 Two streams, Builai and Wainalale were selected to provide water to the power station.
 Construction began in 2006.
 A 2 m tall embankment dam was constructed on Builai stream and a second 1 m high dam was built on Wainalale stream.
 Connecting the dams to the power station is 2200 m of penstock.
 A single 326 kW Pelton turbine-generator is located in the power station which was commissioned in November 2008.
