10 Jan 2022

The demand for electricity in Spain increased by 2.6% in 2021 to 256 TWh, according to the Spanish power transmission system operator Red Eléctrica de España (REE). Power generation increased by 3.4% to 260 TWh; spurred by a strong growth in wind (+10% to 60 TWh) and solar PV (+36.5% to 21 TWh), and a lower growth in CCGT generation (+1.5% to 45 TWh), while nuclear generation declined by 3% to 54 TWh and hydropower generation by 3.6% to 29.5 TWh. Overall, renewables accounted for nearly 47% of the country's power generation in 2021 (compared to 44% in 2020), with 23% of wind, 11% of hydro and 10% of solar. Including nuclear power (21%), the share of CO2-free power generation reached 68% of Spain's power mix.

Under the NECP 2021- 2030, renewables should cover 74% of power generation by 2030 and 100% in 2050.
