Reverse energy flows turn Slovenian distributors into power producers

On May 1 and 2 this year, for the first time ever, five Slovenian power distribution companies fed more electricity into the transmission network than they drew from it. This shift is creating challenges for distribution grid operators while also highlighting the core reality of the energy transition.

Indeed, the circumstances were extraordinary during the first two days of May, writes Slovenia’s Naš stik. The weather was clear, but not warm enough for people to use air conditioners, while solar power plants connected to the distribution grid were generating electricity at nearly full capacity.

Industrial plants were not working due to the holiday, and many people were away from home, so electricity consumption from the transmission network fell sharply, reaching only 150 MW between 12 and 1 p.m. In winter, peak hourly consumption reaches around 2,200 MW.

Pumped storage hydropower plant Avče was operating at full capacity

Pumped storage hydropower plant Avče was operating at full capacity, receiving 157 MW from the transmission network. All Slovenian power distribution companies supplied more electricity to the transmission network than they received from it.

Elektro Ljubljana and Elektro Primorska drew energy from the transmission grid, but Elektro Maribor, Elektro Celje, and Elektro Gorenjska delivered significant amounts, resulting in a negative overall balance.

For four hours, the distribution network was a net electricity producer

The distribution network as a whole was a net producer of electricity for four hours on May 1, between 11 a.m. and 3 p.m. On the same day last year, the minimum hourly load of the transmission network was 770 MW, and power distribution companies drew 450-500 MW from the grid. The same thing happened on May 2.

It is worth noting that the total capacity of solar power plants in Slovenia is 1.4 GW, half of which was installed in 2023 and 2024, with the largest part connected to the distribution grid. The overall electricity generation capacity in Slovenia is 7.47 GW.

Managing voltage profiles on the grid poses the greatest challenge

The most pronounced change in energy flows was recorded at Elektro Celje. Boštjan Turinek, director of operations and development, said that a reverse flow of energy from the distribution network to the transmission network was first recorded in July 2022. At that time, the amount was minimal, around 4 MW.

However, in 2023, the reverse flow reached 40 MW, and this year it has already hit 100 MW. The biggest challenge, he explains, is managing voltage profiles on the grid.

The distribution network was built for one-way “traffic” – toward the end user – with the highest voltage at substations and the lowest at end consumers. The mass integration of distributed energy sources has disrupted these voltage profiles, Turinek stressed.

Distributed power plants like emergency vehicles

Ordinary consumers usually don’t notice this – perhaps only a slightly shortened lifespan of their LED bulbs, he said. However, according to him, solar power plant owners often experience automatic inverter shutdowns caused by overvoltage.

Besides holidays, changes in energy flows also occur during collective shutdowns of Slovenian industrial plants during the summer and spring breaks. If the weather is sunny at that time, the output from distributed energy sources is very high.

Turinek recalls that distributed power plants have been granted the same rights as emergency vehicles, so their output always takes priority, regardless of the state of the grid.

If the power system is to be properly managed, he adds, these plants should be placed on an equal footing with all others.

The net metering system for prosumers has had many positive effects, but it has also created numerous problems, Turinek concluded.

PPC launches first tender for pumped storage hydropower plant in former lignite mine

Greek Public Power Corporation (PPC or DEI) is moving forward with a pumped storage hydroelectric project at the site of its former open pit lignite mine Kardia, in a coal region in Western Macedonia.

The government-controlled power utility is seeking a design, supply, construction and commissioning contractor.

PPC announced that another tender would take place as part of the EUR 430 million project, for the ground works and civil engineering.

The criteria are strict. The company said eligible firms have completed at least one pumped storage hydropower station in the European Union within the last ten years, with a capacity of at least 70 MW and a water head of 90-450 meters. Alternatively, the requirement is at least three facilities of the same size in the last 20 years.

Interested parties can submit their proposals until October 20.

