CESC Green Power, the renewable energy subsidiary of Kolkata-based Calcutta Electric Supply Corporation (CESC), has received in-principle approval from Odisha’s High-Level Clearance Authority (HLCA) for a massive ₹4,500 crore ($540 million) investment in solar and battery manufacturing facilities, marking a significant expansion in India’s clean energy manufacturing landscape.

Project Scope and Components
The approved mega-project in Dhenkanal district encompasses a comprehensive renewable energy manufacturing ecosystem that will be developed in three phases. The facility will house a 3 GW solar cell manufacturing unit, a 3 GW solar module production facility, a 5 GWh advanced chemistry battery cell pack and solar components plant, and a 60 MW AC captive power project to support operations.
This integrated manufacturing complex represents one of the largest single investments in Odisha’s renewable energy sector and underscores the state’s emergence as a preferred destination for solar manufacturing investments.
Strategic Expansion of CESC’s Manufacturing Footprint
The Odisha project significantly expands CESC’s renewable energy manufacturing capabilities beyond its existing facilities. The company has already commissioned a 1 GW solar module manufacturing site in Jaipur, Rajasthan, and established a 3 GW solar cell manufacturing unit in the Yamuna Expressway Industrial Development Area in Uttar Pradesh.
“This development marks a significant expansion of CESC’s footprint in solar and battery storage manufacturing,” industry analysts note, highlighting the strategic importance of vertical integration in India’s rapidly growing solar sector.
Financial Backing and Implementation
CESC Limited has committed to providing comprehensive financial support to ensure successful project implementation. The parent company will extend full backing through equity infusion, strategic assistance, and facilitation of institutional funding. This financial commitment includes meeting all financial closure requirements as mandated by the state government.
The investment announcement positively impacted CESC’s market performance, with shares rising 1% to reach a day’s high of ₹174.71 on November 14, following the approval announcement. The company’s strong financial position, with Q2 FY2025-26 consolidated net profit rising 19.3% to ₹445 crore and revenue growing 12% to ₹5,267 crore, provides a solid foundation for this ambitious expansion.
Odisha’s Growing Solar Manufacturing Hub
The approval comes at a crucial time as Odisha positions itself as a major solar manufacturing destination in India. The state’s attractive investment climate, featuring capital subsidies, land banks, port infrastructure, electricity duty waivers, and GST exemptions, has drawn significant investments from major players in the renewable energy sector.
Over the past two years, companies including Waaree Energies, Saatvik Solar, Icon Solar, and Inox Solar have announced manufacturing facilities in the state. However, Odisha faced setbacks when Waaree Energies relocated a portion of its planned investments outside the state, making CESC’s commitment particularly significant for the state’s industrial growth ambitions.
Meeting India’s Solar Manufacturing Goals
The project aligns with India’s ambitious renewable energy targets and the government’s push for domestic manufacturing under the Atmanirbhar Bharat (self-reliant India) initiative. With India targeting 500 GW of renewable energy capacity by 2030, domestic manufacturing capability for solar cells, modules, and energy storage systems has become critical to reduce import dependency and strengthen energy security.
The integration of battery manufacturing alongside solar component production reflects the evolving needs of India’s energy transition, where energy storage solutions are becoming increasingly important for grid stability and renewable energy integration.
Employment Generation and Economic Impact
While specific employment figures for this project haven’t been disclosed, investments of this magnitude typically generate thousands of direct and indirect jobs across manufacturing, logistics, and support services. The project is expected to contribute significantly to Odisha’s industrial output and strengthen its position in India’s renewable energy value chain.
The phased development approach allows for systematic capacity building and market alignment, ensuring sustainable growth while managing capital deployment efficiently.
Technology and Innovation Focus
The inclusion of advanced chemistry battery cell manufacturing indicates CESC’s focus on next-generation energy storage technologies. The 5 GWh battery manufacturing capacity will support both grid-scale storage projects and the growing electric vehicle ecosystem in India.
The integrated nature of the facility, combining solar cell and module production with battery manufacturing, creates synergies in operations and positions CESC to offer comprehensive renewable energy solutions to the market.
Market Outlook and Future Prospects
Industry experts view this investment as a vote of confidence in India’s renewable energy sector and Odisha’s investment climate. With global supply chain realignments and India’s push for manufacturing localization, domestic production capacity for solar components and batteries is expected to see continued growth.
CESC Green Power’s expansion plans align with broader market trends, including increasing demand for domestically manufactured solar modules under India’s Approved List of Models and Manufacturers (ALMM) policy and growing requirements for energy storage in renewable energy projects.
Conclusion
CESC Green Power’s ₹4,500 crore investment in Odisha represents a landmark development in India’s journey toward renewable energy self-sufficiency. As the project progresses through its implementation phases, it will contribute to India’s solar manufacturing capacity, create employment opportunities, and strengthen Odisha’s position as a key player in the country’s clean energy transition.
The successful execution of this project will not only enhance CESC’s market position but also demonstrate the viability of large-scale integrated renewable energy manufacturing in India, potentially attracting more investments to the sector.
