Cádiz province reaches 3,561.8 MW of renewable power, accounting for 18.2% of the total in Andalusia. Photovoltaics is the fastest-growing technology in the province.
Cádiz province added 99.6 megawatts (MW) of renewable electricity generation capacity during the first half of 2026, according to data from the Andalusian Energy Agency, part of the Ministry of University, Industry, Energy and Innovation, as reported by Diario Bahía de Cádiz. This brings the province's total to 3,561.8 MW, which is 18.2% of the installed capacity in Andalusia.
Cádiz is the Andalusian province with the most wind power, with 1,460.8 MW, representing 39% of the 3,744.6 MW of wind power in the region. This figure has slightly decreased compared to 2025 due to the closure of a 2.95 MW park and the revision of another's capacity. The repowering of the Tarifa park, which adds 1.4 MW, partially offsets this decline. As of June 2026, the province has 70 wind farms connected to the grid.
SOLAR ENERGY ADVANCES
The growth in the first half is mainly due to photovoltaics, which has increased from 700 MW in 2022 to the current 1,986.9 MW, accounting for 14.4% of Andalusia's photovoltaic capacity. Of these, 213.6 MW correspond to over 22,800 self-consumption installations, allowing citizens, businesses, and other consumers to generate their own electricity and reduce their dependence on the grid.
The province also has 100 MW of solar thermal power, distributed across two twin plants in San José del Valle with parabolic cylinder technology and seven and a half hours of storage. This represents 10% of Andalusia's solar thermal capacity. There are also three biogas plants, with 4.3 MW, and two hydroelectric plants, with 9.9 MW.
PHOTOVOLTAICS STAND OUT IN ANDALUSIA
At the regional level, solar (photovoltaic and solar thermal) accounts for 14,816.2 MW, with 70.8% of the renewable power in Andalusia coming from photovoltaics and 5.1% from solar thermal. Wind power ranks second, with 3,744.6 MW and 19.2% of the total renewable capacity. Following are hydropower, with 639.5 MW (3.3%), and biomass and biogas, with 313.6 MW.
