Water shortages in Southeastern Europe point to desalination as strategic approach

Former Minister of Environment and Water of Bulgaria Borislav Sandov is urging the country’s authorities to deploy alternative water supply solutions, including desalination, to counter shortages. Greece is preparing a radical change in its water management model. Turkey got its first floating seawater purification platform, running on solar and wind power.

Southeastern Europe is among the most jeopardized regions in the world in the context of global warming. The lack of water has the most drastic effect on everything from wildlife to food production, energy and public health. Bulgaria’s former Minister of Environment and Water Borislav Sandov warned that over half a million people in the country are at risk of water shortages.

Eastern and northeastern Bulgaria have a persistent issue with droughts and lack of water, necessitating a switch toward alternative forms of supply in the next five to 10 years, including seawater desalination plants, he recently told bTV.

In addition to climatic factors, there are serious shortcomings in water management, together with theft and corruption, Sandov claimed. He pointed to an example where drastically undersized pipes of poor quality were installed in one area, resulting in constant breakdowns and supply interruptions.

Sandov attributed some of the water stress to fragmented management between different local, regional and national institutions. In his words, as much as 10% of all settlements in Bulgaria, though mostly small ones, aren’t covered by waterworks and sewerage systems. Moreover, 44% of the water in the network isn’t measured in volume terms at the entry point and 50% of the water sources don’t have a valid permit from the competent authority, he added.

Notably, a quarter of the population in neighboring Serbia occasionally or permanently lacks safe drinking water from waterworks systems.

Greece to radically change its water management system

Greece decided to get ahead of the droughts and heatwaves. The government has promised radical change in water management: a more functional system with more investments and new technologies, including desalination, but also recycling.

Tourism in the summer months exacerbates the water stress. On some islands, demand surges by up to 30 times. It creates conflict with the needs for irrigation for food production. Greek islands mostly use underground aquifers with easily exhaustible capacity.

Rainfall and snowfall in the country are gradually decreasing.

Similar to Bulgaria, water management is spread across hundreds of operators and institutions, lacking coordination. Losses in drinking water supply amount to as much as 40%, in comparison with up to a staggering 60% in irrigation.

The government in Athens promised water would remain a public good

According to a study by Deloitte with data from 2022, more than EUR 10 billion is necessary for investments in the two segments, excluding Attica. It is where Athens is located. Another EUR 500 million to EUR 700 million is needed for the peninsula.

Government-controlled power utility Public Power Corp. (PPC) will reportedly enter the game, not least because municipal water and sewerage firms owe it more than EUR 400 million. The company would convert debts into minority stakes in three centralized entities: for the regions of Athens and Thessaloniki and the rest of the country, the media learned.

PPC can contribute with its knowhow and experience in the construction and operation of dams and hydropower plants.

Importantly, the government vowed to keep water a public good.

Floating desalination platform with hybrid power plant put into operation in western Turkey

Right opposite the Greek island of Kos, offshore Bitez Marina, the Bodrum Municipality inaugurated Turkey’s first floating seawater purification platform. It runs entirely on renewable energy, producing 20 cubic metres of clean, non-potable water every day.

The project was developed in partnership with Istanbul-based company Blue Hybrid Solutions. The facility is powered by solar panels and two small wind turbines. It delivers water to an onshore tank for irrigation, emergency needs and, when required, public consumption, the local authority said.

Greece is already conducting a massive project for energy independence of numerous non-interconnected islands, including investments in desalination powered by renewables. It is also working to link other islands to the mainland grid.

EDP Renewables sells wind farms in Greece to Enel-Macquarie joint venture

Principia agreed to acquire all four EDPR’s wind power plants in Greece. The joint venture of Enel and Macquarie Asset Management’s funds is nearing 800 MW in renewable energy and battery storage capacity in the country.

Principia, owned equally by Italy-based Enel and funds managed by Macquarie Asset Management, headquartered in Australia, is strengthening its presence in Greece with a purchase of four wind farms. EDP Renewables is selling the facilities to the firm after reportedly deciding to exit the country.

