Jindal Group Press Release September 25, 2026 JSW Energy Secures Turbine-Generators for Entire 3,200 MW Salboni Thermal Project with 1,600 MW Phase-II Order with Toshiba JSW Mumbai, India — September 25, 2026 – JSW Thermal Energy Limited (“JSW Thermal”), a wholly owned subsidiary of JSW Energy Limited (“the Company”) has entered into a contract with its associate company, Toshiba JSW Power Systems Private Ltd (“Toshiba JSW”) for the procurement of two steam turbine generators (TG) of 800 MW each for Phase 2 of its Salboni Thermal Project in West Bengal. With this order, the Company has completed the placement of turbine-generator equipment orders for the entire 3,200 MW (4 x 800 MW) Salboni Thermal Power Project (Salboni TPP), following the earlier order for Phase 1 (2 x 800 MW) units. The turbine-generator package will be manufactured and supplied in line with the project’s construction schedule, supporting timely completion and commissioning of the plant. By sourcing key equipment through an associate company, the Company aims to enhance supply- chain certainty, improve coordination during execution, and reduce risks arising from industry- wide equipment shortages. JSW Energy currently has an installed thermal generation capacity of 5,958 MW and 5,000 MW under construction capacity, comprising 3,200 MW at Salboni and 1,800 MW at JSW Mahanadi Power Company Limited (JMPCL). Mr. Sharad Mahendra, Joint Managing Director and CEO of JSW Energy “Our second turbine generator contract with Toshiba JSW fully secures the TG requirement for the entire 3,200 MW at Salboni, our largest single-location thermal asset, and keeps both phases firmly on track for timely completion at a time when critical equipment supply remains tight. This builds on our partnership with Toshiba, which dates back to 2008, and on JSW Energy's clear right to win in thermal power: proven delivery of large sized thermal projects, a healthy balance sheet, and early securing of fuel, land, and key equipment. Salboni TPP will provide reliable baseload power alongside India's renewable expansion, and it contributes directly to the nation's roadmap of adding nearly 100 GW of thermal capacity for Atmanirbhar Bharat.” JSW Energy has a total locked-in generation capacity of 32.4 GW — comprising 15.0 GW operational and 13.4 GW under construction across thermal, hydro, and renewables — along with a pipeline of 4.0 GW. Locked-in energy storage capacity stands at 29.6 GWh, comprising 26.4 GWh of pumped hydro storage and 3.2 GWh of battery energy storage — positioning the Company to supply firm, round-the-clock power as the sector shifts from energy to dispatchability.
