Kokam has secured a contract from Korea Electric Power Corporation (KEPCO) to develop 36-megawatt (MW) system / 13-megawatt hour (MWh) energy storage system (ESS) for frequency regulation at the Non-Gang substation in South Korea.

The project features a combination of two unique Kokam Lithium Ion battery technologies — its Ultra High Power Nickel Manganese Cobalt (NMC) battery technology and its NANO battery technology. Work on the project began in June 2016 and is scheduled to be completed by December of 2016.

In March, Kokam announced that it had successfully deployed for KEPCO two Ultra High Power NMC ESSs — a 24MW system / 9 MWh and a 16 MW / 6 MWh system — along with a 16MW / 5MWh Lithium Titanate Oxide (LTO) system. Together these systems currently provide KEPCO with 56 MW of energy storage capacity for frequency regulation.

When the new 36MW/13MWh ESS project is completed, Kokam will have deployed 92 MW of energy storage capacity for frequency regulation for KEPCO, and the total worldwide capacity of ESSs using Kokam batteries will total 132MW.

Kokam's Power Solutions Division vice president Ike Hong said: "We look forward to deploying this new 36 MW ESS for KEPCO and continuing to support its effort to install 500 MW of energy storage capacity for frequency regulation by the end of 2017.

"Based on our advanced Ultra High Power NMC and NANO battery technologies, this ESS will provide KEPCO with the industry-leading performance, reliability and cycle life characteristics that they have come to expect from Kokam, enabling them to achieve a strong return on their energy storage investment."
