This run-of-river mini hydro power project having the install capacity of 7.2 MW. Through the operation, the plant is expected to generate emission free electricity of around 25 GWh annually and will be exported to the grid.

The project company is Country Energy (Pvt) Ltd which is a subsidiary of Vallibel Power Erathna PLC. The project is located near Durekkanda, in the Ratnapura Divisional secretariat of the Ratnapura District. The plant uses the water flow of the Denawaka Ganga, which is a main tributary of the Kalu Ganga. The project comprises of diversion weir, headrace channel, forebay tank, penstocks, powerhouse, tailrace and switchyard.

This is an environmental friendly renewable energy project which replaces electricity generated by fossil fuel based power plants and by implementing this project, approximately 13,500 tonnes of CO2 will be reduced annually. In addition to the reduction of green house gas emission from existing thermal plants, this project will create many social and environmental benefits, including employment opportunities, construction of infrastructure and preserving valuable fossil fuel.
