Poland’s battery energy storage buildout outlook

Poland’s utility‑scale battery storage market is entering a transformative growth phase, with four capacity‑market auctions between 2022 and 2025 contracting an estimated 5.1 GW of deliverable BESS capacity - equivalent to at least 11 GW of physical battery capacity after de‑rating. By 2030, Modo Energy estimates that operational utility‑scale BESS capacity in Poland could reach 8–9 GW, up from just 28 MW today, driven by a pipeline of 89 projects totaling 12.5 GW and supported by over €1 billion in state subsidies. However, grid connection constraints and project attrition mean that turning this pipeline into realised capacity will depend on how quickly developers can secure grid access and navigate permitting and financing hurdles.
