The project activity is a run-of river type hydro power plant in North Sumatra province in Indonesia. The total actual installed capacity of the project is 50 MW, comprised of a 33 MW and a 17 MW turbine, with a predicted electricity supply to the grid of 214,800 MWh per annum1. The project is owned and developed by PT. PLN (Persero), a state-owned electricity company in Indonesia. The project generates and supplies the electricity to the connected Sumatra grid. The electricity currently generated by the grid is relatively carbon intensive. The proposed project will increase the utilization of renewable energy sources, in this case hydro energy, by operating new hydropower plant.
