R.Power in line for capacity market contracts for 4 GWh of BESS projects in Poland

Polish independent power producer R.Power Renewables has announced that it won five capacity market contracts in the December capacity market auction for the delivery year 2030.

In a December 11 stock exchange filing, the company said it won contracts covering no less than 134 MW of capacity obligation. Its energy storage facilities fulfilling these obligations would have a combined output of 1,012 MW and total capacity of approximately 4,032 MWh, adjusted by a 13.39% derating factor.

If finalized, the contracts could generate at least PLN 1.3 billion in revenue over 17 years, with prices indexed annually to the consumer price index. R.Power’s Polish battery storage portfolio would then total 1.7 GW / 6.3 GWh under capacity agreements.

The Warsaw-based company is also developing three large-scale battery projects totaling 650 MW / 2,300 MWh, making it one of the largest energy storage portfolios in Central and Eastern Europe. These projects secured 17-year capacity market contracts in Poland’s December 2024 auction, clearing at PLN 264.90/kW/year ($65/kW/year).

On December 15, transmission system operator PSE SA published the preliminary results of the 2030 capacity market auction, setting the auction closing price at PLN 465.02/kW/year ($128/kW/year).

PGE reported that a total of 1,399.218 MW of capacity obligations were ultimately contracted for entities within the PGE Group, including 44.028 MW in 17-year contracts, 1,097.718 MW in 15-year contracts, 210.472 MW in 7-year contracts, and 47.000 MW in annual contracts.

The final results of the capacity auction are announced by the President of the Energy Regulatory Office in the Public Information Bulletin on the first business day after the 21st day following the auction’s conclusion.

Last year, the Polish capacity market auction for 2029 awarded more than 8 GW of capacity contracts with about 2.5 GW allocated to “new generation” units, i.e., BESS projects ranging from 1.2 MW to 153 MW in rated power.

Opinion & Analysis

Battery storage on a capacity market In Germany – but not only there – there is a heated debate about the pros and cons of a capacity market. The German Renewable Energy Association is against it, and recently the German New Energy Industry Association, the DIHK and the EEX energy exchange have also taken a clear stance: Germany does not need a “power plant subsidy program.” In this article, four experts explain why battery storage can also play an important role in a capacity market and make recommendations on how the design of the market can help avoid mismanagement, wrong incentives and unnecessary costs.

Poland’s new capacity market auction could hamper BESS The draft parameters for this year’s capacity market auction in Poland could make the rollout of battery energy storage systems (BESS) much more difficult. The document proposes a significant reduction to the BESS derating factor that could be particularly harmful for longer duration storage systems.
