Twenty-five municipalities and public institutions from across Slovenia have completed a project to deploy 87 solar power plants for self-consumption, with a combined installed capacity of more than 6.3 MW. The project, aimed at fostering the public sector’s energy independence, also included the installation of a 232 kWh battery energy storage system.
The 87 solar power plants, installed on public buildings and at parking lots, are expected to generate around 6.6 GWh of electricity annually, equivalent to the consumption of about 1,700 households. All installations are expected to be commissioned by the end of July, Naš stik reported.
The solar power plants are projected to generate 6.6 GWh a year
The project was supported by the Ministry of Infrastructure and Energy and the European Union through the National Recovery and Resilience Plan.
It was carried out by two consortia of municipalities and public institutions. The overall investment amounted to about EUR 6.5 million, with EUR 4.5 million coming from EU funds.
The first consortium installed solar power plants totaling around 3.9 MW at 53 locations, while the second added just over 2.4 MW at 34 locations.
Construction took place between October 2025 and May 2026, with the Municipality of Ravne na Koroškem coordinating the effort. In Ravne na Koroškem, solar power plants were installed on 13 buildings, including a health center, schools, and the local sports center.
Public institutions are expected to cut electricity costs
At the project’s closing ceremony, Tomaž Rožen, mayor of Ravne na Koroškem, said the participating partners are expected to benefit from lower electricity costs. The electricity generated will primarily be used by the buildings where the solar power plants are installed, as well as by other public facilities within the same municipality.
The event also included a ribbon-cutting ceremony for the 232 kWh battery energy storage system.
Slovenian consultancy Eutrip managed, coordinated, and supervised the entire project.
Eutrip noted that the project demonstrates how joint efforts can help accelerate the public sector’s transition towards energy independence.
