Damodar Valley Corporation (DVC) has invited bids from engineering, procurement, and construction (EPC) contractors to commission an 8 MW ground-mounted solar power project with associated systems, including the power evacuation system in Dhanbad, Jharkhand.

Contractors must also provide five years of comprehensive operation and maintenance services.

The last day to submit the bids is March 27, 2023. Bids will be opened the next day.

Bidders must furnish an earnest money deposit of ₹5.2 million (~$62,437).

Selected bidders must submit a performance security between 5% to 10% of the contract value. However, if the contract value is ₹100,000 (~$1,210) or less, they need not submit the performance security.

In addition to the performance security, retention money equivalent to 5% of each running bill will be withheld until final acceptance to ensure the completion of the project.

Contactors must supply solar modules, mounting structures, string combiner boxes, power conditioning units, inverters, and all the necessary equipment required to construct a 33 kV bay at the existing 132/33 kV Panchet Hydel Station switchyard.

Contactors must ensure that vendors will provide a guarantee for the materials and equipment for 18 months from the date of delivery or 12 months from the date of commissioning, whichever is earlier.

The modules must be warranted with a linear degradation rate of power output except for the first year and guarantee a minimum of 80% of the initial rated power output at the end of 25 years from the date of successful commercial operation.

DVC has stated that the mono-crystalline or poly-crystalline modules used for the project must be from the Approved List of Models and Manufacturers (ALMM) issued by the Ministry of New and Renewable Energy.

The declared capacity utilization factor must not be less than 22.5% per annum.

Earlier, DVC had invited bids to install and commission 10 MW of grid-connected solar power projects at its thermal powers station in Koderma, Jharkhand.

Last January, DVC invited bids from EPC contractors to set up a 12 MW grid-connected ground-mounted solar power project with associated systems, including the power evacuation system at the Koderma Thermal Power Station in Jharkhand.

According to Mercom’s India Solar Tender Tracker, DVC has issued tenders for 72 MW of solar power projects so far.
