Wind Turbines Above the Tempisque Valley, Guanacaste

Guanacaste's wind farms sit along the mountain corridors near the Tempisque River basin, where steady northeast trade winds funnel through gaps in the Cordillera de Guanacaste. The region's wind-power development began in the early 1990s near Tilarán, among the first utility-scale wind installations in Latin America. Costa Rica's state utility, ICE, along with private operators, has since expanded turbine arrays across these hills to feed the national grid, which runs on renewable sources for most of the year. The consistent wind pattern that draws turbines to this landscape is the same seasonal airflow that makes nearby Lake Arenal a destination for windsurfing.
