R.Power Initiates Construction of 254MWh Battery Storage in Romania as TSO Launches 70MWh Tender

R.Power to Construct 254MWh BESS in Romania; TSO Seeks 70MWh EPC Tender

R.Power Renewables, primarily known as a solar independent power producer (IPP), is expanding into large-scale energy storage projects. The company announced plans to begin construction on a significant battery energy storage system (BESS) in Romania and another in Poland in the latter half of this year. Concurrently, Romania’s transmission system operator (TSO) is seeking engineering, procurement, and construction (EPC) services for its own BESS project.

The announcements were made via LinkedIn, highlighting projects that have secured funding through the financial support schemes of the Romanian and Polish governments.

### R.Power’s Projects in Romania

In Romania, R.Power will commence construction on the 127MW/254MWh Scornicesti BESS project in the third quarter of 2025. This facility will connect to the high-voltage network operated by Transelectrica, with construction expected to be completed by the third quarter of 2026. The project aims to provide essential system support services and enhance the balance of renewable energy generation.

R.Power has received RON74.6 million (approximately USD 17 million) in capital expenditure support from the Ministry of Energy, funded by Romania’s share of the EU-wide Recovery and Resilience Plan (PNRR). Last year, this scheme in Romania supported approximately 2.5GWh of various projects.

Romania has been a focal point for significant technological advancements recently. Notably, it could be the site for the initial deployments of BESS utilizing the 1,175Ah cell from Chinese lithium-ion manufacturer Hithium, as indicated in the company’s latest announcements. Moreover, in April, Hidroelectrica, a power generation company, partnered with local firms Prime Batteries Technology and Enevo for a BESS project.

### Transelectrica’s 70MWh Tender

In related developments, Transelectrica has issued a tender for the EPC package of a 35MW/70MWh BESS project located in Fantanele, Mures County. This tender encompasses the BESS and associated work for the 110kV/MV substation. A spokesperson emphasized the need for suppliers with proven experience in electricity storage who can meet stringent quality standards and timelines.

### R.Power’s Expansion into Poland

In addition to its Romanian project, R.Power has plans to build a BESS in Poland, with construction set to begin in the fourth quarter of 2025. The 5MW/10MWh Herby BESS is expected to become operational in the first quarter of 2026 and will connect to the distribution network of Tauron Dystrybucja. This project marks R.Power’s inaugural standalone initiative in Poland and has secured a contract in the capacity market (CM) for delivery scheduled in 2029. Approximately 2.5GW of BESS projects were awarded contracts in the recent auction, which provided long-term agreements at PLN 264.90/kW/year. This figure represents a notable increase from the 1.7GW of BESS projects that received contracts in 2023, which was already ten times higher than in 2022. The capacity market is crucial for establishing a viable business case in Poland.

R.Power is also promoting a larger 150MW/300MWh Jedwabno BESS project in Poland, with a planned commercial operation date in 2026, although no official announcements have been made regarding this project.

These announcements come just months before the Energy Storage Summit Central Eastern Europe 2025, scheduled to take place in Warsaw, Poland, on September 23, 2025. This summit will focus on regional markets and the unique opportunities presented by the evolving landscape of energy storage, government policies, and the increasing demand for energy security.
