Smart Roof Solar Solutions and Gourav EnerGen India have won Power Grid Corporation of India’s (POWERGRID) auction to implement 3 MW of rooftop solar systems on its buildings in India’s western regions under the PM Surya Ghar: Muft Bijli Yojana.

Both companies won 1 MW at a contract value of ₹36.8 million (~$436,638) each. The remaining 1 MW capacity will be divided among other qualified bidders, including Suncraft Energy, Sunshell Power, and Rajasthan Electronics and Instruments.

The tender was floated in February 2025 for the supply and installation of 7 MW of rooftop solar systems in the country’s northern and western regions. The western regions, including Gujarat, Madhya Pradesh, Dadra and Nagar Haveli, Daman and Diu, Maharashtra, Goa, and Chhattisgarh were assigned 3 MW.

The successful bidders will supply, install, and commission the solar systems. They will also provide a three-phase net meter, reverse power flow scheme, or zero export controller.

If a reverse power blocking scheme or zero export controller is required instead of a net meter, it must be included at no additional cost.

The systems must be installed within six months of issuing the work order. The companies will also undertake comprehensive system maintenance for five years from the commissioning date or the start of net metering, whichever is later.

Under the PM Surya Ghar program, the Ministry of New and Renewable Energy plans to install rooftop solar systems on all central and state government buildings by December 2025. With an outlay of ₹750 billion (~$9.04 billion), the program aims to increase residential rooftop solar capacity and empower households to generate electricity until 2026-27.

Recently, POWERGRID received letters of intent for three transmission projects from REC Power Development and Consultancy under tariff-based competitive bidding, cumulatively worth ₹107.5 billion (~$1.2 billion).

In January this year, POWERGRID invited bids for a 1.07 MW rooftop solar project at the National Institute of Technology Durgapur in West Bengal. This project is a part of POWERGRID’s corporate social responsibility initiatives.

In the same month, POWERGRID won two projects from REC Power Development and Consultancy to establish an interstate transmission system and augment substation capacity in Gujarat and Karnataka.
