South Korean-based battery manufacturer Kokam has deployed two new energy systems with a combined energy storage capacity of 40MW for Korea Electric Power Corp (KEPCO).
The two lithium nickel manganese cobalt (NMC) oxide energy storage systems (ESS) include a 24MW system / 9MWh, and a 16MW / 6MWh system.
Last August, Kokam had installed energy systems with a capacity 16MW / 5MWh at KEPCO.
With the latest energy systems installations, Kokam now provides KEPCO with 56MW of energy storage capacity for frequency regulation.
Kokam claims that the 24MW energy system is the world's largest lithium NMC energy storage system used for frequency regulation.
The 56MW storage capacity system is part of its ESS frequency regulation project, which aims to deploy 500MW of batteries by 2017.
The two new installations at KEPCO use ultra high-power NMC technology that has been designed by Kokam for the wind and solar power system, voltage support, and UPS.
These systems also help in improving power grid reliability, and cut environmental impact due to less burning of fossil fuels required for frequency regulation.
Kokam power solutions division vice-president Ike Hong said: "Our energy storage systems provide KEPCO with the performance it needs to precisely and cost-effectively regulate frequency on the South Korean grid, helping it ensure the stability of this grid, improve its operational efficiency and lower its greenhouse gas emissions."
