NTPC Renewable Energy, a wholly owned subsidiary of NTPC, has invited bids for the balance of system package (BoS) for a 1,000 MW inter-state transmission system (ISTS)-connected wind energy project at Solapur in Maharashtra.

The last date for submitting bids is March 15, 2024. Bids will be opened on the same day.

The scope of the work involves the design, engineering, micro-siting, manufacturing, supply, erection, testing and commissioning, and proving the guaranteed performance parameters for installation of the project starting from 33kV internal evacuation lines from the unit substation, pooling substation, central monitoring, and control station (CMCS), wind monitoring masts, and external EHV transmission lines until the ISTS substation.

The wind BoS package does not include the provision, construction, and setup of wind turbine generators , unit substations, and supervisory control and data acquisition.

Bidders have to submit ₹22500 (~$271.16) as cost of the bidding documents.

They must have undertaken the following tasks for wind projects with a combined capacity of 40 MW or more, including at least one wind project with a capacity of 10 MW or higher:

• Securing land for the wind energy project
• Micro-siting of wind turbines.

Alternatively, bidders must have developed grid-connected wind projects with a cumulative installed capacity of 40 MW or more, including at least one project of 10 MW or higher capacity at a single location.

The specified reference project of 10 MW or higher must have been in operation for a minimum of six months before the date of bid opening.

In the last ten years, bidders should have executed an industrial project, either as developers or EPC contractors, in sectors such as power, steel, oil and gas, petrochemical, fertilizer, cement, or any other process industry.

The project should meet the minimum financial criteria specified below and have been in  operation for at least one year or six months before the date of bid opening:

• The minimum financial figure for the total quoted capacity from 50 MW to 300 MW should be ₹690 million (~$8.3 million)/MW
• For projects more than 300 MW, the minimum financial figure should be ₹2.3 million (~$27,710.35)/MW

Bidders must demonstrate a track record of at least one year of operation for industrial projects in sectors other than the renewable energy.

For projects in the renewable energy sector (solar/wind), a minimum of six months of  operation is required.

Additionally, bidders should have successfully executed at least one electrical sub-station with a voltage level of 33kV or above. This sub-station should include equipment such as circuit breakers and power transformer at the specified voltage level. The sub-station must have been in operation for at least one year or six months before the date of bid.

Bidders must possess a positive net worth as of the final day of the previous financial year.

NTPC Renewable Energyhad invited bids for the selection of hybrid power generators for the supply of 1,000 MW power from ISTS-connected wind-solar hybrid projects anywhere in India under Tranche-V.

Recently, NTPC invited bids to set up 1,500 MW of ISTS-connected solar power projects across India.
