El Salvador sourced 65.01% of its electricity demand from renewable energy in June, according to the latest market report from the Unidad de Transacciones (UT). The country consumed a total of 588.65 gigawatt hours (GWh) during the month, with the remainder—34.9%—covered by power plants fueled by bunker and liquefied natural gas (LNG).
Hydropower led renewable generation with 205.27 GWh, or 33.78% of the total demand. This marks a significant increase compared to previous months, where hydro’s share remained below 20%. “Higher rainfall improved reservoir levels and made hydropower the most cost-effective source,” the UT explained.
LNG, supplied mainly by the Energía del Pacífico (EDP) plant in Acajutla, accounted for 30.48% of the demand with 185.18 GWh. Although not a renewable source, natural gas is considered transitional due to its lower environmental impact compared to petroleum-based fuels. Bunker-based plants contributed just 4.42%, or 26.83 GWh.
The rest of the demand was met through geothermal (121.33 GWh, 19.97%), solar (45.04 GWh, 7.41%), wind (5.11 GWh, 0.84%), and regional imports (18.05 GWh, 2.97%). Biomass was absent from the mix due to the end of the 2024-2025 sugarcane harvest, which typically fuels production from November to April.
June’s peak energy demand occurred on the 3rd at 7:30 p.m., reaching an injection of 1,134 megawatts (MW). The average price per MW dropped to $98.12, the lowest since February and a 21.8% decrease compared to May.
Total electricity consumption in June fell by 56.63 GWh, an 8.7% decline from the 645.28 GWh recorded in May.
