Greece Wind Energy Market Size, Share and Outlook - Growth Analysis Report and Forecast Trends 2026-2030

Greece's wind energy sector represents a mature and expanding segment of the country's renewable energy portfolio, with total installed capacity reaching 5.70 gigawatts in 2025. The market operates within the broader European context, where wind power led new renewable installations in 2025 with onshore projects comprising approximately 90 percent of the continent's 19.1 gigawatts of new capacity. Greece's geographic position in the Mediterranean provides strong and consistent wind resources, particularly across the mainland regions of Evia, Thessaly, and Sterea Ellada, as well as emerging opportunities in the Aegean islands.

• •Installed wind capacity in Greece reached 5.70 GW in 2025
• •Projected to grow to 8.75 GW by 2030 at a CAGR of 8.95%
• •Onshore wind accounts for the majority of Greece's current wind installations

The expansion of Greece's wind energy market is anchored in the country's commitment to achieving carbon neutrality by 2050, aligned with the European Union's binding renewable energy targets and climate legislation. Greece's diverse topography, including mountain ranges, coastal areas, and island territories, provides exceptional wind resources that support both utility-scale onshore projects and emerging offshore developments. Government policies including competitive auction schemes, streamlined permitting processes, and grid access guarantees have created an attractive investment environment for both domestic and international developers.

• •EU renewable energy mandates and national decarbonization targets driving deployment
• •Favorable wind resource conditions across mainland and Aegean island regions
• •Supportive regulatory frameworks including auction-based tenders and permitting reforms

The Greece wind energy market is overwhelmingly onshore-focused, consistent with the European trend where approximately 90 percent of new wind capacity installed in 2025 was land-based. Primary development corridors include Central Greece, Thessaly, and the Peloponnese, where consistent wind patterns support utility-scale installations ranging from 20 to 200 megawatts per project. Offshore wind represents an emerging segment with substantial long-term potential in the Aegean and Ionian Seas, though deployment remains limited compared to Northern European markets.

• •Onshore wind dominates current installations across mainland regions
• •Key development zones include Evia, Thessaly, and Central Greece
• •Aegean Sea offshore wind holds significant untapped potential for future expansion

What are the recent trends and outlook?

Greece's wind energy sector is positioned for sustained growth through 2030, supported by the national Energy and Climate Plan targeting a renewable energy share exceeding 60 percent in electricity consumption. Hybrid renewable projects combining wind generation with solar photovoltaic capacity and battery energy storage are emerging as a dominant development model, particularly for island grids pursuing energy independence from mainland supply. The anticipated opening of offshore wind tender rounds and ongoing investments in grid infrastructure modernization are expected to unlock additional capacity, positioning Greece to approach its 8.75 gigawatt target by the end of the decade.

• •Hybrid wind-solar-storage projects gaining momentum for island and mainland applications
• •Offshore wind tender processes expected to accelerate deployment through 2030
• •Grid infrastructure upgrades planned to support increased renewable energy integration
