PME grant for the battery
PLN 7,500
left to pay after the grant: PLN 17,500
| Battery: 30% of costs | PLN 7,500 |
| Cap PLN 800 per kWh | PLN 8,000 |
| Cap per battery | PLN 16,000 |
| Price per kWh (cap PLN 3,000) | PLN 2,500 |
| Heat store: 30%, up to PLN 1,000 | PLN 0 |
| Total grant | PLN 7,500 |
PME part 2 (Modernisation Fund) runs from 20 Oct 2026 to 1 Oct 2027 and covers purchases from 1 Nov 2025. Up to PLN 2,000 extra for an EU-made hybrid inverter or battery.
The price of a home battery depends on capacity, technology and installation scope, and there is no official average. There is an official ceiling, though: under the Przydomowe Magazyny Energii programme a battery may not cost more than PLN 3,000 per kWh of capacity excluding the inverter and energy management system, or no grant is paid. The grant itself is 30% of costs, at most PLN 800 per kWh and PLN 16,000 under net-billing or PLN 8,000 under net-metering. A 10 kWh battery costing PLN 25,000 therefore gets PLN 7,500 and costs PLN 17,500 after the grant. In a Warsaw house with a 6 kWp system and 4,000 kWh of use, such a battery raises the yearly saving by about PLN 897, so your share pays back in 19.5 years. The part 2 call runs until 1 October 2027. The calculator above checks the conditions for your quote.

| Battery and price | Per kWh | PME grant | After grant | Payback of share |
|---|---|---|---|---|
| 10 kWh, PLN 20,000 | PLN 2,000 | PLN 6,000 | PLN 14,000 | 15.6 years |
| 10 kWh, PLN 30,000 | PLN 3,000 | PLN 8,000 | PLN 22,000 | 24.5 years |
| 15 kWh, PLN 36,000 | PLN 2,400 | PLN 10,800 | PLN 25,200 | 28.1 years |
| 20 kWh, PLN 45,000 | PLN 2,250 | PLN 13,500 | PLN 31,500 | 35.1 years |
| 20 kWh, PLN 65,000 | PLN 3,250 | none (price > PLN 3,000/kWh) | PLN 65,000 | 72.4 years |
The last row shows the most common trap: a battery costing more than PLN 3,000 per kWh loses the whole grant, not just the excess over the cap. Payback is longer for large batteries, because the house uses a limited amount of energy in the evening and at night.
