Workshop on power grid development in Western Balkans held by GIZ, Energy Community Secretariat

The development of grid infrastructure in the Western Balkans is a crucial step in the region’s energy transition. In support of the Green Agenda for the Western Balkans, GIZ, in cooperation with the Energy Community Secretariat, organized a Strategic Workshop on Power Grids, with a focus on a concrete action plan for the entire region.

Without the development of grid infrastructure, large-scale electrification based on clean energy sources is not possible. The process requires significant investments and new solutions for operating the grid. Existing power lines will need to be reinforced, while new infrastructure, especially on low and medium voltage levels, as well as interconnectors, must be built over the next ten years.

The recent large-scale power outage in Southern Europe, and the one in the Western Balkans in 2024, are a stark reminder of the importance of ensuring system stability amid the growing use of renewables and the need for preventive safety measures. A functional and reliable electricity supply is key to gaining broad public support for alternative energy sources and green policies.

The Strategic Workshop on Power Grids, organized by GIZ in Vienna as part of the project Green Agenda: Decarbonization of the Electricity Sector in the Western Balkans, in cooperation with the Energy Community Secretariat, brought together representatives from transmission and distribution system operators, along with experts from the Hrvoje Požar Energy Institute (EIHP), intending to develop the Action Plan for Power Grids in the Western Balkans.

The action plan provides a clear roadmap for grid development in the Western Balkans

Electricity networks in Western Balkan countries were not designed to meet the challenges of the 21st century. Although the countries in the region have adopted very ambitious decarbonization and renewable energy integration targets, around two thirds of electricity generation comes from coal-fired power plants, according to Goran Majstrović, Deputy Director and Head of the Energy Transmission and Distribution Department at EIHP.

“Regional power networks remain constrained by outdated assets, insufficiently utilized interconnection capacities, administrative bottlenecks, and inadequate digitalization. Without urgent and coordinated action, the power network in the Western Balkans will become a serious bottleneck to secure operation and progress rather than a platform for transformation and development,” Majstrović explains.

Without urgent and coordinated action, the electricity network in the Western Balkans could become a serious obstacle to secure operation and progress, instead of being a platform for transformation and development, he warned.

The Western Balkan Action Plan for Power Grids directly addresses the root causes of recent blackouts, including extreme weather events, aging infrastructure, and the growing share of variable renewable energy sources, particularly wind and solar, as their output is sensitive to any changes in weather conditions.

By focusing on grid modernization, regional coordination, and system resilience, the plan offers a concrete roadmap for preventing future outages. It also promotes investment in smart grid technologies, cross-border interconnectors, and digital system monitoring, all of which are essential for adapting to growing demand and fluctuations in electricity production.

The action plan is a strong expression of regional cooperation in the power sector

Crucially, the plan strengthens operational cooperation among system operators across the Western Balkans region, enabling a more flexible and integrated regional grid. In doing so, it lays the foundation for a stable and secure energy transition based on renewables, helping the region become a reliable supplier of clean electricity to Europe.

According to Goran Majstrović, the Action Plan for Western Balkans Grids provides a forward-looking and regionally harmonized strategy to address the challenges. It is built on the vision of the European Union’s Action Plan for Grids and aligns closely with the Sofia Declaration on the Green Agenda for the Western Balkans, the Energy Community framework, and each country’s national energy and climate plan (NECP).

The document is a strong expression of collaboration of the Western Balkans power sector in a matter of high mutual interest – mobilizing attention, human and financial resources for a rapid energy transition, enabled by sustainable, interconnected, and resilient power infrastructure.

Western Balkans power markets: hope for coupling with EU, concerns about CBAM

Energy Community contracting parties are doing their best to meet the challenging requirements and use the opportunity to couple their electricity markets with the European Union in Q4 2026 or Q1 2027. Apart from other benefits, coupling could represent a strong incentive for investment in renewables. However, the introduction of CBAM could be a step back for electricity markets, investments and energy transition in the region, according to representatives of transmission system operators, regulators, and power exchanges who spoke at Belgrade Energy Forum 2025.

