Khandu Explains Siang Project’s Water Storage Capacity
ITANAGAR, September 30: Arunachal Pradesh Chief Minister Pema Khandu has sought to explain the difference between hydropower capacity and water-storage capacity in the context of China’s proposed Medog project and India’s proposed Siang Upper Multipurpose Project (SUMP). Khandu said the central issue is storage, not merely installed power capacity. He stated that the Medog project is reported to have around 5.5 billion cubic metres (BCM) of estimated storage, while SUMP is proposed with about 9.2 BCM of live storage. The comparison addresses a question that has emerged repeatedly in discussions around the Siang project: how a proposed 11,000 MW project could have a greater storage figure than a project upstream reportedly capable of generating around 60,000 MW. Khandu pointed out that megawatts and water storage measure different things. Hydropower generation depends partly on the height through which water falls, meaning a project can generate substantially mor...
