Guwahati, July 10: Assam has unveiled its most ambitious power sector roadmap yet, announcing an unprecedented ₹77,353-crore investment plan aimed at transforming the state into a power-surplus state and the green energy hub of the Northeast.

Presenting the Assam Budget 2026-27, Finance Minister Jayanta Mallabaruah said the investment will span pumped storage projects, thermal power, hydropower, solar energy, battery energy storage systems (BESS) and transmission infrastructure, creating a diversified energy portfolio aligned with the state’s long-term industrial and economic ambitions.

The roadmap includes 4,900 MW of pumped storage projects worth ₹27,100 crore, a 3,200 MW ultra-supercritical thermal power plant with an investment of ₹40,000 crore, 137 MW of small hydropower projects, 75 MW of solar power, a 25 MW Battery Energy Storage System (BESS), besides the 120 MW Lower Kopili Hydroelectric Project, which is already in the trial commissioning stage.

The Budget also proposes 11 new small hydropower projects across Karbi Anglong, West Karbi Anglong, Dima Hasao, Udalguri, Biswanath and Sivasagar districts.

New solar projects have been planned for Sonitpur and Namrup, while the battery energy storage system will come up in Kamrup.

Recognising that power generation alone is not enough, the government has earmarked ₹4,600 crore to strengthen the transmission network through new 400 kV corridors and grid substations.

Over the next five years, Assam plans to add 15,000 circuit kilometres of transmission and distribution lines, establish 120 substations, install 20,000 high-voltage distribution systems (HVDS) and reduce transmission and distribution losses from 13.4 per cent to 8 per cent.

The announcement also comes as Assam witnesses major private investments in the energy sector. The Adani Group has already been awarded projects for a 3,200 MW thermal power plant and 2,700 MW of pumped storage capacity, further strengthening the state’s long-term energy security.

With one of the largest power sector investments in its history, Assam is betting on reliable, affordable and cleaner energy to accelerate industrialisation, attract large-scale investments and emerge as the energy gateway to Northeast India.
