Slovenia has launched a new financial support program aimed at accelerating investment in self-consumption solar power plants and electricity storage systems. Market operator Borzen has made 30 million euros in non-repayable funds available to eligible applicants.
The scheme targets solar installations with a capacity of up to 1 MW, along with associated battery storage units. Funding will be distributed on a first-come, first-served basis, and applications will open on 12 May. Submissions must be filed exclusively via Borzen’s online platform using a qualified digital certificate.
Eligible applicants include companies, cooperatives, self-employed individuals engaged in commercial activities, and local self-governing communities. However, only projects that received network connection approval after 1 January 2025 and began construction after that date will qualify for support. The financial aid is capped at 180 euros/kW of installed capacity, calculated based on nominal system or inverter power, and 225 euros/kWh of battery storage capacity. Total public support may not exceed 45% of eligible investment costs. The program operates under the de minimis rule, limiting total state aid to 300,000 euros per single undertaking over a three-year period.
To be eligible, installations must be connected under either the PS.3A or PS.3B schemes. The PS.3A model is typically applied to rooftop solar systems on commercial buildings and larger self-consumption facilities up to 1 MW, while PS.3B is more commonly used for community-based projects, shared generation arrangements, and specific metering configurations.
Projects awarded funding must enter operation within 18 months from the issuance of the grant decision. Following network connection, beneficiaries will have two months to submit a payment request. The final installed capacity may not deviate by more than 25% from the level approved in the decision. Once complete documentation is submitted, disbursement is expected within 60 days.
