Poland launches 1 billion zloty subsidy program for home energy storage

Funding structure and subsidy caps

Poland's Ministry of Climate and Environment announced a 1 billion zloty support program on Friday to subsidize home energy storage and heat storage systems for individual prosumers. Under the framework, households operating in the net-billing settlement system can receive up to 16,000 zlotys for electricity storage units, while prosumers remaining in the older net-metering system can access up to 8,000 zlotys. Net-billing requires prosumers to sell surplus power through a billing account and buy it back as needed, whereas net-metering used quantitative discounts. Applicants can obtain up to 1,000 zlotys for installing a heat storage unit, alongside an additional premium of up to 2,000 zlotys if the purchased equipment was manufactured in the European Union. In total, maximum support reaches 19,000 zlotys per energy intake point, covering electricity storage, heat storage, and inverter replacement.

Equipping home photovoltaic installations with energy storage is one of our priorities. The program has two main goals: increasing the efficiency of renewable energy use and strengthening energy security. Energy storage facilities not only allow better use of energy produced for own needs, but also ensure the possibility of running the installation independently of the grid in emergency situations.

Technical criteria and eligibility

The program targets natural persons who are prosumers with renewable micro-installations connected to the power grid, limited to capacities of up to 50 kWp. Qualifying electricity storage units must provide a minimum capacity of 10 kWh, while heat storage devices must have a volume of at least 100 litres. Beneficiaries must also equip their installations with an Energy Management System (EMS) and ensure islanding functionality, which allows the home to maintain backup electricity during local power grid failures. Deputy Minister Sławomir Ćwik noted that less than 10% of prosumers in Poland currently own energy storage units on their properties. The ministry expects the new funding to increase aggregate residential storage capacity across Poland to over 2 GWh.

We estimate that after completing this program, the energy that can be stored in home storage facilities will exceed 2 GWh.

Grid integration and market growth

The initiative builds on an earlier support phase funded by the National Recovery Plan (KPO), which allocated approximately 112 million zlotys to subsidize more than 5,000 residential battery systems. In the middle of 2026, Poland's electrical power system contained roughly 150,000 energy storage devices, with approximately 20,000 new units added every quarter without dedicated subsidies. Climate officials project that the newly launched scheme will expand the total number of residential storage units in the power grid to around 200,000 by the end of 2026. The ministry explained that battery installations support grid stability and household finances by storing power when market prices are low and discharging it during higher demand periods.

Application schedule and execution

The National Fund for Environmental Protection and Water Management (NFOŚiGW) will run the application intake from 20 October 2026 until 1 October 2027. The program includes retroactive financing for equipment purchased from 1 November 2025, enabling homeowners who already acquired qualifying units to seek reimbursement. Eligible prosumers can submit applications directly to NFOŚiGW during the open call period to claim reimbursements for battery storage, heat tanks, and replacement inverters. The ministry confirmed that the 1 billion zloty budget will be distributed to applicants meeting the technical and billing requirements until the deadline in October 2027.
