Product Type

ESS can be applied to frequency regulation, peak shaving, and renewable integration. Renewable integration is often used for micro-grid in lieu of a conventional generator (diesel generator) in individual islands and deserts.

Peak Shaving

HVDC(High Voltage Direct Current transmission)
Uses

Ensure profitability by charging electricity when the cost (rate) is low and discharging it when cost is high

Shifting of maximum electricity demand time (Peak shifting)

Discharging Duration Over 2 Hours
Benefits

Consumer: reduces electricity costs

System operator: reduces risk of power shortage during peak time and reduces the investment costs for building more power plants.

Key Customers End-users
Installations

In 2012, as a domestic supply business, a 250kW/500kWh ESS was installed in Guri Agro-Fishery Market

A 6MW/32MWh ESS was installed at the Busan plant of Dongkuk Steel Mill Co., Ltd.

Frequency Regulator

HVDC(High Voltage Direct Current transmission)
Uses

Gird Assistance System: Provide emergency reserve

Power Quality Improvement: Adjust frequency of generated power

Discharging Duration 15~30 Mins. (Frequency Regulation)
Benefits

Electricity company: improves efficiency of existing generators

System operator: operates the grid system operation in a more stable manner thanks to quicker response and improves power quality

Key Customers Power Generator
Installations

4MW ESS to provide reserve power of Jeju's Jeochun substation and management of active / reactive power

48MW ESS for frequency regulation at Gimje substation

Renewable Integration

HVDC(High Voltage Direct Current transmission)
Uses

Electric energy supply at peak electricity demand time (REC profit obtained from weight differences)

Variation control of wind power and solar power output

Postponed investment for power system transmission capacity expansion

Discharging Duration 3~4 Hours
Benefits

Renewable power generation company: achieves additional gains by making use of REC weight differences after storage

System operator: resolves the instability of the power grid and saves the cost of operating the whole power grid by controlling waste or shortages of electricity
