El Salvador has experienced a remarkable 160-fold increase in solar energy generation capacity from 2015 to 2023, according to data from the Latin American Energy Organization (Olade). This surge is attributed to the growing number of solar farms across the country, which now contribute significantly to the national energy grid. The nation boasts over 60 solar plants, with 21 of them receiving construction permits during the administration of President Nayib Bukele. These projects represent a $152.6 million investment.
Among the most prominent solar projects are the San Isidro Photovoltaic Solar Park in Cabañas Este, La Independencia 2 in La Libertad Oeste, and La Esperanza Solar Plant in Cuscatlán Norte. The state-run Talnique Solar plant, operated by Inversiones Energéticas (INE), stands out as the first government-owned solar facility, inaugurated in December with a capacity of 17 megawatts peak (MWp).
Currently, El Salvador’s solar plants generate 539.07 gigawatt hours (GWh), accounting for 7.31% of the national energy mix. This marks a significant leap from the 94.8 GWh produced in 2017, according to the General Directorate of Energy, Hydrocarbons, and Mines (DGEHM).
Oscar Funes, Vice President of the Salvadoran Renewable Energy Association (ASER), highlighted that El Salvador is now better positioned in solar energy compared to other countries in the region. He attributed the surge to favorable solar radiation levels and a 33% drop in installation costs over the past five years, as well as streamlined government processes for obtaining permits.
Looking ahead, Funes noted that the development of solar energy projects combined with battery storage is gaining traction, ensuring continuous energy supply day and night. AES El Salvador, a key player in this sector, has built 34 solar plants since opening its first in 2015, further solidifying the country’s position in renewable energy innovation.