The joint venture, which expects to close the transaction later this year, revealed that the estimated enterprise value exceeds EUR 200 million. The measure can include debt and some other items. The takeover is adding 149.6 MW to its operational capacity, which would reach 727 MW, from 70 power plants. Wind power accounts for 517.8 MW.

With the purchase, Principia will operate a total of 517.8 MW in wind power capacity.

“The acquisition of this portfolio strategically strengthens Principia’s presence in the Greek renewable energy market, in a constantly evolving environment, and reaffirms a role of leadership in the country’s energy transition. With this investment, we further reinforce our position in the Greek clean energy market and take another step toward delivering on our ambitious plan for growth, diversification, and reliable clean energy generation across Greece,” Principia’s Chief Executive Officer Aristotelis Chantavas said.

All four wind farms operate within CfD scheme

All four wind farms are operating under 20-year contracts for difference (CfDs). Livadi (45 MW) and Erimia (35 MW) are in Malesina, Phthiotis. Wind power plants Xironomi (36 MW) and Chalcodonio (33.6 MW) were commissioned this year. They are located in Boeotia, Central Greece, and Magnesia, Thessaly, respectively.

Newmoney learned, without revealing its source, that Terna Energy, ENI Plenitude, HELLENiQ Energy and some investment funds also participated in the process, interested in the portfolio. The acquisition will lift Principia by one notch to become third among the largest wind farm operators in the country, the article adds.

Principia aims to complete construction of 49 MW battery system by year-end

Principia has another 230 MW under construction or in the ready-to-build stage, and 5.6 GW more in various stages of development.

It is building a battery energy storage system (BESS) of 49 MW in Polygyros, in the Halkidiki peninsula. It won government support at Greece’s second energy storage auction.

The Paleolivada facility is due to come online before the end of the year. Construction began in March. It will have 98 MWh in guaranteed capacity, versus 127 MWh installed.

The firm has a mature project for a hybrid power plant of 111 MW and 70 MW of solar power capacity. The site is in Atherinolakos, in Sitia in the south of Crete.

Principia inaugurated a photovoltaic cluster of 95 MW in May. The Perasma facility, near the villages of Mavrodendri and Sidera, is set to generate 126.8 MW per year. It comprises seven units and 170,000 bifacial panels.

Macquarie Asset Management agreed to buy 50% of Enel Green Power Hellas in 2023.

Of note, EDP Renewables (EDPR) is headquartered in Spain, but traded on the Euronext Lisbon stock exchange. It is a subsidiary of EDP.

Production starts at new 38.4 MW wind farm northeast of Bucharest

Eximprod, which installed the first wind turbine in Romania more than two decades ago, delivered the first megawatt-hours to the grid from its new wind farm in the country’s east. In addition, it is about to receive a commercial operating license for a 49.5 MW solar park in Prahova county.

Several other wind parks are also under construction amid a revival in investments in Romania. Rezolv recently secured financing for phase 2 of its Vifor wind power plant, set to become one of the largest in Europe.

Romania has been enjoying a solar power boom for the past three years, and the pace of the construction of battery energy storage facilities (BESS) is accelerating. On the wind energy front, the country’s capacity has barely held above 3 GW for a long time after the 3.24 GW peak in 2014, due to the failure of an incentives mechanism. But the investment momentum is strengthening – notably, Eximprod said it launched the operation of its 38.4 MW wind power plant in the Galați area.

The company actually installed the first wind turbine in Romania. In 2003, it put online the Vestas V 47 machine of 660 kW in Topolog in Tulcea County in the country’s east.

Eximprod Group (EPG) also provides equipment and services in the energy sector. The company’s contractor Lemacons poured concrete less than half a year ago for the foundation of the first wind turbine in the new Cudalbi 2 facility. It is located in Galați county in eastern Romania, in the Western Moldavia region.

Eximprod received support through National Recovery and Resilience Plan

Cudalbi 2 is the first wind park in the country with Enercon turbines in 12 years. The model is E-160 EP5 E2, of 5.5 MW. Eximprod has won state support for the project northeast of Bucharest via the National Recovery and Resilience Plan (NRRP or, in Romanian, PNRR). The funds are approved under the European Union’s Recovery and Resilience Facility (RRF).

