For the fourth year running, REE, the Spanish Electricity Grid, has published its report “Renewables in the Spanish electrical system”, which illustrates how these energies operated in 2019 and their evolution over recent years. At the end of 2019, Spain’s renewable stock amounted to 55,349 MW, generating a total of 97,888 GWh, almost 38% of the country’s total generation. This fall in renewable generation was caused by lower hydropower production (down 27.6%), the result of a year with less rainfall. The decline in production from coal-fired power stations (-66%) led to a considerable reduction in CO2 emissions.
The largest increase in installed renewable capacity of the last ten years took place in 2019, up almost 14% compared to the end of 2018 and representing an increase of 6,693 MW. For the first time since statistical records began, over half of Spain’s electrical power generation stock (50.1%) corresponds to renewables installations. This increase is mainly due to the increase in solar PV output, which accounted for 63% of the new capacity. The second source to have made the largest contribution to the new renewable capacity, although a long way behind, was wind power with an additional 2,254 MW.
The contribution of renewables to domestic electricity generation during 2019 was down slightly compared to the participation of the previous year, with a 37.5% share, compared to 38.4 % in 2018. Despite this decline, the weighting of renewable generation recorded the fifth highest figure of the last ten years.
