NFOŚiGW allocates 1 billion zł

Following the end of the Mój Prąd program, subsidies for solar panel owners are increasingly focusing on energy storage. NFOŚiGW is now launching the largest program to date specifically aimed at home energy storage systems. 1 billion zł from the Modernization Fund will be made available for this purpose.

The program is titled “Subsidies for Home Energy Storage – Part 2.” Applications can be submitted starting October 20 at 9:00 AM, exclusively electronically through the Subsidy Application Generator.

Up to 19,000 zł per energy consumption point, but...

The program is based on subsidies for electrical energy storage systems. Funding covers up to 30% of eligible costs, but there is also a limit of 800 zł per 1 kWh of nominal capacity.

For prosumers using net-billing, the maximum subsidy for the storage system itself will be 16,000 zł. For those still on the older net-metering system, the limit will be half of that, at 8,000 zł.

The amount of the subsidy depends both on the device’s price and its capacity. If someone buys a 10 kWh battery, the cap based on capacity is 8,000 zł, but it still cannot exceed 30% of the eligible costs. For an investment costing 25,000 zł, the subsidy would therefore be at most 7,500 zł.

Heat storage systems are also included in the program. Here, the support amounts to 30% of the costs, but up to a maximum of 1,000 zł. A hybrid inverter or a device with a similar function can also be subsidized if it is needed to enable the battery to work with renewable energy installations.

The total support for one Energy Consumption Point can reach 19,000 zł. This amount may consist of the maximum subsidy for an energy storage battery, support for a heat storage system, plus an additional bonus for devices manufactured in the European Union.

Major change: battery capacity of at least 10 kWh

The new program sets significantly higher capacity requirements than the previous Mój Prąd 6.0. In that program, the energy storage system had to have at least 2 kWh. Now, the minimum has risen to 10 kWh.

But that’s not all. The nominal capacity of the storage system must be at least twice the peak power of the connected photovoltaic installation.

For a 5 kWp installation, the required minimum will therefore be 10 kWh. For a 6 kWp photovoltaic system, it will be 12 kWh, while owners of a 10 kWp installation need a storage system with a capacity of at least 20 kWh.

This is an important rule because it can greatly affect the investment cost. NFOŚiGW aims to fund devices that are truly capable of storing a significant portion of the excess energy produced by home installations.

Mandatory EMS and home power supply during outages

Another difference from previous programs is the technical requirements.

The subsidized battery must work together with an Energy Management System (EMS). Such a system continuously decides where to direct the generated electricity—to household appliances, batteries, thermal storage, or the grid.

The second mandatory element is islanding capability. This refers to a situation where, in the event of a grid failure, a home can use energy stored in batteries.

Not every photovoltaic system with battery storage offers this automatically. A regular PV installation shuts down due to safety reasons when voltage drops in the grid. To ensure emergency power for a building, a properly configured battery storage system, inverter, and electrical installation are required.

An additional 2000 zł for devices from the EU

The program also includes a bonus for equipment of European origin. An additional amount of up to 2000 zł can be received for an energy storage system along with a corresponding inverter manufactured within the European Union.

For heat storage systems, the requirements are even more explicit—the subsidy will cover only devices produced in the EU.

For customers, this means that when choosing equipment, it’s not enough to consider only its capacity and price. Before purchasing, it is necessary to check the device’s origin, compatibility with EMS, island operation capability, and whether the capacity matches the power of the photovoltaic system.

It’s possible to claim reimbursement for investments started earlier

The application period starts on October 20 only, but that doesn’t mean devices can be purchased starting from that date.

Expenses incurred from November 1, 2025, are eligible. Thus, the program may cover some investments made even before its official launch, as long as the devices and documentation meet all requirements.

The application period is set to last until October 1, 2027, but there is one important condition: it can be closed early if the billion zloty budget is exhausted.

First My Electricity, then the transitional program

The new version represents another step in changes to subsidies for prosumers. For years, the main program has been Mój Prąd, which initially focused primarily on photovoltaic installations themselves.

Over time, devices that allow using the generated energy on site have become increasingly important. In the sixth edition of Mój Prąd, subsidies of up to 16,000 zł could be obtained for energy storage systems and up to 5,000 zł for heat storage systems. The electrical storage system had to have a capacity of at least 2 kWh, with the subsidy covering up to 50% of the eligible costs.

Interest was enormous. By the end of Mój Prąd 6.0 in September 2025, over 121,000 applications were submitted, totaling around 1.85 billion zł. There were approximately 74,000 applications specifically for home energy storage systems, with expected support in this area exceeding 1 billion zł.

After the end of Mój Prąd 6.0, “Subsidies for Home Energy Storage – Part 1” was launched. This was a transitional program funded by KPO, intended to fill the gap before the launch of the final system from the Modernization Fund.

The first application period ran from March 30 to May 8, 2026, and was later extended from June 8 to 19. By May 8, 12,738 applications had been submitted, using up 67.39% of the available funds at that time. When it was reopened, 105 million zł remained to be allocated.

Now it’s time for Part 2 – with a budget of 1 billion zł.

Subsidies shifting from panels to storage

A few years ago, the main goal was to increase the number of rooftop solar installations. Today, there are already many panels, and the bigger challenge has become utilizing energy as it is generated.

During sunny hours, thousands of installations simultaneously feed excess energy back into the grid, while households start drawing power again in the evening. Energy storage allows some of this excess to be saved for later use instead of being sold immediately.

This is particularly important for those on net-billing, which is why they are eligible for a maximum subsidy twice as high as that available to prosumers on net-metering.

According to government data, as of the end of the first quarter in 2026, there were already over 128,000 home energy storage systems in Poland. The national goal is to reach 200,000 devices by the end of 2027.

The new billion zlotys is set to significantly accelerate this process. However, this support is not a simple continuation of Mój Prąd. The subsidy covers only a smaller portion of the investment, the required storage space is much larger, and the device must meet additional requirements regarding energy management and emergency power supply for the home.
