India Unveils Rs 6.4 Trillion Transmission Blueprint to Evacuate Brahmaputra Hydropower by 2047

The blueprint signals a push to shift northeastern hydropower into the national grid to bolster energy security.

Overview

  • The Central Electricity Authority published a two-phase plan costed at Rs 1.91 trillion to 2035 and Rs 4.52 trillion beyond 2035, totaling about Rs 6.4 trillion.
  • The plan targets evacuation of roughly 65–76 GW from 12 sub-basins, including 64.9 GW of large hydro and 11.1 GW of pumped storage, with 4,807 MW already installed and about 2,000 MW under construction.
  • Network buildout calls for about 31,000 circuit-kilometres of lines, 68 GVA of transformation capacity and 42 GW of HVDC corridors, with detailed phase-wise additions.
  • Projects are mapped to central PSUs such as NHPC, NEEPCO and SJVN, giving developers clarity on future evacuation capacity as schemes move through approvals and construction.
  • Officials frame the effort as supporting clean-energy targets and addressing risks from China’s upstream dam on the Yarlung Zangbo, with India’s peak demand projected to keep rising through 2047.