PPC’s project in Kardia received an environmental license in May from the Ministry of Environment and Energy. According to the document, there would be one upper and one lower reservoir with tunnels and a 400 kV substation. The ministry approved an “average” 130 MW capacity with an eight-hour duration, and a “maximum” of 148 MW, without defining the two features.

However, the tender sets the capacity at 320 MW, consisting of four 80 MW reversible turbines.

Apart from Kardia, PPC is planning a pumped storage hydropower system in the South Field lignite mine of Kozani, also in the country’s north, with a capacity of 227 MW and a budget of EUR 310 million. The project has also received an environmental license.

The company unveiled a EUR 5.8 billion investment program in April for both coal regions in Greece. It includes 300 MW of battery storage, 2.1 GW in photovoltaics and a 300 MW data center.

Serbia’s EPS reports EUR 234 million profit for first half of 2025

Elektroprivreda Srbije achieved a profit of RSD 27.4 billion (EUR 233.8 million) in the first half of 2025.

The financial result of the state-owned Elektroprivreda Srbije (EPS) is lower than in the same period of 2024, when profit amounted to RSD 32.8 billion (EUR 280.3 million). The company posted RSD 26.1 billion (EUR 222.8 million) in net income for the entire year.

The Ministry of Mining and Energy said the shareholder assembly of the Serbian joint stock company EPS has adopted the report on the implementation of its three-year business plan for the first six months of 2025, declaring a profit of RSD 27.4 billion (EUR 233.8 million).

Minister of Mining and Energy Dubravka Đedović Handanović, the sole shareholder assembly member, noted that the trend of continuous production and financial stability of the company has continued, and highlighted the importance of the results achieved in the mining sector.

The priority is to prepare machinery for the new Radljevo mine in the Kolubara basin

Coal production exceeded the plan by 8%, but more importantly, the year-over-year rise in coal production was 7%, according to Đedović Handanović.

However, in her words, it is crucial to continue the same pace, which is why great effort must be put into completing the machinery preparation project for the new Radljevo mine in Kolubara, so that overburden production can begin next year.

Reduced costs for coal procurement from outside the company

She said that through careful management of the electricity portfolio, coal stocks in depots have been maintained at a high level, around 1.68 million tons. The costs of purchasing coal from third parties are RSD 1.35 billion (EUR 11.5 million) lower than planned and significantly lower than in the past three years, Đedović Handanović said.

The minister highlighted the fact that hydrology has been unfavorable for the second consecutive year, affecting electricity production.

She recalled that in the first quarter of this year, the Petka solar power plant in Kostolac was put into trial operation. Soon, the blades of EPS’s first wind farm will be spun for testing, she Đedović Handanović added.

EPS investing in a subsidiary in Kosovo and Metohija

“It is essential to improve the management of investment activities, especially considering that work is underway on the most significant energy project – the construction of the Bistrica pumped storage hydropower plant. At the same time, it is important to continue efforts to reduce operational costs and improve customer relations,” the minister stressed.

She revealed that as part of the company’s transformation process, key performance indicators (KPIs) were introduced for executive and middle management.

The EPS assembly also approved the decision to invest in the capital of Elektrosever, the company’s subsidiary in Kosovo and Metohija.

That way it enables supplying Serbia’s citizens in four municipalities in the province’s north, she explained. More than 45% of consumers got smart meters by now from Elektrosever, the ministry stressed.

Greek coal region of Megalopolis opens new chapter after lignite

Last year, for the first time in decades, no smoke rose out of coal plants in the Peloponnese peninsula. The last two units had 500 MW together. Megalopolis is one of the two coal regions in Greece, along with Western Macedonia in the country’s north.

According to Public Power Corporation (PPC or DEI) the units Megalopolis-3 and Megalopolis-4 have now been permanently retired. Under the government-controlled utility’s plan to phase out coal completely next year, all such power plants stopped operating by now, with the exception of Ptolemaida 5, of 660 MW, which entered into operation last year. To maintain the security of supply, two units are kept in reserve, also in Western Macedonia in northern Greece.

PPC has produced a study for the reconstruction of the Megalopolis thermal power station, intending to accommodate other activities. Similar works are already underway in the local lignite mine.

