El Salvador’s installed electricity generation capacity reached 3,200.61 MW by the end of 2025, according to the dynamic electricity statistics visualization tool of the General Superintendency of Electricity and Telecommunications (Siget). Of this total, 846.62 MW corresponded to photovoltaic plants, making solar the leading technology in the system in terms of installed capacity.
With this figure, photovoltaics accounted for 26.4% of national generation capacity, surpassing both fossil fuel-fired and hydroelectric plants. According to Siget data, solar had already overtaken hydroelectric power in 2024 and, in 2025, also surpassed fossil fuel generation capacity.
Siget reports that renewable technologies totaled 2,072.01 MW, equivalent to 64.7% of total installed capacity, while non-renewable technologies accounted for 1,128.61 MW, or 35.3%.
Of the installed solar capacity, 282.30 MW is represented by large-scale PV facilities operating to the wholesale market, while the remaining 564.32 MW is represented by distributed generation systems in homes, businesses, and industrial facilities.
