Vikran Engineering, Sterling and Wilson Renewable Energy, Bondada Engineering, and Kintech Synergy have won orders from NTPC Renewable Energy (NTPC REL) for the balance of system (BoS) works for 1.4 GW of grid-connected solar power projects in Chitrakoot (2 x 400 MW) and Lalitpur (2 x 300 MW) in Uttar Pradesh.

Vikran won the order for the 400 MW solar project in Chitrakoot-1, valued at ₹4.59 billion (~$51.08 million). Sterling and Wilson won the order for 400 MW solar projects in Chitrakoot-2.

Bondada won the order for 300 MW of solar projects in Lalitpur-1, valued at ₹3.91 billion (~$43.52 million). Kintech Synergy won the order for 300 MW solar projects in Lalitpur-2.

The tender was floated in December last year.

The projects are located at the Lalitpur and Chitrakoot Solar Parks developed by TUSCO.

Selected bidders must design, engineer, manufacture, install, test, and commission the solar photovoltaic project. NTPC REL will supply the solar modules as free-issue items.

Successful bidders must also install, test, and commission the supplied solar modules. They must grade and clear vegetation at the project site and conduct topographical surveys and geotechnical investigations.

They must design and construct the foundations and erect the fixed-tilt module mounting structures for the solar modules at a 1.45 DC: AC ratio. This responsibility includes installing and interconnecting the modules.

Selected bidders must also arrange the power and water supplies for construction purposes.

India added a solar capacity of 26.6 GW in the first nine months (9M) of the calendar year (CY) 2025, an increase of 53.7% year-over-year (YoY) from 17.3 GW, according to the Q3 2025 India Solar Market Update Report by Mercom India Research. Large-scale solar accounted for 81.5% of the capacity commissioned in 9M 2025, while rooftop solar contributed 18.5%.
