Bharat Coking Coal Limited, a subsidiary of Coal India Limited, has issued a turnkey tender for the development of a large solar power project in Dhanbad. This project reflects the growing shift of traditional coal-based companies toward renewable energy and sustainable operations.
The proposed project involves setting up a grid-connected solar power plant with a capacity of 25 MW (AC) and 35 MWp (DC). It will be developed at the Dugdha-II site of the Dugdha Coal Washery. The scope of work is comprehensive and includes design, engineering, procurement, supply, construction, erection, testing, and commissioning of the plant. In addition to this, the selected bidder will also be responsible for operating and maintaining the project for a period of ten years.
The tender process is being managed by Central Mine Planning & Design Institute Limited on behalf of BCCL. The estimated cost of the project, including GST, is around ₹155.23 crore. This investment highlights the company’s commitment to integrating clean energy solutions into its operations and reducing dependence on conventional energy sources.
The total contract duration is 4,017 days. This includes 365 days allocated for construction, commissioning, and performance guarantee testing. After this phase, the project will enter a long-term operation and maintenance period of 3,652 days, which is equal to ten years. Work on the project is expected to begin within 30 days from the issuance of the Letter of Acceptance or within seven days after the site is handed over, depending on which happens later.
To participate in the tender, bidders must meet specific technical and financial requirements. Companies must have prior experience in executing similar solar photovoltaic projects, including ground-mounted, rooftop, or floating solar installations, within the last ten years. On the financial side, bidders must show an average annual turnover of at least 30% of the estimated project cost over the past three financial years. They are also required to have a minimum net worth of 10% of the project cost.
As part of the bidding process, an Earnest Money Deposit of ₹50 lakh is required. This amount must be paid through online modes such as net banking, NEFT, or RTGS. The successful bidder will also need to submit a Performance Bank Guarantee within 21 days of contract acceptance to ensure proper execution of the project.
The tender was officially published on March 30, 2026, and all bids must remain valid for 180 days from the final submission date. The bidding process will follow a two-cover system, where technical and financial bids are submitted separately.
Overall, this project is expected to support BCCL’s long-term sustainability goals and contribute to India’s transition toward cleaner energy sources.
