Croatian company Brodosplit delivers equipment for French floating wind farm pilot project

Croatian shipbuilding company Brodosplit has manufactured steel structures for the floating foundations of an offshore wind farm in one of the first such pilot projects in France.

The site for the EolMed project is approximately 18 kilometers from the coastal town of Gruissan in the Occitanie region of southern France.

Qair is leading the consortium, which includes oil and gas giant Total Energies and floating platform provider BW Ideol as its partners. The three 10 MW wind turbines, supplied by Vestas, are about to be installed at a spot where the sea is 55 meters deep.

According to Brodosplit, the project has entered its final phase after the successful launch of the three floating platforms in September.

It isn’t Brodosplit’s first floating wind farm project

The Croatian firm said it manufactured and delivered the metal structures for the floating foundations, in line with the highest quality and safety standards.

Before joining the EolMed project, it entered the floating wind farm segment through cooperation with Ocergie. Brodosplit has created an innovative measuring buoy, OCG-Data, for the France-based company’s Blue Oracle project.

The EolMed project received state support as part of the investments for the future program

The buoy is equipped with a LiDAR (light detection and ranging) system and advanced sensors for monitoring wind, waves, currents, and sea biodiversity, enabling the collection of crucial data for the development of floating wind farms and the preservation of the marine environment, Brodosplit pointed out.

Since EolMed’s initial design in 2016, it has been adjusted and adapted to incorporate the latest technologies. Initially comprising four wind turbines, the number has since been reduced to three for equivalent capacity.

The change also affected the choice of material for the floats – now steel instead of concrete. Construction began in April 2023, and completion is planned for this year.

The project received state support through the Investments for the Future Programme (Programme d’Investissements d’Avenir – PIA). The goal is to demonstrate the economic viability of floating wind farm technology.

Europe’s Environment 2025 report: Not good

Biodiversity is declining and water stress is affecting one third of Europe’s population and territory, while the frequency and magnitude of climate-related disasters are increasing. In short, this is the message from the report Europe’s Environment 2025.

​Europe’s Environment 2025 is the most comprehensive analysis on the current state and outlook for the continent’s environment, climate, and sustainability, building on data from across 38 countries, according to the European Environment Agency (EEA).

The outlook for most environmental trends is concerning and poses major risks to Europe’s economic prosperity, security, and quality of life, the authors warned. The agency said climate change and environmental degradation pose a direct threat to Europe’s competitiveness, pointing out that it depends on natural resources.

Progress on a range of factors that enable the shift towards sustainability – such as innovation, green employment, and sustainable finance – gives cause for hope, EEA added.

​More than 80% of protected habitats are in a poor or bad state

The report shows biodiversity is declining across terrestrial, freshwater, and marine ecosystems in Europe due to persistent pressures driven by unsustainable production and consumption patterns, demonstrated most notably in the food system.

More than 80% of protected habitats are in a poor or bad state, with 60% to 70% of soils degraded, the document reads.

On a positive note, the extent of protected areas increased over the past decade – by 2022, 26.1% of the European Union’s land and 12.3% of its seas were protected. However, designating protected areas alone does not guarantee that biodiversity is effectively protected, the authors wrote.

​Water stress is affecting one third of Europe’s population and territory

The report’s findings point to severe pressure on water resources: water stress is affecting one third of Europe’s population and territory.

Only 37% of surface water bodies had a good or high ecological status in 2021, with the degradation of aquatic ecosystems threatening Europe’s water resilience. Agriculture is responsible for the most significant pressure on both surface and groundwater, data revealed.

EEA recalled that Europe is the fastest-warming continent on the planet.

Weather- and climate-related extremes caused economic losses of assets estimated at EUR 738 billion in the EU’s 27 member states over the period 1980-2023, with over EUR 162 billion in costs from 2021 to 2023 alone, the report reads.

Over 70,000 people in Europe are estimated to have died from heat in 2022.

The average annual economic losses in the 2020‑2023 period were 2.5 times as high as in the preceding decade, from 2010 to 2019, according to the report.

Downpours are increasing in severity, with several regions subject to catastrophic floods in recent years, while extreme heat, once rare, is becoming more frequent, with deadly consequences: over 70,000 people in Europe are estimated to have died from heat in 2022.

The greatest challenges call for a need to rethink the links between the economy and the natural environment, land, water and natural resources, EEA underscored.

“We cannot afford to lower our climate, environment and sustainability ambitions. Our state of environment report, co-created with 38 countries, clearly sets out the science-based knowledge and demonstrates why we need to act. In the European Union, we have the policies, the tools and the knowledge, and decades of experience in working together towards our sustainability goals. What we do today will shape our future,” EEA Executive Director Leena Ylä-Mononen said.

