With the addition of 3.36 GW new solar power capacity in 2021, Spain's cumulative installed capacity of this clean power generation resource at the end of last year exceeded 15 GW, according to the country's national electricity grid operator Red Electrica de Espana (REE).
This is higher than the REE's previous estimate of 2.3 GW new solar capacity addition in 2021 (see Spain Installed 2.3 GW New Solar In 2021).
According to REE, this is a growth of 28.8% over 2020 when the annual additions were counted as 2.93 GW, expanding its electricity production to increase by 36.7%. In all, renewable power generation capacity additions in 2021 were over 4 GW taking cumulative to 63.89 GW. This represents 56.6% of the national power generation capacity of 112.84 GW.
In comparison, aggregate wind power generation capacity of the country as of 2021-end was 28.17 GW, and that of combined cycle was 26.25 GW, hydroelectric 17.09 GW, among others.
