Waaree Energy Storage Solutions, a subsidiary of Waaree Energies, has commenced operations at its 5.15 GWh battery energy storage container manufacturing facility in India.

The company said it expanded the facility’s planned battery storage container manufacturing capacity from 3.5 GWh to 5.15 GWh following production debottlenecking and improvements in battery cell energy density.

The battery storage container manufacturing plant is designed to produce battery storage containers for utility-scale, commercial, and industrial applications.  The manufacturing facility is part of its planned 20 GWh roadmap for energy storage manufacturing by FY 2028.

It incorporates Industry 4.0 technologies, automated guided vehicles and assembly lines, intelligent material-handling systems, and testing and quality-assurance systems.

Waaree also intends to operationalize 5.15 GWh of battery-pack manufacturing capacity in this financial year, up from the originally planned 3.5 GWh, as well as a 3.5 GWh lithium-cell manufacturing facility.

In February 2026, it announced plans to set up a 16 GWh integrated lithium-ion battery manufacturing plant in Rambilli, Anakapalli, Andhra Pradesh, with an investment of ₹81.75 billion (~$901.26 million). The integrated greenfield lithium-ion manufacturing plant covers the entire battery value chain.

In January 2026, Waaree Energy Storage Solutions secured ₹10.03 billion (~$111.16 million) in funding from a group of strategic investors, including family offices, high-net-worth individuals, and institutional backers, to develop a 20 GWh cell-and-battery-pack manufacturing facility.

In March 2026, the company broke ground on a 10 GW integrated solar ingot-and-wafer manufacturing facility in Nagpur, Maharashtra, with an investment of approximately ₹62 billion (~$671.60 million).

In FY 2026, Waaree Energies’ revenue rose by 83.7% YoY to ₹265.37 billion (~$2.79 billion) from ₹144.45 billion (~$1.52 billion). Its module production capacity increased 71% YoY from 7.1 GW to 12.6 GW, and cell production capacity rose from 100 MW to 2.3 GW. It is also planning capacity expansions in batteries, solar cells, ingot wafers, and green hydrogen electrolyzers.

According to Mercom’s India Solar Market Leaderboard 2026, Waaree Energies was one of the top solar module suppliers in 2025.
