The foundation stone has been laid for Adani Power Limited’s 3,200 megawatt Ultra-Supercritical Thermal Power Plant at Chapar in Dhubri district, involving an investment of about ₹48,000 crore. The project will have four units of 800 megawatts each and is scheduled to be commissioned in phases from December 2030, with full commissioning targeted by December 2032.

What is the project?

The project emerged from a competitive bidding process conducted by Assam Power Distribution Company Limited, which awarded the long-term electricity procurement contract to Adani Power. The project follows a Design, Build, Finance, Own and Operate model.

The plant will use Ultra-Supercritical technology, which operates at higher temperature and pressure than conventional coal-based plants and is designed to achieve higher thermal efficiency.

• The project is expected to create up to 20,000 jobs during construction and around 5,000 jobs after commissioning.
• It is expected to create opportunities for local contractors, suppliers, transport operators and service providers.
• Assam Electricity Grid Corporation Limited is separately developing transmission infrastructure to evacuate the 3,200 megawatts generated at Chapar.

Why is it important for Assam?

• Assam has historically depended significantly on purchased electricity to meet its growing demand. 
• The new capacity is intended to strengthen the state’s energy security and support industrial expansion.
• The project is part of a larger ₹63,000-crore power investment proposed by the Adani Group in Assam, comprising the Chapar thermal plant and two Pumped Storage Plants with a combined capacity of 2,700 megawatts.

Operates under the broader energy framework

The electricity procurement was initiated by Assam Power Distribution Company Limited, while transmission evacuation is being taken up by Assam Electricity Grid Corporation Limited. At the national level, the project is also linked to India’s coal-based power expansion and environmental clearance framework under the Environment Impact Assessment Notification, 2006. The project has been appraised as a Category A project at the central level.

Key objectives

• The project aims to increase Assam’s domestic power-generation capacity and reduce dependence on electricity purchased from outside the State.
• It is expected to provide a more reliable electricity base for households, businesses and industries.
• It can support Assam’s broader industrialisation and employment generation by improving the availability of power.
• The project is also expected to stimulate local supply chains and ancillary economic activity.

Key Takeaway

The Chapar project illustrates the link between energy security, industrialisation, infrastructure and employment. At the same time, because it is a large coal-based thermal power project, its development must be balanced with environmental safeguards, efficient technology, emissions management and India’s broader transition towards cleaner energy.

Prelims Fact: The Chapar plant will comprise four 800-megawatt units, giving a total installed capacity of 3,200 megawatts.
