While modern power systems reduce the risk of downtime, the need for energy storage still exists. Energy storage is used for those times when bridge time is needed – to bridge the power between utility failure and the 10 to 15 seconds it takes for emergency power to become available, usually with on-site generators.

Evolution in supercapacitor technology presents an attractive alternative to battery (Li-ION, VRLA, Sodium or Zinc-based) solutions. A great example of these advancements is Musashi Energy Solutions’ (MES) Hybrid SuperCapacitor (HSC) based solution for the 10-second bridging needs of the modern Emergency Power Supply System.