New energy investments underway

The group’s investment plan involves various renewable energy and storage projects in Megalopolis to support the area’s energy transition. It is building two photovoltaic farms of 125 MW each, as part of a 490 MW cluster in the area.

The plan includes a 181 MW pumped storage hydropower station in the former lignite mine.

Based on the government’s Just Transition Development Program, Megalopolis will also host a battery factory, by Enercells, as well as two data centers, by Eunice and Kiefer, of 5 MW each. The investments have been approved by the Ministry of Economy and Finance, to seek funding from the European Union’s Just Transition Fund (JTF).

PPC expressed the belief that data centers are important for coal regions. Earlier this year, the group’s CEO George Stassis said they are ideal for such investments as the land and grid connections are already available. PPC is planning a 300 MW data center in Western Macedonia, but it hasn’t announced anything similar for Megalopolis yet.

Heatwave strains European grid, brings profit to energy storage operators

Record solar power production, backed by yet insufficient energy storage capacity, helped maintain the stability of the electricity system in Europe during the latest heatwave, Ember said. Many nuclear and other thermal power plants reduced their activity as river water temperature wasn’t low enough for efficient cooling. Intraday price spreads at European power exchanges landed a windfall for owners of battery energy storage systems and pumped storage hydropower plants.

The heatwave since late June has caused stress for European power systems, driving electricity demand and doubling daily power prices. Yet grids remained stable, fueled by record volumes of solar, think tank Ember pointed out in a report.

Outside temperatures jumped to more than 40 degrees Celsius, triggering an increase in electricity demand as the use of air conditioners soared. Outages in nuclear and thermal power plants exacerbated the challenges.

Daily electricity demand on July 1 was by up to 6% higher in Germany, 9% in France and 14% in Spain than on June 24. As for peak demand, it jumped by 12% in France, 15% in Spain, and 5% in Germany and Poland.

A bigger electricity price spread within one day means higher income for operators of battery energy storage systems

The average daily price surged 15% in Spain, 106% in Poland, 108% in France and 175% in Germany.

“Despite the huge pressure, European grids passed the stress test, and solar electricity played a major role in keeping them running. The surplus of solar energy during the day helped prevent blackouts. However, the use of energy storage is still insufficient, leading to reduced energy supply after sunset. This translated into a sharp increase in electricity prices,” said Ember’s Europe Programme Director Paweł Czyżak.

Record EU solar generation helps keep power supply stable

June saw the highest solar generation on record in the European Union – 45 TWh, which kept the grid well-supplied during daytime hours. The result was 22% up from one year before.

“Heatwaves will not go away – they will only get more severe in the future. Solutions that can help mitigate their impacts, such as battery storage, interconnection, demand flexibility and dynamic tariffs, should become a key part of grid planning and power market design,” Czyżak added. The biggest opportunity is to store solar electricity, to help power air conditioning well into the evening, he stressed.

Outages limited but still posing concern

The overheating of cables is the likely cause of power outages in Italy on July 1. With rising air and water temperatures, the cooling of thermal power plants becomes more challenging as well. It led to forced reductions in electricity generation from nuclear power plants in France and Switzerland.

The French nuclear fleet has been impacted the most, with all but one of the 18 facilities experiencing some type of capacity reduction. According to the update, up to 15% of the capacity may have been impacted.

A blackout of several hours struck large parts of the Czech Republic including Prague on July 4. However, the authorities only blamed it on a transmission cable in the country’s northwest falling, and the resulting domino effect. Notably, the air temperature was much lower than in previous days.

Sun brings power alongside heat

In the peak days of the heatwave in Germany, solar delivered 50 GW and even more, generating 33% to 39% of Germany’s electricity. The country hosts 14 GW of battery energy storage systems (BESS) and 10 GW of pumped storage, which partly bridged the gap between the peaks of production and consumption.

