Adani Power has begun construction of a 3,200 MW ultra-supercritical thermal power plant at Chapar in Assam’s Dhubri district. The ₹48,000 crore project is expected to become one of the Northeast’s largest power generation assets, with commissioning planned in phases from December 2030.
Adani Power Assam Project Gets Foundation Stone
The Adani Power Assam project moved into the execution phase after Assam Chief Minister Himanta Biswa Sarma laid the foundation stone for the 3,200 MW thermal power plant at Chapar in Dhubri district on September 20, 2026.
The project involves an investment of around ₹48,000 crore and will consist of four units of 800 MW each. It will use ultra-supercritical technology, which is designed to operate at higher temperatures and pressures than conventional coal-fired generation systems.
The project is significant for Assam because it adds a large new generation facility to the state’s electricity infrastructure. According to the company, commissioning is scheduled in phases beginning December 2030.
The development also marks the conversion of an investment commitment announced earlier into an on-ground infrastructure project.
₹48,000 Crore Plant Will Have 3,200 MW Capacity
The Chapar project will have a total installed capacity of 3,200 MW, divided across four 800 MW generating units.
Adani Power received a Letter of Award from Assam Power Distribution Company Limited for the long-term supply of the project’s entire capacity. The plant is being developed under a Design, Build, Finance, Own and Operate model, with fuel linked to coal allocated under the SHAKTI policy framework.
The project is expected to become the largest power generation asset in Northeast India once fully commissioned, according to Adani Power and company officials.
The first generation capacity is expected to come online from December 2030, with the remaining units scheduled to be commissioned in phases. A Times of India report said full capacity is scheduled by 2032.
Assam Power Investment Forms Part of ₹63,000 Crore Plan
The ₹48,000 crore thermal power project is only one part of a larger energy investment programme announced by the Adani Group in Assam.
Adani Power plans to invest approximately ₹48,000 crore in the Chapar plant, while Adani Green Energy has proposed an additional ₹15,000 crore for two pumped storage projects with a combined capacity of 2,700 MW.
Together, these projects represent around ₹63,000 crore of planned power-sector investment in Assam.
The pumped storage projects are separate from the thermal power plant and are intended to add energy storage capacity. Adani Energy Solutions is also implementing smart metering projects in Assam as part of the group’s wider presence in the state’s power infrastructure.
This makes the Chapar project part of a broader expansion across generation, storage and distribution rather than an isolated investment.
Project Expected to Create Thousands of Jobs
The Adani Power Assam project is expected to generate substantial employment during construction.
According to Adani Power, the project could create up to 20,000 jobs during the construction phase and around 5,000 jobs once the plant becomes operational. The project is also expected to create opportunities for local contractors, suppliers, transport operators and service providers.
The economic impact could therefore extend beyond direct employment at the power plant.
Large infrastructure projects typically require construction materials, transportation, engineering services, maintenance, logistics and other support services. For Assam, the development could increase commercial activity around the project location as construction progresses.
The state government has also highlighted the potential for additional economic activity and tax revenues associated with the investment.
Ultra-Supercritical Technology Planned at Chapar
The Chapar power plant will use ultra-supercritical technology, a higher-efficiency form of coal-based thermal generation.
The technology operates at higher steam temperatures and pressures than conventional subcritical plants. This allows more electricity to be generated from a given quantity of fuel and can improve thermal efficiency.
The project is being positioned by Adani Power as a modern thermal generation facility with high-efficiency systems and environmental safeguards.
However, the plant will remain a coal-based thermal power project. Its development therefore sits alongside Assam’s planned investments in pumped storage and other energy infrastructure.
The combination reflects the state’s broader effort to expand electricity generation while also developing storage capacity for its future energy requirements.
Power Supply to Support Assam’s Industrial Growth
Adani Group Director Jeet Adani said the project is intended to support homes, businesses and industries by adding reliable electricity generation capacity.
The company has described the plant as an important addition to Assam’s power base and said it will support industrial and commercial activity in the region.
For businesses, reliable electricity supply is an important part of operating infrastructure. Manufacturing facilities, commercial establishments and other energy-intensive industries require consistent power availability to maintain production and services.
The impact of the Chapar project, however, will depend on the plant’s eventual commissioning schedule, operating performance and the broader development of Assam’s electricity transmission and distribution network.
The project’s entire 3,200 MW capacity is linked to a long-term power supply arrangement with Assam’s distribution utility, according to Adani Power.
Adani’s Assam Investment Extends Beyond Power
The ₹48,000 crore Chapar project is part of a wider Adani Group investment footprint in Assam.
The group has investments and announced projects across sectors including power, renewable energy, aviation and cement. Its energy plans alone include the Chapar thermal plant and two pumped storage projects worth a combined ₹63,000 crore.
The group has also highlighted its investment in Terminal 2 at Lokpriya Gopinath Bordoloi International Airport in Guwahati, which became operational in February 2026.
The Assam government has linked the latest investments to the state’s Advantage Assam Investor Summit 2.0 and its efforts to attract large private-sector projects.
For the Adani Group, the Chapar plant represents a major expansion of its power generation capacity in India’s Northeast.
What Comes Next for the Chapar Project
The immediate focus will be construction of the four generating units and associated infrastructure at Chapar.
The project is scheduled to begin commissioning in phases from December 2030. Once operational, the full 3,200 MW facility is expected to supply electricity under its long-term arrangement with Assam’s power distribution utility.
The scale of the investment means execution will be closely tied to construction progress, equipment deployment, fuel arrangements and transmission infrastructure.
If the scheduled phases proceed as planned, the Chapar plant will add a substantial amount of new generation capacity to Assam’s electricity system by the early 2030s.
For now, the foundation stone marks the transition from the project’s planning and investment stage to physical construction.
