Grid Application

Energy Storage Systems(ESS) help to stabilize power supply of traditional power plants and renewable energy generating facilities through frequency regulation and peak shifting by integrating batteries to them.

Peak Shiffing

Peak Shifting
  • ·Charge during off-peak times
  • ·Discharge during peak times

Discharge during peak times

Discharge during peak times
  • ·Stabilization of intermittent renewable power through charging and
    discharging

Frequency Regulation

Frequency Regulation
  • ·Charge when grid frequency increases.
  • ·Discharge when grid frequency
    decreases
Residential & Commercial

By using Energy Storage Systems(ESS), households can save energy generated from solar panels to use it
at times when electricity prices are high or there is a power-cut. Furthermore, Energy Storage Systems(ESS) make it possible to be completely independent from the grid.

Residential Energy Storage

Electricity Bill Saving
  • ·Charge during off-peak times where electricity rate is low
  • ·Discharge during peak times where electricity rate is high
Self-consumption
  • ·Store solar energy generated from Photovoltaic (PV) panels allowing an energy self-consumption
Emergency Power Back-up
  • ·Discharge during a black-out, functioning as a power back-up
UPS(Uninterruptible Power Supply)

Energy Storage System(ESS) can be also used to protect Internet Data Centers and IT facilities which need a stable stream of power supply.

Charged by Grid & Back-up by UPS when blackout

Emergency Power Back-up
  • ·Provide back-up power stored in a lithium-ion battery during
    black-out or unstable power fluctuation time.
  • ·Secure a stable power supply to :
    • -Telecommunication repeaters
    • -Base stations
    • -Internet data centers
    • -Other telecommunication equipment
