Greece adds 340 MW of wind farms in 2025, acceleration seen for this year

New wind capacity came in at 340 MW in Greece last year, with 76 onshore turbines installed, according to the Hellenic Wind Energy Association (HWEA or ELETAEN).

Installations increased by 6.4% on an annual scale and represented EUR 420 million in investment. Total wind capacity reached 5,695 MW in the country, with HWEA expecting a 900 MW rise in 2026.

Papastamatiou: 2 GW await connection

Based on these numbers, the wind sector appears to be going through rebirth, after several years of low to average installations. Currently, 1.1 GW of new projects are under construction or contracted and the majority is expected to come online within the next 18 months.

Added on top are 200 MW from previous auctions, which took place during the period 2018-2022. HWEA said that even though 1,592 MW was awarded, only 852.4 MW managed to connect to the grid by the end of 2025.

“Right now, about 2 GW of wind farms have an installation license, but have not been completed. Half of those are under construction or contracted. There are also 3 GW who have completed environmental licensing and await grid connection terms. Naturally, there are even more projects that go through the licensing jumble. All of them – especially the most efficient – constitute national wealth and can reduce energy costs for consumers,” said HWEA’s General Director, Panagiotis Papastamatiou.

Terna Energy and Vestas top the charts

The top 5 operators by capacity in Greece are Terna Energy (18.2%), MORE (13.6%), Iberdrola Rokas (7.2%), Principia (6.5%) and PPC Renewables (5.6%).

Vestas has the highest share among manufacturers, 44%. Enercon accounts for 25%, followed by Siemens Gamesa with 15.8% and Nordex, which is at 9.2%.

Notably, the day with the highest hourly wind share in power production was April 28, 2025, when wind farms supplied 97.2%. In total, these units covered more than 50% of the demand for 616 hours of the year.
