Bids Invited for 255 MW of Wind-Solar Hybrid Projects With Greenshoe Option Across India

Listen to this article

Tata Power Delhi Distribution (TPDDL) has invited bids to set up 255 MW of wind-solar hybrid power projects with a greenshoe option of an additional 255 MW across India. The projects will be developed on a build, own, and operate basis.

The last date to submit the bids is October 31, 2022. Bids will be opened the following day.

Bidders will have to submit ₹500,000 (~$6,284)/MW per project as an earnest money deposit. The successful bidder should furnish an amount equivalent to ₹1 million (~$12,569)/MW per project as a performance bank guarantee within seven days of the power purchase agreement (PPA).

TPDDL will enter into a PPA with the successful bidders for 25 years from the scheduled commissioning date or from the date of full commissioning of the projects, whichever is earlier.


The minimum bid capacity should be 50 MW, with at least 50 MW of project capacity being proposed at each site. The maximum bid capacity should be 255 MW with a greenshoe option of an additional 255 MW. The rated power capacity of one resource (wind or solar) should be at least 33% of the total contracted power capacity.

TPDDL requires 85 MW solar and 170 MW wind power out of a total 255 MW project capacity with a greenshoe option of an additional 255 MW project capacity on similar lines. Accordingly, the bidder should quote in the ratio of 1:2 (solar: wind).

Projects under construction, projects that are not yet commissioned, and those already commissioned but do not have any long-term PPA with any agency and selling power on a short-term or merchant plant basis will also be considered under this tender.

TPDDL has proposed to promote only commercially established and operational technologies to minimize the technology risk and achieve timely project commissioning.

Only type-certified wind turbine models listed in the Revised List of Models and Manufacturers issued by the Ministry of New and Renewable Energy (MNRE) will be allowed to be deployed

The cells and modules to be used should be sourced only from the models and manufacturers included in the Approved List of Models and Manufacturers.

The net worth of bidders should be at least 20% of the estimated project cost as of the last date of the previous financial year.

Bidders should have a minimum annual turnover of ₹7.5 million (~$94,270)/MW of the quoted capacity during the last financial year. They should have an internal resource generation capability in the form of profit before depreciation, interest, and taxes (PBDIT) for a minimum amount of ₹1.5 million (~$18,854)/MW of the quoted capacity during the last financial year.

They should have an in-principle approval from lending institutions committing a line of credit for a minimum of ₹1.875 million (~$23,567)/MW of the quoted capacity toward meeting the working capital requirement.

The project should be designed to deliver energy at the delivery point. The responsibility of getting the grid connectivity with long-term open access from the central transmission utility or state transmission utility will be the project developer’s responsibility.

The developer will be responsible for all transmission charges and losses and any other charges as applicable under the respective regulations until the delivery point.

The declared annual capacity utilization factor should not be less than 30%.

Recently, TPDDL announced that it became a 100% RPO (renewable purchase obligation) compliant DISCOM for the second consecutive year. The power utility company supplies electricity to over 7 million people in North Delhi. It sourced 2,200 million units of green energy from renewable sources like solar, wind, hydro, and waste to energy, including large hydro sources, and fulfilled the RPO for FY 2021-22 through physical power.

Earlier, TPDDL invited bids to procure up to 300 MW of round-the-clock renewable power (non-solar) under a short-term arrangement from August 16, 2022, to October 31, 2022, and April 1, 2023, to June 30, 2023, to meet its RPO targets.
