Just 152.2 MW of wind farms were installed in Greece in the first half of 2025, thus continuing the low trajectory of recent years.

According to the Hellenic Wind Energy Association (HWEA or ELETAEN), total wind capacity in the country reached 5,507 MW at the end of June. In the first six months of the year, 37 new wind turbines were installed in Greece, with a capacity of 152.2 MW, representing a total investment of EUR 180 million.

New capacity doubled compared to the same period of 2024, but is not enough to support a more balanced renewable mix, HWEA said. In comparison, photovoltaics consistently add similar capacity in just one month on average.

The association also mentioned that currently there is 1 GW of wind projects under construction, or contracted. The majority are expected to launch operations within the next 18 months. There is another 300 MW selected through auctions for which letters of guarantee were submitted, and it is expected to reach completion. As a result, total capacity is projected to reach 6.5 GW within the period.

HWEA: Red tape is delaying 846 MW of wind projects

HWEA stressed that due to red tape, the construction of over half of the wind power capacity awarded at renewable energy auctions in the period 2018-2022 has been delayed. Namely, 1.592 MW was selected, but just 746 MW is operational today.

“If they had been completed on time, these wind projects, with a total capacity of 846 MW, would have provided more cheap energy and permanent relief to Greek consumers and the national economy,” HWEA pointed out.

Terna Energy and Vestas lead the pack

When it comes to wind energy’s geographical dispersion, Central Greece (Sterea Ellada) leads with 2.427 MW, followed by 709 MW in the Peloponnese and 535 MW in Eastern Thrace.

The top 5 market players are Terna Energy (1,034 MW – 18.8%), owned by Masdar, Motor Oil Hellas’s subsidiary MORE (774 MW – 14.1%), Iberdrola Rokas (409 MW – 7.4%), Principia (368 MW – 6.7%) and PPC Renewables (308 MW – 5.6%), which operates within state-controlled Public Power Corp. or PPC).

The most prominent wind turbine suppliers are Vestas, with 45.1% of the market, followed by Enercon, with 25.7%, and Siemens Gamesa, with 16.4%. They are trailed by Nordex, with 7.6%, GE Renewable Energy (now GE Vernova), with 3.7%, and EWT, Goldwind and Leitwind.
