Delhi Development Authority Invites Bids For Solar-Powered Submersible System At Yamuna Vatika Park

The Delhi Development Authority (DDA), through its Executive Engineer (E), Electrical Division No. 13, has issued an online e-tender inviting bids from specialized agencies for the modernization and upgradation of existing parks and green belts. The specific focus of the project is the Supply, Installation, Testing, and Commissioning (SITC) of a solar-powered submersible system at Yamuna Vatika Park. The estimated cost of the project is ₹15,64,638, and the initiative aims to promote clean and sustainable energy use in public spaces.

The tender defines similar work for eligibility as “SITC of Solar plant,” making it clear that only agencies with prior experience in solar installations are eligible to participate. The technical requirements for the project ensure that high-quality materials and long-lasting systems are used. The Solar PV Module must carry a 25-year warranty, guaranteeing that its peak watt capacity remains at least 90% after 10 years and 80% after 25 years. Other equipment used in the system must have a minimum warranty of 12 months from the date of acceptance and handover.

The contractor will be given two months to complete the entire project from the date of commencement. This timeline reflects DDA’s intent to implement solar energy-based infrastructure in its parks efficiently and within a short duration. The last date for submitting the online bids is 3:00 PM on October 24, 2025, and the bids will be opened the following day at 3:30 PM on October 25, 2025. Bidders are required to keep their offers valid for 75 days from the date of opening the technical bid, ensuring adequate time for evaluation and finalization.

An Earnest Money Deposit (EMD) of ₹31,293 is mandatory for all participants. The amount must be deposited via RTGS or NEFT in favor of the Sr. Account Officer, CAU (Horticulture), DDA. After the bid evaluation, the successful contractor will need to submit a Performance Bank Guarantee (PBG). The percentage of the PBG depends on how the bid price compares with the estimated cost. For bids up to 25% below or above the estimate, a 5% PBG is required. If the bid is between 25% and 40% below, an additional 0.34% per percent decrease applies, capped at 10%. For bids more than 40% below the estimate, a flat 10% PBG is mandatory. Failure to submit this guarantee will lead to automatic forfeiture of the EMD.

This project marks another step in DDA’s commitment to integrating renewable energy systems into its urban development plans, promoting sustainability and environmental responsibility.
