US electricity prices soar 40% in H1 2025, outpacing EU’s 30% increase

In the first half of 2025, wholesale electricity prices in the European Union were about 30% higher than in same period of 2024, while a 40% increase was recorded in the United States. The penetration of negative prices in the EU continues, with their share doubling in H1 2025, according to the latest report of the International Energy Agency.

Wholesale electricity prices in the EU averaged around USD 90 per MWh as costs were mostly underpinned by natural gas prices, which were on average about 20% above the levels from 2024, IEA’s Electricity Mid-Year Update 2025 reads.

Prices saw upward pressure from a boost in fossil-fired generation due to a year-on-year drop in electricity generation from wind and hydropower.

While average power prices remained below the 2023 levels, they were higher than in 2019, according to IEA. The latter is a reference year because it was the last one before turbulences started – the COVID-19 pandemic, energy crisis, and the war in Ukraine.

Electricity prices in the Nordics remained the lowest in Europe

Latest futures prices in the EU average USD 80 per MWh for 2026, indicating a decline of around 15% from 2025, the report underlines.

High gas prices also affected the electricity market in the US, combined with colder weather. Power prices averaged around USD 48 per MWh. However, the increase was from a low base, as prices in the first half of 2024 were the lowest for the first half of the year since 2020, the report notes.

Average electricity prices in the Nordics remained the lowest in Europe, falling by more than 20% year-over-year in the first six months of 2025 to about USD 40 per MWh. It was the result of an increase in wind power generation and higher hydropower output, according to the report.

The update brings details on Germany, France, Japan, India, Australia, and the United Kingdom as well.

Occurence of negative prices doubled

IEA notes that the frequency of negative wholesale prices is increasing in various markets, underscoring the need for greater flexibility in supply and demand. The authors of the report propose appropriate regulatory frameworks and market designs to boost greater demand response and energy storage.

The share of hours with negative prices on the wholesale market reached 8% to 9% in the first half of the year in countries such as Germany, the Netherlands, and Spain – up from between 4% and 5% in 2024, the report reads.

The average price this year in the EU is expected to be twice as high as in the US and about 50% higher than in China

Electricity prices for energy-intensive industries continued to vary significantly across regions. After declining since their 2022 peak, they are expected to rise year-on-year in 2025 in the EU, driven by higher wholesale price levels.

The average price this year in the EU is expected to be twice as high as in the US and about 50% higher than in China, according to IEA projections. By comparison, in 2019, prices in the EU were approximately 50% higher than in the United States and 20% higher than in China.

The cost differences continue to pose challenges for the competitiveness of energy-intensive industries in the EU, IEA stressed.

APSTE: High state fees for PV panels, energy storage batteries inhibit electricity price decrease in Bulgaria

The Association for Production, Storage and Trading of Electricity (APSTE) warned that the government’s disproportionately high fees for photovoltaic panels and energy storage batteries are preventing the possibility of having permanently low electricity prices in Bulgaria. They also threaten the implementation of key projects under the National Recovery and Resilience Plan (NRRP).

The fees that the government charges don’t reflect the real recycling cost, given that they are five to 10 times higher than the average fees in the European Union, according to APSTE.

The product fee for solar panels is currently BGN 0.90 (EUR 0.46) per kilogram – over 11 times higher than the same levy in the Netherlands.

It increases the price of panels by about 35%, which leads to about a 10% increase in the cost of turnkey solar power plants, APSTE stressed.

The fees threaten the installation of 9,000 MWh of storage capacity

The impact is similar for lithium-ion batteries. With a rate of BGN 5.50 (EUR 2.81) per kilogram, the fee makes batteries nearly 19% more expensive. Another issue is that the cost isn’t foreseen in the business models of the projects financed under the National Recovery and Resilience Plan, according to the association.

It threatens the profitability of 9,000 MWh of storage capacity set to come online by the end of 2026, putting at risk one of the most important energy reforms in the country, the organization underlined.