The company has also built the nearby Cudalbi 1 wind farm of 54 MW, consisting of nine turbines.

In addition, Eximprod is about to receive the commercial operating license from National Energy Regulatory Authority (ANRE) for its Solar System Project photovoltaic plant. It completed the facility with 49.5 MW in connection capacity in April. According to its documentation, the facility has 65 MW in peak capacity. It consists of five units with grid connections of 9.9 MW each.

The solar park is in Ciorani, Prahova county, north of the capital city. The endeavor was reportedly worth EUR 56.2 million including a grant of EUR 13.4 million from the NRRP. The company plans to add a BESS unit of 21 MW in operating power. The said final permit will allow the project firm to sell electricity.

Lenders indicate confidence in Romania’s wind power market with financing package for Vifor

In other recent news, Rezolv secured a EUR 331 million financing package for the 269 MW second phase of its Vifor wind farm in Buzău county. It includes EUR 44 million from the European Bank for Reconstruction and Development (EBRD).

Erste Group, UniCredit Group, International Finance Corp. (IFC), Intesa Sanpaolo Group, OTP Bank and Raiffeisenlandesbank Niederösterreich-Wien all participate in the arrangement.

The Vifor wind park would consist of 72 turbines of 6.4 MW each

The first part of Vifor is under construction and scheduled for commissioning in the spring. Rezolv plans to complete phase two in late 2027.  The wind park would be one of the biggest in Europe, at 461 MW. The company is installing 72 Vestas V162 turbines of 6.4 MW.

Rezolv won a contract-for-difference (CfD) at the country’s first renewable energy auctions for phase 2, for 240 MW. The government approved 1.1 GW for wind power. The qualifications phase is ongoing for the second round of auctions, for 2 GW for wind park projects and 1.47 GW for photovoltaics.

Several wind farms under construction

According to the International Renewable Energy Agency (IRENA), Romania had just under 3.1 GW in wind power capacity in operation at the end of 2024.

Eurowind Energy built the turbines earlier this year at its Pecineaga wind park. Greece-based Public Power Corp. (PPC) is supposed to connect its Deleni facility to the grid before the end of the year.

OX2 is building the Green Breeze wind farm as the turnkey contractor for the investor, Nala Renewables.

IRENA: 91% of new renewables units are more cost-effective than fossil fuel alternatives

The fossil fuel age is crumbling, according to UN Secretary-General António Guterres. Renewables maintained their cost leadership in global power markets, the International Renewable Energy Agency said in an annual report. In 2024, onshore wind farms were the cheapest of all versus the lowest-cost fossil fuel alternatives, by 53% on average, while photovoltaic systems were 41% cheaper.

Onshore wind power was also the cheapest in levelized cost of electricity (LCOE) terms, followed by solar power. At the same time, 91% of newly commissioned utility-scale capacity was delivering power at a cost lower than for the cheapest electricity from new fossil fuel–fired units.

The Renewable Power Generation Costs in 2024 report confirmed the price advantage of renewables over fossil fuels, with cost declines driven by technological innovation, competitive supply chains and economies of scale, the International Renewable Energy Agency said. IRENA expects cost reductions to continue, but highlighted the short-term challenges.

Geopolitical shifts including trade tariffs, raw material bottlenecks, and evolving manufacturing dynamics, particularly in China, could temporarily raise costs.

Asia, Africa and South America, with stronger learning rates and high renewable potential, could see pronounced cost declines.

Higher costs are likely to persist in Europe and North America, driven by structural challenges such as permitting delays, limited grid capacity, and higher balance-of-system expenses, according to the update. In contrast, regions like Asia, Africa and South America, with stronger learning rates and high renewable potential, could see pronounced cost declines.

The organization pointed to the need for stable and predictable revenue frameworks to lower investment risk and attract capital.

“Clean energy is smart economics – and the world is following the money,” United Nations Secretary-General António Guterres stressed. In his view, the fossil fuel age is crumbling.

Capital costs inflating LCOE in developing countries

Mitigating financing risk is central to scaling renewables in both mature and emerging markets. Instruments such as power purchase agreements (PPAs) play a pivotal role in accessing affordable finance, while inconsistent policy environments and opaque procurement processes undermine investor confidence, IRENA added.

