NTPC Limited, on behalf of NTPC (Mauritius) Energy Limited, has invited international competitive bids for a 15 MW floating solar photovoltaic (PV) project integrated with a 12 MW/60 MWh battery energy storage system (BESS) at Tamarind Falls Reservoir in Mauritius. The tender covers an engineering, procurement and construction (EPC) package for developing the grid-connected floating solar power plant and its associated battery storage facility.
The project aims to combine floating solar power generation with battery storage to support electricity supply reliability and firm power dispatch. According to the tender specifications, the floating solar installation must maintain a minimum DC-to-AC ratio of 1.33. The integrated BESS is specified with a power capacity of 12 MW and an energy storage capacity of 60 MWh.
The EPC package includes the design, engineering, manufacturing, supply, transportation, storage, installation, testing and commissioning of the floating solar PV plant and BESS. The scope also includes three years of operation and maintenance (O&M) for the solar plant, an annual maintenance contract (AMC) for critical equipment, and a 12-year comprehensive annual maintenance contract (CAMC) for the battery energy storage system.