Of note, in April, the Ministry of Energy approved EUR 587 million in subsidies for developers of 82 standalone battery storage projects, for an overall 9.71 GWh in capacity. The scheme is part of NRRP.

Gazdov: The government artificially increases the price of a panel by 35% and that of batteries by 19% 

The fees jeopardize future investments in battery energy storage systems (BESS), which are key to the operation of the electricity system and to reducing the price of electricity for end users, according to APSTE.

“It is absurd that the state artificially increases the price of a panel by 35% and that of batteries by 19% – just when solar power plants and storage systems are starting to provide a permanently low price for electricity,” APSTE chairman Nikola Gazdov stated.

In his words, there is no economic logic for the government’s fee for recycling batteries and solar panels in Bulgaria to be 10 times higher than in Central and Western Europe.

A similar case has occurred in Croatia. E.ON Croatia raised the issue of high waste fees on solar panels of EUR 300 per ton, up to six times more than in other European Union countries.

Outdated regulation threatens technologies that provide lower bills for people and industry

APSTE stressed that Bulgaria already covers a large part of its daily electricity consumption with solar energy, tumbling wholesale power prices to extremely low levels. Now BESS is starting to transfer the effect of cheap solar electricity to the evening peak consumption, when prices are traditionally higher.

At a time when Bulgarian households and businesses need cheap energy the most, outdated regulation with unreasonably high fees threatens technologies that already provide lower bills for people and industry, APSTE noted.

The association called on the government to urgently revise the regulation on product taxes, with the aim of bringing it to average EU levels:

  • Between EUR 50 and EUR 100 (BGN 100 to BGN 200) per ton, or BGN 0.10 to BGN 0.20 per kilogram of PV panels.
  • Between EUR 600 and EUR 1,000 per ton (BGN 1,200 to BGN 2,000 per tonne), or BGN 1.2 to BGN 2 per kilogram of lithium-ion batteries.

APSTE has submitted a letter addressing the matter to the Council of Ministers, the Ministry of Energy, and the Ministry of Environment and Water.

New systems protecting birds from wind turbine collisions

Wind power technology is often criticized because birds collide with turbine blades. As the number of wind farms in Southeast Europe grows, bird protection is increasingly important. A solution exists. Croatian environmental consultancy Oikon has become the regional representative for three systems that detect the presence of birds and temporarily halt wind turbines to prevent collisions and reduce the impact on biodiversity.

Wind farms produce clean energy and contribute to the fight against climate change. On the other hand, wind turbines can often harm biodiversity. Birds’ vision has evolved toward finding food and detecting predators—but not for avoiding tall turbine towers with fast-spinning blades. To help prevent bird collisions, so-called shutdown on demand (SDOD) solutions stop turbines when necessary.

SDOD refers to the temporary shutdown of turbines when individuals from protected or sensitive bird species are detected entering a high-risk collision zone.

Oikon is the regional representative for three bird detection and turbine control systems

Bird protection is increasingly important amid the wind energy expansion in Southeast Europe. Croatian environmental consultancy Oikon Ltd. – Institute of Applied Ecology announced that it has become the regional representative for three internationally recognized systems for bird detection and turbine control technologies.

SDOD is rapidly becoming a standard requirement for wind projects operating near sensitive bird habitats, Oikon’s CEO Dalibor Hatić says. “These technologies are already being requested by permitting authorities. We’re helping developers access proven and reliable systems to fulfil those obligations,” he asserted.

One of the systems that Oikon provides to its clients is IdentiFlight from the United States. It is three-dimensional, with artificial intelligence and high-speed cameras to identify birds in real time. Installed on separate towers, it gives optimal coverage of protected areas.

Max, developed by Dutch company Robin Radar Systems, uses a 3D radar specifically designed for bird monitoring. It enables the tracking of birds and bats over long distances, both day and night. The technology can simultaneously monitor and log thousands of flights with high precision.

