The selection process is being conducted through a two-stage Quality and Cost Based Selection (QCBS) mechanism on the Central Public Procurement Portal.
The ACC battery storage PLI scheme was approved by the Union Cabinet in May 2021 with a budgetary outlay of ₹18,100 crore. It aims to develop 50 GWh of domestic ACC manufacturing capacity and encourage major domestic and international companies to establish globally competitive battery manufacturing facilities in India.
Although beneficiaries were awarded 40 GWh (gigawatt-hours) of battery-cell capacity, production has barely begun. Apart from Bhavish Aggarwal-led Ola Cell Technologies, no PLI beneficiary has set up cell-manufacturing capacity. Reliance Industries Ltd (RIL), through its subsidiaries Reliance New Energy Battery Ltd and Reliance New Energy Battery Storage Ltd, was awarded 15 GWh of capacity under the ACC PLI scheme. No cell maker has received an incentive yet.

The latest 10 GWh tender is particularly significant as it targets grid-scale stationary storage, a segment expected to gain importance as India expands its renewable energy capacity and requires larger energy-storage systems to manage intermittent power generation.
The participation of 22 companies highlights growing industry interest in India's energy-storage manufacturing opportunity. The next stage of the selection process will determine which bidders qualify for the proposed capacity allocation.
