The Solar Energy Corporation of India Limited (SECI) has invited bids for the development of a 70 MW (AC) Interstate Transmission System (ISTS)-connected Solar PV Power Project integrated with a 25 MW/50 MWh Battery Energy Storage System (BESS) at Ramagiri in Sri Sathya Sai District, Andhra Pradesh, further advancing India’s efforts to strengthen renewable energy infrastructure with dispatchable clean power.
Issued under Tender No. SECI/C&P/OP/11/0002/26-27 on 24 June 2026, the tender seeks an engineering, procurement and construction (EPC) contractor to execute the project on a turnkey basis. The procurement will follow a single-stage, two-envelope bidding process, followed by an e-Reverse Auction, under the Domestic Competitive Bidding route.
The project is Package-1 of SECI’s larger 50 MW Firm and Dispatchable Renewable Energy (FDRE) initiative, which is being developed at Ramagiri and Muthukavuntla in Andhra Pradesh. The overall FDRE project has been divided into two packages, with Package-1 comprising a 70 MW (AC)/91 MW (DC) Solar PV Power Project integrated with a 25 MW/50 MWh Battery Energy Storage System, while Package-2 will consist of a 45.6 MW wind power project. Together, the projects are intended to supply reliable renewable energy under an already executed Power Purchase Agreement (PPA).
Under the scope of work, the successful bidder will undertake the complete design and engineering, procurement and supply of equipment and materials—excluding solar PV modules—along with testing at manufacturers’ works, inspections, transportation, unloading, storage, associated civil works, installation, insurance, erection, testing, commissioning and performance demonstration of the project. The contract also includes five years of comprehensive operation and maintenance (O&M) from the date of commissioning.
SECI said the project is aimed at supporting the deployment of advanced renewable energy technologies while improving grid reliability through the integration of battery energy storage with utility-scale solar generation. The initiative is expected to contribute to India’s transition towards a cleaner and more resilient power system while enabling greater utilisation of renewable energy resources.
The tender document specifies a Tender Processing Fee of Rs 25,000 plus applicable GST, while bidders will be required to submit an Earnest Money Deposit (EMD) of Rs 38,124,000. The bidding documents are available free of cost through SECI’s authorised e-tendering platform.
According to the tender, the schedule for the pre-bid meeting, bid submission and bid opening will be notified separately on the ISN-ETS e-tendering portal. Prospective bidders have also been advised to visit the project site before the pre-bid meeting to familiarise themselves with site conditions, project layout and power evacuation infrastructure.
The tender incorporates the Government of India’s Public Procurement (Preference to Make in India) policy, under which solar modules for the project will be sourced from Class-I local suppliers. It also includes provisions related to cybersecurity, integrity compliance, procurement restrictions concerning certain countries and other statutory requirements applicable to central government renewable energy projects.
Established under the Ministry of New and Renewable Energy, SECI is the country’s dedicated public sector enterprise for solar energy development and has played a leading role in implementing large-scale renewable energy projects across India. The Ramagiri Solar PV and Battery Energy Storage System project marks another significant step in expanding India’s renewable energy capacity while supporting the development of firm, dispatchable, and grid-integrated clean power infrastructure.
