NTPC has invited tenders for the engineering, procurement, and construction (EPC) of a 250 MW ground-mounted solar power project in Bikaner, Rajasthan.

Bids must be submitted on June 30, 2025. Bids will be opened on the same day.

Bidders must pay a bid document fee of ₹22,500 (~$263.49).

The scope of work entails the design, engineering, manufacturing, installation, testing, and commissioning of the solar project.

The successful bidders must provide operation and maintenance services for three years.

It also includes completing a pre-engineered-type inverter room (if required) with low and high-tension (HT) switchgear associated with the power conditioning unit. For string inverters, a pre-engineered HT switchgear room must be constructed.

Selected bidders must conduct grading and vegetation clearance, topographical surveys, and geotechnical investigations at the project site. They must arrange power and water supply for the project’s construction.

They must also complete the associated civil work for interfacing with the grid, including providing transformers, panels, protection systems, cables, metering at the 33 kV level, and facilitating the grid compliance study.

Power evacuated must be up to the 33 kV main pooling switchgear at the project owner’s pooling substation. Selected bidders must lay and terminate HT cables from the block boundary to the owner’s main 33 kV pooling switchgear.

The scope of work includes the provision of spare equipment and module cleaning systems, and installing them.

Selected bidders must also construct internal roads, pathways, and drainage systems per the project site’s general layout and topography. They must provide a supervisory control and data acquisition system for remote monitoring and control of inverters. The system must include all the hardware and software, along with a complete weather monitoring station that can also detect cloud cover.

Successful bidders must install dynamic reactive power compensation equipment and harmonic filters. They must also provide CCTV cameras along with remote monitoring systems, covering 100% of the project’s periphery, entry/exit gates of the solar blocks, and the weather monitoring station.

Successful bidders must design and construct the foundation for erecting tracker-based module mounting structures for the solar panels. This scope includes fixing the mounting structures and interconnecting the solar module.

String/central inverters with a minimum cumulative capacity of 250 MW, equipped with maximum power point tracking technology, along with associated cables, cabling, transformers, and switchgear, must be supplied.

The project must be completed within 15 months.

Bidders must be Class-I local suppliers.

Bidders must have designed, supplied, erected/supervised erection, and commissioned/supervised commissioning of solar projects with a minimum cumulative capacity of 40 MW. This capacity must include at least one project with a minimum capacity of 10 MW. This project must have been operational for at least six months before the bid opening date.

Alternatively, bidders must be solar project developers with a minimum cumulative installed capacity of 40 MW. This capacity must include at least one project with a minimum 10 MW capacity. This project must have been operational for at least six months before the bid opening date.

Bidders must have executed an industrial project either as a developer or an EPC contractor in the power/steel/oil and gas/petrochemical/ fertilizer/cement/coal mining/ including coal handling and/or any other process industry in a single project or work in the last ten years. The project/work’s value must have been at least ₹1.59 billion (~$18.61 million). Industrial non-renewable energy projects must have been operational for at least one year before the bid opening date. Renewable energy projects must have been operational for at least six months.

Bidders must have executed at least one electrical substation of a minimum 33 kV voltage level as a developer or EPC contractor. The substation must have comprised a minimum 33 kV level circuit.  Substations in non-renewable energy projects must have been operational for at least one year before the bid opening date. Those in renewable energy projects must have been operational for at least six months.

Bidders must have a minimum average annual turnover of ₹1.59 billion (~$18.61 million) during the last three financial years. If a bidder cannot satisfy the annual turnover criteria on its own, its holding company must meet the requirement, provided its net worth as of the last day of the preceding financial year is at least equal to its paid-up share capital.

Bidders must have a minimum net worth of 100% of their paid-up share capital on the last day of the preceding financial year. If a bidder cannot satisfy this requirement on their own, they can meet it based on the strength of their subsidiaries and/or holding company and/or subsidiaries of their holding companies. Bidders, their subsidiaries, holding company, or the holding company’s subsidiaries combined must have a net worth of at least 100% of their total paid up share capital. Individually, their net worth must be at least 75% of their respective paid-up share capital.

Recently, NTPC Renewable Energy invited bids for the engineering, procurement, and construction of a 245 MW solar power project at the Khavda Renewable Energy Park in the Rann of Kutch, Gujarat.
