The commissioning process of a run-of-the-river hydroelectric project coming up on Subansiri, a tributary of Brahmaputra has started, with four units of 250 MW each set to begin operations between mid-November and December-end. Construction on the project began in 2005, but like several other infrastructure projects, it got mired in delays—both man-made and natural. Massive protests by locals against the project had held up work for eight years. Work resumed in 2019 only to be hit again by landslides. Today, 96 percent of the project is complete. Once fully operational in 2026, it will not only create an energy surplus in the Northeast, but will go a long way in mitigating the impact of floods in the Brahmaputra.
