Erathna Mini Hydro Power Project

The Erathna Mini Hydro Power Project is a hydroelectric facility in Ratnapura District that converts flowing water from the Kuru Ganga river into electricity. The site combines weirs, channels, and turbines to harness the river's natural energy and feed power into the national electrical system.

Construction of this facility began in 2001 and was completed in 2004, marking an important milestone in Sri Lanka's renewable energy efforts. Its completion provided the region with a dependable local source of electricity for long-term development.

The power station operates near Adam's Peak, integrating industrial development with respect for local geographic and environmental conditions of the Ratnapura region.

The facility sits in a mountainous area with steep gradients that support electricity production. Visitors should wear sturdy footwear and bring appropriate clothing, as the paths to and around the plant are uneven and hilly.

The plant operates with a vertical drop of over 460 meters between its water intake and powerhouse. This significant elevation difference allows the facility to generate electricity efficiently despite the remote mountain location.
