Bharat Heavy Electricals (BHEL) has commissioned two units of the 6x170 mw Punatsangchhu-II Hydroelectric Project (PHEP-II) in Bhutan.
The project is executed under a bilateral agreement between the Government of India and the Royal Government of Bhutan. PHEP-II is a greenfield hydroelectric project located in the Wangdue district of Western Bhutan.
The Francis Turbine installed at the site is designed to operate at a rated head of 241 metres, which is the highest for any Francis-type hydro turbine in Bhutan. Upon full commissioning of all the six units, the expected annual power generation will be 4,357 gw hours.
Unit 1 and 2 of the 670-mw PHEP-II were synchronised on December 16 and 17, 2024, respectively. BHEL’s scope in PHEP-II comprises design, manufacture, supply, installation and commissioning of electromechanical works for 6x170 mw vertical Francis turbines and matching synchronous generators, a control and monitoring system, generator transformers, shunt reactors, bus ducts, pothead yards and associated auxiliaries.
The equipment for the project has been supplied by BHEL’s units in Bhopal, Jhansi, Rudrapur, Bengaluru and its transmission business group. Erection and commissioning on site have been carried out by the company’s power sector (eastern region) division based in Kolkata.
BHEL has executed major projects like 4x84-mw Chukha, 4x15-mw Kurichhu, 6x170-mw Tala and 4x180-mw Mangdechhu in Bhutan till date. With the commissioning of these two units at PHEP-II, BHEL’s contribution to the total installed capacity in Bhutan now stands at nearly 89 per cent.
