Slovenian energy market operator Borzen has launched a new funding scheme aimed at accelerating the deployment of battery energy storage systems (BESS) among businesses and public-sector organizations. The program provides a total of 10 million euros in non-repayable grants, designed to support investments that improve energy efficiency, enhance system flexibility, and strengthen energy independence.
Under the initiative, eligible applicants can receive financial support covering up to 45% of total eligible project costs, with funding capped at 225 euros/kWh of installed storage capacity. This level of support is intended to significantly reduce upfront investment barriers for organizations adopting modern energy storage technologies.
The scheme is open to legal entities and public institutions, while excluding direct beneficiaries of the state budget. It supports newly installed battery storage systems, hybrid inverters, and related electrical infrastructure required for operation. Importantly, the program is retroactive in nature, meaning it reimburses already completed projects rather than future investments.
To qualify, energy storage systems must have been connected to the electricity grid between 1 January and 31 July of this year. Applicants must also hold a valid grid connection approval issued after 1 January 2024. Eligible expenses include investments made from 1 October 2025 onward, allowing companies that recently completed storage installations to recover part of their costs through this support mechanism.
Borzen stated that the program is designed to encourage wider adoption of clean energy technologies, reduce dependence on fossil fuels, and improve the competitiveness of Slovenian businesses through smarter energy management. By promoting battery storage deployment, authorities also aim to increase grid flexibility and enable smoother integration of higher shares of renewable energy sources into the electricity system.
