What is an Energy Storage System?

0 comment

Energy storage is a new and powerful tool for accomplishing the seemingly impossible task of matching and in many cases off-setting the grid electricity supply to the demand on a second by second basis. But this is not its only task.

  • It enables energy to be harvested when available and stored for consumption at a more optimal time, creating real cost savings.
    • To maximize energy savings by being able to store solar energy and thus use it more effectively
    • To offset consumer feed-in tariffs by being able to avoid using the grid at peak times when electricity is more expensive
  • It provides a buffer source for use in case of emergencies. Not just as a large uninterruptable power supply, but to “island” the business when utility power ceases for longer periods of time.
  • It can be a source of revenue generation, supplying the utility with needed energy within milliseconds preventing them from spinning up another larger generation source or importing it from other regions.


How does it benefit my business?

A good energy storage system (ESS) can be tied to any renewable energy system including solar or wind as well as generators or biomass, meaning you now have a tool that not only reduces overall energy demand costs but provides predictability against new and changing utility rates for the future. This provides resiliency to your critical functions while accessing all incentives currently available. Historically, the most expensive window for power rates was from mid-day to late afternoon. New utility rates changed this window to later afternoon and evening. An energy storage system addresses the fundamental problem of solar energy; specifically, the timing of solar production mismatched to the timing of energy consumption. With storage, you can save the energy you produce for when you need it most. In short, the addition of storage makes your collected energy “dispatchable.”
Most commercial businesses are dependent upon having a reliable source of power 24/7/365 and is also extremely vulnerable to shut-downs. Many facilities with solar, and without storage systems in place, discovered that during grid shut-down, their solar system no longer worked. Commercial businesses need to have the flexibility to move off the grid during any significant disruption to protect from operating lose and expensive equipment malfunction.
