Hidroelectrica installs battery storage facility at its Crucea Nord wind park

Hidroelectrica’s battery energy storage system (BESS) of 36 MW and 72 MWh, co-located with its Crucea Nord wind park in Romania’s southeast, is on track to come online more than a year earlier than initially planned.

The future energy hub around the village of Crucea in Romania’s Dobruja (Dobrogea) region will soon get its first hybrid power plant. Hidroelectrica, the country’s biggest electricity producer, said the BESS project at its only wind park, Crucea Nord, is 80% finished.

It means the battery storage facility is set to enter operation already in May, the state-owned hydropower plant operator said. It earlier planned to launch production in the summer of 2027.

The BESS will have 36 MW in operating power and a two-hour duration. It translates to 72 MWh in capacity. The system is co-located with a 108 MW wind park, built in 2014. Crucea Nord has been making significant losses due to unfavorable balancing obligations.

The contractors are Romania-based Prime Batteries Technology and Enevo Group

All nine units, supplied by domestic battery manufacturer Prime Batteries Technology (PBT), have been installed by December 30, Hidroelectrica revealed. The other contractor in the consortium is Enevo Group. After first setting up a small battery, the utility selected them in April through a tender.

Prime Batteries manufactures lithium-ion batteries and provides energy storage solutions for the automotive, smart grids, and industrial sectors. The startup is headquartered in Cernica near Bucharest. The other company is Romanian as well.

The deal is worth RON 79.8 million (EUR 15.7 million) excluding value-added tax.

Hidroelectrica operates 188 hydropower plants totaling 6.4 GW in capacity. According to Romania’s transmission system operator Transelectrica, the country hosts BESS facilities with an overall capability of 494 MW and a storage capacity of 913 MWh.

ContourGlobal installs 500 MWh standalone BESS facility in Bulgaria

A standalone battery energy storage system of 202 MW and 500 MWh is fully operational and actively participating in Bulgaria’s day-ahead and intraday electricity markets. ContourGlobal built it at its Maritsa East 3 coal plant, using the grid connection of one of its former units. Acting Minister of Energy Zhecho Stankov, who attended the inauguration, said the country added 5 GWh last year and estimated that the overall BESS capacity would hit 15 GWh by mid-2026.

Bulgaria is, with the Czech Republic, Poland and Germany, in the group of only European Union member states in which more than a fifth of electricity is still generated from coal. But the situation is rapidly changing. One of the biggest standalone battery storage installations in Eastern Europe and among the first in Bulgaria recently came online. Located within the ContourGlobal Maritsa East 3 (Maritsa iztok 3) coal power plant, the facility uses the grid connection of a former unit.

Two remained in operation, supplying electricity during periods of peak demand.

The BESS has 202 MW in operating power and a duration of 2.5 hours, translating to 500 MWh, the company said. It inaugurated the battery system in the presence of Acting Minister of Energy Zhecho Stankov.

Stankov: New BESS creates sustainable pathway for evolution of Maritsa East coal complex

The new facility is actively participating in both the day-ahead and intraday national electricity markets, supporting optimized power dispatch and improved balancing of electricity supply and demand, the update adds.

Such projects signify how innovation and existing industrial infrastructure can work together to strengthen grid stability, improve flexibility, and accelerate the integration of renewable energy sources, Stankov stressed. The investment enhances energy security, supports market-based operation, and creates a sustainable pathway for the evolution of traditional energy hubs such as Maritsa East, in his words.

According to the acting minister, Bulgaria added 5 GWh of BESS capacity last year, nearly matching the Chaira pumped storage hydropower plant. He recalled that the overall level is set to reach 15 GWh by mid-2026.

Project materialized in under nine months

The project in Maritsa East 3 received just under EUR 30 million in support through the European Union’s Recovery and Resilience Facility (RRF) and the Bulgarian National Recovery and Resilience Plan (NRRP). The company participated with EUR 44.7 million.

Spanning 2.5 hectares, the installation is part of ContourGlobal’s 3 GWh operational BESS portfolio. The company is owned by KKR.

BYD supplied the 110 battery skids for the battery system, which also includes 28 power conversion system (PCS) and transformer units. ContourGlobal progressed from the final investment decision (FID) to commercial operation date (COD) in less than nine months.

The company is developing a second BESS on the same site, with a matching capability. It has a project for a battery in combination with a solar power plant as well.

