India Launches First Fully Automated Battery Energy Storage System Factory in Karnataka

India’s first fully automated BESS factory opens in Karnataka
============================================================

Energy storage is vital for harnessing solar and wind power, as emphasized by Karnataka’s energy minister during the inauguration of India’s first fully automated battery energy storage system (BESS) factory. Lineage Power, a manufacturer specializing in power conversion systems and power plant controls, officially opened its 5GWh BESS factory in Bengaluru, Karnataka, on June 27, 2025.

At the event, Karnataka’s energy minister, KJ George, highlighted that battery storage systems would be implemented at all solar PV power plants to store excess energy for grid supply “as and when required,” according to a tweet from the state government’s Department of Information and Public Relations (DIPR). He noted that wind and solar PV now account for 65% of Karnataka’s energy generation. While the state has maintained a surplus for several years, he stated, “effective storage systems are essential to store this energy and supply it when needed,” especially during peak demand periods. Although the DIPR tweet hinted at a future mandate for storage, George did not explicitly mention any mandatory requirements during his remarks.

### Bringing India Closer to Its 500GW Goal

Lineage Power, owned by Pace Digitek—a solutions provider in telecom and energy based in Bengaluru—established the new factory in Bidadi, which is touted as a “one of its kind, fully automated 5GWh BESS manufacturing facility.” The company was acquired in 2014 from General Electric (GE), which had previously purchased it from ABB.

Indian Union Minister of New and Renewable Energy, Pralhad Joshi, also attended the inauguration. He stated that the Lineage Power factory would produce 5MWh DC blocks for utility-scale applications paired with a 2.5MW power conversion system, achieving an annual production capacity of 5GWh. Joshi remarked, “As more renewable energy flows into our grid, reliable and scalable energy storage will be essential. Projects like this bring us closer to our goal of 500GW of non-fossil fuel capacity by 2030.”

In a recent guest blog for Energy-Storage.News, Debmalya Sen, president of the India Energy Storage Alliance (IESA), pointed out the government’s commitment to stimulating energy storage deployment through tenders and incentive programs, along with the need to promote domestic supply chains. While the manufacturing of battery cells—considered the most complex part of the value chain—has yet to gain traction in India, it is anticipated that the country will achieve 225GWh of annual battery pack production capacity by the end of the decade.

The Central Electricity Authority (CEA) has indicated that energy storage should be mandatory in solar PV tenders, projecting a significant need for pumped hydro energy storage (PHES) to provide long-duration energy storage alongside BESS. Karnataka’s minister KJ George mentioned plans for a 2GW battery storage project and the implementation of three PHES plants, including the 2GW Sharavathi project, 1.5GW Varahi project, and 1GW Pavagada project. Additionally, state-owned power producer NTPC is piloting flow battery storage and a carbon dioxide-based long-duration energy storage technology from Italian company Energy Dome.