In many developing countries of the Global South, high capital costs, influenced by macroeconomic conditions and perceived investment risks, significantly inflate the levelized cost of electricity (LCOE) of renewables.

Onshore wind power production cheapest by far of all kinds of electricity

In 2024, onshore wind farms were the cheapest of all versus the lowest-cost fossil fuel alternatives, by 53% on average, while photovoltaic facilities were 41% cheaper. Of note, the cost of battery energy storage systems (BESS) declined by 93% from 2010 to 2024, to USD 192 per kWh.

Onshore wind remained the most affordable source of new renewable electricity, with a global weighted average LCOE at USD 0.034 per kWh (USD 34 per MWh), followed by new solar, at USD 0.043 per kWh, and new hydropower plants, USD 0.057 per kWh.

Again per the levelized cost of electricity, 91% of newly commissioned utility-scale renewables capacity was delivering power at a lower cost than the most affordable new fossil fuel–based units.

That said, LCOE increased slightly for solar power, by 0.6%. Onshore wind power was 3% more expensive than in 2023, compared to 4% for offshore wind and 13% for the bioenergy segment. Meanwhile, costs declined for concentrated solar power (CSP), by 46%, followed by electricity from geothermal units, 16%, and hydropower, which slipped 2%.

Solar and wind energy prices have begun to stabilize, which is a natural sign of market maturity, the authors underscored.

Clear path to affordable, secure, sustainable energy

The addition of 582 GW of renewables capacity in 2024 led to significant cost savings, avoiding fossil fuel use valued at about USD 57 billion, new data shows. Looking at all renewables in operation, the avoided fossil fuel costs in 2024 reached up to USD 467 billion, IRENA’s Director-General Francesco La Camera stated.

New renewable power outcompetes fossil fuels on cost, offering a clear path to affordable, secure and sustainable energy, he pointed out.

Pexapark: PPA activity in Europe drops in first half of 2025

The number of power purchase agreements (PPAs) for renewables in Europe fell by 31% and the volume tumbled 26% in the first half of the year from the levels in the same period of 2024, Pexapark found. Germany and France registered sharp declines in the photovoltaics segment, but a surge in Italy and Spain has more than offset the drop.

The meteoric rise in deals for battery energy storage systems, BESS, is a clear sign of its maturity.

In its latest report, analytics and advisory firm Pexapark provided a detailed look into PPAs and contracts for battery energy storage systems in the first six months of 2025. It found that PPA activity shrank by more than a quarter in year-over-year terms, but not everywhere and not due to solar power.

Across 124 deals, 6.08 GW of renewable electricity capacity was contracted in the first half, which is 31% and 26% down, respectively, from the same period of 2024. Conversely, the average deal size advanced 5% to 48.2 MW.

Notably, the April-June period was much weaker than the first quarter of the year, with just 50 deals, but the volumes were almost evenly split.

The main technologies in the first half were solar power, 4.2 GW from 73 deals, onshore wind (1.4 GW and 32 PPAs), mixed technology (290 MW and nine deals) and offshore wind (134 MW and four deals). The result is proportionate to the picture from January through June 2024.

Despite concerns over saturation of demand for standalone solar, volumes have firmed. The 4.2 GW of solar capacity contracted under PPAs compares to 3.9 GW of the first half of last year. The deal count landed at 73, against 95, which is in line with the overall trend.

PPA activity in Germany plunged 84% in terms of volume

Solar offtake activity reveals a clear split in market momentum. It is slowing down in markets where cannibalization has worsened drastically and rapidly – such as Germany and France. In fact, Germany saw the largest decline in volumes – a remarkable 84% year-on-year decrease in terms of overall volumes, with 228 MW across eight deals in the last six months, versus 1.2 GW and 31 deals in last year’s equivalent.

There is stable or even upward appetite in markets which have had time to adjust to cannibalization and the lower valuation of solar production, or where cannibalization levels are still very low

Conversely, solar PPA activity in Italy and Spain spiked, more than making up for the said decline.

