NTPC Vidyut Vyapar Nigam (NVVN), a wholly-owned subsidiary of NTPC, has invited bids from enlisted developers to install 6,352 kW of grid-connected rooftop solar power projects on various buildings of public sector undertakings under the Department of Defense Production in the southern region.

The last date to submit the bids is February 1, 2024. Bids will be opened on February 2.

The successful bidder will be responsible for the design, engineering, testing, assessment of roofs, water arrangements, electricity security, and determination of the optimal capacity for setting up the solar power systems.

The projects must be completed within 270 days of receiving the work order.

The scope of work includes operation and maintenance (O&M) activities for ten years.

The systems are to be installed at 13 locations across Chennai, Hyderabad, Tiruchirappalli, Bengaluru, Nimmaluru, Vishakhapatnam, Palakkad, and Aruvankadu.

Bidders must submit a bid security amount of ₹5 million (~$60,188). The selected bidder must submit a contract performance guarantee amount equivalent to 10% of the contract value within 28 days of receiving the award notification.

They must also submit an O&M performance guarantee amount equivalent to 10% of the O&M contract price.

NVVN intends to finance the project through external commercial borrowings, domestic commercial borrowings, and its own sources.

Only bidders enlisted by NVVN and Class-I and Class-II Local Suppliers are eligible to participate in the tender.

The local content requirement to categorize a bidder as a ‘Class-I local supplier’ is a minimum of 50%, and for a ‘Class-II local supplier,’ the ‘local content’ requirement is a minimum of 20%.

The average annual turnover of the enlisted bidders should not be less than ₹292.19 million (~$3.52 million) or in equivalent foreign currency during the preceding three financial years.

The net worth of the bidders as of the last day of the preceding financial year should not be less than 100% of their paid-up share capital.

Only modules listed in the Approved List of Models and Manufacturers by the Ministry of New and Renewable Energy and with a minimum 540 Wp capacity must be used for the projects.

The developer must maintain the minimum Annual Capacity Utilization Factor of 16% measured at the delivery point for the ten operational years, failing which they will be liable to pay for the shortfall in generation.

In July last year, NVVN invited bids to enlist engineering, procurement, and construction contractors to develop floating and ground-mounted solar power projects up to 10 MW.
