Agency: According to the Minister of Energy and Natural Resources Lyonpo Gem Tshering, the Adani Group has indicated a preference for a run-of-the-river (RoR) model over a reservoir-type scheme for the development of the Wangchhu Hydropower Project.
The RoR scheme option at 570 MW is designed to include peaking capabilities during the lean season, allowing for a minimum four-hour power generation window in a 90% dependable year. It is projected to deliver 1,968.55 GWh of energy annually, with a firm power capacity (winter generation) of 94.96 MW.
In contrast, the alternative 900 MW reservoir-based scheme, though capable of producing 1,919 GWh annually and offering a higher firm power capacity of 126 MW, appears to be less favored by Adani following preliminary assessments.