“These numbers support the hypothesis that there is stable, or even upward appetite in markets which have had time to adjust to cannibalization and the lower valuation of solar production – i.e., Spain, or cannibalization levels are still very low – such as Italy. Italy’s solar PPA volumes grew 184% year-on-year, with nearly an additional 700 MW procured compared to the same period last year. Corporate appetite in the country is growing, and so is deal size – with a 420 MW solar corporate deal announced in June comprising the country’s largest PPA ever recorded,” the analysis reads.

As for Southeastern Europe, OMV Petrom’s deal with Enery for their joint solar power project Gabare in Bulgaria was Europe’ third-largest PPA in June.

Flexibility monetization is opportunity for market players with right profile

In a market increasingly driven by flexibility monetization, today’s challenges – cannibalization, future capture dynamics and balancing risks – are becoming opportunities for market players with the right profile. And with corporate buyers more hesitant to pay premiums for solar, transactable prices are—perhaps for the first time in a while – closer to perceived fair value, according to the report’s authors.

Wholesale electricity prices in Sweden were negative for almost two fifths of the time in the first six months of 2025

Hourly periods with negative prices at wholesale electricity markets continued strong in the first half. Sweden maintained its top position by far, with most such events. There were 1,635 hours with negative prices from January until the end of June. It is a stunning 37.8% share of the entire period and already 63% of the tally from all last year.

The other jurisdictions that make up the top five in Europe: Finland, Germany, the Netherlands and Belgium, remained the same since 2024.

On average, European countries have already reached around 67% of the number of hours counted in 2024 as a whole. Norway hit 90%, Denmark 87% and Spain climbed to 86%, suggesting that last year’s records would fall.

Top five European markets by number of negative price hours, 2024 vs. the first half of 2025

BESS deal volumes already three times higher than in all 2024

The maturity of the BESS industry is clearly reflected in the deal count and contracted volumes over the past 18 months, with the trend increasingly pronounced in 2025.

Battery storage capacity being contracted under optimization or fixed-revenue offtake contracts (so-called floors and tolls, respectively) amounted to a total of 4.6 GW in capability and 9.2 GWh in capacity across 36 deals. It is just over three times more than in entire 2024 in both benchmarks. The deal count was 44% up from all last year.

The lion’s share of the deal count concerns BESS assets with a two-hour duration

The rapid growth was driven by a wave of new agreements in the two most advanced markets – Great Britain and Germany – alongside first-ever BESS deals emerging in Belgium, Poland, Greece, and Bulgaria. The lion’s share of the deal count concerns BESS assets with a two-hour duration, which the ratio of operating power and capacity also indicates.

Slovenia publishes call for incentives for wind, solar power projects

Solar and wind power projects with or without energy storage that are on Slovenia’s priority list can be submitted for grants from the European Union’s Modernisation Fund. The round is worth EUR 29.5 million and the deadline is January 7. Notably, of the 1,117 projects for renewables and cogeneration approved for state support so far, only 254 were completed by the end of 2024.

The Ministry of the Environment, Climate and Energy launched a public call for cofunding under a mechanism for the modernization of energy systems in Slovenia and improvement of energy efficiency. It is for projects for solar and wind power plants, with or without storage, from the so-called A list of indicative, priority investments.

Eligible companies can receive support from the EU’s Modernisation Fund under the RES Scheme (Part A). It was approved by the European Investment Bank. The list was published in March of last year.

Total planned support amounts to over EUR 84 million and the selected projects must be completed by the end of September 2030. The deadline for submissions in the current round is January 7, 2026.

The grants can cover up to 45% of the costs for photovoltaic and wind power systems and a maximum of 30% of the electricity storage segment, the documentation shows. Storage capacity must be at least 0.75 kWh per kW of the nominal capacity of the power plant.

All five eligible projects are within state-owned HSE Group

There are 21 items on the A list and most are power grid investments. Only five are for renewables, of which Dravske elektrarne Maribor (DEM) is present with its controversial Ojstrica wind farm project, the proposed expansion of the Zlatoličje-Formin solar park, and the ZOOP photovoltaic project for 9.9 MW in peak capacity on the former Pobrežje waste landfill.