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

Participants in the panel called Integration of Western Balkans electricity markets into internal European market through market coupling were:

  • Anže Predovnik, ADEX Group, CEO,
  • Jasmina Trhulj, Energy Community Secretariat, Head of Electricity Unit,
  • Ivan Asanović, TSO Crnogorski Elektroprenosni Sistem (CGES), CEO,
  • Marko Bislimoski, Energy, Water Services and Municipal Waste Management Services Regulatory Commission of the Republic of North Macedonia (RKE or ERC), President,
  • Zoran Vujasinović, EU Agency for the Cooperation of Energy Regulators (ACER), Policy Officer.

They discussed very hot topics including market coupling, the Carbon Border Adjustment Mechanism (CBAM), and blackouts.

Market coupling: The first go-live window scheduled for Q4 2026 or Q1 2027

In his opening remarks, panel moderator Dejan Stojčevski, CTO of the SEEPEX power exchange, emphasized the importance of integrating the electricity markets of the Energy Community contracting parties (EnC CPs) with the EU internal electricity market as a key element in the energy transition process.

“Market coupling, which is a prerequisite for a successful energy transition, brings about greater transparency, increased competition, the establishment of a unified regional reference price, and stronger incentives for investment in renewable energy sources,” he stressed.

However, in his words, the integration is not without challenges. Countries in the region must address several issues, including the transposition of relevant regulations, the designation of nominated electricity market operators (NEMOs), and the operational connection process through the implementation of local projects, Stojčevski underlined.

Trhulj: The transposition of EIP enables accelerated electricity market integration into the single EU electricity market

The most important regulation is the Energy Integration Package (EIP). Jasmina Trhulj, Head of Electricity Unit of the Energy Community Secretariat, recalled that the transposition of EIP by the contracting parties enables their accelerated electricity market integration into the single EU electricity market before accession into the EU takes place.

To achieve that, EnC CPs have to adopt and implement the laws in a compliant manner, including extending ACER’s jurisdiction to the cross-border issues between EU member states and EnC CPs, she noted.

With regard to regional methodologies, ACER is competent to the extent that neighboring EU countries are involved, which is most often the case.

The preparation of the Market Coupling Operator Integration Plan is underway

Another important piece of the puzzle is the Market Coupling Operator Integration Plan (MCO IP), which will set guidelines and timelines for the implementation of the day-ahead and intraday market coupling of EnC CPs. Trhulj confirmed that the preparation is currently underway.

According to the draft MCO IP, the first go-live window is scheduled for Q4 2026 or potentially by Q1 2027, provided that the following prerequisites are met, she revealed.

The prerequisites are the transposition of the EIHP completed and its compliance verified; NEMO designated in a compliant manner; operational readiness of transmission system operators (TSOs) and NEMOs confirmed; and full contractual adherence completed.

“Provided that the legislation is transposed and its compliance verified and MCO IP approved by ACER, a NEMO may submit requests for accession to market coupling. This is followed by an accession process lasting up to 18 months,” Trhulj explained.

Serbia, Montenegro “locked and ready” for the first go-live window

ADEX Group CEO Anže Predovnik shared Slovenia’s experience in various market coupling processes within the internal European electricity market, including different products such as day-ahead, intraday continuous, and intraday auction market coupling.

He particularly emphasized the importance of market coupling and its impact on liquidity, transparency, competition, and increased investments in renewable energy sources.

Predovnik presented HUPX’s integration into the ADEX Group, which was completed in late 2024, and highlighted the benefits ADEX brings to the market and its participants through the unification of the power exchanges of Slovenia, Serbia, and Hungary.

Enhanced transparency, the use of a unified trading and clearing technology, a single market operation, a harmonized market access process across the ADEX markets, alignment of rules, and improved client services are just some of the advantages offered by the formation of ADEX Group, he pointed out.

One immediate benefit already implemented is that market participants active in one ADEX market do not pay entry fees when accessing another market within the group.

Predovnik: Market participants active in one ADEX market don’t pay entry fees when accessing another market within the group

“Additionally, all resources within the group are contributing to the implementation of the local project for coupling the Serbian and Hungarian day-ahead markets, with the project expected to be completed at the first available slot, anticipated for Q4 2026 or Q1 2027,” Predovnik noted.

CEO of Montenegro’s TSO Crnogorski Elektroprenosni Sistem (CGES) Ivan Asanović also spoke about the market coupling project timeframe.

After compliance of the transposition of EIP is verified and provided that the necessary adaptations of the Day-ahead Operations Agreement (DAOA) and the Intraday Operations Agreement (IDOA) regarding the extension to the price zones of EnC CPs are adopted at the Market Coupling Steering Committee (MCSC) level, CGES and power exchange BELEN could sign these contracts, becoming non-operating parties in the MCSC, he revealed.

