Share of electricity generation in Spain 2023, by source

The Spanish grid was mainly powered by wind and nuclear power plants in 2023. With a share of 23.5 percent, wind turbines were the most commonly used electricity generation technology in Spain that year, followed closely by nuclear power, which took up approximately 20.3 percent of the grid. Ranking also as an important energy generation source, combined cycle power plants held a share of 17.3 percent. In contrast, waste-to-energy sources accounted for roughly one percent of the grid.

Wind and nuclear power in Spain

In 2023, the main source of electricity in Spain was wind energy with a generation of approximately 62.6 terawatt hours. Wind power led the list of the largest installed capacity of energy sources in that year with over 30 gigawatts installed. Nuclear power generation clocked up approximately 54 terawatt hours in 2023.

Electricity production from renewable sources

During 2023, roughly half of the energy generated from renewable sources came from wind power. Electricity generation from solar photovoltaics represented almost 30 percent of all the electricity generated that year through renewable sources, making it the second most common on the list. Due to the large capacity for renewable energy installed in the region, Castile and Leon topped the list of autonomous communities with the highest generation from renewable sources in 2022, with 20.7 terawatt hours.
