NTPC has invited bids to set up 1,500 MW of interstate transmission system (ISTS)-connected wind-solar hybrid power projects anywhere in India.

The last date to submit the bids online is October 17, 2023. Bids will be opened on the same day.

The minimum capacity of each project at one site must be 50 MW.

Bidders must submit ₹300,000 (~$3,604) + GST as a bid processing fee for capacity up to 50 MW, ₹500,000 (~$6,008) + GST for capacity above 50 MW and up to 100 MW, ₹1 million (~$12,016) + GST for capacity above 100 MW and up to 250 MW,  ₹2 million (~$24,033) + GST for capacity above 250 MW and up to 500 MW, and ₹3 million (~$36,049) + GST for capacity above 500 MW.

Bidders must submit ₹1.16 million (~$13,939)/MW as an earnest money deposit.

The successful bidder must furnish ₹2.9 million (~$34,848)/MW for each project as a performance bank guarantee within 70 days from the date of the issuance of the letter of award or signing of the power purchase agreement (PPA), whichever is earlier.

A PPA will be signed between NTPC and successful bidders subject to the signing of a power sale agreement with the state distribution companies for the identified capacity.

Only commercially established and operational technologies should be used to minimize the technology risk and to achieve timely commencement of power supply from the projects.

To be eligible, the net worth of bidders should be at least ₹11.46 million (~$137,708) /MW of the quoted capacity as of the last day of the previous financial year.

The minimum annual turnover of bidders should be ₹6.15 million (~$73,901)/MW of the quoted capacity during the last financial year.

Bidders should have internal resource generation capability in the form of Profit Before Depreciation, Interest, and Taxes for a minimum of ₹1.23 million (~$14,780)/MW of the quoted capacity as of the last day of the previous financial year.

They should have an in-principle approval letter from the lending institutions committing a line of credit for a minimum of ₹1.54 million (~$18,505)/MW of the quoted capacity toward meeting the working capital requirement.

The responsibility of getting the ISTS connectivity will entirely be on the generator.

Only type-certified wind turbine models listed in the Revised List of Models and Manufacturers should be used for the projects.

Also, NTPC has mandated the use of solar modules from the Approved List of Models and Manufacturers issued by the Ministry of New and Renewable Energy.

The hybrid power generator should maintain an energy supply to achieve an annual supply corresponding to the annual capacity utilization factor (CUF) of not less than 80% of the declared value and not more than 120% of the declared CUF value during the PPA duration of 25 years.

Recently, NTPC invited bids to implement a 120 MW ground-mounted and a 56 MW floating solar project at NTPC Ramagundam Super Thermal Power Plant in Telangana.
