SECI and Andhra Pradesh Finalise 1200 MWh Battery Energy Storage System

Solar Energy Corporation of India Limited (SECI), a Navratna public sector company under India’s Ministry of New & Renewable Energy (MNRE), exchanged Government Orders (GOs) with the Andhra Pradesh Government for the development of a 1200 MWh Battery Energy Storage System (BESS) at Nandyal and a 50 MW Hybrid Solar Project.

The exchange took place during the Energy Session of the Andhra Pradesh Partnership Summit 2025 held in Visakhapatnam, organised by the Department for Promotion of Industry and Internal Trade, Government of Andhra Pradesh, in association with the industry body, CII.

In January 2025, India’s Ministry of Power had designated SECI as the implementing agency for the 1200 MWh BESS project under Market-Based Operations. The SECI Board Chairman subsequently approved the project in October.

Both the BESS and Hybrid Solar projects will be developed under the CAPEX Mode, with SECI assuming full investment responsibility. 

Battery storage technology is essential to address the intermittency of renewables by storing excess energy for use during periods of low generation or high demand. These energy storage solutions enable industrial and utility customers to maintain a steady power supply. 

The exchange of GOs marks a significant milestone in strengthening Andhra Pradesh’s renewable energy infrastructure. SECI reaffirmed its commitment to partnering with States and Central Ministries to accelerate India’s transition towards a greener, more resilient energy future.

In Andhra Pradesh, another major GW-scale integrated renewable energy project, comprising 4000 MW of solar, 1000 MW of wind, and 1680 MW of pumped hydropower generation, is also under construction. 

The Ministry of New and Renewable Energy has been closely monitoring the progress and development of these projects.

Once these projects are developed, they will signal a significant leap in clean energy storage capacity, strengthening the state’s renewable ecosystem and powering India’s transition to a more resilient, storage-enabled green grid.
