The Gujarat State Electricity Corporation Limited (GSECL) has invited bids for the supply and replacement of degraded polycrystalline solar modules installed at the 1 MW ash dyke solar project in Gandhinagar.

The scope of work includes replacing all technologies of existing modules, except monocrystalline modules, with the same capacity of high-efficiency polycrystalline modules. The new modules have to be integrated into the existing structure. The required polycrystalline module size and capacity should be identical and retrofitted.

The estimated cost of the turnkey project is ₹25.28 million (~$344,288). The successful bidder will have to furnish 10% of the order cost as the performance bank guarantee.

The last date to submit the bids online is May 21, 2021.

Micro, small, and medium enterprises will have to submit an amount of ₹80,000 (~$1,089) as the earnest money deposit, while the sum to be deposited by other units is ₹120,000 (~$1,634).

To participate in the bidding process, the bidder should have experience in supplying and installing a solar project of a minimum capacity of 1 MW. The bidder should also submit the solvency certificate of 20% of the estimated cost from any notified bank.

To qualify for the project, interested parties will have to submit the order copies of similar work executed for the government or public sector undertakings.

The technical specifications and quantity of the solar modules are given below:

As per the tender document, the bidder will have to give a guarantee for five years for module manufacturing defects and a performance warranty for 25 years. The degradation for the first ten years should not be more than 10%, while the damage for the next 15 years should not exceed 20%.

The supply of the materials should be completed within four months from the date of the drawing approval, and the work should be completed within two months after the receipt of materials at the site.

The tender notice further mentions that If GSECL, at any point, is not satisfied with the progress of the work or feels the manpower is inadequate, it could deploy other agencies to speed up the task. Any amount spent to that end will be billed to the contractor.

Last month, GSECL invited bids for the design, engineering, supply, procurement, and construction of 112 MW grid-connected solar projects ranging from 10 MW to 50 MW at substations of the Gujarat Energy Transmission Corporation.
