SECI Partners Andhra Government for 1200 MWh BESS and Hybrid Solar Project

Solar Energy Corporation of India Limited (SECI), has formalised a partnership with the Government of Andhra Pradesh to develop a 1200 MWh Battery Energy Storage System (BESS) at Nandyal and a 50 MW Hybrid Solar Project

This collaboration is marked by the exchange of Government Orders (GOs). The announcement was made during the Energy Session of the Andhra Pradesh Partnership Summit 2025 in Visakhapatnam.

Project Approval and Mandate

The Ministry of Power designated SECI as the implementing agency for the BESS project under Market-Based Operations through a January 2025 order. 

Subsequently, the projects received approval from SECI Board Chairman Santosh Kumar Sarangi in October 2025. The Ministry of New and Renewable Energy has closely monitored the progress of both projects to ensure development milestones are met.

Development Under CAPEX Mode

Both the battery and solar projects will be developed under the CAPEX mode, with SECI assuming full investment responsibility. The formal handover of the Government Orders was led by Andhra Pradesh Energy Minister Gottipati Ravi Kumar, in the presence of senior state officials and SECI representatives. 

The 1200 MWh BESS project is among the largest grid-scale battery storage systems in India. BESS helps integrate intermittent solar and wind energy more effectively. 

Battery Integrated Renewable Power in India

India’s renewable energy capacity has increased more than fivefold in the past decade, increasing from under 35 GW in 2014 to roughly 200 GW today, excluding large hydroelectric projects. To sustain this new source of power, BESS is proving to be a crucial component. 

Even MNRE noted that while the earlier phase of renewable expansion centred on capacity addition, the current stage prioritises grid integration, energy storage, hybridisation, and market reforms, calling them the “true foundations” for a resilient renewable ecosystem. An INR 2.4 lakh crore transmission plan for 500 GW capacity is at the heart of India’s grid modernisation efforts.
