en.Wedoany.com Reported - AES El Salvador and ECORAY have commissioned the Santa Ana IV solar power plant in Santa Ana, western El Salvador, with a rated capacity of 55 MW and a peak capacity of 73 MWp. The project, with an investment of over $60 million, is the largest solar power plant operated by AES in El Salvador.

The plant is equipped with 124,432 bifacial solar panels of 585 W each, along with a tracking system. The electricity generated by Santa Ana IV will be fed into the national transmission grid to meet the power demand in the western region of the country.

With the commissioning of Santa Ana IV, AES El Salvador's total number of solar power plants in the country has increased to 18, with a total installed capacity (rated power) of 186 MW. The company stated that this portfolio accounts for approximately 25% of the country's solar power generation.

AES El Salvador currently operates multiple solar projects, including the 100 MW Bósforo complex in partnership with CMI, the 5.2 MWp Opico Power, the 4.10 MW Ilopango Solar, and the 1.3 MWp AES Meanguera del Golfo project with 4 MWh of energy storage.

AES began renewable energy development in El Salvador in 2011, with its first project being a biogas plant in Nejapa.

According to the latest data from the Unidad de Transacciones (Transaction Unit), as of November 2025, El Salvador's photovoltaic installed capacity had reached 734.23 MW, accounting for 23.6% of the total system capacity. Including Santa Ana IV (rated capacity 55 MW, peak capacity 73 MWp), the country's solar installed capacity will approach 790 MW (rated power), with final figures pending official statistical updates.