According to Asanović, obtaining the status in MCSC is a precondition for the submission of a request for change, and it is extremely important to carry it out in a timely manner, to complete the process, which lasts 18 months, until Q4 2026 or Q1 2027.

Of note, a week ago, North Macedonia’s Minister of Energy, Mining and Mineral Resources Sanja Božinovska said it is realistic to aim for coupling in the fourth quarter of 2026 or the first quarter of 2027.

CBAM and blackouts are looming

Apart from market coupling, the stakeholders in the region are also concerned about the developments regarding the Carbon Border Adjustment Mechanism (CBAM) as well as about blackouts.

Dejan Stojčevski (SEEPEX) sees the potential effect of CBAM on the electricity sector, starting on January 1, 2026, as a major issue.

The mechanism could pose a serious threat to the overall energy transition in the region, he added.

In addition, it is crucial to discuss system security and the root causes of the blackouts that recently occurred across Europe, Stojčevski pointed out.

“As there was no announcement that the application of CBAM will be postponed, we are operating under the assumption that it will apply to electricity as of January 1, 2026, given that the contracting parties will not be ready for market coupling by that date,” Jasmina Trhulj (Energy Community Secretariat) underlined.

Trhulj: There is a risk that certain stakeholders may shift their trading activities and renewable investments away from the region

In her words, it creates a number of risks to the functioning of the regional electricity market and the energy transition process that the secretariat has been raising on behalf of the contracting parties, electricity traders, power utilities, renewable energy developers, and other stakeholders.

She warned of a risk that certain stakeholders shift their trading activities and investments in renewables away from the region, thereby potentially undermining integration and decarbonization efforts.

In addition, market participants are raising the issue of the considerable uncertainty regarding the exact technical implementation of CBAM for electricity – inherently unique within a group of goods, Trhulj recalled.

It is crucial for the countries in the region to speak openly with Brussels, said Marko Bislimoski, president of the Energy, Water Services and Municipal Waste Management Services Regulatory Commission of the Republic of North Macedonia. In addition, they need to come up with an action plan, together with the Energy Community Secretariat, defining the phases for the introduction of carbon pricing, in his view.

Bislimoski: We need to define the items for which we need financial assistance from the EU

“We need a serious approach and to say what we can do ourselves, and then immediately make it happen. At the same time, we need to define the items for which we will need financial assistance from the EU,” Bislimoski asserted.

The panelists agreed the region needs to present a single coordinated position on CBAM at an upcoming meeting on July 1 in Brussels.

Bislimoski recalled that North Macedonia recently adopted the new Law on Energy and added that bylaws would follow. The end goal is to provide security and stability in the transmission and distribution of electricity like in the EU, but also to lower the prices of electricity for consumers, he added.

Asanović: It is necessary to take urgent measures to improve coordination in the region

Regarding the issue of blackouts, Ivan Asanović (CGES) emphasized the importance of coordinating transmission capacities and maintenance plans for transmission lines across the wider Balkan region.

He recalled the challenging operational conditions experienced last winter, when exchanges planned along the Greece-Bulgaria-Romania-Hungary corridor were largely physically realized via the southwestern Balkans, leading to significant network stress. Such situations must be avoided through more comprehensive coordination, he warned.

It is necessary, in his words, to take urgent measures to improve coordination in the region to alleviate the current problems until the establishment of the mechanisms and structures prescribed in the CACM and SOGL regulations.

“These rules will fully harmonize the operation of the system in the region with the rest of Europe and significantly improve the security of functioning and create the necessary preconditions for connecting the markets of the WB6 countries with the single European market,” Asanović stressed.

Vujasinović (ACER): Full operational readiness of CCRs is not a prerequisite for market coupling

Zoran Vujasinović and Ivan Asanović

TSOs made a breakthrough in December. They agreed on a Joint Declaration on Regional Coordination. The declaration, facilitated by ENTSO-E, outlined a new comprehensive cooperation framework for the Western Balkans TSOs within South-East Europe.

Zoran Vujasinović, Policy Officer at the EU Agency for the Cooperation of Energy Regulators (ACER), mentioned that in January the body submitted a request to the TSOs to propose the configuration of capacity calculation regions (CCRs), incorporating the bidding zone borders of EnC CPs within the framework of the EU CCR methodology.

