NVVNL

NTPC Vidyut Vyapar Nigam Limited (NVVNL), a subsidiary of NTPC, has issued a tender for the development of a 25.651 MW grid-connected rooftop solar power project. This project is to be implemented on the rooftops of buildings owned by the Delhi Police and other government entities in nearby districts. The deadline for bid submission is set for September 9th.

According to the tender, the Solar Photovoltaic (PV) installations will be placed on the rooftops of various buildings, including those of the Delhi Police, NTPC EOC, NTPC Township in Noida, and other government buildings in Delhi and surrounding districts. These installations are to be located in shadow-free areas to optimize solar power generation. While the project’s tentative capacity is 25.651 MW, the final capacity will be determined by detailed engineering and approved rooftop designs.

NVVN outlined that the successful bidder will be responsible for various aspects of the project, including design, engineering, testing, and other related activities. During the design and installation phases, tasks will include visual roof assessments, arranging water and electricity, ensuring security, and determining the optimal solar capacity for each site. If a rooftop lacks access, a permanent MS staircase or ladder must be installed.

The tender also mandates site inspections, advising bidders to assess the site and its surroundings before submitting their bids. This will allow bidders to understand the nature of the roofs, the materials required, site access, and other contingencies.

For project execution, the selected bidder will handle the design, engineering, supply, installation, testing, and commissioning of the solar systems according to standard specifications. This includes connecting the system to the existing mains, ACDB, and interfacing with internal electrical loads. Necessary approvals for grid interfacing must be obtained from the relevant authorities.

The project’s commissioning will be validated by continuous power generation for five hours using instruments and meters, including net metering or net billing. The bidder is responsible for commissioning the project and will also provide 10 years of comprehensive operation and maintenance (O&M) services, covering all necessary materials, manpower, and safety equipment.
