Slovenia’s Ministry of Environment, Climate and Energy has launched a €29.5 million ($34 million) funding call to support new solar and wind energy projects, with or without battery storage, under its Renewable Energy Scheme Part A, co-financed by the European Union’s (EU) Modernisation Fund. 

The grant amount will cover up to 45% of the project cost for solar or wind energy installation. It will also provide up to 30% of the storage costs, only if it accompanies the eligible renewable energy project, provided that its capacity is at least 0.75 kWh per 1 kW of the nominal power of the project.

Funds will be available for use from fiscal years 2025 to 2029, or until the entire budget is exhausted. 

“The aim of the invitation is to support the installation of new or additional capacities for the production of electricity from renewable energy sources and thus exploit the potential of natural energy sources, with the aim of reducing greenhouse gas emissions to ensure a sustainable and reliable energy supply for the Republic of Slovenia,” stated the ministry.  

It launched the call on July 11, 2025, and will admit applications till January 7, 2026.  

Slovenia’s updated Integred National Energy and Climate Plan (NECP 2024), adopted by the government in December 2024, targets the reduction of GHG emissions by at least 55% by 2033 and accelerating the use of renewable energy sources in gross energy and end-use. Nuclear power continues to be part of the larger strategy.     

In 2023, Slovenia achieved a 25.07% share of renewable energy in its gross final energy consumption. In the electricity sector, the share of renewable energy reached 41.89% thanks to a surge in solar power generation, while it rose to 10.02% in the transport sector.  

At the end of 2024, Slovenia’s total installed solar PV capacity had reached 1.31 GW, according to the International Renewable Energy Agency (IRENA).
