Tata Power And DGPC Take Hydropower Partnership Past 5,033 MW

The expanded portfolio comprises Khorlochhu (600 MW), Dorjilung (1,125 MW), Gongri Reservoir with Jeri pumped storage (2,540 MW combined), Chamkharchhu IV (364 MW) and the newly included Nyera Amari projects (404 MW), and the partners are also pursuing 500 MW of solar photovoltaic capacity. The document notes that the two parties have collaborated for more than 15 years, beginning with the 126 MW Dagachhu project commissioned in 2008 as Bhutan’s first public-private hydropower venture. This sequence of projects reflects a deliberate push to scale generation and storage capability across river basins and reservoir models.

Work is already underway on Khorlochhu and Dorjilung, which together account for roughly 35 per cent of the committed five gigawatt (GW) portfolio. The mix of reservoir, run of river and pumped storage is intended to support seasonal balancing and improve regional supply adequacy during peak demand.

The amendment was signed in the presence of Bhutan’s Prime Minister Lyonchhen Tshering Tobgay, with Tata Power’s chief executive and DGPC’s managing director formally executing the agreement and senior officials in attendance. Company leadership described the expansion as a milestone for Bhutan’s clean energy trajectory and said it would bolster economic growth while strengthening regional energy security. The partners indicated that the enhanced portfolio should improve access to reliable, low carbon power for India and Bhutan alike.
