Greece is set to miss its 2030 wind capacity target even after accelerating wind-power construction in the first half of 2026, according to projections contained in the document. Developers commissioned 321 MW of wind capacity in the first six months of the year, more than double the 152 MW added in the same period of 2025. Installed operating wind capacity rose to 6.017 GW at the end of June.
WindEurope projections cited in the document expect around 450 MW to be commissioned in 2026. The outlook also calls for 430 MW in 2027 and 400 MW in 2028, followed by around 350 MW each year in 2029 and 2030. Based on that commissioning path, Greece would reach about 7.65 GW of wind capacity by 2030.
The projected level would be around 1.25 GW below the 8.9 GW target included in Greece’s National Energy and Climate Plan. All of the projected additions are expected to come from onshore wind.
Onshore wind commissioning outlook through 2030
The document’s commissioning schedule indicates a sustained buildout after the first half of 2026. It places total operating capacity at about 7.65 GW by 2030, using annual commissioning figures of 450 MW, 430 MW, 400 MW, and around 350 MW. The onshore-only assumption applies to the entire projected period.
The gap to the National Energy and Climate Plan target remains tied to the pace implied by those projections. With Greece’s operating base at 6.017 GW at end-June, reaching 8.9 GW would require additional capacity beyond what is forecast for 2026-2030.
Status of offshore wind projects and permitting progress
The projections indicate offshore wind is further behind than onshore development. They do not expect Greece to have commercial offshore wind capacity operating by 2030, even though the country has set a goal of 1.9 GW by 2032. Two pilot projects in the northern Aegean with combined planned capacity of 600 MW have been cancelled.
Despite those cancellations, Greece has reserved 2.35 GW of grid capacity for initial offshore projects. Permitting for wind projects has also advanced slowly, with authorities approving 214 MW during the first half of 2026 compared with 206 MW approved a year earlier.
The document’s figures imply that closing the shortfall toward the 2030 target would require faster permitting and a stronger onshore development pipeline. It also indicates offshore projects would need to accelerate considerably to contribute materially early in the next decade, given the lack of commercial offshore capacity expected by 2030.
