Midland project puts Korea on track to meet 2030 goal


Korea Midland Power has selected Kokam for the provision and installation of solar-pv connected energy storage systems in South Korea.

The 28MWh energy storage systems will be installed across nine sites with each site consisting of 8MW/28MWh.

The projects are expected to be operational by the end of 2018.

The installation is part of the “Renewable Energy 2030” plan, in which South Korea aims to increase its renewable energy in the total energy mix from 4% in 2016 to 20% by 2030.

The South Korean government is incentivising the installation of energy storage systems integrated with solar energy.

In addition, a Renewable Energy Certificate (REC) weight of 5.0 is being granted to electricity discharged from energy storage systems coupled to PV power systems during off-peak times (before 10:00 am and after 4:00 pm).

The aim is to address problems caused by the intermittent energy generation of renewable resources.

The energy storage systems will contain Kokam’s new 100 Ah HE NMC cell, a Battery Management System, a Battery Protection Unit, and firefighting systems.

The battery modules use flame-retardant materials, further increasing the safety of the ESS.

The 100 Ah HE NMC cell includes a new active material in the anode and includes a new additive to the cell’s electrolytes, increasing the cell’s energy density by 26%, to 204.4WH per kilogram, without reducing its expected life.

This helps renewable energy project developers lower the levelised cost of energy (LCOE) and increase the return on investment.

Kokam has also won a contract with renewable energy developer Razzler for the delivery of 5MW/ 12 MWh energy storage system connected to a total of 5 MW PV system capacity.