The rallies in electricity prices in the evenings are getting passed on to consumers, so using air conditioners gets more expensive upon sunset. It is a business case for clean flexibility solutions. Due to a high supply of solar electricity during the day, and a cooling-related demand peak in the late afternoon hours, the daily electricity price spreads skyrocketed.

The spread in Poland in the day-ahead segment almost reached EUR 500 per MWh on July 1. Namely, the daily low was EUR 21.04 per MWh below zero, and the peak amounted to EUR 471 per MWh. In Germany, the benchmark went from EUR 0.16 per MWh in negative territory to EUR 404.91 per MWh.

Storage assets charge at low prices and discharge during peak time, reducing the need for costly imported fossil fuels in the evening, and supporting the balancing of the grid, the analysts underscored.

Interconnection played a role as well. The heatwave peaked in different countries on different days, so interconnectors moved electricity to where it was needed most, dissipating the price peaks in the process.

IHA: Turkey’s 2024 hydropower additions highest in Europe again

The world’s hydroelectric capacity increased 1.7% last year to 1.44 TW, the International Hydropower Association said in its annual report. It highlighted the sharp rise in the pumped storage hydropower segment. Turkey doesn’t host any such energy storage facilities, but the country’s additions of conventional capacity were the highest in Europe for the second time in a row.

Hydropower generation rallied 10% to 4.58 PWh in 2024. It rebounded strongly from drought-affected lows the previous year, the International Hydropower Association (IHA) calculated. Data from its 2025 World Hydropower Outlook points to strong global momentum, led by a surge in pumped storage hydropower.

The world’s largest source of renewable electricity accounted for 14.3% of supply.

Scandinavia and Central Asia may see a 5%-15% rise in hydropower output from their current fleet, while Southern Europe, North Africa and the Middle East could experience declines of up to 40% by the century’s end, the authors warned. The declines are driven by longer dry periods, reduced flows and greater evaporation. IHA expects the strongest impact in countries such as Spain, Italy and Turkey.

Notably, the last of the three achieved the highest growth in Europe in overall capacity last year, for the second time in a row. Turkey added 241 MW, making it 11th in the world, after 399 MW the year before. Then it was three notches higher on a global scale.

More than half of capacity in project pipeline is for pumped storage

Hydropower development pipeline grew 8% to 1.08 TW, including 600 GW of pumped storage.

Growth in global capacity amounted to 24.6 GW, against 22 GW in 2023. In relative terms, it rose 1.7% to 1.44 TW, of which pumped storage jumped 5% or 8.4 GW to 189 GW. The rise was 6.5 GW in the previous year. The rate in the pumped storage segment doubled in the past two years.

China continues to dominate, with 14.4 GW of capacity added in 2024, including 7.75 GW of pumped storage. It translates to shares of 59% and a head-spinning 92%, respectively, on the global scale. China reached 436 GW, which was 30.2% of the world total.

Hydropower plants in Norway generated almost two times more electricity than the ones in Turkey

The country has more than 91 GW of pumped storage capacity under construction, compared to over 105 GW in the whole world! China is planning to add a whopping 136 GW beyond that in the segment.

The overall hydropower sector faces a potential shortfall of 60 GW to 70 GW by 2030 from the International Renewable Energy Agency’s (IRENA) target in its “tripling renewables” scenario.

A clear business case for pumped storage in Europe is emerging, supported by a project pipeline of 52.9 GW in development, of which 3 GW is under construction, the report reads.

Turkey has strongest conventional hydroelectric fleet in Europe but poor utilization rate

Norway has the most hydropower capacity in Europe, as it reached 33.9 GW last year. Pumped storage hydropower had a share of 1.4 GW.

Turkey remained second in Europe in overall hydropower capacity and ninth in the world, at 32.77 GW. But there are no pumped storage hydroelectric units in the country, so in conventional terms it ranks the highest on the continent.

On the other hand, hydropower production in Norway was almost two times higher than in Turkey in 2024, 140 TWh versus 75 TWh. The latter increased its output from 66 TWh.

