A mega interstate transmission project powers Northeast India
India strengthens its grid by adding more than 3000 MW of power to the Northeastern region of the country, supplying 53 million people.
India strengthens its grid by adding more than 3000 MW of power to the Northeastern region of the country, supplying 53 million people.
With growing demand, stronger interconnections were needed in the Northeastern region of India to the national power grid. The Ministry of Power’s answer to this need was interstate transmission project NER-II.
The NER-II project was designed to transmit more than 3000 MW to the Northeastern region of India. In addition to strengthening the grid, this project was designed to play a vital role in enabling access to a reliable source of power for the region. This interstate transmission system includes 11 elements, including two substations with a combined transformer capacity of 1250 MVA and four transmission lines supported by 1008 towers over a distance of approximately 830 km.
The project kicked off in March 2017 and estimated completion dates for the different system elements ranged from 36 to 44 months. Despite all the challenges during the three-year project period, all elements were commissioned from February 2021 to April 2021.
In addition to providing reliable supply of power to the region, this project was a true harbinger of sustainable development. Apart from enhancing the reliability and availability of the power supply, the project has the potential to boost the annual per-capita electricity consumption in the Northeastern region from 402 kWh today to the national average of 1208 Wh.
With the successful commissioning and completion of the mega NER-II project, more than 3000 MW of power is now delivered to the people in Northeastern India. The most difficult and treacherous terrain had to be overcome to build this crucial power corridor with the help of innovative technologies.
