FAQs - Energy Storage

Energy storage and how it can be used to provide backup power, grid independency and reduce energy costs.

An energy storage system (EES) is a way to store electrical energy generated from renewable power systems or generating stations within a battery-set for later discharge and usage. The type of batteries used within an energy storage system tend to be lithium-ion.

Lithium-ion batteries have a fast and almost unlimited charge/discharge cycling rate and this makes them ideal for energy storage where the application requires a battery that can recharge quickly.

A virtual power plant (VPP) is a lithium-ion based energy storage system that allows the site it is powering to run off-the-grid or off-grid when selected to do so. When a mains power supply is present the VPP charges its battery set (typically lithium-ion) and this is normally done during off-peak rate times. During peak electricity rate periods, the virtual power plant uses the energy stored within its lithium-ion batteries to support the load.
