NTPC Renewable Energy, a wholly-owned subsidiary of NTPC, has invited bids for the balance of system (BoS) package to set up interstate transmission system (ISTS)-connected wind power projects of 1,000 MW capacity in Karnataka.

The scope of work includes the design, engineering, manufacturing, supply, erection, testing, and commissioning of the wind projects. The contractor will also be responsible for proving the performance parameters starting with the 33 kV internal evacuation lines from the unit substation, pooling substation, reactive power compensating devices, wind monitoring masts, and external EHV transmission line to the ISTS substation.

The successful bidder will also be responsible for the comprehensive operation and maintenance of the complete system for three years under the wind BOS development package scope.

The last date to submit the bids is December 19, 2022. Bids will be opened on the same day.

The offered wind project by the bidder must be compatible with the installation of any wind turbine generator (WTG) of size ranging from 2.7 MW to larger WTG machine size as available in the market. The WTG machine must be listed in the Revised List of Models and Manufacturers of Wind Turbines.

Bidders should have executed wind projects as engineering, procurement, and construction (EPC) contractors or developers of a cumulative capacity of 40 MW or higher. At least one wind project should be of 10 MW or higher capacity and have been in operation for a year before the bid opening date.

Alternatively, bidders should have in the last ten years executed an industrial project either as EPC contractors or developers in the area of power, steel, oil & gas, petrochemical, fertilizer, cement, or any other process industry of a minimum value of ₹400 million (~$4.9 million) for quoted capacity of 50 MW to 300 MW and ₹1.4 million (~$17,150)/MW for over 300 MW. The project should have been operating for at least one year before the bid opening date.

Bidders should have executed at least one electrical substation of 33kV or above voltage level, consisting of equipment such as 33kV or above voltage level circuit breakers and a power transformer. The project should have been in operation for at least one year prior to the bid opening date.

The average annual turnover of bidders should not be less than ₹400 million (~$4.9 million) for quoted capacity of 50 MW to 300 MW and ₹1.4 million (~$17,150)/MW for quoted capacity of over 300 MW.

If bidders do not satisfy the annual turnover criteria on their own, their holding companies can meet the stipulated turnover requirements, provided that the net worth of the holding company as of the last day of the preceding financial year should be equal to or more than the paid-up share capital of the holding company.

Bidders should have a positive net worth as of the last day of the preceding financial year.

In May this year, NTPC Renewable Energy invited bids to set up 100 MW of state transmission utility-connected wind energy projects in Madhya Pradesh.

Earlier, NTPC Renewable Energy had invited bids for the development package (BoS with land) of the ISTS-connected wind energy projects of up to 720 MW.
