Poland unveils new home storage subsidy 

Poland’s Ministry of Climate and Environment has announced a $257.9 million (PLN 1 billion) subsidy scheme for home battery and heat storage, aimed at increasing self-consumption from residential solar and other renewable energy installations.

The program is open to individuals with grid-connected home solar or other small renewable electricity systems. It will subsidize batteries with at least 10 kWh of capacity and heat storage tanks holding at least 100 liters. Batteries must provide at least 2 kWh of storage per kWp of the accompanying solar installation.

The scheme will cover the costs of purchasing and installing home storage systems. Battery grants will cover up to 30% of eligible costs, capped at approximately $206 (PLN 800) per kWh. Prosumers in the net-billing system can receive up to approximately $4,126 (PLN 16,000), while those in the net-metering system can receive up to approximately $2,063 (PLN 8,000).

Applicants can receive up to 30% of eligible costs for EU-manufactured heat storage systems, capped at approximately $258 (PLN 1,000). An additional bonus of up to approximately $516 (PLN 2,000) is available for an EU-manufactured battery or a necessary replacement EU-manufactured hybrid inverter. Total support is capped at approximately $4,900 (PLN 19,000) per electricity supply point.

The scheme is financed through the Modernization Fund. Applications will open on October 20 and close on October 1, 2027, or when funds are exhausted.

Poland’s Minister of Climate and Environment, Paulina Hennig-Kloska, said equipping residential solar installations with energy storage is a ministerial priority.

“The program has two main goals: increasing the efficiency of renewable energy use and strengthening energy security,” she added.

According to the ministry, the number of home energy storage systems in Poland rose from more than 10,000 in the first quarter of 2024 to around 150,000 in June 2026, supported by subsidies and market growth.

The ministry is targeting more than 200,000 home storage systems by the end of 2027.

Sławomir Ćwik, deputy minister of climate and environment, said eligible battery installations must include an energy management system and backup power capability.

“This allows households to maintain power even during grid outages,” Ćwik said.

An initial phase of support financed through Poland’s National Recovery Plan allocated approximately $28.9 million (PLN 112 million) to support the installation of more than 5,000 home battery systems, according to the ministry.

Poland’s Agency for Restructuring and Modernization of Agriculture recently announced a renewable energy subsidy scheme aimed at farmers. It opened for applications on October 5.

Following Australia

In Australia, the Federal government similarly offered a 30% subsidy on home installations of residential batteries, without a monetary or kWh cap, or need for existing solar installation, though some restrictions were added to cap the total installation sizing.

The scheme has been budgeted to approximately AU$7.2 billion (US$4.68 billion or PLN 18.15 billion), and has seen more than 500,000 households add storage, or some 13 to 14 GWh of behind-the-meter storage capacity.
