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

The successful bidder will also have to take care of the comprehensive operation and maintenance of the system for three years.

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 guaranteed performance parameters starting from 33kV internal evacuation lines from the unit substation, pooling substation, central monitoring and control station, wind monitoring masts, and external EHV transmission line until the ISTS substation.

The last date to submit the bids is February 28, 2023. Bids will be opened on the same day.

Bidders should have executed wind projects of cumulative capacity of 40 MW or higher, out of which at least 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 operation for at least one year before the bid opening date.

Alternatively, bidders should have executed in the last ten years an industrial project either as a developer or an EPC contractor in the area of power, steel, oil & gas, petrochemical, fertilizer, cement, or any other process industry of a minimum value of ₹400 million (~$4.94 million) for a total quoted capacity of 50 MW to 300 MW and ₹1.4 million (~$17,286)/MW for quoted capacity more than 300 MW.

They 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, which should have been in operation for at least one year before the bid opening date.

The average annual turnover of bidders in any three of the last five financial years should not be less than ₹400 million (~$4.94 million) for quoted capacity in the range of 50 MW to 300 MW and ₹1.4 million (~$17,286)/MW for quoted capacity of more than 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 its paid-up share capital.

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

NTPC has stated that the offered wind project by the bidder should be compatible with the installation of any wind turbine generator of size ranging from 2.7 MW or higher. The wind turbine generators should be from the Revised List of Models and Manufacturers issued by the Ministry of New and Renewable Energy.

Last November, NTPC Renewable Energy invited bids for the BoS package to set up ISTS-connected wind power projects of 1,000 MW capacity in Karnataka.

Earlier, NTPC Renewable Energy had invited bids to set up 100 MW of state transmission utility (STU)-connected wind power projects in Madhya Pradesh.
