Introduction

What is an ESS?

Energy Storage System(ESS) is a system that can store energy. Simply put, it is a huge battery.
The ESS provides solutions for applications throughout the power supply system including Grid-scale, C&I (Commercial and Industrial)
and UPS (Uninterruptible Power Supply). Its main applications include Peak Shifting, Renewable Integration, Frequency Regulation and Power Backup.

Application of ESS

Grid-scale Home | C&I | UPS
Generation Transmission & Distribution Consumption
Grid-scale

Grid-scale batteries are deployed at power plants, substations, or solar/wind farms to provide
capabilities such as peak shifting, renewable integration, and frequency regulation.

  • Peak Shifting
  • Renewable Integration
  • Frequency Regulation
C&I

C&I batteries are deployed at commercial or industrial facilities (Offices, Schools, Factories, etc.) to provide capabilities such as peak shifting and renewable integration.

  • Peak Shifting
  • Renewable Integration
UPS

UPS batteries protect Internet Data Centers and IT facilities which need a stable stream of power supply.

  • Emergency Power Backup

Grid-scale and C&I

  • Peak Shifting
    Charge during off-peak times
    Discharge during peak times
  • Renewable Integration
    Stabilize the intermittent renewable power by alternately charging and discharging
  • Frequency Regulation
    Charge when grid frequency increases
    Discharge when grid frequency decreases
