Waaree Energy Storage Solution Limited (WESSL), a subsidiary of Waaree Energies Limited, will establish a 16 GWh lithium-ion battery gigafactory. The facility will cover cell manufacturing, battery packs, and large-scale battery energy storage systems (BESS). It will be situated at Rambilli in the Anakapalli district of Andhra Pradesh, India.

WESSL will invest Rs 81.75 billion in the gigafactory. Furthermore, the project received in-principle approval from the Andhra Pradesh State Investment Promotion Board. Moreover, it is expected to generate around 3,000 direct jobs.

In the same month, WESSL secured Rs 10.03 billion in funding from a group of strategic investors. The investment will be used to establish a 20 GWh advanced lithium-ion cell and battery pack manufacturing facility.