Battery energy systems allow for the storage of electricity generated from various sources, including photovoltaic and wind power plants, during periods of low demand and its release back to the grid during peak demand, which helps balance production and consumption and the stable operation of the electricity transmission system.

Coal plants switching to energy storage

AES Corp. is interested in replacing one of the boilers in its AES Maritsa East 1 (AES Maritsa iztok 1) coal plant with a molten salt reactor.

Greece’s government-controlled Public Power Corp. (PPC Group) is already building BESS facilities at its coal plants.

German utility Uniper is planning to build a battery energy storage system at its Heyden coal power plant site in western Germany with Slovenia-based energy solutions provider NGEN.

Thre months ago, International Power Supply (IPS) opened its Factory X1, with a capacity of 3 GWh per year. It is the first gigafactory in Bulgaria for battery energy storage systems. The same company is building another manufacturing facility.

Why CEE is one of most attractive regions for investment in new energy projects

Munir Hassan and Thomas Hamerl, partners in CMS’s world-leading energy practice, discussed the most significant developments in the renewable energy market for 2026 with Balkan Green Energy News.

There is great potential for early movers in the segments of battery storage and ancillary services, according to Munir Hassan, global head of the energy and climate change at CMS (London), and Thomas Hamerl, regional head of energy and climate change at CMS Vienna.

Interconnection and interoperability with the EU’s electricity market will enhance the region’s value for established producers and increase its attractiveness for new investors, they told Balkan Green Energy News.

Beyond grid availability and tariffs, potential investors in renewables and storage focus on the target country’s policy direction and the scalability of projects, Hassan and Hamerl explained.

Investors need advisors who are familiar with international contracts and can navigate local energy markets

Potential investors in renewables and storage do not just look for efficient support with time-sensitive grid availability and network tariffs. They appreciate legal advisors who are familiar with international contracts and can also navigate local energy markets. The current policy direction of the target country and the scalability of projects are more interesting than ever, Hassan and Hamerl asserted.

CMS’s regional footprint and its global network enable it to share expertise across jurisdictions, and its local teams contribute to regulatory initiatives. With over 70 offices worldwide, including 17 offices in CEE region, CMS supports renewable energy developers and investors. The global law firm follows policy developments that are shifting from saturated markets to the CEE region, with the aim of applying best practices and overcoming challenges and bottlenecks beforehand.

Speaking to Balkan Green Energy News, Hassan and Hamerl said companies should ride the investment wave and use opportunities as legal frameworks in Southeast Europe and the wider CEE region are advancing rapidly and opening new market segments.

At CMS’s traditional annual CEE Energy Conference (CEE Energy Conference 2025), held in London in October 2025, most investors were seriously considering to add energy storage to power plants and PPAs for industrial customers.

Data center projects are adding to demand growth in green electricity

Hassan pointed to digital infrastructure as the main driver of demand, even more in SEE than the rest of the CEE region, alongside the decommissioning of coal and gas-fired power plants.

Things are starting to move with data center projects in Slovenia, Croatia and Austria, for example, Hamerl stressed.

“Usually, data center developers are international and well-experienced, bringing technical and commercial know-how. These need not be only global hyperscalers such as Amazon, Google and Microsoft. Smaller data centre operators and telecom companies are strengthening their presence in CEE. They may all seek out the expertise and networks of local infrastructure developers,” he added.

CMS is involved in major projects throughout Southeast Europe

The changes are spurring the need for more resilience in the energy sphere and national sources. It is one of the factors behind the nuclear energy program in Poland, for shielding against geopolitical shocks, according to Hassan.

There are also nuclear power projects in Romania, including an advanced one for a small modular reactor (SMR) system, and Bulgaria, and CMS is involved in all of them. It has also contributed to deals for the giant Vifor wind power endeavor in Romania. Slovenia and Serbia are next.

Financing through debt could contribute to nuclear energy and interconnector projects

Hassan said there is a notable appetite for debt financing in CEE and suggested that the model could contribute to nuclear projects including the ones for SMRs.

“Another relevant development that we see is the development of electricity networks and even interconnectors. There’s a lot of private capital that’s looking to build electricity grids in Southeast Europe and Central and Eastern Europe. But the regimes there are designed for the existing system operators to develop these projects. The difficulty, like here in the UK and other parts of the world, is that they are unable to deliver the infrastructure quickly because they don’t have the resources and financial capability,” he asserted.

