NVVN Invites EPC Bids for 20 MW Rooftop and Ground Solar Projects

NTPC Vidyut Vyapar Nigam Ltd. (NVVN), a wholly owned subsidiary of NTPC Ltd., has invited bids for the enlistment of engineering, procurement, and construction (EPC) vendors to execute rooftop and ground-mounted solar photovoltaic (PV) projects.

The enlistment aims to create a qualified vendor pool for executing solar projects aggregating up to 20 MWp per vendor. The scope of work under the enlistment is comprehensive and includes complete turnkey execution, ranging from design, engineering, procurement, transportation, storage, and installation to testing and commissioning of the solar PV systems. Vendors will also be responsible for civil and electrical works, grid connectivity, module cleaning systems, remote monitoring setup, and post-commissioning operation and maintenance for a period of 10 years.

For rooftop solar projects, vendors must obtain net metering approvals and establish centralized data monitoring systems. Ground-mounted project responsibilities extend further to include site development, construction of control rooms and allied infrastructure, installation of SCADA systems, and deployment of mandatory spares.

Interested bidders can access the detailed enlistment documents and submit their applications via the GePNIC portal by July 23, 2025. NVVN has clarified that all official communications will be handled by its Contracts team based in Noida.

Although specific Earnest Money Deposit (EMD) and Performance Bank Guarantee (PBG) amounts will be provided in subsequent project-specific enquiries, financial eligibility conditions require bidders to meet a defined average annual turnover, denoted as ‘X’, based on project scope. Additionally, applicants must demonstrate a net worth equal to or exceeding 100 percent of their paid-up share capital as per their latest financial statements.

To qualify technically, vendors must meet at least one of several criteria: successful commissioning of 400 kWp of cumulative solar PV capacity (with at least one 40 kWp plant operating for over six months), prior execution of industrial EPC projects valued above INR 4 crore, or experience in completing electrical substations of 11 kV or higher.

The enlistment will remain valid for one year, with the possibility of extension for another year. Upon enlistment, NVVN will issue project-specific enquiries to qualified vendors, as per its procurement schedule. The utility has also reserved the right to cancel the enlistment process at its discretion.
