The last date for the submission of bids is December 4, 2023


NTPC Renewable Energy (NTPC REL), a wholly owned subsidiary of NTPC, has invited bids for the balance of the system package for the 1,080 MW Inter-State Transmission System (ISTS)-connected wind energy project in Karnataka.

The last date for the submission of bids is December 4, 2023. Bids will be opened the same day.

The scope of the work includes design, engineering, micro-sitting, manufacturing, supply, erection, testing, commissioning, and proving the guaranteed performance parameters for installation of the substation, central monitoring and control station, wind monitoring masts, external EHV transmission line till Gadag-II ISTS substation, etc.

The wind BOS development package does not cover the provision of wind turbine generators (WTG), civil construction, or the installation of unit substations and Supervisory Control and Data Acquisition (SCADA) systems.

The project must be designed to accommodate WTGs of varying sizes, starting from 2.7 MW, and capable of accommodating larger WTG models available in the market. These WTGs must be listed in the Ministry of New and Renewable Energy’s latest Revised List of Models & Manufacturers.

The selected bidder will also be responsible for a three-year, comprehensive operation and maintenance commitment within the Wind BOS development package.

This includes overseeing the pooling substation, internal and external transmission systems, and the supply of all necessary spare parts and consumables. Additionally, they are responsible for conducting repairs or replacements of any faulty equipment and covering expenses related to reactive power penalties and any other charges imposed by the respective state government.

Bidders must submit ₹22,500 (~$270) as the cost of the bidding document.

They should have a track record of executing wind projects with a cumulative capacity of 40 MW or more, including at least one project with a 10 MW or higher capacity. They must be capable of arranging land for the wind energy project and conducting micro-siting for wind turbines.

The bidders can qualify if they have experience as a developer of grid-connected wind power projects with a cumulative installed capacity of 40 MW or more, with at least one project having a 10 MW or higher capacity at a single location. This reference project of 10 MW or higher capacity must have successfully operated for at least six months before the bid opening date.

Alternatively, the bidders should have executed an industrial project in the last ten years, either as a developer or an engineering, procurement, and construction (EPC) contractor, in sectors such as power, steel, oil and gas, petrochemical, fertilizer, cement, or any other process industry.

This project should be either a single project and should have been in successful operation for at least one year or six months before the bid opening date.

Bidders must have experience executing at least one electrical substation with a 33 kV or higher voltage level, including equipment such as 33 kV or above voltage level circuit breakers and power transformers.

This experience can be as a developer or an EPC contractor, and the project should have been in successful operation for at least one year or six months before the date of the techno-commercial bid opening. The minimum required duration for electrical substations is at least one year for projects outside the renewable energy (RE) sector (e.g., solar/wind) and at least six months for electrical substations in RE projects.

The bidders must have a minimum average annual turnover as follows:

  • For projects with a quoted capacity ranging from 50 MW to 300 MW, the average annual turnover should not be less than ₹520 million (~$6.2 million).
  • For projects exceeding 300 MW in capacity, the average annual turnover should be at least ₹1.73 million (~$20,794)/MW for any three financial years out of the preceding five financial years as of the bid opening date.

Earlier, NTPC Renewable Energy had issued an invitation for bids for the design, engineering, manufacturing, supply, installation, and commissioning of a 250 MW/500 MWh grid-connected standalone battery energy storage system (BESS) near Fatehgarh-III ISTS substation in Rajasthan.
