  • UPS Solution(10~50kWh)

  • UTILITY Solution(>1MWh)


Energy storage offers a variety of benefits

ESS compensates for intermittency of renewable energy, such as wind and solar.

To compensate for wind and sunshine’s variability, energy storage provides stored electricity to the grid and stable power output from renewable energy.

  • Reduces output variability
  • Improves power quality
ESS can be used to defer transmission and distribution network upgrades and investment.

Using energy storage, upgrade to transmission and distribution networks can be deferred by smart management of the local peak demands.

  • Transmission support
  • Transmission congestion relief
  • Area / Frequency regulation
ESS helps grid system operators maintain constant frequency.

Energy storage based on lithium ion battery provides reliable and fast frequency response without being subject to fuel prices and with zero emissions.

ESS enables commercial and residential owners to cut energy costs.

Electricity stored during off-peak time can be used during on-peak hours so that home/commercial owners can cut peak demand and electricity cost. ESS integrated with PV can maximize consumption of solar energy by using electricity stored off-peak.

ESS can be used for curtailment of electricity from renewable energy sources.

Due to transmission constraints, currently, ever-increasing portion of wind generation is being curtailed. Energy storage is the best option for reducing renewable power curtailment, relieving transmission congestion, and achieving full utilization of renewable energy sources.