Western Europe is comfortable with the idea that private companies can own and run such assets, Hassan underscored and added that transmission upgrades in general could be financed the same way. But TSOs would typically take ownership of transmission system infrastructure including interconnectors.

EU funds would have better effect as loan guarantees

Among the investment appeal factors in CEE, Hassan highlighted the grants via the European Union’s Modernization Fund and Recovery and Resilience Facility (RRF).

“Those sorts of funds are very, very important. I think the governments need to find smart ways of effectively using that money to help create conditions in which you can get private international investment into the region, rather than simply as grant funding. If you give it as a way of, let’s say, underwriting debt, in case there’s a risk issue, that’s a better way, that kind of multiplier effect,” he stressed.

Knowhow for navigating legal frameworks in emerging market segments in CEE

The United Kingdom and other parts of Western Europe are experiencing growth of the markets for new system support services. Southeast Europe and Central and Eastern Europe may follow soon. For instance, Austria is about to introduce a capacity market. Serbia is rolling out an ancillary services market in January 2026, enabling a potential revenue stream for standalone battery energy storage systems (BESS).

“It’s not a mature market yet, but market entrants with the required experience and knowhow, will find a lot of possibilities in the region. If you want to be a first mover or an early mover, you must go there now,” said Hamerl. He added it is an opportunity for battery storage, to support the grid through the flexibility market or frequency restoration and new kinds of services, instead of just arbitrage.

It is much more expensive to expand the power grid than to use energy storage capacity available in the market

Regulatory frameworks are either in place or will very soon be in place, Hamerl noted.

“Batteries play an important role in supporting the grids and saving money because building new grids is always much more expensive than storage capacity in the market. I still see a long way to go for alternatives to batteries,” he said.

The fact is that it takes several years to build a pumped storage hydropower plant, while hydrogen and ammonia production and distribution infrastructure are not sufficiently developed yet.

Photovoltaics, BESS in sharply upward trajectory

Locations for photovoltaics in Southeast Europe are much better than in most parts of Europe, Hamerl underscored, adding that the coastal areas are particularly favorable for wind power.

For instance, experts predict the total operational solar and wind capacity in Montenegro to reach 400 MW by the end of this year. For Croatia, RES generation capacity is expected to increase from 4.7 GW in 2025 to almost 12 GW by 2040.

In Bulgaria, PV capacity jumped fivefold since 2019, to 5 GW, the law firm pointed out and emphasized the surge in both co-located and standalone BESS as well. Forecasts see the segment, currently at 600 MW, to hit 5 GW by the middle of 2026.

CMS Sofia has advised on more than 50% of all installed renewable energy capacities in Bulgaria. One of the clients, Renalfa IPP, has an investment program worth EUR 1.2 billion, involving 1.6 GW in electricity generation assets and 3.3 GWh of battery storage in Bulgaria, Romania, Hungary and North Macedonia.

CMS helping optimize regulations to suit governments as well as investors

There are obviously differences in every country of Central and Eastern Europe, but there are similarities drawing investors into the region, according to Hassan.

“They want to see the revenue risk is dealt with, the technical risks are dealt with, the political risk is kind of dealt with, et cetera. So our job as lawyers is to help people understand the frameworks, but also our local teams are helping to design some of these frameworks. To that extent, we can try and design them upfront in a way that achieves not only what the countries want, the governments want, but also what the international investors will be looking for,” he asserted.

The most important factors for investors are a clear direction of law making and scalability

In his view, the most important factors are a clear direction of lawmaking and regulation – strong policy backing, and scalability, in the sense that a company can do many more projects on the back of the first one.

Hamerl said that the waiting time for grid connection remains one of the most important elements, together with network charges. Investors seek stable grid fees or at least clarity about the pace and way of growth, he stressed.

“They are always asking us about the stability of the grid and the grid usage charges. However, in some markets there is a diversity of federal, provincial, and  local laws requiring different permits. Investors ask themselves in which province it is possible to obtain permits in time. Zoning and spatial planning is crucial too. For most of our clients, it’s nice to get subsidies, but those other issues are more important,” Hamerl asserted.

Belgium’s former Ministry of Energy Tinne Van der Straeten to become CEO of WindEurope next month

WindEurope’s new Chief Executive Officer Tinne Van der Straeten, member of the Chamber of Representatives of the Federal Parliament of Belgium and the country’s former minister of energy, will assume office on February 2. She is replacing Giles Dickson. The EU added 13 GW of wind capacity in 2025, less than half of what it requires.

