The electrical system in El Salvador is characterized by the participation of seasoned operators with extensive experience in the electrical industry and a regulatory framework that promotes the efficient operation of the electricity system.
The Salvadoran electricity market is the most open in the region. Such opening was promoted in 1996 with the approval of the General Electricity Law and its regulations, which fostered a competitive market and private participation in the generation, distribution and commercialization of electricity.
El Salvador has an institutional structure adequate for the development, regulation and operation of the electricity market:

SIGET (The Superintendence for Electricity and Telecommunications) established quality standards for the continuity, voltage levels and disruption in the power supply, thus insuring the quality of service provided to end users by distributors.

El Salvador is a leader in the geothermal energy use (25% of its generation), and ranks among the ten most productive locations in geothermal energy in the world. The existence of substantial geothermal resources, added to the extensive professional experience in the development of this type of generation and the appropriate expansion policies, will allow furthering the country´s potential in this energy source.
Salvadoran regulation allows companies to generate their own energy and sell their surplus.