The largest priority investment among the ones that can apply in the current round is HSE’s proposed floating PV plant with batteries

The company is part of state-owned Holding Slovenske elektrarne – HSE. Another subsidiary on the list, Soške elektrarne Nova Gorica (SENG), intends to expand its recently commissioned Kanalski Vrh solar power plant.

HSE itself has the largest project – for the Družmirje floating solar power plant, which would include storage. It also plans to produce green hydrogen using electricity from the facility.

Few completed energy production projects among ones selected through public calls

The Energy Agency of Slovenia has so far approved 1,117 renewables and cogeneration projects to enter the support scheme, selected through 13 public calls. The combined planned capacity is 794 MW, of which there were 996 renewable energy projects, for 682 MW.

However, only 254 endeavors, with 112.6 MW altogether, were completed by the end of last year. In the previous round, the agency selected 507 projects, for a total nominal capacity of just over 259 MW, mostly for PV plants.

Of note, lengthy procedures, strict environmental rules and local opposition are keeping Slovenia at the bottom of the European Union’s wind power capacity chart in the European Union. The country hosts just three standalone wind turbines and DEM has contracted the fourth one.

Electrica sells green bonds for EUR 500 million amid record demand

Electricity supplier and distributor Electrica listed its first green bonds on the Luxembourg Stock Exchange. It was the largest issuance of its kind among Romanian companies, excluding financials.

Electrica, in which the Romanian Government controls a stake of just under 50%, issued green bonds worth up to EUR 500 million. It is using the proceeds to finance and refinance its projects, mainly for green energy production and energy storage.

The senior unsecured green bonds, maturing in five years, are now listed on the Luxembourg Stock Exchange. Admission to trading on the Bucharest Stock Exchange is estimated to take place at the beginning of August, Electrica said.

The company’s core activities are electricity distribution and supply and energy services, but it is expanding into renewables and battery storage.

Pricing reaches 2.3 percentage points above benchmark rate

Credit appraisal agency Fitch has assigned the 4.375% senior unsecured green notes a BBB- rating. It is the lowest investment grade. The projects will have a limited connection to Electrica’s 100%-owned distribution and supply subsidiaries Distribuție Energie Electrică Romania (DEER) and Electrica Furnizare, the note adds.

Electrica targets 1 GW of installed renewable energy capacity by 2030 alongside the deployment of 900 MWh of energy storage

The company’s inaugural debt securities were priced at a yield of 4.566%, according to a regulatory filing. It was 2.3 percentage points above the benchmark mid-interest rate swap. The demand from investors at the final price exceeded the supply by more than 11.5 times, marking a record oversubscription in bond issuances of Romanian companies, Electrica pointed out.

Moreover, it was the largest green bond issuance in Romania excluding financial institutions. Electrica targets 1 GW of installed capacity by 2030 alongside the deployment of 900 MWh of energy storage.

Electrica grows market capitalization by one fifth this year

Banca Comercială Română (member of Erste Group), BNP Paribas, Citi, ING, J.P. Morgan and Raiffeisen Bank International were the joint global coordinators and joint bookrunners in the transaction, while BT Capital Partners, IMI-Intesa Sanpaolo, Société Générale and UniCredit were joint bookrunners.

Electrica has EUR 1.06 billion in market capitalization. Its shares surged 21.1% since the end of last year.

Serbia’s EPS starts trial operation of its Petka PV plant on coal tailings dump

Serbian state-owned power utility Elektroprivreda Srbije, EPS, connected its first larger photovoltaic unit to the grid. The new solar power plant is called Petka and it has a 10 MW grid connection. It is located in the Kostolac coal mining complex east of Belgrade, next to a wind park that is nearing completion. Each new megawatt is important, according to Minister of Mining and Energy Dubravka Đedović Handanović and the company’s Chief Executive Officer Dušan Živković.

After many years of planning and launching numerous solar power projects, EPS launched the trial operation of its first larger facility of the kind. The Petka PV system has 10 MW in connection capacity. It is located on a former tailings dump of the Ćirikovac open pit coal mine in the Kostolac complex.

