JSW Energy Limited has taken a significant step toward strengthening execution certainty for its upcoming thermal capacity by announcing that its wholly owned subsidiary, JSW Thermal Energy Limited, has entered into a contract with its associate company, Toshiba JSW Power Systems Private Ltd, for the supply of two steam turbine generators of 800 MW each for the 1,600 MW Salboni Thermal Power Project in West Bengal.
The agreement covers the manufacturing and supply of the turbine-generator packages in alignment with the project’s construction schedule, ensuring timely execution and commissioning of one of JSW Energy’s largest thermal projects currently under development.
Strengthening Supply Chain Control and Execution Certainty
By sourcing critical power-generation equipment from an associate company, JSW Energy aims to enhance supply-chain reliability, coordination efficiency, and risk mitigation, particularly at a time when the power sector is witnessing global equipment constraints and long delivery timelines.
The company highlighted that closer integration with Toshiba JSW will help streamline project execution, reduce dependency risks, and ensure better alignment between engineering, manufacturing, and on-site installation activities.
Such strategic sourcing decisions are increasingly important for large infrastructure projects, where delays in key equipment supply can have cascading impacts on project timelines and cost structures.
Salboni Project: A Key Addition to India’s Baseload Capacity
The Salboni Thermal Power Project, with a planned capacity of 1,600 MW, represents a major addition to India’s baseload power infrastructure. Located in West Bengal, the project is expected to play a critical role in supporting grid stability, regional power demand, and energy security, particularly as renewable capacity continues to scale across the country.
Thermal power remains an essential complement to variable renewable energy sources such as solar and wind, providing round-the-clock, dispatchable power that ensures system reliability during periods of low renewable generation.
Expanding JSW Energy’s Thermal Portfolio
JSW Energy currently owns and operates 5,658 MW of thermal generation capacity, powered by a mix of imported and domestic coal. With the 1,600 MW Salboni project under construction and an option to add 1,800 MW at the KSK Mahanadi project, the company’s total thermal capacity is projected to rise to 9,058 MW.
Once commissioned, thermal power will account for approximately 30% of JSW Energy’s total locked-in generation capacity of 30.5 GW, reflecting the company’s strategy of maintaining a balanced and diversified generation mix across thermal, renewable, hydro, and energy storage assets.
Management Commentary
Commenting on the development, Sharad Mahendra, Joint Managing Director and CEO of JSW Energy, said:
“The turbine generator supply contract with Toshiba JSW is a strategic step in strengthening supply-chain control and ensuring execution certainty for our Salboni Thermal Project. Our long-standing association with Toshiba, forged in 2008, is built on shared values of excellence, innovation, and a commitment to long-term value creation, and this contract further reinforces that trusted partnership.”
He added that the Salboni Power Project underscores JSW Energy’s commitment to supporting India’s energy security by adding reliable baseload capacity that complements the country’s expanding renewable footprint.
“As India advances toward its long-term energy transition goals, thermal power will continue to play a vital role in grid stability and system resilience. We are proud to contribute to the nation’s ambitious roadmap of incrementally adding nearly 100 GW of thermal capacity, while building a balanced, secure, and future-ready power system for Atmanirbhar Bharat.”
Broader Capacity and Energy Storage Ambitions
JSW Energy currently has a total locked-in generation capacity of 30.5 GW, comprising:
- 13.3 GW operational capacity
- 12.4 GW under construction across thermal and renewable projects
- 150 MW of hydro capacity under acquisition
- 4.6 GW of pipeline projects
In addition, the company has secured 29.4 GWh of locked-in energy storage capacity, including:
- 26.4 GWh from hydro pumped storage projects
- 3.0 GWh from battery energy storage systems (BESS)
These assets position JSW Energy as one of India’s most diversified power producers, spanning conventional, renewable, and storage technologies.
Long-Term Vision: Balanced Growth and Decarbonisation
While JSW Energy continues to expand its renewable and storage portfolio, the Salboni project highlights the company’s belief in the continued relevance of thermal power as part of a stable and resilient power system. The company has articulated clear long-term goals of achieving 30 GW of generation capacity and 40 GWh of energy storage capacity by FY 2030, alongside its ambition to attain Carbon Neutrality by 2050.
Industry observers note that such a balanced approach—combining renewables, storage, and modern thermal capacity—is critical for managing India’s growing electricity demand while ensuring grid reliability during the energy transition.
