Pace Digitek has received an order from Solar Energy Corporation of India (SECI) to supply a 600 MW/1,200 MWh standalone grid-connected battery energy storage system (BESS) in Andhra Pradesh.

The total order value is ₹11.59 billion (~$131.93 million).

The tender was floated in August this year.

The scope of work includes the design and engineering of the complete BESS and its associated components. It involves the supply of BESS direct-current (DC) blocks equipped with heating, ventilation, and air conditioning, and a fire protection system. The supply also covers the power conversion system (PCS), the battery management system (BMS), and the energy management system (EMS).

Pace Digitek must integrate the BMS and EMS with the PCS and carry out cabling from the BESS DC blocks to the PCS. It is responsible for testing and commissioning of the entire BESS, including the batteries, PCS, and EMS.

It must also perform a plant performance demonstration and trial operation of the complete system, along with all related equipment and materials.

Pace Digitek will provide comprehensive maintenance for the entire system for ten years from the date of commissioning.

Pace must supply 50% of the awarded capacity within 11 months from the effective date of the contract agreement and complete 100% of the supply within 13 months.

Post the supply, testing and commissioning must be completed for 50% of the DC package within 14 months and for 100%  within 16 months.

The BESS capacity will be discharged through power exchanges during the hours specified by SECI.

The BESS will be interconnected with the Kurnool-3 Substation of the interstate transmission system network for implementing a market-based operation of BESS at Kolimigundla, Nandyal District.

The project is eligible for viability gap funding under Tranche-II.

India added 48.4 MWh of energy storage capacity in the first half (1H) of 2025, a 74% decline from 186 MWh added in the same period last year, according to the newly released India’s Energy Storage Landscape 1H 2025 Report by Mercom India Research.

India’s cumulative installed energy storage capacity reached 490 MWh by the end of June 2025.