AVES Wind, the third system in the portfolio, was developed by German company ProTecBird. The device is installed on the turbine itself. It combines pan-tilt-zoom cameras, real-time tracking software and AI to detect and identify bird species, calculate their 3D position, control turbine operations and generate documentation for regulatory compliance.

SDOD reduces bird mortality and energy production losses

Unlike long turbine curtailments or seasonal restrictions, SDOD is activated only when needed – when birds enter a risk zone. The approach reduces both bird mortality and energy production losses.

“Oikon’s role is to make these internationally proven technologies available in Southeast Europe and ensure their integration aligns with local ecological, technical, and regulatory conditions. The company supports developers in meeting the requirements set by the European Union and national nature protection laws, including mitigation measures often mandated by environmental authorities,” the company said.

It pointed out all SDOD systems can be used for research purposes and that they utilize high-quality military-grade resilient components and technology, ensuring their functionality regardless of weather conditions.

Serbia adopts Just Energy Transition Plan until 2030

Serbia now has a Just Energy Transition Plan until 2030. The document contains suggested measures for the mitigation of the impact of reducing fossil fuel use, primarily coal, so that workers, firms and communities aren’t left behind.

Following last month’s completion of the public consultation process regarding the proposed Just Transition Action Plan, the Government of Serbia passed, at its last session, the Just Energy Transition Plan of the Republic of Serbia until 2030. The document leans on the Integrated National Energy and Climate Plan (INECP or NECP)

It lays out sustainable energy policy measures that would need or could be undertaken. The point is in reducing fossil fuel dependence and improving security and efficiency of electricity supply by switching to renewable energy sources, and in an energy efficiency boost.

A just transition aims to promote environmentally sustainable economies in a way that is fair and inclusive for all

“A just transition aims to promote environmentally sustainable economies in a way that is fair and inclusive for all – workers, businesses and communities – by creating opportunities for decent work and leaving no one behind. This initiative should not be seen as a fixed set of rules, but as a dynamic process based on dialogue with a focus on addressing the concerns and needs of local populations and affected stakeholders,” the plan reads.

The approach is based on mitigating the negative effects of the energy transition process. It implies significant investments in retraining and reskilling, to assist workers in adjusting to new industries, as well as education, the plan adds.

It highlights the importance of incentivizing the development of new industries, and supporting small and medium-sized enterprises, which can enable alternative sources of income and employment.

Electricity system collapse in December 2021 marked as turning point?

Until December 2021, domestic electricity production met domestic needs, although even before that, the power system had been making maximum efforts for many years to provide sufficient amounts of electricity or, rather, provide sufficient amounts of coal for the operation of thermal power plants, the document notes.

There is no elaboration on the time reference, but that’s when a major outage struck coal-fired thermal power plants of state-owned power utility Elektroprivreda Srbije (EPS). Of note, it was one in a string of serious incidents in the electricity system.

Coal plants are old and they mostly don’t comply with environmental standards

“The fact is that existing electricity generation plants are old and most of them are not in line with new operating conditions and standards when it comes to environmental protection. Therefore, it is quite clear that in the case of the Serbian energy sector, the energy transition should lead to a radical change in the structure of sources and methods of electricity production,” according to the plan.

Coal plants, open pit mines could be replaced with wide range of activities from culture to gas power plants

Listed among the possibilities for repurposing coal plants and coal mine land after shutting them down are green power plants (but also gas-fueled energy facilities), launching industrial production, logistical and commercial activities, together with sports, culture, education, agriculture, tourism and waste management.

In 2023. there were 25,288 employees in thermal power plants (22.2%) and coal mines (77.8%), the document notes. The oldest coal plant, Kolubara A of 239 MW, was built in 1956, and the newest unit is Kostolac B3, of 350 MW. It came online last year.

“Social dialogue mechanisms should be established to ensure that the voices of all stakeholders are heard and their concerns are addressed. This includes consultations with trade unions, local self-governments and civil society organisations,” the Just Energy Transition Plan of the Republic of Serbia until 2030 suggests.

