Winners in the Rajasthan Electronics and Instruments’ 50 MW Rooftop Solar Tender

The Rajasthan Electronics and Instruments Limited (REIL) has released a list of the lowest bidders (L1) for its tender to develop 50 MW of rooftop solar projects across the country.

REIL received bids from five bidders for the entire tendered capacity of rooftop solar projects. Ashlyn (Parent company: Green Affiliates) Solar Infra Private Limited, Broil Solar Energy Limited, DD Project Services Private Limited, Suryam International Private Limited, and Synergy Engineers Group Private Limited placed bids ranging from ₹3.64 (~$0.048)/kWh to ₹5.08 (~$0.067)/kWh.

The lowest tariff was quoted by DD Project Services Private Limited to set up about 2.4 MW of projects in the state of Tamil Nadu. Meanwhile, the highest tariff was quoted by Broil Solar Energy Limited for setting up 662 kW of projects in Arunachal Pradesh.

In October 2019, REIL had invited bids to develop 50 MW of grid-connected and small-scale solar projects in various states and union territories under the Renewable Energy Service Company (RESCO) model.


The projects are to be developed on the rooftops of government buildings. Solar power generated from these projects may be utilized for captive consumption, and surplus power is expected to be fed to the grid. Bidders are expected to quote a levelized tariff for 25 years. The scope of work included the design, engineering, manufacture, supply, storage, civil work, erection, testing, and commissioning of the projects.

According to Mercom’s Q1 2020 India Market Update, cumulative rooftop solar installations stand at 4.6 GW. Under the rooftop solar category, the commercial and industrial (C&I) sector has been hit the most due to low power demand because of the COVID-19 pandemic.

In March, REIL invited bids for setting up 3.5 MW of solar-projects ranging between 500 kW and 2 MW or more, at various locations and substations of the Maharashtra State Electricity Distribution Company Limited (MSEDCL). The scope of work included the design, engineering, supply, construction, erection, testing, transportation, unloading, installation, and commissioning of the projects.
