A consortium of Bhutanese construction firm Rigsar and India’s HILD Energy Ltd. has secured a contract for the Design, Supply, Installation, Testing and Commissioning of a 120 MW solar project in Bhutan.
It will be built on approximately 385 acres (156 hectares) of state-reserved forest land, around 25 km away from Bhutan’s capital, Thimphu. Once operational, the installation will be Bhutan’s largest solar project to date. The country's first utility-scale solar plant, a 17.38 MW array, was inaugurated in July 2025.
The total project value is estimated at USD 50 million. Its initial feasibility study was carried out by Druk Holding and Investments (DHI) before responsibility for further studies and implementation was transferred to Druk Green Power Corporation Limited (DGPC). Electricity generated from the solar arrays at each of the three sites will be transmitted via 33 kV double-pole structures to Bhutan Power Corporation’s 220/66/33 kV substation, where it will be integrated into the national transmission and distribution grid.
