Following a difficult year in 2024, Greece’s wind energy sector is experiencing a resurgence in 2025, characterized by new capacity additions that align with historical growth rates. This rebound signals a revitalization of investments in one of the nation’s pivotal renewable energy sources.
Data from the Hellenic Wind Energy Association (ELETAEN) reveals that 76 wind turbines were integrated into the national grid in 2025, contributing an additional capacity of 340 MW. This development represents investments exceeding 420 million euros and marks a notable increase of 6.4% in newly installed capacity compared to the previous year. As of the end of 2025, Greece’s cumulative operational wind capacity reached approximately 5.7 GW.
The outlook for further growth appears promising, with over 1.1 GW of wind projects either under construction or contracted at the close of 2025, anticipated to be completed and connected to the grid within the next 18 months. Additionally, around 200 MW of capacity awarded through competitive tenders is expected to advance, supported by performance guarantees despite not being part of the primary construction pipeline.
If these developments proceed as planned, projections indicate that Greece’s installed wind capacity could exceed 6.5 GW within the upcoming year and a half, thereby enhancing the significance of wind power within the national electricity framework.
However, despite this positive trajectory, systemic challenges continue to hinder sector expansion. ELETAEN has identified ongoing administrative and permitting delays as significant barriers to project implementation. Between 2018 and 2022, regulatory authorities selected a total of 1,592 MW of viable wind projects through competitive auctions; yet only about 852.4 MW—slightly over half—have become operational thus far.
These delays underscore persistent bottlenecks in licensing and network connection processes that remain critical obstacles for developers. While the year 2025 has marked a significant recovery for Greece’s wind energy sector, future advancements will hinge on addressing bureaucratic challenges to ensure timely delivery of both awarded and contracted projects.
