As of December 31, 2022, the power generation fleet of the Spanish electricity system, which includes the peninsular system and non-peninsular systems, had increased by 4.9 % compared to the previous year, reaching an all-time high with an installed power capacity of 119,091 MW.

Installed renewable power capacity in the Spanish electricity system increased by 4.9 GW in 2020 and by 4.6 GW in 2021. Additionally, the installed renewable power capacity has increased by an additional 5.9 GW in 2022, which has led to an installed renewable power capacity of 70.5 GW in the Spanish electricity system. This represents a total installed power capacity of 59.2 %. The integration of this new renewable capacity, mostly wind and solar photovoltaic, represents a strong boost to the energy transition and to the fulfilment of the integration roadmap set out in Spain’s National Energy and Climate Plan (NECP), with a 2030 horizon.

The electricity system on the Spanish peninsula is also becoming increasingly cleaner, as there was a 9.1 % increase in installed renewable power capacity in 2022 compared to the previous year.

The 4.9 % increase in installed wind power capacity in 2022 is particularly noteworthy, making it the generation technology with the highest rate of installed capacity on the peninsula, with a total of 29,417 MW, representing more than a quarter of all installed power capacity in the peninsular electricity system.

Over 2022, installed solar photovoltaic power capacity saw the greatest increase in the peninsular electricity system, adding around 4,400 MW to the generation fleet. During 2022, solar photovoltaic power has managed to overtake hydropower and is currently the third largest generation source in the ranking, accounting for 17.0 % of the total installed capacity on the Spanish peninsula.

On the contrary, non-renewable peninsular power capacity fell by 0.8 %, mainly as a result of the 8.5 % reduction in installed coal power capacity due to the definitive decommissioning of the 300 MW Puente Nuevo plant located in Espiel (Córdoba) in August, following the drafting of the closure certificate.

As a result, by the end of 2022, coal accounted for 2.8 % of total peninsular installed power capacity, compared to its 3.3 % share in 2021, and ranked eighth in the structure of the generation fleet.

In the non-peninsular systems, there was an increase of 2.2 % in installed power capacity by the end of 2022. This increase is mainly explained by the 2.4 % growth in installed wind power capacity and 31.4 % in solar photovoltaic with respect to 2021.

The generation fleet of the Balearic Islands electricity system has experienced a 3.5 % increase in installed power capacity in 2022, owing to the 37.3 % increase in installed renewable power capacity. At the end of 2022, installed renewable power capacity accounted for 12.6 % of the generation fleet in the Balearic Islands, thus doubling the share it had in 2019. Installed solar photovoltaic power capacity in the Balearic Islands has grown to 225 MW from 152 MW in 2021, representing an increase of 47.9 % over the year 2022.

In the Canary Islands, the installed renewable power capacity has increased from 757 MW to 802 MW in the last year, which represents an increase of 6.0 %. This growth has meant that the installed renewable power capacity in the Canary Islands accounted for a quarter of the total Canary Islands generation fleet by the end of 2022. Specifically, the increase in installed power capacity has occurred in wind power with a growth of 2.4 % and in solar photovoltaic with 17.5 %.

Installed solar photovoltaic power capacity in the Canary Islands has grown from 181 MW in 2021 to 212 MW in 2022 and is the sixth largest source of generation in the Canary Islands' mix. At December 31, 2022, solar photovoltaic power capacity represented 6.6 % of the installed capacity in the island system (5.7 % in 2021).

The most relevant aspects of the installed power capacity by autonomous communities in 2022 include the following:

  • In 2022, Andalusia was the third community with the highest installed renewable power capacity in Spain, with a total of 9,811 MW of green power, surpassed only by Castile and Leon and Castile-La Mancha. Thus, 55.5 % of the Andalusian generation fleet is renewable. During 2022, Andalusia was the second community with the greatest increase in solar photovoltaic power capacity, adding 1,123 MW of new capacity and accounting for 21.0 % of the national total. Consequently, solar photovoltaic has become the second technology in the Andalusian generation fleet, with a share of 23.6 %. In addition, 300 MW of coal have been decommissioned.
  • In Aragon, renewable energies now represent 75.6 % of the total installed power capacity. It was the second community with the largest increase in wind power capacity in 2022, with an increase of 352 MW, which meant that wind power continues to be the leading technology in Aragon's mix, accounting for 46.2 % of installed power capacity.
  • In Asturias, the installed renewable power capacity, which reached 1,595 MW at the end of the year, increased by 2.6 % in 2022 due to the addition of 40 MW of new wind power capacity.
  • Castile-La Mancha has been the region where more renewable power capacity has been installed in 2022, with a total of 1,619 MW of new capacity, reaching the second position in the ranking of installed renewable power capacity (9,865 MW), only surpassed by Castile and Leon. Besides, it is the region with the second largest share of renewable power capacity in our country, accounting for 14.0 % of the total installed power capacity in Spain. This growth in renewables can be attributed, on the one hand, to the installation of 553 MW of wind power capacity in 2022, marking the largest increase in this technology in the whole country. In addition, solar photovoltaic, with 1,066 new MW installed in 2022, is the technology that has experienced the greatest share increase in La Mancha's generation fleet, 35.7 % more than in the previous year.
  • Castile and Leon continues to record the highest figures for installed renewable power capacity in Spain, with 12,554 MW, representing 95.6 % of its generation fleet. This community accounts for 17.8 % of all renewable power in the Spanish electricity system. Wind power, with a share of 50.4 % of the total, is the technology with the greatest presence in the region, and solar photovoltaic is the one that has registered the greatest increase, putting into service 404 new MW (more than double the amount in 2021) and increasing its generation capacity by 39.1 % with respect to 2021.
  • At the end of 2022, renewable energies in Catalonia accounted for 30.9 % of the installed power capacity in the region, with hydro and wind power accounting for 16.1 % and 11.4 %, respectively.
  • At the end of the year, 80.8 % of the installed power capacity in Extremadura was renewable, compared to 77.7 % in 2021. In total, more than 8,500 MW of green power were generated, representing an increase of 20.9 % compared to the previous year and making it the second fastest-growing region in terms of renewable energies.
    Extremadura has revalidated its national leadership in installed solar photovoltaic power capacity in 2022. Last year, almost 1,500 new MW of this technology were installed, 38.3 % more than the previous year. Thus, the region closed the year with 5,347 MW in service, the largest installed solar photovoltaic power capacity in the country.
  • In Galicia, installed renewable power capacity now totals 7,725 MW and represents 70.6 % of the entire Galician generation fleet.
  • The Balearic Islands have seen the greatest percentage variation in renewable power capacity, with an increase of 37.3 % over the previous year. At the end of the year, it had a total of 225 MW of installed solar photovoltaic power capacity, 47.9 % more than in 2021. Accordingly, renewable power capacity accounted for 12.6 % of the total Balearic Islands power generation capacity in 2022, compared to 9.5 % in 2021.
  • In the Canary Islands, installed power capacity has increased by 6.0 % thanks to the commissioning of 45 new MW of renewable power, 14 MW of wind, and 32 MW of solar photovoltaic. Thus, green energies now account for 25.1 % of the Canary Islands' generation fleet.
