[1][2] With an estimated annual generation capacity of 126 GWh, the facility will be the country's last major hydroelectric project, due to the exhaustion of island-wide hydropower potential.

Construction of the project was ceremonially inaugurated by the Minister of Power and Energy Mrs. Pavithra Wanniarachchi at the auspicious time of 11:01 on 17 July 2013.
