'''Jorethang Loop Hydroelectric project''' is a {{convert|96|MW}}, [[run-of-the-river]] [[hydroelectric]] [[power station]] on the [[Rangeet River|Rangit river]] in [[South Sikkim district]] of [[Sikkim]] state in [[India]].<ref name=":0">{{Cite web|url=https://cdm.unfccc.int/filestorage/F/2/K/F2K3QEYXB5P8C7HRJTZMG40W1OAINV/UN1326_MR_DANS%20Energy%20Pvt.%20Ltd_%20V03_13022017?t=TDd8cGxjeXdvfDB-8_apsMbaFQRyOxc8TEiD|title=Monitoring report - Jorethang Loop Hydroelectric Project, India|website=[[Clean Development Mechanism]]|access-date=15 January 2019}}</ref> The dam is located near village Piple and power station is located about 13&nbsp;km downstream near village Majhitar. Dans Energy Private Limited was awarded contract for construction of the project. The project was officially inaugurated on 29 October 2015.

<br />
== Powerhouse ==<br />
The dam is located about 5&nbsp;km upstream from [[Jorethang]] and powerhouse is located about 13&nbsp;km downstream from dam site at {{Coord|27|06|29|N|88|19|27|E|name=Jorethang Loop HEP}}. Water is diverted from barrage through 6.8&nbsp;km long head race tunnel, through a surge shaft of 25 m dia. and pressure shaft to power house near village Majitar. The powerhouse has 2 x 48.75 MW vertical shaft type [[Francis turbine]]s that generate 2x48 MW power. The water flow is discharged back into Rangit river through a 40m tall race channel. With installed capacity is of 96 MW project is expected to generate approximately 444.03 GWh per annum.<ref name=":0" /><ref>{{Cite web|url=https://offset.climateneutralnow.org/jorethang-loop-hydroelectric-project-india-1326-|title=Jorethang Loop Hydroelectric Project, India|website=United Nations [[Carbon offset]] platform|access-date=15 January 2019}}</ref><br />
<br />
==Power transmission==<br />
The electricity generated is connected to switchyard near powerhouse and evacuated through double circuit 220 kV transmission line to the New Melli 220KV switching substation. New Melli sub station is located about 10&nbsp;km away from powerhouse and connected to Eastern Regional Grid.<ref name=":0" /><ref>{{Cite web|url=http://forestsclearance.nic.in/writereaddata/Addinfo/0_0_51127122712121Briefnarrativeofthescheme.pdf|title=Power Transmission system from Sikkim|website=[[Ministry of Environment, Forest and Climate Change]] - [[Government of India]]|access-date=15 January 2019}}</ref><br />
