European Commission approves Slovenian state aid for grid battery storage

Funding to support 370 MWh of new BESS capacity in Slovenia has been approved under EU state aid rules, with €59 million expected to be disbursed before Dec. 31, 2030.

The European Commission announced on July 31 that Slovenia’s proposed BESS scheme can go ahead as it meets objectives set out under the EU Clean Industrial Deal, first adopted in June 2025.

State intervention in EU member state markets is subject to oversight from the European Commission, which enforces rules on market competition within the trade bloc. Slovenia’s new state aid scheme was found to be “necessary, appropriate and appropriate,” due to its potential to accelerate the transition toward a net-zero economy

The funding approval is the latest in a ramping up of investment in Slovenian BESS capacity in 2026.

The European Bank for Reconstruction and Development (EBRD) recently agreed to provide Slovenian developer NGEN Energetske Rešitve with a €70 million loan to support five BESS projects in Latvia, Poland, Romania, and Slovenia, while commercial and industrial developers in Slovenia can now apply for grants from a €10 million fund.

In a press release, Teresa Ribera, executive vice president for clean, just and competitive transition at the European Commission said the €59 million program will accelerate deployment of storage technologies in Slovenia and enable better integration of renewables with the country’s grid.
