In its initial two and a half decades, the expansion of ENEE was boosted by the technical and financial support of international financial organizations. Hydroelectric projects abounded and the transmission network expanded to incorporate all economically active areas of the country into the national grid, which was interconnected with Nicaragua (1976), Costa Rica (1982) and Panama (1986). The largest project, the hydroelectric plant of El Cajón (300 MW) on the Rio Comayagua in Central Honduras was commissioned in 1985. At that time Honduras had an installed capacity of 560 MW and a peak demand of only 220 MW.
