NTPC Renewable Energy, a wholly-owned subsidiary of NTPC Limited, has issued a request for proposals from developers to build interstate transmission system (ISTS)-connected energy storage systems with a capacity of 3,000 MWh and a minimum capacity of 500 MW anywhere in India. NTPC aims to use the energy storage installations to meet its round-the-clock (RTC) renewable energy requirement with a wind-solar profile under the service model. The bid submission deadline is March 11, 2022.
According to the reports, NTPC will enter into an annual fixed charge energy storage service agreement with the selected bidders for a period of 25 years, based on the terms and circumstances of the request for selection. The projects will be constructed on a build, own, and operate basis. The project’s renewable energy will be used to charge the energy storage project. To meet their RTC obligations, NTPC Renewable Energy will use the energy storage facility on a demand basis during peak and off-peak hours.
Prior to this, NTPC Limited issued a request for proposals for the development of 900 MW of solar parks in the Republic of Cuba. NTPC and Union Electrica de Cuba (UNE) would collaborate on the development of 900 MW solar PV parks in Cuba. This 900 MW project, part of Cuba’s 2,100 MW solar project implementation target, aims to significantly reduce greenhouse gas emissions. The annual generation per MW is expected to be 2,400 MWh.
Earlier this month, Fluence, a global market leader in energy storage products, services and ReNew Power announced a partnership to form a new company to meet the needs of local customers across India and to address the country’s rapidly growing energy storage market. The joint venture is expected to start operations by the first half of 2022. The 50:50 joint venture between ReNew Power and Fluence would serve a market that is expected to reach 27GW/108GWh by 2030 according to Central Electricity Authority estimates.
