Record-Breaking Tolling Agreement

Statkraft and Greenvolt Power have signed a landmark 10-year battery storage tolling agreement covering 400 MW and 1.6 GWh across two projects in Poland. The deal encompasses the Ełk and Turośń Kościelna sites, each featuring 200 MW / 800 MWh capacity. This marks the largest publicly disclosed BESS tolling deal in the European Union to date, with the tolling term running until approximately 2036.

Financial Backing and Revenue Structure

The agreement is underpinned by a separately closed €218 million financing package from UniCredit, comprising a €153 million bridge loan and a €65 million guarantee. This milestone confirms the bankability of utility-scale BESS in Poland without requiring all offtake contracts to be finalized beforehand. Under the tolling structure, Statkraft assumes operational control, capturing market revenues from trading and flexibility services. Greenvolt retains asset ownership and receives predictable contracted tolling income, layered on top of capacity market revenues from a 17-year, 170 MW obligation starting in 2028.

Hardware and Expansion

Battery hardware for both installations was supplied by BYD Energy Storage, likely utilizing the MC-Cube T variant. The Turośń Kościelna project was inaugurated in July 2026, while the Ełk project targets Q4 2026 for commercial operation. Furthermore, Greenvolt has commenced construction on the massive 600 MW / 2.4 GWh Siedlce BESS. This new facility will feature 210 battery containers and 105 transformer containers utilizing BYD technology, pushing Greenvolt's operational and under-construction portfolio in Poland to 1 GW and 4 GWh. The company plans to invest around €800 million in Polish renewable energy projects by the end of 2026.

This transaction highlights the growing maturity of the Polish BESS market, supported by forecasts that European battery storage growth will jump 78% in 2026.
