Project Details


Central America's Siepac grid project aims at creating an integrated power market across the region. It is expected to alleviate periodic power shortages in the region, reduce operating costs, and optimize shared use of hydroelectric power. EPR, a consortium of private and public companies from Central America, Mexico, Colombia and Spain, is tasked with owning, constructing and operating the project. The 1,790km grid will connect Costa Rica (493km), El Salvador (286km), Guatemala (281km), Honduras (270km), Nicaragua (310km) and Panama (150km), initially allowing 300MW of transactions. The project includes 15 substations and 4,622 towers. After the line is built, a connection could be made with Mexico and Colombia, integrating the Siepac network into the enormous North and South American power markets.
