Most power outages that hit your facilities last two hours or less. Given that short duration, is a generator really the best response when the lights go out? Using battery energy storage systems (BESS) for outage response could give you more effective facility power resilience.

One reason for this is the immediate response a BESS delivers. Stored energy can provide sub-second load pickup, which protects sensitive industrial equipment from seconds-long power interruptions that occur when generators ramp up. Even those brief outages can push machinery offline and lead to downtime.

This Ask the Expert dialogue illustrates how and why facilities might want to add BESS to their outage management strategy. PowerSecure’s Joaquin Aguerre, strategic portfolio director, and Todd Jackson, vice president, utility sales, will cover:

  • How energy storage and generators fit together
  • Why stored energy cuts maintenance and prolongs the life of generation resources
  • What load shifting is and how it can provide you with cost savings

Along with providing grid outage protection, stored energy can lower a company’s Scope 2 emissions.
