Multi Infrastructure & Engineering (MIEPL) has won the Solar Energy Corporation of India’s (SECI) auction to set up a cumulative 4.125 MW solar power project at IIT Kharagpur, West Bengal.

The tender was floated in December 2024. MIEPL must complete the project in 270 days.

The project’s cumulative capacity includes 2,900 kW rooftop, 1,000 kW ground-mounted, and 225 kW elevated structure systems.

MIEPL must use modules from the Approved List of Models and Manufacturers.

The company will set up grid-connected rooftop solar systems consisting of solar arrays, module mounting structures, power conditioning units with maximum power point trackers, inverters, controls, protections, interconnect cables, junction boxes, distribution boxes, and switches.

It will install the solar systems without a battery. MIEPL will also provide operation and maintenance for 25 years.

Solar modules used in grid-connected solar systems must have a minimum peak output wattage of 90% at the end of 10 years and 80% at the end of 25 years.

Each solar module must use a radio-frequency identification tag. In case of an energy supply shortfall, MIEPL will be levied liquidated damages at 50% of the tariff.

SECI had also mandated using commercially established and operational technologies to minimize technology risks and achieve timely project commissioning.

Recently, SECI issued a request for selection to develop grid-connected rooftop solar projects with a cumulative capacity of 6.25 MW. These projects will be implemented on a build-own-operate basis.

SECI also invited bids for the engineering, procurement, and construction of 4.55 MW of grid-connected rooftop solar projects at multiple educational institutions across Bihar, Chhattisgarh, Sikkim, Assam, and Manipur.

In March this year, the Central Electricity Regulatory Commission approved SECI’s petition to adopt a tariff for 1,200 MW interstate transmission system connected solar projects with 600 MW/1,200 MWh energy storage systems. The approved tariff ranges between ₹3.41(~$0.039)/kWh and ₹3.42(~$0.04)/kWh.
