Actis buys 244 MW / 1,141 MWh of Polish batteries backed by 17-year capacity contracts

Infrastructure investor Actis announced on 6 October that it is acquiring two battery energy storage projects in Poland from developer DRI, adding 244 MW / 1,141 MWh to the Polish renewables platform it launched in July.

The two assets, and how each changes hands:

• Kozienice — 112 MW / 518 MWh. Already acquired and, per Actis, ready for construction.
• Trzebinia — 132 MW / 623 MWh. Signed, with completion set for when the project is operational, so the developer carries it through to commercial operation.

Both are described as four-hour-plus systems — 1,141 MWh over 244 MW works out to about 4.7 hours — and both have revenue secured through a 17-year, inflation-indexed capacity market contract. Actis says they will be among the first utility-scale BESS in Poland to reach commercial operation; the release gives no target dates.

Why the structure matters. The two halves of the deal split construction risk differently: on Kozienice the buyer takes it, on Trzebinia the seller does until the plant runs. The common factor is the capacity contract, which is what makes a long-duration battery financeable before anyone knows what Polish arbitrage spreads will look like in the 2030s.

The platform. In July Actis bought Klara Renewables, a 171 MW onshore wind portfolio with about 275 MW of hybridisation potential; the batteries are meant to sit alongside generation to dampen volatility and capture value across the system. Actis says it targets 1.5 GW of wind, solar and storage on its Central and Eastern European platform and has committed more than US$1.1 billion across three platforms in the region.

The market case, as Actis states it. Poland is expected to retire about 18 GW of coal while adding 50 GW of renewables and 14 GW of gas by 2040, and electricity demand is forecast to more than double by 2050 with industrial and transport electrification. The release presents these as context without naming the forecasts' source, and attaches a standard disclaimer that its statements are the firm's views and not research.

DRI's chief executive, Murat Cinar, said the projects would provide significant flexibility to the grid as the renewable share grows.