Bright spots

The report also highlighted the good results of environmental protection policies in Europe.

The EU has cut its domestic greenhouse gas (GHG) emissions by 37% since 1990, largely driven by reducing fossil fuel use and doubling the share of renewables since 2005.

All member states have reduced their reliance on fossil fuels and shifted towards more sustainable energy sources over the last decade, while increased energy efficiency has brought down demand.

In 2023, renewable energy sources represented over 24% of the EU’s final energy use, a record high.

The bloc’s industrial system has managed to reduce emissions by more than 35% from 2005 to 2023, while emissions from buildings fell by more than 35% between 2005 and 2023.

Significant progress has been made in reducing pollution in Europe. EU policies led to improvements in air quality and reduced premature deaths attributable to fine particulate matter from 2005 to 2022 by 45%, according to the Europe’s Environment 2025 report.

Croatia’s HEP to install 90 solar power plants on rooftops of its facilities

Croatia’s power utility Hrvatska Elektroprivreda intends to install 90 solar power plants on its facilities across Croatia.

HEP ESCO, a subsidiary of Hrvatska Elektroprivreda (HEP), has launched a public procurement for the installation of 90 photovoltaic plants under a design-and-build model and on a turnkey basis.

The firm develops, implements, and finances energy efficiency projects based on the ESCO model.

The investment is estimated at EUR 5.3 million, and the deadline for submitting bids is November 3.

HEP ESCO plans to sign a contract with the best bidder within 90 days after selecting it. The deadline for the completion of works will be 18 months, according to the public call.

Five groups of solar power plants

The public call is divided into five geographical groups in Croatia.

Group 1 is for Zagreb and its surroundings. Solar panels would be installed at ten locations, with an estimated investment of EUR 1.2 million. Group 2 covers hydropower plants Zavrlje, Orlovac, Peruća, and Zakučaci in the coastal region of Dalmatia, as well as power distribution facilities. The works in the segment are valued at EUR 770,000, local media reported.

Four cities in the region of Slavonia make up the third group, with 20 locations. Solar panels would be installed for EUR 1.21 million in Virovitica, Požega, Vinkovci, and Vukovar.

HEP has over 50 solar power plants on the rooftops of its buildings and facilities

A total of 15 locations in the areas of Međimurje and Zagorje and the Sisak-Moslavina county, and including hydropower plant Ozalj, all in northwestern Croatia, are in the fourth group. The estimated value is EUR 1.1 million.

The value of the investment in Istria, Primorje, and Gorski Kotar is EUR 1.03 million. It entails the Fužine hydropower plant, Rijeka, Vinodol, and electricity distribution facilities.

Of note, HEP has more than 50 solar power plants on the rooftops of its buildings and facilities.

HEP Proizvodnja, HEP’s power production arm, has 12 PV plants on administrative buildings, thermal power plants and hydropower plants. The total capacity is about 1.5 MW. HEP ODS, the country’s distribution system operator, has another 44 solar power plants with a total capacity of 1.1 MW on its roofs.

Batteries totaling 5,899 MWh in grid connection procedure in Serbia

Investors in Serbia are obtaining approvals for connecting their planned battery energy storage systems of an overall 2,021 MW and 5,899 MWh to the grid. The projects are for standalone batteries and ones that would be co-located with power plants.

Battery energy storage systems (BESS) are rapidly expanding worldwide, and Southeast Europe is no exception. European Union member states in the region such as Bulgaria and Romania are making major strides, while the other countries are trying to catch up. For example, Bosnia and Herzegovina, Montenegro, North Macedonia and Serbia.

As of September 29, Serbia’s transmission system operator (TSO) Elektromreža Srbije (EMS) received a total of 12 applications for the development of connection studies for standalone BESS, Nebojša Vučinić, manager of the Development Division of EMS, told Balkan Green Energy News.

Two applications were submitted in January for the study development interval of March 1 to June 30, 2025, and ten more were received for the current interval, which lasts from September 1 to December 31. Out of the first two applications, the one from Green BESS KV is no longer valid, because the firm didn’t submit a bank guarantee.

EMS develops connection studies every year in two intervals.

The following companies are in the process of connecting standalone BESS:

  • MKBDP Energy
  • Green Land New Energy
  • Green Mountain New Energy
  • BP WPP
  • Blue BESS KV
  • Red BESS KV
  • Yellow BESS KV
  • ENLIGHTNES PV OPERATIONS
  • ENLIGHTNES PV PARK
  • Gridflex

As for the status of their applications, MKBDP Energy has submitted a bank guarantee, and the signing of the grid connection contract is expected.

For the other ten requests, the grid connection studies are underway. They are expected to be completed by December 31.

