Share of renewable electricity generation Spain 2023, by type

In 2023, wind was the main source of renewable energy in Spain, representing roughly half of the electricity generation from renewable resources. In fact, the wind power capacity installed in the country was the highest of all the renewable and non-renewable generation technologies, over combined cycle and solar photovoltaic plants. With over 30 gigawatts installed, wind power capacity was close to a quarter of the total power capacity.

Iberdrola leads in the wind energy field

In 2022, the main developer of wind energy in the country was Iberdrola, one of the largest electricity companies in Spain, with an installed wind power capacity of more than six gigawatts. Acciona Energy followed with approximately 4.1 gigawatts installed. Endesa, another of the main Spanish electricity suppliers, was in third place with 2.7 gigawatts. The Spanish wind sector had more than 22,000 wind turbines installed as of end of 2022.

Solar PV: fastest growing renewable in Spain

Although wind energy currently accounts for the largest share of renewables, solar photovoltaic energy is currently experiencing tremendous growth in Spain. From 2018 to 2023, the installed solar photovoltaic capacity increased by some 20 gigawatts, more than quadrupling the existing power at the time. The renewable auctions planned by the government will award at least 1.8 gigawatts of solar photovoltaic energy per year from until 2026. It is forecast that by 2050, the capacity of solar energy will reach 62.4 gigawatts, while that of onshore wind will stand at 52.4 gigawatts.
