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.

Croatian Bank for Reconstruction and Development secures EUR 50 million for firms for green investments

The Croatian Bank for Reconstruction and Development has secured EUR 150 million from the European Investment Bank, of which at least one third is dedicated to green investments by businesses in the country.

A new finance contract with the European Investment Bank (EIB) provides EUR 150 million to finance projects of mid-caps, large private companies and public entities in Croatia, the Croatian Bank for Reconstruction and Development (HBOR) said.

The loan particularly promotes green investments. It is the first tranche of a new EUR 350 million financing agreement between the EIB and HBOR to expand access to financing for Croatian companies.

The package will be deployed via direct lending by HBOR and through commercial banks and other financial intermediaries.

At least 30% of the financing is for projects contributing to green transition

At least 30% of the financing is for projects contributing to green transition, including investments in energy efficiency, renewable energy sources, sustainable construction and clean transport, Croatia’s bank noted.

According to EIB Vice-President Teresa Czerwińska, the initiative will expand financial support to a broad range of Croatian companies and public entities, with a strong emphasis on climate action and sustainability.

The operation is structured as a multi-beneficiary intermediated loan (MBIL). In addition to advancing the European Union‘s goals to promote climate action and environmental sustainability, it will help foster economic activity and social cohesion across Croatia, HBOR said.

The EIB and HBOR have concluded 28 finance contracts worth EUR 3.8 billion overall

HBOR will ensure, as it has so far in cooperation with EIB, that all end-beneficiaries comply with relevant national and EU legislation, with a special focus on preserving environmental, climate and social standards.

The new financing further reinforces HBOR’s role in supporting green and climate-resilient projects, contributing to the achievement of the strategic goals of Croatia and the European Union for the ​​green transition, according to Hrvoje Čuvalo, President of the Management Board of HBOR.

EIB and HBOR have concluded 28 finance contracts so far, worth EUR 3.8 billion, for financing more than 8,000 projects across Croatia.

Prosumers in Romania are neck and neck with commercial PV plants in capacity

The latest data showed that prosumers in Romania don’t have a much larger total capacity anymore than commercial solar power plants, a segment accelerating in expansion. The share of units for self-consumption that include energy storage reached 5.8% in the first half of the year, compared to 1.2% six months earlier.

Total number of prosumers in Romania increased by 8,950 in June, to 237,252, Profit.ro reported. The installed capacity, consisting overwhelmingly of photovoltaic panels, rose by 95 MW, to 2.82 GW, the media outlet added, citing data from the National Energy Regulatory Authority (ANRE).

Total installed capacity of large, commercial solar parks is 2.77 GW, according to the article. Both segments are expanding strongly, but the latter has lately accelerated, with new utility-scale PV facilities coming online week after week. Of note, wind power and battery energy storage systems (BESS) are catching up.

On that note, 5.8% of prosumers also had batteries integrated with their self-consumption units on June 30. It compares to 1.2% at the end of last year.

Prosumers have led the energy transition for the past two years. Their overall capacity surpassed 2 GW just a year ago, translating to 37% growth in ten months.

Output in the segment amounted to 434 GWh in the first half of the year, where net domestic consumption declined 1% and net energy production surged 10%. Namely, as the duration of the daily solar radiation interval rose, prosumers in Romania drew less power from the grid and consumed more of what they generated themselves.

At the end of the first half of 2025, 210,714 households were prosumers, versus 26,538 legal entities. They had 1.34 GW and 1.48 GW installed, respectively.
