The Solar Energy Corporation of India (SECI) has released the list of empaneled engineering, procurement, and construction (EPC) contractors for 50 MW of grid-connected rooftop solar systems on government buildings across various states under the renewable energy service company (RESCO) model.

SECI allotted 16.48 MW out of the total capacity of 50 MW.

For the states under Zone I, GRE Electronics won a capacity of 2.5 MW, Shimato Enterprises won 1 MW, and HFM Solar won 2 MW. The L1 tariff for Zone I quoted by all three bidders was ₹5.04 (~$0.061)/kWh.

Under Zone III, both Oriana Power and Subhash Infraengineers won 3 MW, each quoting a tariff of ₹4.42 (~$0.054)/kWh.

Under Zone IV, Oriana Power won 2.98 MW. Alien Energy and Subhash Infrengineers won 1 MW each. The L1 tariff quoted by all three bidders was ₹5.25 (~$0.064)/kWh.

The state-wise allocated capacity and the L1 tariffs for the three zones are given below:

The tender was floated in September last year.

For projects located in Zones I and III, the scheduled commissioning date will be nine months from the effective date of the PPA. For projects located in Zone IV, the commission date will be 12 months from the effective date of the PPA.

The capacities under Zone II are still to be allocated.

SECI has stated that the solar modules to be used for the project must be procured from the Approved List of Models and Manufacturers (ALMM) as issued by the Ministry of New and Renewable Energy.

In March this year, SECI invited bids to empanel vendors for developing up to 5 MW of rooftop and ground-mounted solar power projects. The projects will be developed under two categories– i) for the residential sector on behalf of state implementing agencies and ii) for government organizations under capital expenditure and RESCO modes.

In April 2023, SECI disbursed ₹40.9 million (~$495,480) as subsidies under the rooftop solar program, a 194% increase from ₹13.9 (~$168,023) in the previous month.

According to Mercom’s India Solar Tender Tracker, SECI has so far floated a tender for 1.3 GW of rooftop solar projects.
