Batteries and Energy Storage

Energy storage enables you to manage when and how your energy is used.

Energy Storage Systems (ESS) have emerged as a promising, versatile technology that can provide solutions to many electric-grid challenges. Without the ability to store large amounts of energy, conventional power systems have been reliant on matching supply and demand in real-time. However, with recent advances in storage technology and significant cost reductions, energy storage has never been simpler.

There are a wide-variety of applications for energy storage, including:

  • Electric Bill Management
  • Consumption of Onsite Generation
  • Demand Response
  • Backup Power/Microgrid Support
  • Ancillary Services

Advanced energy storage systems enable users to store excess energy to be used at a later time. The systems are rechargeable and allow for electrochemical, mechanical, or thermal energy storage.
