Share of renewable electricity generation Spain 2024, by type
In 2024, wind was the main source of renewable energy in Spain, representing roughly 41 percent of the electricity generation from renewable resources. Wind power capacity, together with solar photovoltaic, was the highest of all the renewable and non-renewable generation technologies, over combined cycle and hydropower plants. With over 32 gigawatts installed for each, wind and solar PV capacity accounted for half of the total power capacity.
Iberdrola leads in the wind energy field
In 2023, 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 2023.
Solar PV: fastest growing renewable in Spain
Although wind energy currently accounts for the largest share of renewable generation, solar photovoltaic energy is currently experiencing tremendous growth in Spain. From 2018 to 2024, the utility-scale solar photovoltaic capacity increased by some 28 gigawatts, roughly seven times the existing power in 2018. 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.