WindEurope appointed Tinne Van der Straeten as its new CEO, effective on February 2. The organization pointed out that Belgium’s former minister of energy, from 2020 to 2025, is taking the helm at a critical time for Europe’s energy security, industrial competitiveness and climate commitments.

Tinne Van der Straeten oversaw Belgium’s wind energy expansion, including a broad consensus on Belgium’s response to the energy crisis in 2022, the announcement adds. She chaired the North Seas Energy Cooperation in 2020 and at the start of 2025 and the European Energy Council in 2024, and vice-chaired the ministerial meeting of the International Energy Agency (IEA) in 2022.

Most recently, the former minister served as a member of the Chamber of Representatives of the Federal Parliament of Belgium. She is a member of the Flemish Green Party – Groen.

Wind energy is central to Europe’s energy independence

Van der Straeten said she would take on her new responsibility with determination at a defining moment for Europe.

“Wind energy is central to Europe’s energy independence, industrial competitiveness and climate ambitions. Wind is a home-grown and scalable technology. It delivers affordable power, strengthens energy independence and sustains a competitive industrial base with high-quality jobs across Europe,” the incoming chief said.

Former CEO Giles Dickson served ten years

WindEurope’s Chairman Henrik Andersen praised Tinne Van der Straeten for passionately ensuring wind was kept high on the political agenda in her home country of Belgium and across the European Union.

“She has collaborated across industry and government to shape energy policy and build positive long-term investment frameworks that enable sustainable wind deployment. I look forward to working with Tinne as she leads WindEurope forward and supports Europe’s journey to a more competitive, homegrown energy system together with its members,” he stated.

The WindEurope Board thanked former CEO Giles Dickson for his 10 years of leadership and contribution to Europe’s wind industry.

Affordability, competitiveness, security

Van der Straeten will focus on ensuring Europe gets the most from wind to deliver affordability, industrial competitiveness and energy security, the organization said.

Faced with mounting geopolitical challenges, the continent must shake its dependence on imported fossil fuels, WindEurope stressed.

“Wind is uniquely placed to deliver that. A renewables-based energy system, with wind at its core, will save Europe up to EUR 1.6 trillion, even when counting the grid and backup costs. To reap these benefits, Europe must deliver on the Clean Industrial Deal, accelerate the buildout of homegrown and competitive renewables and ramp up the electrification of its economy,” the update reads.

Today wind energy generates 20% of all electricity consumed in Europe. With the right policies, the level will rise to 34% by 2030 and more than 50% by 2050, WindEurope estimated.

The EU installed 13 GW of new capacity in 2025. It is less than half of what Europe needs to deliver its 2030 energy security and climate targets.

“The wind sector is at a turning point. The industry is ready to accelerate and to provide more than 600,000 jobs by 2030. But it is held back by permitting issues and infrastructure delays,” said Tinne Van der Straeten.

Albania gives green light to CWP Europe for 600 MW wind park

Prime Minister of Albania Edi Rama and Deputy Prime Minister and Minister of Infrastructure and Energy Belinda Balluku promoted CWP Europe’s wind power project Tropoja of 600 MW. After receiving the ministry’s preliminary approval at the event, the company’s CEO Dimitar Enchev highlighted the importance of local electricity production for a modern economy, including AI and data centers, and for energy independence. Albania still doesn’t host a single operational wind turbine.

CWP Europe will hopefully connect its future wind park Tropoja to the grid within 12 months, excluding the period of harsh winter, according to Albania’s Prime Minister Edi Rama. Speaking at the project’s presentation, he said the investment is a step toward the country’s ambition of becoming self-reliant in energy production.

“For a long time, we had complete dependence on water and rainfall. At the same time, we inherited a system with so many weaknesses that, when rainfall was lacking, we had to go to international markets and purchase large quantities at inflated prices. Meanwhile, when rainfall came in abundance, we often saw much of this potential value, water, go to waste and not only fail to be converted into energy, but at times also cause extraordinary damage,” Rama stated.

Namely, hydropower plants accounted for almost 100% of domestic electricity production until recently. By the end of the decade, the combined share of wind and solar power will reach 30%, Rama underscored.

Preparing final stages of Tropoja wind power project

CWP Global’s Co-founder and Chief Executive Officer for Europe Dimitar Enchev received a preliminary approval from the Ministry of Infrastructure and Energy at the event. He highlighted the importance of local electricity production for a modern economy and energy independence, especially with the expansion of artificial intelligence and data centers.

