Evaluating the Value of Energy Storage

RMI outlines three steps to help businesses evaluate the value of energy storage:

  1. Identify the primary service the battery will provide. For businesses with solar PV systems, a battery could optimize the building’s load to maximize self-consumption of PV.
  2. Identify secondary services the battery could provide. The primary use for the battery may not use its full capacity, so take some time to evaluate what services the battery could provide with its spare capacity. Secondary services include things like backup power, power quality improvements, and solar PV integration.
  3. Identify any tertiary services the battery could provide back to the grid. If your local utility offers a demand response program, the battery’s remaining capacity could be used to participate in the program, providing an additional revenue source for your business.

The energy storage business is booming, according to The US Energy Storage Monitor Report. The report, which is published quarter by GTM Research and the Energy Storage Association, said that during the second quarter of 2015, deployments increased by six-fold compared to the previous quarter.
