Assam Chief Minister Himanta Biswa Sarma laid the foundation stone on 20 September 2026 for Adani Power's 3,200 MW coal fired plant at Chapar in Dhubri district. This project represents the largest proposed power asset in the state but the first 800 MW unit is not expected to be commissioned until December 2030. Site development has moved past the initial tender stage following an award in November 2025 according to project reporting by the Economic Times. The central government granted environmental clearance for the facility on 14 July 2026 after review by the Ministry of Environment, Forest and Climate Change. The plant will consist of four separate 800 MW units utilising ultra-supercritical technology. Each unit will go live at intervals of approximately six months after the first one launches in December 2030 as noted in reporting by The Sentinel. The project spans 585 hectares of land across the villages of Charuabakhra, Santoshpur and Chirakuta I and II.
Assam Power Distribution Company Limited selected Adani Power through a competitive bidding process with a quoted tariff of ₹6.30 per kilowatt hour. The Assam Electricity Regulatory Commission approved this rate after comparing it to the ₹6.64 per unit cost from the Bongaigaon station and another procurement at ₹6.58 per unit, as stated by The Sentinel. Local generation aims to avoid interstate transmission charges and losses. Environmental clearance records show an annual coal requirement of roughly 13.27 million tonnes alongside expected ash generation of 5.31 million tonnes. Water intake is projected at 153,600 cubic metres daily drawn from the Brahmaputra river. All coal transport must rely on rail via a dedicated siding connected from Bilasipara according to official records from the
Ministry of Environment, Forest and Climate Change. The site sits roughly 5 km from the Chakrashila Wildlife Sanctuary and about 2.02 km from its designated eco-sensitive zone. Project operators must maintain a zero liquid discharge system and use high-efficiency electrostatic precipitators. They are also required to monitor the Mar Gaurang Nala biodiversity and conduct annual water audits.
The development follows a design build finance own operate model where Adani owns the asset and APDCL serves as the buyer. Financing for coal was secured under the Centre's SHAKTI policy. The company estimated a project cost of ₹48,000 crore in its November 2025 disclosure. Assam's Thermal Power Generation Promotion Policy 2025 provides significant support for such projects. It targets 2,000 MW of new capacity by 2030 and 5,000 MW by 2035 according to the
Government of Assam. The state may lease land for 35 years at a token rate of ₹1 per bigha annually and may consider taking a 27 percent stake in the project. Company officials have cited varied employment projections. Jeet Adani claimed that 4,500 youth from Assam have already been hired through recruitment drives but it remains unclear how many of these roles are specifically tied to this project versus other group interests. Early estimates suggested the plant could create 20,000 jobs during construction and 5,000 roles during operations as reported by ET Energyworld. Future progress will depend on concrete milestones such as land handover, site grading and final boiler and turbine orders. The first critical delivery check point is set for December 2030.
