May 6 (Renewables Now) - Spain’s power plants produced 46.2% of electricity with renewables in April, Spanish grid operator Red Electrica de Espana said in its latest estimates report.

The share of renewables in April’s total power production fell from 53.7% recorded a month earlier, which was then a decline from 58.9% in February, the figures show. REE highlights that April also saw an 11% increase in the production of “green gigawatt-hours” compared to the same time in 2020.

Nuclear power plants were the top electricity producers in April, generating 21.1% of the total output, followed by wind farms and combined cycle power plants. The solar power technologies -- photovoltaic (PV) and concentrated solar power (CSP) -- both ramped up output in year-on-year terms.

More details are given in the table below:

Technology: Share in April: Estimated production in April (in GWh): Y/Y change: January-April combined share:
Wind 20.8% 4,151 12.3% 26.5%
Hydro 13.4% 2,674 -6.6% 17.1%
Solar PV 8.2% 1,634 42.3% 5.9%
Solar CSP 1.4% 273 31.9% 1%
Other renewables 2.0% 396 17.3% 1.7%
Nuclear 21.1% 4,211 3.1% 21.3%
Cogeneration 11.1% 2,213 14.7% 10%
Combined cycle 17.2% 3,429 58.2% 11.3%
Coal 1.4% 274 -10.2% 1.4%

Spain’s demand for electricity in April was estimated at 19,973 GWh, up by 17.1% year-on-year. REE gave two sets of figures to illustrate the evolution of the demand –- those for April 2020, when Spain spent a full month sheltering in place to tame the spread of the COVID-19 pandemic, and those for April 2019.

Compared to April 2019, the nation’s demand for power decreased by 3.7%.

Demand figures for Spain’s three electricity systems separately are presented in the following table:

Territory Demand in April 2021 vs April 2020 vs April 2019
Mainland Spain 18,940 GWh +17.2% -3.1%
Balearic Islands 377,746 MWh +17.4% -17.1%
Canary Islands 624,641 MWh +13.9% -10.9%
