NTPC Renewable Energy has issued a request for proposals for balance of system (BoS) package for a 500 MW state transmission utility (STU) linked solar project in Bhadla, Rajasthan. The project excludes the setup of land and transmission system and supply of solar modules.
According to the tender guidelines, the scope of work under the project includes designing, engineering, manufacturing, provision, packing and forwarding, transportation, unloading, storage, installation, testing, and commissioning. The scope also includes the responsibility to provide boundary fenced land and developing the transmission line to the nearest STU substation. The selected bidder will be tasked with site preparation, which involves leveling the ground, removing vegetation, and, if desired, conducting topographical surveys and geotechnical assessments of the project site. Furthermore, the bidder is accountable for designing and building the foundation, as well as erecting the mounting structure based on single axis tracker technology for the installation of solar photovoltaic panels. Moreover, the bidder is required to secure power and water supply for construction activities and handle all relevant electrical and civil tasks essential for grid integration. This encompasses installing transformers, panels, protective systems, cables, metering at the 33 kV level, and conducting grid compliance assessments in accordance with regulatory requirements. The bidder will also be tasked with providing and installing suitable reactive compensation equipment to guarantee adherence to dynamic reactive power compensation standards at the point of interconnection at the STU end. The bid submission deadline is May 1, 2024.
NTPC REL intends to fund the specified package either through its own funds or through borrowing. The bidder must be either a developer or have experience in designing, supplying, overseeing erection, and commissioning of the remaining components of solar-based grid-connected power projects, with a combined installed capacity of 40 MW or more. Of these, at least one project must possess a capacity of 10 MW or greater. The specified reference project with a capacity of 10 MW or more should have been operating successfully for a minimum of six months prior to the bid opening date. Alternatively, within the past decade, the bidder should have completed an industrial project as either a developer or an engineering, procurement, and construction (EPC) contractor in sectors such as power, steel, oil and gas, petrochemical, fertiliser, cement, coal mining, including coal handling plant, or any other process industry, with a value of Rs 1.28 billion or higher, either as a single project or single work. The project must have been successfully operational for a minimum of one year or six months preceding the bid opening date. Furthermore, the bidder must have completed at least one electrical substation with a voltage level of 33 kV or higher, comprising components like circuit breakers and power transformers of 33 kV or higher voltage level, either as a developer or an EPC contractor. The substation must have been successfully operational for a minimum of one year or six months preceding the bid opening date.
