Tata Power to Procure 300 MW of Non-Solar Renewable Power Under Short-Term Open Access

Listen to this article

Tata Power Delhi Distribution (Tata Power-DDL) has invited bids for procurement of up to 300 MW of round-the-clock (RTC) renewable power (non-solar) under a short-term arrangement for the period from August 16, 2022, to October 31, 2022, and April 1, 2023, to June 30, 2023, for meeting its renewable purchase obligation (RPO) targets.

The last date to submit the bids is August 2, 2022. Bids will be opened on the same day.

Bidders should submit an amount equivalent to ₹30,000 (~$376)/MW per month on an RTC basis as an earnest money deposit.

The successful bidder should furnish a contract performance guarantee within seven days from the selection date of successful bidders for an amount equivalent to ₹200,000 (~$2,506)/MW per month of the contract period.


The successful bidders would be required to apply for short-term open access on behalf of Tata Power-DDL so that separate short-term open access charges up to the delivery point are not to be billed to Tata Power-DDL nor payable by the bidder.

Tata Power-DDL reserves the right to increase the supply quantum by 20% if there is a shortfall in the total quantity of power to be procured or if the same is required otherwise.

The power supply may be offered from one or more sources subject to the condition that offers from each source should not be less than 1 MW (minimum bid capacity).

The quantity of power offered by the bidder should be firm power for the dates mentioned in the table above.

If the bidder is a trader, they should submit a copy of executed power purchase agreement (PPA) with the generator or an equivalent arrangement for supply of power and a copy letter of authorization from the generator.

The successful bidder should apply for booking the open access transmission corridor on behalf of Tata Power-DDL to the regional load despatch center (RLDC) in line with applicable short-term open access regulations.

The successful bidder should be fully responsible for filing the open-access application before the nodal RLDC and coordinating with the relevant RLDC or state load despatch center (SLDC) to get the timely booking of the open access corridor.

The distribution company (DISCOM) has further stated that the certificate confirming the renewable status of the power from the appropriate authority should be furnished by the supplier monthly along with bills.

A rebate of 2% will be applicable on payment of the energy bill within the due date of payment. No rebate will be applicable on payment of open access bills.

A surcharge of 1.25% per month will be applied on all payments outstanding for more than 30 days beyond the due date.

Both parties should ensure that actual scheduling does not deviate by more than 15% of the contracted power monthly.

If the deviation from the procurer side is more than 15% of contracted energy for which open access has been allocated every month, the procurer will pay compensation to the successful bidder at 20% of tariff per kWh for the shortfall over the permitted deviation of 15% while continuing to pay open access charges as per the contract.

The same holds true for the successful bidder.

Tata Power-DDL will provide a revolving Letter of Credit equivalent to 100% of the weekly energy corresponding to the contracted capacity at the tariff indicated in the Letter of Award.

In 2020, Tata Power-DDL issued a request for proposal for procuring up to 150 MW of renewable (non-solar) power on a short-term basis for meeting its RPO targets.
