BESS market and revenue outlook in Poland

Poland’s renewable expansion is accelerating faster than the grid can adapt. Solar PV and wind now drive frequent stability challenges, pushing battery storage to the centre of the country’s energy transition. Recent market reforms (including new ancillary-service opportunities, capacity-market adjustments, and a PLN 4 billion national subsidy scheme) have created strong momentum for large-scale BESS deployment.

This white paper outlines:

• How rapid solar and wind growth is reshaping system-stability needs.
• The role of the NFOŚiGW subsidy scheme in scaling storage through 2028.
• How capacity, ancillary, and wholesale markets influence revenue potential.
• Where standalone and co-located BESS fit within Poland’s evolving power mix.
   

The S&P Global Commodity Insights projections highlight the scale of this shift.

Cumulative additional storage capacity is expected to rise steadily through 2030, with standalone systems leading growth and increasing uptake across residential, C&I, and co-located installations. This trajectory reflects Poland’s push toward greater flexibility as renewables continue to outpace grid readiness.

To dive even deeper into these topics, join the Solarplaza Summit Poland PV & Storage, taking place in Warsaw on 12 May 2026. The conference brings together the key investors, developers, and decision-makers shaping Poland’s solar and storage landscape. Now in its 6th edition, this event serves as the meeting point for Poland’s PV and BESS leaders to define the next phase of the country’s renewable energy growth.
