Guwahati, September 21, 2026: Assam Chief Minister Himanta Biswa Sarma has laid the foundation stone for Adani Power Limited’s 3,200 MW ultra-supercritical thermal power plant at Chapar in Dhubri district, marking the beginning of one of the largest power-sector investments in the state. The project involves an estimated investment of ₹48,000 crore and is expected to significantly expand Assam’s power-generation capacity.
The proposed plant will consist of four units of 800 MW each and will use ultra-supercritical technology. According to Adani Power, the facility is designed with high-efficiency systems and modern environmental safeguards. Commissioning is planned in phases beginning from December 2030.
The Chapar project is being positioned as a major addition to the energy infrastructure of Northeast India. Once commissioned, the plant is expected to become the region’s largest power-generation asset and provide electricity for household, commercial and industrial requirements in Assam.
The project is part of a larger ₹63,000-crore power investment programme in Assam involving the Adani Group. Besides the thermal plant, around ₹15,000 crore has been earmarked for two pumped-storage projects with a combined capacity of 2,700 MW through Adani Green Energy.
The investment is also expected to have a significant employment impact. Adani Power estimates that the Chapar project could generate up to 20,000 jobs during the construction phase and approximately 5,000 jobs once the plant becomes operational. The project is also expected to create opportunities for contractors, suppliers, transport operators and other local service providers.
Speaking at the foundation ceremony, Chief Minister Himanta Biswa Sarma described the project as an important development for Assam's emerging energy sector. He said the investment would contribute to employment generation, economic activity and state revenues while creating opportunities for local industries and enterprises.
Adani Group Director Jeet Adani said the project would support homes, businesses and industries by adding reliable power-generation capacity. He also highlighted the potential for local businesses to participate in the project's supply and services ecosystem as construction progresses.
The project follows Adani Power's successful bid in a competitive process conducted in 2025. The company emerged as the successful bidder in October 2025 to establish the 3,200 MW facility and subsequently received the Letter of Award from Assam Power Distribution Company Limited (APDCL) in November 2025.
The proposed investment forms part of a broader expansion of the Adani Group's presence in Assam. Across different sectors, the group has committed investments exceeding ₹80,000 crore, including projects in power, aviation and cement. The group's Terminal 2 at Lokpriya Gopinath Bordoloi International Airport in Guwahati became operational in February 2026.
The Chapar project also comes at a time when Assam is seeking to strengthen its industrial and infrastructure base. A larger and more reliable electricity supply can support energy-intensive industries, commercial establishments and expanding urban and rural demand. The availability of power infrastructure is also an important consideration for businesses assessing future investments in the Northeast.
The project will use ultra-supercritical technology, which operates at higher temperatures and pressures than conventional subcritical coal-fired generation and can achieve higher thermal efficiency. The company has said the plant will incorporate modern environmental safeguards, although the project's eventual environmental performance will also depend on its implementation and regulatory compliance.
With construction now set to move forward, the ₹48,000-crore Chapar thermal power project represents a major infrastructure undertaking for Assam. Its progress over the coming years will be closely watched for its impact on electricity generation, employment, local business participation and the wider industrial development of the state.
