Is Greece ready for a battery energy storage system in 2025?

In 2025, Greece has accelerated its plans for utility-scale Battery Energy Storage Systems (BESS), signalling a shift in policy, financing, and market expectations. However, while the scale of ambition is high, there are several tensions emerging—especially around the move toward unsponsored (merchant) projects.

Does Greece have a battery storage subsidy program?

Greece’s latest auction has awarded subsidies to 188.9 MW of standalone, front-of-the-meter, utility-scale battery energy storage. The auction was the third and final edition of a battery storage subsidy program launched in 2023, with the country now turning its focus towards a new 4.7 GW unsibsidized BESS scheme.

What does the new Bess regulatory framework mean for Greece?

As Greece continues to accelerate its energy transition, the new BESS regulatory framework is a crucial step forward in the country''s efforts to modernise and decarbonise its energy sector.

What are the challenges faced by Bess developers in Greece?

Beyond financing, regulatory and grid-related bottlenecks pose further challenges. Although Greece has established a comprehensive policy framework for BESS, developers report that environmental permitting, connection approvals, and the physical capacity of the grid remain major obstacles.
