PV self-consumption in Spain has proven itself as a structural driver of the energy transition, even though the sector has experienced three consecutive years of contraction and is currently lagging behind the pace needed to achieve the objectives of the National Integrated Energy and Climate Plan (PNIEC). This is evident from the fourth edition of the Annual Report on Self-Consumption of Photovoltaics and Storage 2025, prepared by APPA Renovables.
In 2025, 1,214 MW of new capacity for self-consumption was installed, of which 846 MW in the industrial and commercial segment and 368 MW in the residential segment. In concrete terms, there were 66,909 residential installations and 4,700 industrial installations, with an average power of 5.5 kW and 180 kW respectively.
This brings the total installed self-consumption capacity to 9,590 MW, corresponding to approximately 24% of Spain’s annual peak electricity demand (approximately 40 GW).