“The last time I was here was about three months ago, when we decided and signed a joint cooperation agreement with the EU. And now, after three months, we receive the permission that allows us to engage in preparing the final stages of our project,” Enchev stated, as quoted by CNA.

CWP Europe has more than 7 GW under development in Southeast Europe

CWP Europe has 900 MW in wind power projects under development in Albania, part of a portfolio of more than 6 GW across Southeast Europe plus more than 1 GW in photovoltaics.

The Tropoja area is in the country’s far north. Albania still doesn’t host a single operational wind turbine.

Support from European Commission

CWP Europe signed a joint declaration in October with the European Commission, the Albanian Investment Development Agency and the Montenegrin Investment Agency, in support of the Tropoja project and the Montechevo solar farm with battery storage in Montenegro, respectively.

In September, the company’s subsidiary Eralb Invest submitted its wind power project to the Ministry of Infrastructure and Energy, for 603.9 MW. It is not subject to concession and doesn’t benefit from state support measures.

In 2023, the firm sent a proposal to the Strategic Investment Committee (SIC or KIS) in which the project was for a wind and solar park of 826 MW in total capacity. It is an interministerial panel chaired by Prime Minister Edi Rama.

The entire designated area in Tropoja municipality reportedly spanned 385 hectares, encompassing the territories of the villages Viçidol, Berisha, Luzha and Pac, and the investment was valued at EUR 1.2 billion.

In October 2023, CWP and GE Vernova’s Onshore Wind business agreed to develop a large-scale hybrid wind and solar project in Albania. They estimated the investment at more than EUR 1 billion.

Fântânele-Cogealac-Gradina, the biggest onshore wind park in Southeastern Europe and, until recently, in entire Europe, has 600 MW in capacity. It is located in Romania. CWP developed the project and sold it in 2008.

Balluku: Diversification is strategic necessity

Albania is moving to a modern, balanced energy model, where diversification of sources is no longer a solution, but a strategic necessity, according to Deputy Prime Minister and Minister of Infrastructure and Energy Belinda Balluku.

“The Tropoja wind farm is not just an energy investment. It is a symbol of the transformation that Albania is experiencing, a transformation towards a sustainable, stronger and more innovation-friendly economy. This project proves that the Albanian energy sector is entering a new phase, where private investment and foreign direct investment are becoming engines of growth, thanks to serious partnerships and long-term visions,” she stated.

Wind and solar power projects totaling 1.5 GW are under development in Albania

In recent years, Albania added over 700 MW of photovoltaic capacity, and another 400 MW for self-supply, Balluku revealed. Wind and solar power projects totaling 1.5 GW are under development, she added. Future pumped storage hydropower capacity in the Drin (Drim) cascade and Statkraft’s project in Moglica amount to 1.6 GW, Balluku stressed.

Since 2013, losses in the power distribution network have dropped to 16.9% from more than 45%, while total electricity capacity increased by 1.5 GW, the deputy prime minister added. She said outages have been reduced to an all-time low and that they usually only last a few minutes.

The Special Court Against Corruption and Organized Crime suspended Balluku in late November amid an investigation, but the Constitutional Court soon reinstated her.

She chaired the North Seas Energy Cooperation in 2020 and at the start of 2025 and the European Energy Council in 2024, and vice-chaired the ministerial meeting of the International Energy Agency (IEA) in 2022.

Most recently, the former minister served as a member of the Chamber of Representatives of the Federal Parliament of Belgium. She is a member of the Flemish Green Party – Groen.

Wind energy is central to Europe’s energy independence

Van der Straeten said she would take on her new responsibility with determination at a defining moment for Europe.

“Wind energy is central to Europe’s energy independence, industrial competitiveness and climate ambitions. Wind is a home-grown and scalable technology. It delivers affordable power, strengthens energy independence and sustains a competitive industrial base with high-quality jobs across Europe,” the incoming chief said.

Former CEO Giles Dickson served ten years

WindEurope’s Chairman Henrik Andersen praised Tinne Van der Straeten for passionately ensuring wind was kept high on the political agenda in her home country of Belgium and across the European Union.

“She has collaborated across industry and government to shape energy policy and build positive long-term investment frameworks that enable sustainable wind deployment. I look forward to working with Tinne as she leads WindEurope forward and supports Europe’s journey to a more competitive, homegrown energy system together with its members,” he stated.

