KEPCO established a plan to build 500 MW of energy storage systems (ESS) for frequency regulation in stages over four years (2014-2017).

In 2014, for the first stage, KEPCO successfully installed 52 MW of ESS for frequency regulation across two sites, 28 MW at West-Ansung Substation and 24 MW at Shin-Yongin Substation.

KEPCO installed 28 MW (7 MWh) of Li-ion battery based energy storage for frequency regulation. Kokam provided Lithium-titanate (LTO) based Lithium Polymer battery energy storage for 16 MW / 5.4 MWh and LG Chem provided 12 MW. The ESS is currently in commercial operation as of June 2015 (Note: System testing took place before commercial operation from January 2015 to June 2015).
