en.Wedoany.com Reported - NTPC Green Energy Limited (NGEL), on behalf of NTPC UP Green Energy Limited (NUGEL), has issued a tender for the development of a 50 MW/200 MWh Battery Energy Storage System (BESS) in Jhansi, Uttar Pradesh.
According to the tender requirements, the BESS must have a design life of 25 years from the date of commissioning, with capacity degradation considered based on the bidder's proposal for a single daily cycle operation. The provided batteries must have a rated cycle life of at least 10,000 cycles.
Previously, NTPC awarded battery energy storage system contracts for its thermal power plants to Pratap Technocrats Pvt. Ltd. and SPML Infra Limited. Pratap Technocrats secured 570 MWh of BESS capacity at the Gadarwara and Khargone thermal power plants. Meanwhile, NTPC awarded a 1 GWh BESS project at the Barauni thermal power station in Bihar to SPML Infra Limited for a contract value of INR 11.28 billion.
Under the scope of work, the selected bidder is required to develop a 50 MW/200 MWh BESS project at NUGEL's Jhansi site in Uttar Pradesh. This includes all activities and services related to the BESS portion, covering equipment supply and engineering execution as specified in the technical specifications. The bidder is responsible for delivering the project to the Point of Interconnection (POI) with the Uttar Pradesh Power Transmission Corporation Limited (UPPTCL) grid, and for the detailed design, capacity determination, supply, installation, integration, testing, and commissioning of the BESS to meet the agreed project performance parameters.
The scope of work is deemed to include all activities, systems, and services necessary to meet the overall project requirements and performance guarantees. The selected developer will be responsible for the design, engineering, supply, packaging, dispatch, transportation, unloading, storage, installation, and commissioning of the grid-connected BESS on a turnkey basis. The bidder is also required to complete unloading, installation, testing, commissioning at the project site, and integrate the BESS with the infrastructure of the solar photovoltaic plant, which is being developed under a separate package, at the 33 kV collector switchgear to commission a fully integrated BESS system connected to both the solar plant and the grid.
The bidder must guarantee a minimum dispatchable capacity of 92% at the POI throughout the 15-year operation period, starting from 100% of the rated dispatchable capacity on the Commercial Operation Date (CoD) and maintaining 95% capacity in the first year. At the time of handover, the dispatchable capacity must not be less than 92%. The bidder's scope also includes comprehensive operation and maintenance services for a period of 15 years, including related warranties, annual maintenance contracts, and insurance coverage for the BESS.
The project must achieve a minimum monthly Round Trip Efficiency (RTE) of 80%, including auxiliary power consumption, measured at the BESS termination point at 33 kV. Monthly system availability must be maintained at 98%, with detailed availability requirements specified in the tender document. The provided BESS capacity must be sufficient to meet the deliverable capacity requirements at the POI, including reactive power compensation requirements. The scope of work also includes conducting grid compliance studies for the integrated solar-plus-storage system; grid study inputs related to the solar plant will be provided by the owner. Any grid compliance studies required for future capacity additions also fall within the bidder's scope. Additionally, the bidder is responsible for providing reactive power compensation and ensuring power quality for the entire BESS system up to the 220 kV grid interconnection point at the UPPTCL switchyard.