“It is another important pioneering milestone in our energy sector. We are now producing clean, green energy on the site of an old mining dump, which is a turning point and the beginning of the energy transition of Elektroprivreda Srbije and an example how we can use old energy for new energy,” Minister of Mining and Energy Dubravka Đedović Handanović stated.

Of note, EPS recently installed solar panels of 948 kW total on the buildings within the Termoelektrana Nikola Tesla A (TENT A) coal power plant and of TENT’s rail transportation arm. Another photovoltaic system is on the Lazići dam in Zaovine, belonging to the state-owned utility’s Bajina Bašta hydropower plant.

EPS to connect adjacent wind park Kostolac to grid next month

There are no big or small projects, as every megawatt is important for Serbia’s energy security and it means greater security, Đedović Handanović pointed out.

“In addition to the Petka solar power plant, wind generators of EPS’s first wind park stand tall today in the mining area. They are also built mainly on recultivated tailings dumps. We expect the connection to the grid in August and a testing phase, when the blades will start spinning. That way we will strengthen our electricity system here in Kostolac by 76 MW of green energy,” the minister said.

The ministry’s priorities are the projects for the Bistrica pumped storage hydropower plant and battery-backed solar power plants of 1 GW in total connection capacity

She recalled that the strategic goal of the Government of Serbia is defined by the Energy Development Strategy, to reach a 45% share of renewable energy sources by 2030.

“We have much more to do and put in maximum efforts, because ahead of us are strategic projects which will change Serbia’s electricity bloodflow to a significant extent. They primarily entail the construction of the Bistrica pumped storage hydropower plant and the project for solar power plants of 1 GW with battery storage units. Energy investments necessary in the next ten years are estimated at about EUR 14 billion. Therefore, we must make up for all the delays and be up to the task, to secure energy tranquility for the future generations”, Đedović Handanović added.

EPS continuing with other green projects in its coal mining areas

EPS’s Chief Executive Officer Dušan Živković said each new megawatt is important for the company and the electricity system, especially in tropical days, when electricity demand is getting higher and higher.

“Not only are we strengthening our green portfolio that way, but also the reliability of the entire energy system, while citizens and companies have a secure supply, the same as until now. Projects like this one are concrete steps toward decarbonization and a sustainable energy development, which are also our goals for the decades to come. We will continue with the similar projects both here in Kostolac and also at dumping and landfilling sites in other parts of EPS,” he asserted.

Petka is one of the first PV facilities in the Western Balkans on former coal exploitation locations.

In addition, the construction of the Kostolac B3 coal plant in the same complex was finished last year. It was EPS’s first big energy production system in more than three decades.

Solar beats nuclear in June, becoming EU’s biggest electricity source for first time

Solar became the EU’s largest source of electricity for the first time in June 2025. National records for both photovoltaics and wind rolled in in May and June, pushing coal to an all-time low.

Solar was the largest source of electricity in the European Union for the first time last month, with multiple countries producing record amounts of solar power, Ember found. Wind power achieved the highest ever generation for the months of May and June, the think tank said.

Solar power generated 22.1% of EU electricity (45.4 TWh) in June, more than any other power source. It was a year-over-year increase of 22%. In second place was nuclear, with 21.8% (44.7 TWh), followed by wind, with 15.8% (32.4 TWh).

The big opportunity now comes from adding battery storage and flexibility to extend the use of renewable power into mornings and evenings, where fossil fuels still set high power prices, according to Ember’s Senior Energy analyst Chris Rosslowe.

At least thirteen EU countries set monthly solar records

At least thirteen countries recorded their highest-ever month of solar generation, amid an ongoing surge in photovoltaic installations. Among them were Bulgaria, Croatia, Greece, Slovenia and Romania, all the EU countries in the region that Balkan Green Energy News is focused on except Cyprus, for which there was no data for June.

Wind power reached an all-time high shares of 16.6% (33.7 TWh) and 15.8% (32.4 TWh) in May and June, respectively

Strong photovoltaic output helped the power system to handle higher levels of demand resulting from heatwaves that gripped the continent towards the end of the month, according to the report.

