Last week, Slovenia announced a public call for non-repayable financial aid to support the procurement and installation of battery storage units for existing solar power plants used for self-supply. The total funding available for this initiative is €8 million.
Eligible applicants can receive financial aid of €275 per kWh of storage capacity, covering up to 40% of the eligible investment costs. The aid is limited to a maximum capacity of 2 kWh per installed kW for self-sufficient power plants, with a cap of 27.2 kWh per connection point. While there is no upper limit on battery storage capacity, it must be at least 0.7 kWh per installed kW for self-supply plants.
The non-repayable aid will be allocated for investments in battery systems connected to the low-voltage network of facilities that already have functional self-supply devices. Applicants must be registered as end customers of self-supply by the distribution operator and have signed a system usage agreement.
The financial aid is available for new investments in energy storage units made after January 1 of this year, but purchases of used, refurbished, pilot, or prototype battery storage units are not eligible. Applications for the financial aid can be submitted starting October 1 at Borzen.
