The Solar Energy Corporation of India (SECI) has invited bids from Solar Power Developers (SPDs) for the development of 5.29 MW (5,290 kW) of grid-connected rooftop solar photovoltaic (RTSPV) projects under the RESCO (Renewable Energy Service Company) mode through tariff-based competitive bidding. The initiative forms part of RTSPV Tranche-XII and aims to expand rooftop solar deployment across multiple client organisations.
Under the tender, the selected developers will be responsible for the complete design, engineering, procurement, supply, installation, testing, commissioning, and operation and maintenance (O&M) of the rooftop solar projects throughout the term of the Power Purchase Agreement (PPA). The scope also includes obtaining grid connectivity approvals, net-metering permissions, insurance, and all statutory clearances required for project execution.
The projects will be implemented under the RESCO model, wherein developers will invest in, own, operate, and maintain the rooftop solar plants while supplying electricity to the respective client organisations. The rooftop solar systems will primarily utilise photovoltaic technology, with the tender remaining technology-agnostic for eligible solar PV solutions.
SECI stated that the estimated cumulative project capacity is around 5,290 kW, while the final capacity for each project will be confirmed during the execution of the Power Purchase Agreement following site assessments and mutual agreement between the developer and the client organisation.
According to the tender conditions, the selected developers will sign separate Power Purchase Agreements (PPAs) with the respective client organisations. Each PPA will remain valid for 25 years from the commercial operation date (COD) of the project, providing long-term revenue visibility for developers.
The tender also requires developers to submit performance guarantees and service charges before PPA execution. SECI will facilitate the PPA signing process after verifying compliance with the tender’s technical, financial, and shareholding requirements. Developers executing projects through Special Purpose Vehicles (SPVs) must maintain the prescribed controlling shareholding for at least one year after project commissioning.
The initiative is expected to support India’s rooftop solar expansion by enabling government and institutional consumers to adopt clean energy under the RESCO model while reducing upfront investment requirements. The projects will also contribute to increasing distributed renewable energy capacity and advancing the country’s clean energy transition.
