Following a difficult year in 2024, Greece’s wind energy sector has begun to stabilize and grow in 2025, reflecting a return to the average capacity addition rates observed over the last decade. This resurgence is underscored by renewed investment activity, which is critical for the advancement of renewable energy technologies in the country.
Data from the Hellenic Wind Energy Association (ELETAEN) reveals that 76 wind turbines were integrated into the grid in 2025, contributing an additional capacity of 340 MW. These developments represent investments exceeding 420 million euros and signify a 6.4% increase in newly installed capacity compared to the previous year. As a result, Greece’s total operational wind capacity reached approximately 5.7 GW by the close of 2025.
The growth momentum is anticipated to continue, with over 1.1 GW of wind projects either under construction or contracted at the end of 2025 expected to be completed and connected to the grid within the next 18 months. Additionally, around 200 MW of capacity awarded through competitive tenders, supported by performance guarantees, is also projected to advance, even though it does not form part of the primary construction pipeline.
If these initiatives proceed without major setbacks, Greece’s installed wind capacity could exceed 6.5 GW within the upcoming year and a half, further enhancing the significance of wind power in the national electricity landscape.
Despite this positive outlook, several structural challenges persist within the sector. ELETAEN has highlighted ongoing administrative and permitting delays that hinder project execution. Between 2018 and 2022, regulatory bodies identified 1,592 MW of viable wind projects through competitive auctions; however, only about 852.4 MW—just over half—have become operational thus far.
These delays point to persistent bottlenecks in licensing and network connection processes that remain critical obstacles for developers. While the year 2025 has marked a significant rebound for Greece’s wind energy industry, future advancements will hinge on addressing bureaucratic challenges to ensure timely delivery of both awarded and contracted projects.
