## Long-Term 15-Year Availability Contracts at 220 kV Nodes

Under the awarded Battery Energy Storage Purchase Agreements (BESPAs), the 2-hour duration facilities will be connected across strategic 220 kV and 132 kV transmission substations in Maharashtra.

The battery installations will provide round-the-clock peak power dispatch, automated secondary frequency reserve, and local reactive power support to heavy agricultural and industrial pump loads.

## Standardized Substation Skid Architecture

Oriana Power will deploy modular LFP battery container skids paired with outdoor bidirectional power conversion inverters and step-up dry-type transformers.

Project commissioning will take place in phased tranches through late 2027, accelerating Maharashtra’s goal of integrating 25 GW of renewable capacity into its state grid.
