The Project is a run of-river hydroelectric power project in North Sumatera Province in Indonesia. The Project uses the existing flow of Asahan River to produce electricity and it has no large scale dam or reservoir build for the project, as it is a run-of-river hydroelectric power plant. The Project is taking advantage of Asahan River flow that receives water from its natural source, Lake Toba. Geographically, the Project is located downstream of Lake Toba and upstream of the existing Asahan 2 (Siguragura) hydroelectric power plant, a large dam power plant built in 19811. The objective of this Project is to supply zero emission energy to Sumatera Grid, a grid with relatively carbon-intensive electricity supply that is located in Sumatera Island and currently has no interconnection with the grid in other islands.
