Power generation potential of Seethawaka Ganga was originally studied by the Department of Irrigation in the year 1961 with the assistance of “Technopromexport Moscow”. Thereafter, during 1988 power generation potential of the Seethawaka Ganga has been confirmed in the report called SITA-14 prepared under “Master Plan for the Electricity Supply of Sri Lanka”.
Since then no action being taken to develop the project and in the year 2009, Pre-Feasibility studies of the project has been carried out by Sri Lanka Energies (Pvt.) Limited. (SLE), a subsidiary of CEB. In the Year 2013, CEB took over the project development to harness the optimum hydro potential available within the area. This was added to the Long Term Generation Expansion Plan 2015-2034 targeting to commission the plant in the Year 2022.
The Project Management Unit for Seethawaka Ganga Project was established in September, 2016. The detailed feasibility has been completed in December 2018 which was jointly carried out by Central Engineering Consultancy Bureau (CECB) and Engineering Advisory Branch of CEB. The environmental impact assessment studies are in progress and scheduled to be completed by end of April 2020. According to the studies, the project will implement as 24MW plant and estimated annual energy generation is 54 GWh. Estimated Total cost of the Project is USD 79 million and scheduled duration of the construction period of the project is three (03) Years. According to the present progress, commissioning of the plant is planned in the year 2024.
The project area will be within the premises of Maldeniya, Dangampala, Reucastle, Higuralakanda, Dankombuwa, Digala & Yogama villages that situated along the Seethawaka Ganga in Batangala, Algoda, Hinguralakanda East and Dikella Grama Niladhari Divisions of Dehiowita Divisional Secretary Division in Kegalle District of Sabaragamuwa Province.
