TATA POWER DDL Issues 200 MW FDRE Tender With ESS & Greenshoe Option

TATA Power DDL has recently issued a tender to select renewable energy (RE) power developers to supply 200 MW of Firm and dispatchable renewable Energy (FDRE) power with ESS and a greenshoe option. The project is being offered on a Build-Own-Operate (BOO) basis, which offers an additional 200 MW from ISTS-connected RE power projects in India. It has sought bids to develop the project until December 6, 2025.

For this, the bidder/developer would either set up storage capacity itself or tie up with ESS developers to meet the project parameters for ‘firmness and dispatchability’ and submit a single bid for the same as per the terms and conditions stipulated in this RfS.

Scope of Work

The TATA Power DDL tender requires bidders to supply the contracted firm and dispatchable renewable energy (RE) with ESS from ISTS-connected RE projects. These projects are based on generating systems including solar, wind, or any other renewable resource for the supply of RE power combined with ESS.

The developer is also required to create a transmission network up to the interconnection point/delivery point to supply RE power to TPDDL at their own cost as per the tender and PPA provisions.

TPDDL requires 60% of the contracted capacity in energy terms to be supplied in the summer months (April to September) and the remaining 40% in the winter months (October to March) for the entire tenure.

TATA Power also mandates the developer to build the renewable energy projects anywhere in India. For a single project, the renewable energy generation components, along with ESS installed, if any, can either be co-located or located at different locations. The tender allows bidders to choose the ISTS substations for interconnection of the project to the grid on a pan-India basis.

Power Supply

The tender also states that the peak hours under this project will be four hours (two slots of two hours each) out of 24 hours, as declared by TPDDL. The same may be notified by TPDDL separately for each month. This will be communicated to the developer 15 days before the start of the month, and the developer is required to meet the energy supply criteria for the sum of the peak hours in line with the provisions of the tender and the PPA.

To allow optimization of RE plant operations, the RPD is permitted to supply power from the RE plant in excess of the contracted capacity to any third party or power exchange without requiring a no-objection certificate from TPDDL.

The RPD may also sell power offered on a day-ahead basis to TPDDL (within the contracted capacity) but not scheduled by TPDDL, to any third party or power exchange without requiring an NOC from TPDDL.

In case such power is purchased by TPDDL, it can be purchased at the PPA tariff. However, it may be noted that at any instance of energy supply from the project, priority can be given to meeting the energy requirements as per the PPA before selling any quantum of energy in the open market.

The maximum time period allowed for the commencement of power supply for the full contracted capacity, with applicable liquidated damages, will be limited to six months from the SCSD or the extended SCSD (if applicable).
