Nangalbibra-Bongaigaon Transmission Line (NBTL) is enhancing power infrastructure in Northeast India, enabling 1000MW electricity transfer to Meghalaya and Assam. This infrastructure project ensures reliable power transmission from Assam to Meghalaya. In addition to providing an additional 1000MW of power supply, the project also decongests the downstream networks in the region, thereby improving the quality and reliability of power supply in Northeast India.

The project involved laying around 300 km of transmission lines across the challenging Northeastern terrain of Assam and Meghalaya and constructing a greenfield substation with a 300 MW transformation capacity at Nangalbibra in Meghalaya.
