NTPC Limited has awarded Battery Energy Storage System (BESS) engineering, procurement and construction (EPC) contracts to three listed companies across five thermal power stations, with a total value exceeding ₹1,391 crore (excluding taxes). The awards, dated March 28, 2026, were disclosed to stock exchanges on March 29, 2026.
The contracts form part of NTPC’s broader strategy to integrate energy storage into its thermal power infrastructure, supporting grid stability and enabling higher renewable energy penetration.
Project Allocation and Contract Scope
Enviro Infra Engineers Limited (EIEL) won a Letter of Award worth ₹664.33 crore (not including GST) to set up BESS at the Kudgi Super Thermal Power Station in Karnataka and the Ramagundam Super Thermal Power Station in Telangana. The scope includes EPC supply and services, as well as full annual maintenance after performance testing. The project will take 18 months to finish, and the maintenance will last for 11 years. This project is EIEL’s first step into grid-scale energy storage, which is different from its usual business of building water and wastewater infrastructure.
Solarworld Energy Solutions Limited was awarded a Letter of Award valued at ₹314.26 crore (excluding taxes) for a BESS project at Solapur Super Thermal Power Station in Maharashtra (Lot-1). The project involves a capacity of 132 MW / 264 MWh and is scheduled for completion within 15 months.
