NTPC has issued a call for bids for the supply, installation, commissioning, and integration of a 600 kW/3000 kWh Vanadium Redox Flow Battery (VRFB) storage system at the NTPC Energy Technology Research Alliance (NETRA) facility in Greater Noida. This project is a significant step towards enhancing energy storage capabilities and advancing renewable energy solutions. Unlike conventional batteries, VRFB systems store energy in liquid electrolytes that flow through the system, offering distinct advantages in efficiency and longevity. The scope of work for this project encompasses a comprehensive range of tasks, including design, detailed engineering, procurement, fabrication, supply, and erection, along with quality and performance tests. Interested bidders must submit their bids by July 8, 2024, with the bid opening scheduled for the following day. A bid security amounting to ?2 million (~$24,000) is mandatory. Eligible bidders must demonstrate a proven track record in designing and commissioning VRFB systems with a cumulative capacity of 2400 kWh over the past decade. Additionally, at least one reference project must have a minimum capacity of 400 kWh and have been operational for at least six months prior to the bid opening date. Alternatively, bidders can opt for the EPC route, provided they partner with a qualified VRFB manufacturer. These bidders must have completed grid-connected or off-grid solar-battery energy storage projects on an EPC basis within the last ten years, with at least one project valued at a minimum of ?114 million (~$1.43 million). The reference project should have also been operational for at least six months before the bid opening date. Financial criteria for participation include an average annual turnover of no less than ?143 million (~$1.79 million) over the preceding three financial years and a net worth of at least 100% of the paid-up share capital as of the last financial year's end. This initiative follows NTPC's recent invitation for bids to develop a 250 MW/500 MWh standalone Battery Energy Storage System (BESS) at its thermal power stations in Gadarwara and Solapur. Furthermore, in December, NTPC Renewable Energy awarded Jayram Industries India a contract to commission a 250 kW/1,200 kWh BESS for supporting solar power projects at the Khavda Renewable Energy Park in Gujarat. NTPC's ongoing efforts underline its commitment to pioneering advanced energy storage solutions and integrating sustainable energy technologies into its operations.