Wind farms generated 16.6% (33.7 TWh) and 15.8% (32.4 TWh) of EU electricity in May and June, respectively. It was an all-time high for both months. Notably, at the start of the year, wind conditions were relatively poor. They improved, and they were the main driver, though capacity has been continuously growing over the past year. Several large offshore wind farms were commissioned.

Coal falls to record low

As a result of high renewables generation in June, coal had the lowest-ever share of EU electricity. Total fossil generation was also low, but it grew in the entire first half of the year on an annual basis.

Coal generated just 6.1% (12.6 TWh) of EU electricity in June, down from the 8.8% registered in the same month of last year.

The two countries that account for the vast majority of EU coal power (79% in June) both saw record lows in June. Namely, Germany generated just 12.4% (4.8 TWh) of its power from coal, and Poland 42.9% (5.1 TWh). Four other countries recorded their lowest-ever month of coal generation in June: Czechia (17.9%), Bulgaria (16.7%), Denmark (3.3%) and Spain (0.6%), which is approaching its coal phaseout.

Fossil fuels generated 23.6% (48.5 TWh) of EU electricity in June, just above the record low of 22.9% in May 2024. Nevertheless, fossil generation in the first half of 2025 was 13% higher (by 45.7 TWh) than in the first half of 2024, mainly due to a jump in gas generation by 19% or 35.5 TWh. Lower hydropower (due to drought) and wind generation than last year, and increasing demand marked the period.

Electricity demand continued on an upward trajectory. In the first half of 2025, the EU consumed 1.31 PWh of electricity or 2.2% more than in the same period of last year.

Cyprus curtails as much renewable electricity in first half of 2025 as whole last year

According to data compiled by the CyprusGrid tracking platform, the island country curtailed more than 167 GWh of renewable electricity in the first six months of 2025. It was equivalent to last year’s entire cuts. On average, two thirds of the potential green energy production was lost per day in March.

In addition to being the only European Union member state without an interconnection with another power system, Cyprus only has oil-fired generators, a surging solar power capacity, wind parks and some biomass-fired facilities. Other countries, like Greece, also must curtail renewable electricity units, but maintaining system stability requires more drastic cuts in the isolated island nation. Notably, it still lacks energy storage, while the conventional power plants lack flexibility.

According to a statistical report from a few months ago, Cyprus hosted almost 850 MW of solar power, of which less than 400 MW was in commercial photovoltaic plants. Prosumers operated the rest. Licensed projects amounted to 2.8 GW. Wind power amounts to 155 MW.

Rapid growth of solar power capacity brings more episodes of overloads, when grid operators have to curtail photovoltaic and wind power production. At the same time, sudden weather changes can push production to a critically low level, which can also cause outages before conventional facilities step in to cover the deficit.

Curtailments to double this year

Founder of the CyprusGrid tracking platform Andreas Procopiou said on LinkedIn that more than 167 GWh of renewable energy was curtailed in the first half of the year. It’s how much was lost whole last year, he pointed out.

The conventional power plants in Cyprus aren’t able to lower or boost production fast enough to balance the changes in renewables

The cuts will almost certainly exceed 300 GWh in 2025, doubling the all-time high in just one year, Procopiou estimated. The average monthly growth rate has actually more than doubled from 2024, according to the developer of the electricity generation tracker.

Cuts boost emission costs by EUR 8 million

Curtailments erased 20.8 GWh in June alone. The daily average was 29.3% of total renewables output. It compares to May’s 33.9 GWh and 50.3%, respectively, after 37.9 GWh and 61.4% in April. March was the worst, with 38.2 GWh lost, or a whopping 67.9% of potential production, CyprusGrid data shows.

“Solar energy that could reduce costs and pollutants ends up being lost. For 2025 alone, the cuts already amount to more than 100,000 tons of additional CO₂ emissions and an additional burden of around EUR 8 million for emission allowances. A cost that we all ultimately pay,” Procopiou stressed.

Without storage, flexibility and serious planning, the energy transition remains just an empty slogan, the renewable energy expert pointed out.

Nevertheless, French giant TotalEnergies isn’t intimidated by the curtailments. It won the environmental approval a month ago for a photovoltaic park of 100 MW in peak capacity. But the company is planning to include energy storage.
