Poland: Up to 19,000 PLN from NFOŚiGW for Home Energy Storage: Who Is Eligible for Subsidies and Under What Conditions?

Homeowners with rooftop solar installations can now apply for funding to purchase energy storage systems. Applications are being accepted starting October 20 under a new program by the National Fund for Environmental Protection and Water Management (NFOŚiGW), which has a total budget of 1 billion zloty. While the maximum subsidy available is 19,000 zloty, not all prosumers will qualify for the full amount. This article details the eligibility criteria for the program, the specific equipment covered by the funding, and key considerations to keep in mind before submitting an application.

Subsidies for residential energy storage systems

For years, solar panel owners have focused primarily on generating their own electricity. Today, the ability to store that power is gaining increasing importance. A battery system allows homeowners to use electricity at times other than when it is generated, such as in the evening when household demand rises and solar panels cease to produce. The “Subsidy for Home Energy Storage – Part 2” program, funded by the European Union’s Modernization Fund, is designed to support such investments.

Who is eligible to participate in the program?

The scheme targets prosumers, individuals who generate renewable energy primarily for their own consumption. Applicants must operate a grid-connected micro renewable energy installation and hold a valid contract with an energy company. Notably, the program is not restricted to participants in the newer settlement framework. Applications are accepted from prosumers operating under the net-billing system, where energy fed back into the grid is settled in cash, as well as those using the net-metering system, which relies on a discount mechanism. However, the chosen settlement method determines the maximum level of financial support available.

How much funding is available for energy storage?

Under the program, financial support for a home battery storage system can cover up to 30% of eligible expenditures. A further cap applies, limiting the subsidy to a maximum of 800 zloty per kilowatt-hour of device capacity.

For prosumers opting for net-billing, the maximum grant is set at 16,000 zloty. Those remaining in the net-metering system are eligible for up to 8,000 zloty.

The scheme also allows for subsidies of up to 1,000 zloty for heat storage units and up to 2,000 zloty for hybrid inverters. In both instances, the funding is restricted to equipment manufactured within the European Union.

The total assistance allocated to a single point of energy consumption cannot exceed 19,000 zloty. Consequently, the final grant amount is determined by a combination of factors, including the investment cost, device specifications, the chosen settlement method, and compliance with additional conditions.

Not every energy storage system qualifies for the subsidy

Buyers planning to purchase a home energy storage system should look beyond the price tag and focus on the device’s technical capabilities. The program sets a minimum capacity requirement of 10 kWh for electrical energy storage. Compatibility with an energy management system, or EMS, is equally critical. This solution allows users to control when energy is stored and when it is drawn from the system. Consequently, the device is not limited to merely acting as a buffer for surplus solar power. Another mandatory feature is the ability to power the home in emergency mode during grid outages. However, one should not assume that every storage unit on the market automatically provides this function, as the overall installation configuration plays a significant role.

“ These requirements protect buyers from storage systems that appear modern on paper but deliver little in practice. A 10 kWh capacity allows a meaningful portion of daily consumption to be shifted to the evening, rather than just powering lighting for a few hours,” said Mirosław Bieliński, co-founder of Pstryk and president of Bankilo Obrót. “The energy management system determines when the storage unit charges and when it discharges, so the actual amount of energy the device can provide depends on this system.”

The system will save money in the long run. Emergency power supply provides peace of mind during grid outages. Before purchasing, it is worth asking the installer three questions: how long the storage unit can power essential devices during a failure, whether the emergency mode is configured across the entire installation rather than just listed in the product datasheet, and whether the control system operates automatically without manual adjustments.

Purchases made before the application window opens may still qualify for funding

Although the application window opened on October 20, 2026, the funding is not limited to new purchases. The program also covers investments implemented from November 1, 2025, provided they meet all eligibility criteria. According to the schedule, the call for applications will remain open until October 1, 2027. However, the process may conclude earlier if the available budget is exhausted. Applications must be submitted online via the Funding Application Generator. Applicants are also required to prepare documentation confirming the execution of the investment and to satisfy the conditions regarding the connection of the installation to the grid. It is advisable to review the current list of required attachments on the program’s website before initiating the procedure. This step helps prevent delays in the review process caused by formal deficiencies.

Prioritize household energy requirements before selecting a storage unit

While the prospect of a grant can serve as a compelling incentive to purchase a storage system, it should not replace a thorough assessment of a household’s specific energy requirements. A home equipped solely with a photovoltaic array will have different needs compared to a building heated by a heat pump that also charges an electric vehicle. Priority should be given to analyzing the household’s total energy consumption, identifying peak demand periods, and determining what portion of current solar generation is being exported to the grid. The operational strategy for the storage unit is equally critical. Although the device can store self-generated solar power, it can also be configured to draw electricity from the grid during off-peak hours when rates are lower, then supply that energy to domestic loads later. Consequently, the overall return on investment depends not only on the initial purchase but also on the subsequent performance and configuration of the entire system.

The most effective starting point is reviewing the electricity bill from the previous year, and if the home is equipped with a remote meter, the hourly data provided by the network operator, according to Mirosław Bieliński. These records reveal how much energy the household consumes during the evening and winter months, which are precisely the periods when an energy storage system delivers the greatest value. A home relying solely on photovoltaics requires a different storage capacity than one equipped with a heat pump or an electric vehicle, where consumption can be several times higher. An undersized battery will deplete rapidly, while an oversized unit will never reach full utilization. The billing model also plays a critical role. Under net-billing, the value of energy fed back into the grid is tied to market prices, making it more economical to consume self-generated power during peak-rate hours rather than exporting it when rates are low.