Interestingly, while IHA measured an increase of 241 MW in capacity last year in Turkey, IRENA’s earlier annual report showed growth of 424 MW, to 32.39 GW. There is nearly 600 MW currently under construction in the country, according to the update. It compares to 460 MW in the report released a year ago.

France is Europe’s third, with 25.45 GW at the end of 2024, of which 5.1 GW was pumped storage. Output was equivalent to Turkey’s.

Spain was next overall, at 22.75 GW. Portugal came in second-best in added capacity, at 160 MW. Germany is at the top of the chart in operational pumped storage hydropower – 9.45 GW.

As for the other markets that Balkan Green Energy News tracks, Greece had more than 3 GW of pumped storage projects in development at the end of 2024.

Serbia’s EMS starts construction of third section of Trans-Balkan Corridor

The foundation stone was laid today in Serbia for the third section of the Trans-Balkan Electricity Corridor. The investment amounts to EUR 100 million. It entails a high-voltage overhead power line of 109 kilometers between Obrenovac and Bajina Bašta, equipping two new switchyards in the Obrenovac transformer substation and upgrading the Bajina Bašta substation to 400 kV. The fourth and last section, with the interconnections with Bosnia and Herzegovina and Montenegro, is planned to be completed in 2028.

Serbian Minister of Mining and Energy Dubravka Đedović Handanović said at the groundbreaking ceremony for the third section of the Trans-Balkan Corridor that it is the most important project for the transmission system not only in the country but in Southeastern Europe.

“What highways are for transportation, high-voltage power lines are for energy, and today we are beginning the works on the new part of the most important energy highway,” she said in Obrenovac and added that the segment would enhance the security of supply for consumers in western Serbia.

The third section of the Trans-Balkan Electricity Corridor involves the construction of an overhead power line of 109 kilometers on 309 towers, equipping two new switchyards in the Obrenovac substation and lifting the voltage level in the Bajina Bašta substation to 400 kV.

The project is financed with a EUR 64.5 million loan from Germany’s KfW Development Bank, a grant from the European Union via its Western Balkans Investment Framework (WBIF) of approximately EUR 21 million, and own funds of the Serbian transmission system operator Elektromreža Srbije (EMS), according to the state-owned company’s announcement. The third section is worth EUR 100 million, of which EUR 71 million is for the overhead power line.

“With the completion of the entire project, we will additionally strengthen the links with Bosnia and Herzegovina and Montenegro and beyond, with Italy,” Đedović Handanović stated.

She recalled that significant transmission grid investments are planned in the next five years, including the construction of the Pannonian Corridor toward neighboring Hungary. The priority projects in the segment are worth EUR 500 million in total, the minister revealed.

“I expect the contractors not to be late with the works, so that the project is completed within two and a half years, as it is planned,” Đedović Handanović stressed.

Matejić: Final section to be finished in 2028

General Manager of EMS Jelena Matejić said the construction of the entire Trans-Balkan Corridor is worth more than EUR 200 million. She noted that it includes 323 kilometers of 400 kV power lines, voltage level upgrades for two transformer stations and switchyards in three of them.

The investments in the Trans-Balkan Corridor are estimated at more than EUR 200 million altogether

“Except this section, the third one, we will also have the fourth, for which the funds have been secured, and it will be finished in 2028,” Matejević asserted.

The old lines in western Serbia of 220 kV will be replaced with new, 400 kV systems, which will create possibilities for connecting the planned Bistrica pumped storage hydropower plant to the grid, according to EMS. The contractor is Kodar Energomontaža, and the works are expected to be completed by 2027.

EU donated EUR 38.3 million for Trans-Balkan Electricity Corridor

Head of the EU Delegation in Serbia Emanuele Giaufret pointed out that the funds the EU has earmarked for the current section are part of wider support.

“The EU has secured a EUR 38.3 million donation for the whole Trans-Balkan Corridor, together with KfW’s favorable loans. Over the years, the EU has earmarked more than EUR 1 billion for the energy sector in Serbia. This project is important for the rest of Europe as well, because it will contribute to the creation of a wider, integrated system, which will enable a more stable supply to consumers on the entire continent, as well as to avoid problems in the future,” he stated, as quoted by EMS.

