NTPC Renewable Energy, a wholly-owned subsidiary of NTPC Limited, has invited bids for the development package (Balance of System with land) of the interstate transmission system (ISTS)-connected wind energy projects up to the capacity of 720 MW. The projects can be developed anywhere in India.

The scope of work includes design, engineering, manufacturing, supply, erection, testing, commissioning, and providing the guaranteed parameters for installation of the wind farm starting from 33 kV internal evacuation lines from the unit substation, pooling substation, central monitoring, and control station, reactive power compensating devices, and external transmission line until the ISTS substation.

The offered project by the bidder should be compatible with the installation of any wind turbine generator of size ranging from 2.7 MW to 3.6 MW.

The last date to submit the bids is March 4, 2022. Bids will be opened on the same day.

The bidder will have to submit an amount of ₹10 million (~$134,033) for 20-37 wind turbine generators locations, ₹20 million (~$268,065) for 38-93 wind turbine generator locations, ₹50 million (~$670,163) for 94-186 wind turbine generator locations, and ₹100 million (~$1.34 million) for 187-200 wind turbine generator locations.

To participate in the bidding process, the bidder should have designed, supplied, supervised erection, and commissioned BoS of wind power projects of cumulative capacity of 40 MW or higher at a single location. Out of the total capacity, one project should have been of 10 MW or higher capacity at a single site with the associated civil and electrical works.

Alternatively, the bidder should be a developer of grid-connected wind power projects of cumulative capacity of 40 MW or higher capacity, out of which one project should have been of 10 MW or higher capacity at a single location. The reference project of 10 MW or higher capacity must have been in successful operation for at least one year before the bid opening date.

Also, the bidder should have executed in the last ten years an industrial project either as a developer or engineering, procurement, and construction (EPC) contractor in the areas of power, steel, oil and gas, petrochemical, and any other process industry of a minimum value of ₹400 million (~$5.36 million) for the total quoted capacity of 50 MW to 300 MW and ₹800 million (~$10.72 million) for the total quoted capacity of more than 300 MW.

The bidder should have executed at least one electrical substation of 33 kV or above voltage level, consisting of equipment such as 33 kV or above voltage level circuit breakers and power transformer either as a developer or an EPC contractor. The project should have been in successful operation for at least one year before the bid opening date.

The bidder’s average annual turnover in the last three financial years should not be less than ₹400 million (~$5.36 million) for the quoted capacity of 50 MW to 300 MW and ₹800 million (~$10.72 million) for the quoted capacity of more than 300 MW.

The bidder should have a positive net worth as on the last day of the preceding financial year.

NTPC has stated that any bidder from a country that shares a land border with India will be eligible to bid in this tender only if the bidder is registered with the competent authority.

This month, NTPC invited bids for a BoS package with land for up to 1,000 MW of ISTS-connected solar projects to be set up anywhere in India.

Earlier, NTPC Renewable Energy invited bids for a BoS package for 325 MW of solar projects located at the Shajapur Solar Park in Madhya Pradesh.