The TSOs’ proposal is expected by the end of July, after which ACER will issue a decision within six months, he said.

The current TSO proposal envisions:

  • the inclusion of the southeastern bidding zone borders in the Balkans into the South East Europe (SEE) region, which already includes the borders between Romania, Bulgaria, and Greece.
  • the formation of a separate region in the northwestern part (covering the mutual borders of bidding zones of Serbia, Bosnia and Herzegovina, and Montenegro, as well as their bidding zone borders with the EU), with a perspective of integration into the Central Europe region.
  • the Italy-Montenegro region and the Eastern Europe region (including Ukraine, Moldova, Poland, Slovakia, Hungary, and Romania) to remain unchanged, as defined by the CACM Regulation of the Energy Community.

According to Vujasaninović, ACER’s position is that the entire region should, over time, transition to flow-based capacity calculation and allocation methodologies. However, the initial step will be participation in market coupling based on Net Transfer Capacity (NTC) values.

“It is important to note that full operational readiness of CCRs is not a prerequisite for market coupling. The coupling can proceed based on existing NTC calculation procedures, provided that regional operational security is not compromised at any time and that maximum coordination in capacity calculation is ensured,” Vujasinović stressed.

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.

Kosovo* receives four applications for wind power auction

German, Kosovar, French and Turkish companies submitted documentation to qualify for the first wind power auction in Kosovo*. The plan is for the government to have a share of up to 49% in selected projects.

The Ministry of Economy of Kosovo* has publicly opened the applications within the qualifications call for the first wind power auction. The quota is 50 MW to 100 MW and the plan is to support 150 MW in total in two rounds. Participants will bid for 15-year power purchase agreements (PPAs) and contracts for difference (CfDs).

One applicant is a consortium of Notus Energy, based in Germany, and Stublla Energy from Kosovo*. The ministry also received documentation from Akuo Energy from France and a consortium led by Güri̇ş, headquartered in Turkey. Both companies participated in the first solar power auction as well, held last year.

The fourth one is the Kosovar consortium One Era. However, its application came half an hour after the deadline passed.

“The experience from the first 100 MW solar auction has taught us that only when we offer an opportunity for fair and transparent competition for the private sector, we not only evoke interest from serious and prestigious global companies, but also ensure favorable prices for citizens,” Minister of Economy Artane Rizvanolli said. She expressed commitment to high transparency and competition procedures.

Ministry planning to open final bids in August

The members of the auction commission are from the Ministry of Economy, Ministry of Environment, Spatial Planning and Infrastructure, Energy Regulatory Office (ERO) and Transmission, System and Market Operator (KOSTT). They are responsible for evaluating the applications concerning the financial, legal and technical requirements.

Next in the schedule is a request for proposals, due in March, after the completion of the qualifications phase. The participants can send their technical and financial proposals. The final bids would be opened in August. The maximum price is EUR 80.2 per MWh excluding value-added tax.

Curtailment is subject to financial compensation

The ministry plans to launch the second round by the end of the year. The winners will be obligated to design, build, operate, maintain and decommission wind parks. According to one brochure, the accepted price will be adjusted every 12 months, It will depend on the inflation rate for the sector.

Balancing responsibility is limited to imbalance volumes greater than 10%. Curtailment is subject to financial compensation.

Wind projects would be run by special purpose vehicles (SPVs), firms where the government would have a share of up to 49%. The Ministry of Economy intends to use the funds from the International Monetary Fund’s Resilience and Sustainability Facility (RSF) in the development of the 150 MW. The purpose of the public-private partnership scheme is to reduce risk for private investors.

Velimir Gavrilović, Fortis Energy: We are developing huge portfolio in SEE

Fortis Energy is working on renewable energy projects of 2 GW altogether in Southeast Europe. One half of the planned capacity is for solar and wind power plants in Serbia, Chief Operational Officer Velimir Gavrilović said at Belgrade Energy Forum (BEF 2025).

Turkey-based Fortis Energy’s projects Noćaj 1 and Noćaj 2 in Serbia for solar power plants with battery energy storage systems (BESS) is nearing a ready-to-build status. They are part of its 2 GW under development in the region. “We are developing a huge portfolio of different renewable energy sources in whole Southeast Europe. This is predominantly in Serbia,” COO Velimir Gavrilović said at Belgrade Energy Forum (BEF 2025).