The first section of the Trans-Balkan Corridor, from the city of Pančevo near Belgrade to the Romanian border, was finished in 2017. The second one, between Kragujevac and Kraljevo in central Serbia, is operational since 2022. It included substation upgrades in the two cities. The fourth section needs to connect Bajina Bašta with nearby Višegrad in Bosnia and Herzegovina, and with Pljevlja in Montenegro.

PV plant built next to Slovenia’s only pumped storage hydropower plant Avče

Slovenian company Soške elektrarne Nova Gorica (SENG) commissioned its first solar power plant – Kanalski Vrh. The facility is at its Avče pumped storage hydropower plant, the only one in the country.

Surfaces around large infrastructure such as railways are convenient for photovoltaics as there are very few options for the utilization of such sites. Existing power plants, including hydropower plant reservoirs, are even better locations, as they provide access to strong grid connections and transformers.

With its strict environmental and social regulations and standards, Slovenia is struggling to determine suitable locations for wind turbines, but also larger ground-mounted solar power plants. But state-owned power utility Soške elektrarne Nova Gorica (SENG) managed to fit a photovoltaic system on the banks of the upper reservoir of its Avče pumped storage hydropower plant, in cooperation with the local community.

Kanalski Vrh solar power plant hooked to existing power line

The 2.9 MW solar power plant north of the village of Kanalski Vrh is connected to an existing 20 kV power line. The hydropower operator estimated the annual output at 3.3 GWh. It plans to expand the PV facility to 8 MW by the end of next year.

The first phase was worth EUR 2.2 million. The firm, part of Holding Slovenske elektrarne – HSE Group, used its own funds and won government subsidies.

Area gets natural science park, cycling paths together with PV facility

In the local spatial planning process, Kanalski Vrh got a natural science park and walking and cycling paths. SENG’s first solar power plant spans two hectares and consists of 4,736 modules.

“We have witnessed increasing opposition to the construction of new energy facilities for the production of electricity from renewable sources, but the Kanalski Vrh solar power plant is proof that projects can be successfully completed in an open and transparent dialogue with the local community,” Managing Director of HSE Tomaž Štokelj said.

Avče is the only pumped storage hydroelectric plant in Slovenia. It has 180 MW in pumping mode and 185 MW for production. Avče and four out of five SENG’s hydropower plants on the Soča river are in the municipality of Kanal ob Soči. The first one, Doblar 1, was built in 1939.

Kanal ob Soči is at Slovenia’s western border, with Italy. The firm also operates a group of small hydropower plants.

If the operation of a solar power plant is integrated with a hydroelectric facility, as a hybrid power plant, it can help save water on sunny days.

Slovenia hosts two other PV facilities next to hydropower plants: Brežice and Zlatoličje-Formin.

BESS factory of 1.5 GWh per year opening near Sofia in Bulgaria

International Power Supply (IPS), a Bulgarian manufacturer of battery energy storage systems, is about to launch operations at its new facility near Sofia. Its latest model has 8.2 MWh and fits into a standard container. The company plans to double the factory’s annual capacity to 3 GWh already by the end of the year.

IPS, headquartered in Sofia, is automating and scaling its production of battery energy storage systems (BESS). It is counting on growing demand in Europe, including the domestic market. The company already has orders for 7 GWh for the next three years, Chief Executive Officer Alexander Rangelov told the Kapital news website.

The systems in the new X-BESS line have 8.2 MWh in capacity, fitting into a standard TEU container of 20 feet (6.1 meters). Each consists of seven liquid-cooled modules of 1.17 MWh. The model has inverters of 4 MW, translating to a two-hour duration.

Serial production is about to begin in the Hemus high-tech industrial park near Bulgaria’s capital city. Initially, the annual capacity would be 1.5 GWh, but IPS aims to double it already by the end of the year.

