Projects under implementation through JV model:

4. Kholonghchu HEP is 600 MW run-of-the-river in the lower course of Kholongchhu river in Trashiyangtse district of Bhutan. It is the first HEP in Bhutan to be implemented under the Joint Venture model, by a JV-company between Druk Green Power Corporation(DGPC) of Bhutan and SJVN Ltd. of India. The foundation stone for the first HEP 600 MW Kholongchhu was laid by Prime Minister Shri.
