Greece’s total installed wind power capacity reached 6,017 MW by the end of the first half of 2026, according to the latest biannual statistical analysis published by the Hellenic Wind Energy Association (HELWEA). This marks a 5.6% increase compared to the end of 2025.
New Installations in Early 2026
In the first six months of 2026, 65 new wind turbines were connected to the national electricity grid, adding 320.6 MW of nameplate capacity. These projects represent approximately €400 million in investment — nearly matching the total wind capacity commissioned across all of 2025. The association describes this as a positive sign of sector resilience amid persistent regulatory and bureaucratic challenges.
Projects Under Construction
As of mid-2026, around 700 MW of new wind farms were under construction. The vast majority are expected to be grid-connected within the next 18 months, pushing Greece’s total wind capacity beyond 6.5 GW by late 2027.
Regulatory Bottlenecks Persist
Despite the growth, the report notes a slowdown in new construction starts compared to the previous semester — reinforcing concerns that Greece’s project development and licensing framework requires significant reform.
Regional Distribution
By region, Central Greece remains the leading hub for wind energy, hosting 2,603 MW (43.3%) of the national total. The Peloponnese follows with 819 MW (13.6%), and Eastern Macedonia–Thrace accounts for 535 MW (8.9%).
Top Developers
The top five corporate groups by installed capacity are:
- Terna Energy: 1,040.3 MW (17.3%)
- MORE: 796.4 MW (13.2%)
- Principia: 514.1 MW (8.5%)
- Iberdrola Rokas: 409.2 MW (6.8%)
- DEH Renewables: 319.2 MW (5.3%)
Other active investors include Quantum Energy Partners, EDF, TotalEnergies, METLEN, Jasper Energy, and Cubico.
Turbine Suppliers
Vestas supplies the largest share of installed wind capacity in Greece (43.1%), followed by Enercon (23.6%), Siemens Gamesa (15.0%), Nordex (12.2%), and GE Renewable Energy (4.1%). Smaller shares belong to Goldwind, EWT, Leitwind, and Vensys.
In the first half of 2026, Nordex supplied the majority of newly installed turbines (207.2 MW, or 64.6%), followed by Vestas (88.2 MW, 27.5%) and Goldwind (25.2 MW, 7.9%).
Auction-Based Projects
Between 2018 and 2022, the Regulatory Authority for Energy (RAE) awarded wind farm projects totaling 1,592 MW through competitive tenders. However, due to administrative delays, only 1,191 MW — about 75% — had been commissioned by mid-2026.
