Selected bidders must identify, acquire, and transfer ownership/lease encumbrance-free land to NTPC REL. They must also identify and arrange grid-connectivity at the interconnecting substations.

Successful bidders must conduct the project site’s levelling/grading and vegetation clearance, topographical survey, and geotechnical investigations. They must also design and construct the project’s foundation and erect the solar module mounting structure.

The scope of work also involves arranging power and water supply for construction. Additionally, it includes constructing a pre-engineered type inverter room (if applicable) with a power conditioning unit associated low and high-tension switchgear.  String inverters will require a pre-engineered high-tension switchgear room.

Selected bidders must construct an extra high-voltage (EVH) switchyard, with power transformers, a control and monitoring center systems building, and protection, control, communication, automation, and other auxiliary systems. They must also provide an EVH transmission system up to the interconnecting grid substation. They must provide a terminal bay at the substation along with necessary integrations.

Successful bidders must conduct all associated EPC works for the development of the solar project, as well as the power evacuation system and telemetry up to the interconnecting grid substation. They must also conduct performance testing for guaranteed generation at the interconnection point.

Module cleaning systems, including the supply and installation of all accessories, are also part of the project’s scope.

Successful bidders must provide a supervisory control and data acquisition system for remote monitoring and control of inverters. They must also install dynamic reactive power compensation equipment and harmonic filters.

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

Alternatively, bidders must have completed solar projects of a minimum cumulative capacity of 40 MW as a developer. At least one of these projects must have had a minimum capacity of 10 MW. Such projects must have been operational for at least six months before the bid opening date.

Bidders could also have executed an industrial project in the power/steel/oil and gas/petro-chemical/ fertilizer/cement/coal mining, including coal handling/ any other process industry, as a developer or an EPC contractor in the last 10 years. The project must have cost at least ₹2.06 billion (~$23.54 million). A single project must have been operational for six months to one year before the bid opening date.

Bidders must have executed at least one electrical substation of a minimum 33 kV voltage level as a developer or an EPC contractor. The substation must have consisted of 33kV or above voltage level circuit breakers and a power transformer. The substation must have been operational for six months to one year before the bid opening date.

Alternatively, bidders must be an Indian company registered in India. They must be a group/holding/subsidiary company of a firm, meeting the previously mentioned requirements.

Bidders must have an average annual turnover of ₹2.06 billion (~$23.54 million). They must have a net worth of 100% of their paid-up share capital.