He addded that one half is for photovoltaic plants and the other for wind parks in the country. Gavrilović revealed that the company is investing in 600 MW in Albania, mainly photovoltaics, together with endeavors in Bosnia and Herzegovina and North Macedonia.

Fortis Energy is exploring new projects in Spain and Italy as well. It also operates biogas power plants in Turkey and Serbia, Gavrilović noted.

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

CBAM’s impact still unclear

Among the challenges for investors in the sector, he pointed to the Carbon Border Adjustment Mechanism (CBAM), the European Union’s CO2 tax. Gavrilović stressed that the exact effect on electricity producers remains to be seen, as well as for the consumers of electricity in industrial production in the region.

Fortis Energy’s COO recalled that investors in renewables in Serbia are obligated to secure energy storage to get grid connection and said there are still some bylaws missing to complete the legal framework.

Grid connection contract signed for 110 MW solar power plant with batteries in Serbia

Earlier this month, the company signed a grid connection contract for its Erdevik solar park in Šid, Serbia, of 110 MW in peak capacity. It is planned to include a BESS facility of 31.2 MWh.

The Turkish developer and engineering, procurement and construction (EPC) operator has three wind power projects in the pipeline in the country: Vranje, Gornjak and Juhor.

Fortis Energy has a 79.9 MW solar power plant in operation in Oslomej in North Macedonia, commissioned last year. The connection capacity is 68.7 MW. In February, the company said it contracted a lithium ion BESS facility to be added, with 62 MW in operating power and a two-hour duration.

Largest battery storage system in Balkans commissioned in Bulgaria

A BESS facility of 124.1 MW in operating power was inaugurated in Lovech in Bulgaria. Located next to a photovoltaic park within Balkan Industrial Park, it is part of the country’s first closed licensed power distribution system.

The Bulgarian city of Lovech, northeast of Sofia, hosts the strongest battery energy storage system (BESS) in the Balkans. The Ministry of Energy even said the new facility, with a capability of 124.1 MW and 496.4 MWh in capacity, is the biggest in the European Union.

It is located in the local industrial zone, which also features a photovoltaic park of 106.2 MW in peak capacity and an 86.2 MW connection. The energy systems are part of Bulgaria’s first and only closed licensed distribution network.

Balkan Industrial Zone, with the solar power plant and BESS facility, is controlled by brothers Kiril and Georgi Domuschiev. The two entrepreneurs intend to charge the batteries when the price of electricity is low and use them in peak periods.

Developer won subsidy at tender for standalone energy storage systems

The investment in the energy storage facility, worth EUR 75 million, was conducted by Advance Green Energy. Notably, last month, at the RESTORE tender for standalone BESS, the company won a EUR 29.6 million government subsidy for a EUR 45.5 million project.

The construction took only six months. The facility, which is marking a new stage in Bulgaria’s infrastructure development, consists of lithium iron phosphate (LFP) devices in 16 modules.

Lovech Mayor Stratsimir Petkov claimed the BESS is the fifth-biggest in the world. He said it would contribute to the development of the industrial park.

Minister Stankov wants 10 GWh of batteries online by end of next year

At the inauguration, Minister of Energy Zhecho Stankov stressed that the investment is a step toward reaching 10 GWh in operating battery storage capacity by the end of next year. He added it is significant for flexibility, predictability and balancing of the electricity system in Bulgaria.

“The facility, built from 111 battery containers on the territory of Lovech, will help Bulgaria’s energy system remain the most stable in the region. We are the pillar in the Balkans and in Southeastern Europe that balances electricity systems and we have proven this with actions,” the minister stated. BESS guarantee system security and price stability for households and businesses, providing affordable energy, Stankov asserted.

The solar park of two units, operating since May 2023, is one of the biggest in Bulgaria. The investment was worth EUR 51.2 million. The PV system spans almost 72 hectares, while the industrial park has 131.5 hectares.

In another recent update relevant for the future of the country’s energy storage sector, Stankov revealed there is a third pumped storage hydropower project under development. The sites are in the Rhodope mountains.

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

Branko Zečević (photo: Balkan Green Energy News)

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

Mark Copley (photo: Balkan Green Energy News)

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.

Managing Director of Go2Power Consulting Goran Vukojević moderated the panel discussion

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

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.
