Poland finalizes 5 GWh energy storage subsidy
Eligible projects include the construction of storage facilities with a minimum power rating of 2 MW and a capacity of at least 4 MWh,
Max. Efficiency Get your Exclusive Offer! Polinovel 2MWH commercial energy storage system (ESS) is tailored for high-capacity power storage, ideal for large-scale renewable energy generation, PV self-consumption, off-grid applications, peak shaving, and emergency backup power.
With the rising share of intermittent renewable power, large-scale battery storage systems are becoming critical to maintaining grid stability. By addressing challenges such as peak load balancing and frequency regulation, energy storage enhances the resilience and flexibility of Poland's electricity system.
The scheme has been brewing since 2024, with the final regulation published in the Journal of Laws of the Republic of Poland in March this year. It received European Commission approval, which authorised state aid of €1.2 billion in state aid to support at least 5.4 GWh of new electricity storage facilities.
The Polish Economic Institute noted that in December 2024's power market auction alone, approximately 2.5 GW of storage capacity was contracted – a 44% jump over the 1.7 GW contracted in 2023. This growth trajectory looks set to continue as renewable penetration ramps up and grid stabilisation becomes more critical.