Standalone storage facilities are planned in Valjevo, Vranje, Subotica, Kovačica, Vršac, Leskovac, Kragujevac, Kruševac, Jagodina, and Ćuprija.

A total of 55 battery projects are in the connection procedure

The 11 standalone storage projects amount to 1,072.66 MW and 2,981.98 MWh altogether, Vučinić said.

The 44 storage facilities that would be co-located with power plants utilizing variable renewable energy sources would have 948.46 MW and 2,917.31 MWh, as stipulated in the Law on the Use of Renewable Energy Sources.

All battery storage projects in the grid connection process amount to 2,021.12 MW and 5,899.29 MWh, Vučinić stressed.

MKBDP Energy’s project has advanced the most in the connection process

According to Vučinić, implementation of BESS projects depends on the progress that an investor achieves. Currently, MKBDP Energy’s investment has passed the most milestones in the connection process, he added.

EMS noted that the grid connection process for standalone battery storage is defined by the Law on Energy and bylaws.

The deployment of standalone batteries complements the integration of power plants running on variable renewable sources

The state-owned company sees no obstacles to integrating standalone BESS into the transmission system. The TSO expressed commitment to assisting investors while maintaining the safety of the entire power system’s operation.

EMS also called the increase in applications for standalone batteries a positive development.

The emergence of standalone batteries complements the integration of power plants utilizing variable renewable energy, and since a large number of such power plants are expected to be connected, the integration of standalone storage helps the power system’s flexibility and safety, Vučinić underlined.

European day-ahead power market rolls out 15-minute trading intervals

The Single Day-Ahead Coupling area split its hourly units into 15-minute intervals for electricity trading. The change, affecting most European markets, is aimed at enhancing the integration of renewables by making flexibility and balancing more efficient.

After delays and intensive testing, the European wholesale electricity market switched to a 15-minute market time unit (MTU) from hourly blocks within the Single Day-Ahead Coupling (SDAC) mechanism. The transition was implemented across all bidding zones and bidding zone borders, according to the All NEMOs Committee, gathering nominated electricity market operators.

Thirty transmission system operators were involved in the move, aimed at creating an integrated pan-European cross-zonal day-ahead electricity market. Only Great Britain, Switzerland, the Western Balkans, Turkey and Cyprus, the European Union’s only non-interconnected member state, are outside of the SDAC region.

The first trading sessions were held at power exchanges yesterday, for delivery today. So far there were no indications of glitches with the quarter-hourly products.

A more than a year-long testing campaign for the 15-minute MTU solution included the validation of local, regional and cross-border functionalities, verification of connectivity between parties and confirmation of overall system readiness, the Market Coupling Steering Committee, MCSC, said last month.

Also of note, Cyprus launched its electricity exchange yesterday, with day-ahead, forward and balancing markets. In spot trading, the interval is 30 minutes.

Benefits from trading blocks with shorter intervals

The European Union is pushing the electricity market to improve efficiency by matching production and consumption more accurately. With the rising shares of solar and wind power in the energy mix, the frequency and intensity of fluctuations from weather changes are growing as well.

As the energy transition and digitalization progress, market time units could get shorter and shorter

The 15-minute interval captures the changes better than the one-hour block, reducing balancing needs and costs and freeing up capacity. As the energy transition and digitalization progress, market time units could get shorter and shorter. Importantly, it implies an exponential rise in computing power.

Wind and clouds aren’t very predictable, so unmatched production forecasts cause imbalances. It can burden the intraday market, where they are corrected. Shorter intervals lower the deviations.

Opportunity for battery storage deployment

With 15-minute products, more short-term fluctuations will already be captured in the day-ahead auction, Vattenfall said in a comment.

“Generation and demand can now be mapped much more precisely. We can submit more accurate forecasts, market renewables more effectively, deploy batteries and pumped storage more efficiently, and significantly increase system flexibility,” the company’s Head of Short-Term Asset Optimization Jörg Seidel pointed out.

Consumers could also benefit, according to the Swedish energy producer and supplier. More precise price signals open new savings potential through dynamic tariffs and smart meters, enabling households to use electricity when it is cheapest, it explained. It could make heat pumps, photovoltaic systems, batteries, and electric vehicle charging more efficient and affordable.

“Flexibility is becoming the currency of the energy transition,” Seidel stressed.

Nevertheless, nothing changes for small consumers including households until they get an electricity meter that can track quarter-hourly blocks.

With higher fluctuations in shorter intervals, opportunities arise for operators of battery energy storage systems (BESS) and other storage and balancing technologies, which stabilizes the electricity system. The switch to the 15-minute MTU is mostly beneficial for aggregators as well, reducing their exposure to penalties for failing to meet forecasted levels of production.