IPS plans another, fully robotic factory

X-BESS started three years ago with a 6.5 MWh version. IPS is currently fulfilling contracts for 670 MWh for projects funded through the country’s National Recovery and Resilience Plan (NRRP or, in Bulgarian, PVU). The company also applied for EUR 150 million from the European Union’s Innovation Fund, for a fully robotic 5 GWh factory.

The majority owner of IPS, with 65.5%, is Power Technology Investment Group. It is controlled by the family of the founder Stoil Rangelov Trifonov. SIL Energy Invest has 31.5%. The Capital Investments Fund (CIFund) of the Bulgarian Development Bank holds the remaining 3%.

X-BESS includes a battery management system developed by IPS

The company mainly uses European parts and the lithium-iron-phosphate (LFP) battery cells are from China. The battery management system (BMS) is proprietary. The project pipeline includes a 5 MW rooftop solar power plant for the new factory, combined with own batteries.

IPS is looking for a strategic partner for further expansion.

Just ten days ago, a BESS facility of 124.1 MW – 496.4 MWh was inaugurated in Lovech in Bulgaria. The Ministry of Energy said it is the biggest in the European Union.

Deal with NEK for BESS at Vacha 1 hydroelectric plant

In consortium with GBS Energy Solutions, IPS recently won a tender for equipping the Vacha 1 hydropower plant with BESS. It is a pilot project of state-owned National Electricity Co. (NEK), which has several such investments underway.

The deal is for a system of at least 5 MW in capability and 10 MWh in capacity. The minimum round-trip efficiency is 85%. At 365 cycles per year, the contractors guarantee at least 60 GWh within the duration the 15-year arrangement. They won the job, which includes maintenance, with a bid of EUR 3.4 million.

NEK is also planning another pumped storage hydropower plant at the Vacha dam

Notably, Minister of Energy Zhecho Stankov said last week that NEK sent applications to the European Commission for four pumped storage hydropower projects. Initially, two facilities were planned, at the Batak and Dospat sites. Stankov revealed there would be two systems at Dospat.

The fourth new pumped storage hydroelectric plant is planned near Ravnogor, he said. The village is right next to Vacha 1 and the existing Orphey pumped storage system. The proposed facility would have some 800 MW in capacity, similar to Chaira, according to Stankov. The three existing pumped storage hydropower plants and the sites for the four projects are all in the Rhodope mountains in the south.

North Macedonia in talks on project to build two hydropower plants

North Macedonia is negotiating a strategic project to build two hydropower plants, Čebren and Galište, in an investment estimated at EUR 1.2 to 1.3 billion, according to Prime Minister Hristijan Mickoski. A tender for building the Čebren pumped storage hydropower plant was annulled by the previous government in early 2024.

The country intends to finance the construction of the two hydropower plants with a loan from the United Kingdom, the prime minister said. He indicated that funding has been secured for several government projects, partly through loans and partly through private investments, according to a statement by the Government of North Macedonia.

The Čebren and Galište project could be financed from a British loan

In the previous tender, the Čebren hydroelectric project was planned to have a capacity of 333 MW, with an option for another unit and 458 MW in total.

In early 2024, the former government annulled the tender, in which Greece-based Public Power Corp. (PPC) and Archirodon were selected for the Čebren project. The authorities said at the time that they would analyze whether it would be more profitable to build Čebren with the state’s own funds or with the help of strategic investors.

A few months ago, Minister of Energy, Mining and Minerals Sanja Božinovska said projects were under development for battery energy storage systems (BESS) and pumped storage hydropower plants.

The project will last several decades, Mickoski says

Addressing the parliament today, Mickoski described the project as strategic, adding that it would not be completed during this government’s term of office. “This is a project that will last several decades,” he said. The funding will be provided through low-interest loans as a state investment, and the rest under market terms and through direct private investment, according to Mickoski.

The prime minister is also confident that the two proposed reservoirs could provide additional water for irrigation amid future climate change impacts and help boost tourism development in the area.
