The Jorethang Loop Hydroelectric project (JLHEP) is developed by DANS Energy Private Ltd (DANS Energy) on the Rangit River in the state of Sikkim, India. The Rangit River is a tributary of the Teesta River, which is the main river traversing the state of Sikkim. The project has Generator installed capacity of 96 MW and generates approximately 444.03 GWh (gross) per annum.
The project activity is a hydroelectric project which utilizes the potential energy from a natural height drop of approximately 84m over a 12.8km stretch of the Rangit River. A diversion barrage, 108 m in length and 17m in height has been constructed which created a reservoir of approximately 14.489 ha. The flow is directed from the reservoir, through an intake tunnel on the east bank of the river, into head race tunnel, through a surge shaft and pressure shaft to the powerhouse. The powerhouse is house 2 x 48.75 MW vertical shaft type Francis turbines, that is coupled with synchronous generators of capacity 2 x 48 MW. The flow is discharged via a 40m tail race channel back into the Rangit River. The project components from the head race tunnel to the flow discharge is located underground.
The unit I of 48 MW was commissioned on 26/09/2015 and unit II of 48 MW was commissioned on 01/10/2015.
