Advantages of Energy Storage System (ESS)

MERITSUN’s Energy Storage System (ESS) provides a variety of values for the users

Energy Storage System (ESS) complements the intermittence of renewable energy produced by wind or solar power generation system. ESS stabilizes the output of renewable energy by charging & discharging irregular and intermittent power which is generated from wind and solar system. Minimizing output fluctuation / Improving power quality.

ESS can greatly reduce the investment costs for tupgrading transmission and distribution network

Power storage can manages local peak demand in a smart way, deferring the point of necessary investment for transmission and distribution network. Supplying Power Transmission / Mitigating Excessive Power Demand Region & Frequency Control.

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.