Expenses are envisaged at EUR 75.4 million, of which EUR 12 million would be for incentives for entrepreneurship and self-employment and EUR 60 million for improving business structure at existing industrial parks.

Carbon pricing system to make coal power plants in Serbia increasingly uncompetitive

One section covers the upcoming rollout of charges within the European Union’s Carbon Border Adjustment Mechanism (CBAM). The tax affects imports of a group of raw materials and electricity. Third countries can be exempted if they establish their own carbon pricing and emissions trading systems.

“In order to balance the economic and environmental impacts of the introduction of domestic carbon pricing in Serbia, a phased approach could be adopted, starting with a modest carbon price and gradually increasing it. Support for affected industries, such as subsidies for low-carbon technologies and worker retraining programs, along with recycling revenues to finance green projects and providing direct rebates to citizens, can mitigate negative effects,” the plan adds.

NGOs have criticized the action plan draft for only describing preparatory activities

Actually, proceeds from greenhouse gas emissions allowances in the EU are used only for the green economic transition, and it is similar with most environmental levies.

The introduction of a carbon tax mechanism will make domestic coal-fired power plants increasingly uncompetitive, especially in regional electricity markets, the government warned.

Nongovernmental organizations and associations earlier criticized the draft, arguing that it delays the energy transition until 2030, only lists preparatory activities and that, inter alia, there is no targeted date for ending the use of coal for electricity production.

In any case, a just energy transition requires defining deadlines and projects and securing funds exclusively for the said purposes. Otherwise the market will trample coal plants and mines, and it will probably happen abruptly, which would jeopardize energy security and employment. Such effects are already tangible in Southeastern Europe, especially in Bosnia and Herzegovina, as well as in Bulgaria and Slovenia.

BiH’s electricity imports up 4.5 times

Bosnia and Herzegovina’s electricity imports were nearly 4.5 times higher in the first half of the year than in the same period of 2024.

The step rise in power imports is another evidence of the difficult situation in the country’s utilities – Elektroprivreda BiH (EPBiH), Elektroprivreda HZHB (EPHZHB), and Elektroprivreda Republike Srpske (ERS).

The main issue is the drop in production in coal power plants and hydropower plants. For many years, BiH was the only net electricity exporter in the Western Balkans; however, it seems a change is underway. The country finished last year with 2.5 TWh in net exports – 36% less than in 2023.

Most imports occurred during the winter

According to data from the Agency for Statistics of BiH, electricity imports in the first half of last year amounted to BAM 78.8 million (EUR 40.3 million), while in the same period this year they reached BAM 344 million (EUR 175.9 million), Nezavisne novine reported. It is a 337% increase.

The data show that the majority of imports took place in the first quarter or during the winter. In the first three months of last year, import costs came in at BAM 33.7 million (EUR 17.2 million), and this year they soared to BAM 235.4 million (EUR 120.3 million) from January through March.

Exports also recorded an increase on an annual scale. In the first half of 2025, they were worth BAM 439.4 million (EUR 224.6 million), against BAM 289.3 million (EUR 147.9 million) in the equivalent period of last year. It is a 52% increase.

Coal and hydrology issues soured the foreign balance in the electricity sector

Just under half of exports were achieved in the first three months of the year.

ERS struggled with power generation in coal power plants due to longer maintenance and a lack of coal. EPBiH has also been facing coal supply problems for years. Both companies are unable to produce sufficient quantities of coal from their own mines.

An additional issue this year is the drought, which has reduced production in hydropower plants. Unfavorable hydrological conditions are affecting all three companies, but the largest pressure is on EPHZHB, which operates only hydropower plants.

Energy expert Almir Bečarević asserted that import figures reflect reality.

He explained that two thermal power plants in the Republic of Srpska were undergoing maintenance, and that EPBiH is facing issues with hydrology and its mines, which cannot supply sufficient quantities of coal.

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.
