Central Mine Planning & Design Institute (CMPDI), a subsidiary of Coal India, has invited bids for the design, supply, installation, commissioning, and testing of grid-connected solar power projects with a cumulative capacity of 13 MW.

These projects are intended for Central Coalfields Ranchi at NK Area Chatra, Jharkhand, and come with a five-year operation and maintenance (O&M) period.

The last date for the submission of bids is March 28, 2024. Bids will be opened the same day.

Work should commence within 30 days of the issuance of the letter of acceptance and the submission of the performance security.

Alternatively, the work should begin within seven days after the site is handed over for the first activity.

Bidders have to pay ₹5 million (~$60,391) as an earnest money deposit.

The total contract period spans 2,065 days and consists of two main phases:

• Construction of the plant, including testing and commissioning, is allocated 240 days.
• The comprehensive operation and maintenance of the plant will be for 1,825 days.

Bidders must have completed similar works, specifically related to the design, supply, installation, commissioning, and testing of grid-connected ground-mounted, rooftop, or floating solar projects.

They must have completed three similar completed works, each with a cost not less than 20% of the estimated cost put to tender, or two similar completed works, each with a cost not less than 25% of the estimated cost put to tender or, one similar completed work, with a cost not less than 40% of the estimated cost put to tender.

The average annual financial turnover during the last three years, ending March 31, 2023, should be at least 30% of the estimated cost put to tender.

Bidders must provide a certificate confirming the possession of sufficient working capital, which should be at least 20% of the annualized value or estimated value, whichever is less of the specified work.

This working capital should include access to lines of credit and the availability of other financial resources necessary to meet the project requirements.

In August last year, CMPDI invited bids to implement a grid-connected 8.5 MW solar project for Central Coalfields.

CMPDI also invited bids to install 1.03 MW solar projects for Central Coalfields.
