According to IFC, the project will support BDSN’s operational 180 MW Asahan-1 hydropower plant (HPP) in North Sumatra, Indonesia. The plant has been fully operational since January 2011 and sells electricity to PLN pursuant to a long-term PPA expiring on Dec 31, 2040 on a take-or-pay basis of 1,175 GWh of electricity per year. Asahan-1 is developed by the Independent Power Producer (IPP) BDSN.
The HPP located 25 km downstream of Lake Toba on the Asahan River in North Sumatra, Indonesia, is approximately 130 km southeast of the city of Medan. Construction restarted in 2006/7 and the HPP was finally commissioned in 2010. The operation and maintenance (O&M) since January 2014 has been contracted to PJB Services (PJBS), a subsidiary of PJB Asahan-1 is a run-of-river scheme developed to utilize the hydraulic head between the Regulating Dam and Siguragura Dam of the pre-existing Asahan-2 project, a three dam cascade developed between 1975-1982 to support the PT Inalum smelter, located on the North Sumatra coastline near Medan. The Asahan-2 scheme, which is not part of this project, comprises a 39 m Regulating Dam, a 47 m, 286 MW Siguragura Dam and HPP, and a 73 m, 317 MW Tangga Dam and HPP.

The Asahan-1 HPP comprises of a 6.5 km tunnel, 70 m surge shaft, 275 m penstock, powerhouse with two 90 MW Francis turbines, accommodation camp and switchyard (the latter handed over to PLN).
