NTPC Renewable Energy (NTPC REL) in India has announced bids for the establishment of 1,200 MW interstate transmission system (ISTS)-connected solar power projects incorporating a 600 MW/2,400 MWh (600 MW x 4 hours) energy storage system (ESS). The deadline for bid submissions is March 13, 2025, with bids opening the same day. Bidders are required to provide an earnest money deposit (EMD) of ₹1.63 million (~$19,845.55)/MW alongside a bid document fee of ₹22,500 (~$272.73). The project, to be executed on a build-own-operate (BOO) basis, can be situated anywhere in India, offering flexibility in project locations. Bids must have a minimum capacity of 50 MW that can be increased in increments of 10 MW. A single bidder can secure a maximum capacity of 600 MW, along with a 300 MW/1200 MWh ESS. The tender specifies that a minimum of 0.5 MW/2 MWh of energy storage capacity must be installed for every 1 MW of solar capacity. Small and Micro Enterprises are exempt from EMD and document costs. Additionally, NTPC Green Energy recently released a tender for a green hydrogen generation unit/electrolyzer for a 1 MW green hydrogen mobility project in Kandla, Gujarat. NTPC has also sought bids for a battery energy storage system pilot project in Dadri, Uttar Pradesh, and for procuring biomass pellets at its Dadri thermal power plant. Moreover, in 2024, NTPC REL invited bids for wind turbine generators for a 960 MW ISTS-connected wind energy project in Karnataka. This move underscores NTPC's commitment to advancing clean energy solutions like solar, green hydrogen, battery storage, and wind energy projects.
