Guwahati: Assam has taken a major step towards expanding its power generation capacity with the launch of a 3,200 MW ultra-supercritical thermal power project at Chapar in Dhubri district, an investment that the state government has described as one of the largest single investments in Assam.
Chief Minister Himanta Biswa Sarma announced the development in a social media post, saying the 3,200 MW project in western Assam is expected to generate enough electricity to meet the state’s power requirements. He said the ₹48,000-crore project is a direct outcome of the investment momentum generated by the Advantage Assam 2.0 summit held 18 months ago.
The foundation stone for the project was laid by Chief Minister Sarma on September 20 at Chapar. The project is being developed by Adani Power Limited and will comprise four units of 800 MW each, using ultra-supercritical technology. According to the company’s official announcement, the plant is scheduled to be commissioned in phases beginning in December 2030.
The project is expected to significantly increase Assam’s power-generation capacity and support the state’s growing household, commercial and industrial electricity requirements. Adani Power has said the plant could create up to 20,000 employment opportunities during the construction phase and around 5,000 jobs once it becomes operational.
The Chapar project is part of a larger ₹63,000-crore power investment planned by the Adani Group in Assam. Of this amount, around ₹48,000 crore is earmarked for the thermal power plant, while approximately ₹15,000 crore is planned through Adani Green Energy for two pumped storage projects with a combined capacity of 2,700 MW.
The project also has a long-term power supply arrangement with the Assam Power Distribution Company Limited (APDCL). Adani Power’s investor disclosures state that the company received a 25-year Power Purchase Agreement for 3,200 MW from APDCL, with electricity to be supplied from the new four-unit ultra-supercritical project at Chapar.
The Assam government’s power requirements are expected to grow as industrial activity, electrification and economic activity expand. A 2025 response by the Union Ministry of Power, citing the Central Electricity Authority’s 20th Electric Power Survey, projected Assam’s peak power demand at about 7,006 MW by 2041-42. The same response said Assam’s contracted capacity requirements would also increase considerably in the coming years.
The state already relies on a combination of its own generation capacity and power purchased through agreements with central generating companies. APDCL, which is responsible for electricity distribution in Assam, has also been expanding and modernising the state’s distribution network.
Speaking at the foundation ceremony, Adani Group Director Jeet Adani said the company would invest ₹48,000 crore in the Chapar project and that the development would create opportunities for local contractors, suppliers and businesses. He also highlighted Assam’s potential to play a larger role in India’s energy sector.
The project is being positioned as a major addition to Assam’s energy infrastructure, with its phased commissioning expected to begin from December 2030. Once all four units are operational, the Chapar plant will have a total generation capacity of 3,200 MW.