The WindEurope Board thanked former CEO Giles Dickson for his 10 years of leadership and contribution to Europe’s wind industry.

Affordability, competitiveness, security

Van der Straeten will focus on ensuring Europe gets the most from wind to deliver affordability, industrial competitiveness and energy security, the organization said.

Faced with mounting geopolitical challenges, the continent must shake its dependence on imported fossil fuels, WindEurope stressed.

“Wind is uniquely placed to deliver that. A renewables-based energy system, with wind at its core, will save Europe up to EUR 1.6 trillion, even when counting the grid and backup costs. To reap these benefits, Europe must deliver on the Clean Industrial Deal, accelerate the buildout of homegrown and competitive renewables and ramp up the electrification of its economy,” the update reads.

Today wind energy generates 20% of all electricity consumed in Europe. With the right policies, the level will rise to 34% by 2030 and more than 50% by 2050, WindEurope estimated.

The EU installed 13 GW of new capacity in 2025. It is less than half of what Europe needs to deliver its 2030 energy security and climate targets.

“The wind sector is at a turning point. The industry is ready to accelerate and to provide more than 600,000 jobs by 2030. But it is held back by permitting issues and infrastructure delays,” said Tinne Van der Straeten.

Albania gives green light to CWP Europe for 600 MW wind park

Prime Minister of Albania Edi Rama and Deputy Prime Minister and Minister of Infrastructure and Energy Belinda Balluku promoted CWP Europe’s wind power project Tropoja of 600 MW. After receiving the ministry’s preliminary approval at the event, the company’s CEO Dimitar Enchev highlighted the importance of local electricity production for a modern economy, including AI and data centers, and for energy independence. Albania still doesn’t host a single operational wind turbine.

CWP Europe will hopefully connect its future wind park Tropoja to the grid within 12 months, excluding the period of harsh winter, according to Albania’s Prime Minister Edi Rama. Speaking at the project’s presentation, he said the investment is a step toward the country’s ambition of becoming self-reliant in energy production.

“For a long time, we had complete dependence on water and rainfall. At the same time, we inherited a system with so many weaknesses that, when rainfall was lacking, we had to go to international markets and purchase large quantities at inflated prices. Meanwhile, when rainfall came in abundance, we often saw much of this potential value, water, go to waste and not only fail to be converted into energy, but at times also cause extraordinary damage,” Rama stated.

Namely, hydropower plants accounted for almost 100% of domestic electricity production until recently. By the end of the decade, the combined share of wind and solar power will reach 30%, Rama underscored.

Preparing final stages of Tropoja wind power project

CWP Global’s Co-founder and Chief Executive Officer for Europe Dimitar Enchev received a preliminary approval from the Ministry of Infrastructure and Energy at the event. He highlighted the importance of local electricity production for a modern economy and energy independence, especially with the expansion of artificial intelligence and data centers.

“The last time I was here was about three months ago, when we decided and signed a joint cooperation agreement with the EU, and now, after three months, we receive the permission that allows us to engage in preparing the final stages of our project,” he stated, as quoted by CNA.

CWP Europe has more than 7 GW under development in Southeast Europe

CWP Europe has 900 MW in wind power projects under development in Albania, part of a portfolio of more than 6 GW across Southeast Europe plus more than 1 GW in photovoltaics.

The Tropoja area is in the country’s far north. Albania still doesn’t host a single operational wind turbine.

Support from European Commission

CWP Europe signed a joint declaration in October with the European Commission, the Albanian Investment Development Agency and the Montenegrin Investment Agency, in support of the Tropoja project and the Montechevo solar farm with battery storage in Montenegro, respectively.

In September, the company’s subsidiary Eralb Invest submitted its wind power project to the Ministry of Infrastructure and Energy, for 603.9 MW. It is not subject to concession and doesn’t benefit from state support measures.

In 2023, the firm sent a proposal to the Strategic Investment Committee (SIC or KIS) in which the project was for a wind and solar park of 826 MW in total capacity. It is an interministerial panel chaired by Prime Minister Edi Rama.

The entire designated area in Tropoja municipality reportedly spanned 385 hectares, encompassing the territories of the villages Viçidol, Berisha, Luzha and Pac, and the investment was valued at EUR 1.2 billion.

In October 2023, CWP and GE Vernova’s Onshore Wind business agreed to develop a large-scale hybrid wind and solar project in Albania. They estimated the investment at more than EUR 1 billion.

