Technical FAQs 4

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.

Does Greece have a zero-subsidy battery system?

The much-awaited ministerial decree for zero-subsidy standalone battery systems has been published in Greece. So far, Greece has provided support to 900 MW of standalone storage projects under three previous auctions.

Is Greece at a turning point with battery energy storage?

Greece in 2025 is at a turning point with Battery Energy Storage. The government’s shift toward large unsponsored, merchant BESS with priority grid connection reflects confidence that market conditions — especially curtailment pressures — are making subsidised models less necessary. Yet that confidence comes with risk.
