Greece installed around 1.9 GW of new solar capacity in 2025, bringing total installed solar capacity to roughly 11.5 GW, according to industry estimates.
Investors have submitted applications for 12.15 GW of utility-scale, standalone merchant battery storage projects in Greece, far exceeding the 4.7 GW the country plans to approve. But with wrestling over financing and key policy details still unresolved, the path to construction remains unclear.
Greece’s solar producers are facing rising curtailments that are cutting revenues and driving interest in energy storage, even as regulatory and financing challenges slow deployment.
Greece’s distribution grid operator will begin accepting applications for agrivoltaic systems on March 4, marking the first step in implementing a new law targeting 130 MW of capacity nationwide.
Greece’s energy regulator has launched two new auctions under the Apollo Program, covering up to 200 MW of solar with storage and a separate 400 MW wind tender, marking the scheme’s first operational rollout since becoming law in 2024.
Self-consumption PV projects accounted for most of the new solar capacity added in Cyprus last year, despite record levels of renewable energy curtailment, according to industry data.
Cyprus wasted nearly half of its distributed renewable generation in 2025, equivalent to 306 GWh, as grid constraints and lack of battery storage forced massive curtailments while solar capacity keeps growing.
Greece has awarded permits for about 900 MW of standalone, front-of-the-meter battery storage through three auctions, but no projects have yet been connected to the grid.
Two complaints to the European Commission allege Greek repowering policies and high performance bonds for battery storage projects block upgrades, raise costs, and hinder energy transition, according to industry association Pospief.
Cyprus will replace its current net metering and billing schemes with a new, market-based self-consumption model from January 2026, as the island’s electricity sector opens to competition.