Fântânele-Cogealac-Gradina, the biggest onshore wind park in Southeastern Europe and, until recently, in entire Europe, has 600 MW in capacity. It is located in Romania. CWP developed the project and sold it in 2008.

Balluku: Diversification is strategic necessity

Albania is moving to a modern, balanced energy model, where diversification of sources is no longer a solution, but a strategic necessity, according to Deputy Prime Minister and Minister of Infrastructure and Energy Belinda Balluku.

“The Tropoja wind farm is not just an energy investment. It is a symbol of the transformation that Albania is experiencing, a transformation towards a sustainable, stronger and more innovation-friendly economy. This project proves that the Albanian energy sector is entering a new phase, where private investment and foreign direct investment are becoming engines of growth, thanks to serious partnerships and long-term visions,” she stated.

Wind and solar power projects totaling 1.5 GW are under development in Albania

In recent years, Albania added over 700 MW of photovoltaic capacity, and another 400 MW for self-supply, Balluku revealed. Wind and solar power projects totaling 1.5 GW are under development, she added. Future pumped storage hydropower capacity in the Drin (Drim) cascade and Statkraft’s project in Moglica amount to 1.6 GW, Balluku stressed.

Since 2013, losses in the power distribution network have dropped to 16.9% from more than 45%, while total electricity capacity increased by 1.5 GW, the deputy prime minister added. She said outages have been reduced to an all-time low and that they usually only last a few minutes.

The Special Court Against Corruption and Organized Crime suspended Balluku in late November amid an investigation, but the Constitutional Court soon reinstated her.

ContourGlobal installs 500 MWh standalone BESS facility in Bulgaria

A standalone battery energy storage system of 202 MW and 500 MWh is fully operational and actively participating in Bulgaria’s day-ahead and intraday electricity markets. ContourGlobal built it at its Maritsa East 3 coal plant, using the grid connection of one of its former units. Acting Minister of Energy Zhecho Stankov, who attended the inauguration, said the country added 5 GWh last year and estimated that the overall BESS capacity would hit 15 GWh by mid-2026.

One of the biggest standalone battery storage installations in Eastern Europe and among the first in Bulgaria recently came online. Located within the ContourGlobal Maritsa East 3 (Maritsa iztok 3) coal power plant, the facility uses the grid connection of a former unit. Two remained in operation, supplying electricity during periods of peak demand.

The BESS has 202 MW in operating power and a duration of 2.5 hours, translating to 500 MWh, the company said. It inaugurated the battery system in the presence of Minister of Energy Zhecho Stankov.

Stankov: New BESS creates sustainable pathway for evolution of Maritsa East

The new facility is actively participating in both the day-ahead and intraday national electricity markets, supporting optimized power dispatch, improved balancing of electricity supply and demand, and the integration of renewable energy sources, while enhancing overall system stability and flexibility, the update adds.

Such projects signify how innovation and existing industrial infrastructure can work together to strengthen grid stability, improve flexibility, and accelerate the integration of renewable energy sources, Stankov stressed. The investment enhances energy security, supports market-based operation, and creates a sustainable pathway for the evolution of traditional energy hubs such as Maritsa East, in his words.

According to the acting minister, Bulgaria added 5 GWh of BESS capacity last year, nearly matching the Chaira pumped storage hydropower plant. He recalled that the overall level is set to reach 15 GWh by mid-2026.

Project materialized in under nine months

The project in Maritsa East 3 received support through the European Union’s Recovery and Resilience Facility (RRF) and the Bulgarian National Recovery and Resilience Plan (NRRP). Spanning 2.5 hectares, the installation is part of the company’s 3 GWh operational BESS portfolio. ContourGlobal is owned by KKR.

BYD supplied the 110 battery skids for the battery system, which also includes 28 power conversion system (PCS) and transformer units. ContourGlobal progressed from the final investment decision (FID) to commercial operation date (COD) in less than nine months.

The company is developing a second BESS on the same site, with a matching capability. It has a battery project in combination with a solar power plant as well.

Battery energy systems allow for the storage of electricity generated from various sources, including photovoltaic and wind power plants, during periods of low demand and its release back to the grid during peak demand, which helps balance production and consumption and the stable operation of the electricity transmission system.

Three months ago, International Power Supply (IPS) opened its Factory X1, with a capacity of 3 GWh per year. It is the first gigafactory in Bulgaria for battery energy storage systems. The same company is building another manufacturing facility.
