Tata Power has invited bids to develop and procure power from 225 MW of grid-connected intrastate and interstate wind-solar hybrid power projects with a greenshoe option of an additional capacity of 225 MW on a long-term basis.

The last date to submit the bids online is July 31, 2023. Bids will be opened on August 2.

Bidders will have to submit ₹300,000 (~$3,661) plus applicable GST as a bid processing fee and an amount equivalent to ₹500,000 (~$6,101)/MW/project as an earnest money deposit.

The successful bidder must furnish an amount equivalent to ₹1 million (~$12,201)/MW/project at least two days before signing the power purchase agreement (PPA) as a performance bank guarantee.

Tata Power-Distribution will enter into a PPA with the successful bidders for 25 years from the commissioning date of the project.

The minimum project size for an intrastate hybrid power project must be 25 MW, with at least 10 MW at one site. The minimum project size for interstate projects must be 50 MW at one site, which should be interconnected to a single delivery point.

Only commercially established and operational technologies can be used to minimize the technology risk and to achieve the timely commissioning of the projects. Already commissioned wind or solar power projects are not eligible to participate in this tender.

To be eligible, the net worth of bidders should be equal to or greater than ₹10 million (~$122,005)/MW of the quoted capacity as of the last day of the previous financial year.

To ascertain that the bidder has sufficient means to manage the fund requirements for the project, the bidder will be required to demonstrate at least one of the following parameters:

• The minimum annual turnover of bidders should be at least ₹7.5 million (~$91,504)/MW of the quoted capacity per the latest audited financial documents.
• The internal resource generation capability, in the form of Profit Before Depreciation, Interest, and Taxes (PBDIT), should be at least ₹1.5 million (~$18,301)/MW of the quoted capacity.
• Bidders should have an in-principle approval letter from the lending institutions committing a line of credit for a minimum amount of ₹1.875 million (~$22,876)/MW of the quoted capacity toward meeting the working capital requirement of the project.

Only type-certified wind turbine models listed in the Revised List of Models and Manufacturers (RLMM) issued by the Ministry of New and Renewable Energy (MNRE) will be allowed for deployment under this tender.

Additionally, Tata Power has mandated the use of solar modules listed in the Approved List of Models and Manufacturers (ALMM) issued by MNRE for the projects.

The transmission of power up to the delivery point, including absorbing transmission losses and energy accounting infrastructure, will be the responsibility of the hybrid power developer at his own cost.

The hybrid power developer must maintain generation to achieve an annual capacity utilization factor (CUF) of not less than 90% of the declared value and not more than 120% of the declared CUF value during the PPA duration of 25 years.

In March this year, Tata Power Renewable Energy, a subsidiary of Tata Power, signed a PPA with Tata Power Delhi Distribution, a joint venture between Tata Power and the government of Delhi, for supplying 510 MW of wind-solar hybrid power. The PPA comprised 170 MW of solar and 340 MW of wind power.
