R.Power in Romania
The company will start construction on the 127MW/254MWh Scornicesti battery energy storage system (BESS) project in Romania in Q3 2025.
It will connect to the high-voltage network of transmission system operator (TSO) Transelectrica and construction is set to conclude in Q3 2026. It will provide system support services and help to balance out renewable generation.
R.Power secured RON74.6 million (US$17 million) in capex support from the Ministry of Energy, funded by Romania’s portion of the EU-wide Recovery and Resilience Plan (PNRR) scheme. The scheme in Romania funded around 2.5GWh of projects in total last year.
Romania has been at the centre of recent noteworthy technology announcements. The first deployments of BESS using Chinese lithium-ion OEM Hithium’s 1,175Ah cell could be there, based on the company’s recent announcement. In addition, power generation firm Hidroelectrica enlisted local firms Prime Batteries Technology and Enevo for a BESS project in April.
Electrica tendering work for 35MW/70MWh BESS
In related news, power and utility firm Electrica has also launched a tender for the engineering, procurement and construction (EPC) package for a 35MW/70MWh BESS project in Fantanele, Mures county. The tender includes the BESS and the related works for the 110kV/MV substation.
“We are looking for suppliers with proven experience in the field of electricity storage who can deliver high-quality results on time and in accordance with our strict standards and requirements,” a spokesperson said.
The full details of the tender (in Romanian) can be found here.
R.Power also building in Poland
Just prior to announcing the Romania project, R.Power also said it would start building a BESS in Poland in Q4 2025.
The 5MW/10MWh Herby BESS is set to come online in the first quarter of 2026 and will connect to the network of distribution system operator (DSO) Tauron Dystrybucja.
It is the company’s first standalone project in Poland, and it secured a contract in the capacity market (CM) in 2024 for delivery in 2029.
Around 2.5GW of BESS projects won contracts in the auction, securing long-term contracts paying PLN 264.90/kW/year. That was an increase on the 1.7GW of BESS that won in 2023, which itself was ten times the amount that won in 2022. The CM is the bedrock of the business case for Poland.
R.Power also lists a larger, 150MW/300MWh Jedwabno BESS project in Poland on its website, also with a planned commercial operation date (COD) in 2026, although hasn’t made any news announcements.
The flurry of announcements comes a few months ahead of Energy Storage Summit Central Eastern Europe 2025 in Warsaw, Poland.
This article was amended after publication, having initially misreported who was building the 35MW/70MWh project.
