Wind Energy in Greece

2021 wind energy numbers

The total installed wind power capacity in Greece at the end of 2021 reached 4456 MW (an 8% increase compared to the end of 2020).

The total new capacity installed in Greece in 2021 was 338 MW lower than the all-time record of 2019 (752 MW) but still higher than the 10-year average (284 MW). A total of 128 new wind turbines with an average nameplate capacity of 2.67MW were installed.

Aside from natural gas, wind energy remains the biggest domestic energy source for the Greek Electricity system, providing 18.9% of total demand. During the year, variable RES penetration to the electricity system reached values as high as 92% of total demand (1-hour average), without any negative side effects on the operation and stability of the system.

To read more about the wind energy sector in Greece, please review their chapter in the 2021 Annual Report.



Total wind power capacity is 4,450 MW.


Wind power capacity in Greece increased by 340 MW in 2021.


Greece produces 10.5 TWh from wind energy, which accounts for 18.9% of the country’s electricity consumption.

National Targets

The National target for renewable energy for 2030 as set in the National Plan for the Energy and the Climate foresees 66% RES share in electricity production by 2030. To achieve this target, an estimated total wind capacity of 7000 MW is needed by the end of 2030. Such a target would require a mean annual installation rate of 250-300 MW per year, comparable to the average rate of new installations achieved in the last three years. A strong political will exists within EU countries to accelerate the transition to a 100% carbon-free electricity system. However, this has not yet been depicted as concrete new targets.

Progress & Operational Details

During the year, non-dispatchable RES (wind, solar and small hydro) penetration to the electricity system reached high values. Maximum 1-hour averaged wind energy penetration on the main electricity grid was 73.5% (October 25th, 03:00-04:00), while on the same day, maximum day-averaged wind penetration of 52.5% was achieved. Maximum 1-hour average penetration for all non-dispatchable RES reached an impressive 92.1 % on October 28th. Throughout the year, the central electricity system of Greece operated with non-dispatchable RES penetration exceeding 50% for 851 hours without any problem. The total value of new wind capacity set in operation within the year in Greece is estimated to be 340mio euros. By the end of 2021, 650MW of new wind energy plants were under construction, most of which are expected to be operational within the next 18 months.

National RDD Priorities and Budget

Greece’s R&D activities in wind energy are funded mainly through EU and national programs. Due to the pandemic situation, no new funding schemes for wind energy projects were launched in Greece. Delays were also experienced in contract signing and fund flow for projects approved in the previous year. A non– exhaustive review of R&D proposals oriented mainly in wind energy that were granted funding in 2021 revealed two new projects with a total budget of 1.95mio euros, which were awarded under the Program for Research, Technological Development and Innovation “EREVNO” (co-funded by the Greek state and the European Regional Development Fund).
