Chapar Project Gets Foundation Stone for 3,200 MW Assam Plant
Adani Power Begins Work on ₹48,000 Crore, 3,200 MW Assam Power Plant
Assam Chief Minister Himanta Biswa Sarma on Sunday laid the foundation stone for Adani Power Limited’s 3,200 MW ultra-supercritical thermal power plant at Chapar in Dhubri district, setting in motion one of the largest private power projects announced for the state.
The project involves an investment of about ₹48,000 crore. Adani Power expects it to provide work for up to 20,000 people during construction and about 5,000 people after the plant starts operating. The first units are scheduled to be commissioned from December 2030, with the full project planned in phases.
The plant will have four units of 800 MW each. It will use ultra-supercritical technology, which operates at higher temperatures and pressures than older coal-fired plants. Higher operating efficiency can reduce the amount of coal needed for each unit of electricity produced.
For Assam, the project comes as electricity demand has risen with urban growth, industry and wider access to power. The state government’s electricity department has previously reported that Assam’s average peak demand had reached about 1,400 MW, roughly twice the level recorded five years earlier. Assam has also depended heavily on hydroelectric generation, much of it linked to rainfall.
The size of the new plant is therefore considerable when compared with the state’s recent demand figures. Once all four units are operating, the project will have a capacity of 3,200 MW.
Sarma said the project was linked to the investment push created by Advantage Assam 2.0, the state government’s Investment and Infrastructure Summit held in Guwahati in February 2025.
“Assam is fast emerging as the region’s energy hub, with several mega energy projects in the pipeline. The 3200 MW Chapar project is a proud outcome of the confidence generated by the Advantage Assam Investor Summit 2.0. With an investment of nearly ₹48,000 crore, this project will constitute one of the largest single investments ever made in Assam. Besides providing massive employment opportunities, the State will also benefit through increased economic activity and SGST revenues, while local industries and enterprises will have opportunities to participate in the emerging ecosystem.”
The state government held Advantage Assam 2.0 on February 25 and 26, 2025, with energy, infrastructure, manufacturing, logistics and other sectors among its focus areas. The summit was inaugurated by Prime Minister Narendra Modi.
For Adani Power, the Chapar project follows the award of a long-term power supply contract from Assam Power Distribution Company Limited. The company emerged as the successful bidder in October 2025 and received the Letter of Award in November that year.
Adani Power’s regulatory filing said the project is being developed on a Design, Build, Finance, Own and Operate model. Power from the entire 3,200 MW capacity is covered by the long-term arrangement with APDCL. The company has said commissioning will begin in December 2030 and be completed by December 2032.
Jeet Adani, Director, Adani Group, said the company would invest ₹48,000 crore in the plant.
“Today marks the beginning of an important new chapter for Assam. Adani Power will invest ₹48,000 crore in this 3,200 MW thermal power project, bringing reliable and affordable electricity to support homes, businesses and industries. The project will also create jobs and open up opportunities for local contractors, suppliers and businesses. We are proud to invest in Assam and be part of the state’s economic growth.”
He also referred to Assam’s geography and described the state as a potential “battery” for India.
The Chapar plant is part of a wider ₹63,000 crore power investment announced by Adani Group companies in Assam. Adani Green Energy Limited has plans for two pumped storage projects with a combined capacity of 2,700 MW, involving about ₹15,000 crore. Adani Energy Solutions Limited is also carrying out smart metering work in the state.
The pumped storage projects are designed to support electricity storage by moving water between reservoirs at different levels. Such facilities can help balance electricity supply when demand changes and can work alongside renewable power sources.
The group’s activity in Assam also extends beyond electricity. Its airport business operates Lokapriya Gopinath Bordoloi International Airport in Guwahati. The airport’s new terminal began commercial operations on February 22, 2026, increasing the airport’s annual passenger capacity to 13.1 million.
The Adani Foundation has also reported relief work for more than 8,000 flood-affected families in Sivasagar and Dhemaji districts. Its programmes in 19 villages in Kamrup Rural include education, healthcare, livelihoods, community infrastructure and climate-related work.
Across its businesses, the group has said its planned and ongoing investments in Assam will exceed ₹80,000 crore. These include power, renewable energy, aviation, cement and electricity distribution.
The economic effect of the Chapar project will extend beyond the plant site if the expected construction activity develops as planned. Large power projects require a wide range of services, including transport, civil works, equipment supply, maintenance and other local contracting work. The scale of the investment could therefore bring business opportunities for companies operating around Dhubri and other parts of Assam.
The project also places a long construction period ahead. With the first commissioning target set for December 2030 and completion scheduled by December 2032, the benefits linked to full power generation will take several years to appear.
For Assam, the immediate development is the start of construction. The longer-term test will be whether the project is completed on schedule and whether the additional electricity capacity supports the state’s growing household, commercial and industrial demand.
