the key enablers of the green transition.

“By the end of year, EPCG will announce a public call for the procurement of battery energy storage systems (BESS) with a capacity of 300 MWh,” he said, according to EPCG.

EPCG plans to finish two more large-scale projects by the end of 2026

EPCG also plans to complete two large-scale projects by the end of 2026 – the construction of the Gvozd wind power plant and the installation of the A8 unit in the Perućica hydropower plant, according to him. About a month ago, the company held a groundbreaking ceremony for Gvozd, and in September it secured a loan for a new unit at HPP Perućica.

Energy Minister Saša Mujović recently said that a feasibility study was underway for electricity storage projects. The planned locations are at HPP Perućica, the former Željezara Nikšić steel plant, and the Pljevlja coal mine. These locations have available capacity for grid connections.

In September, EPCG said that it had started preparations to install batteries.

EPCG intends to install lithium-ion batteries

The Board of Directors has adopted a project task proposal and announced the launch of a public call for a feasibility study and project design.

The company plans to secure the flexibility of the power system by developing storage systems based on lithium-ion batteries, EPCG said.
