Battery costs have fallen more than 85% since 2010, causing many commercial and industrial facilities to consider installing a battery energy storage system for backup power as part of the facility’s energy system. But batteries can also be used daily to reduce energy consumption and peak demand, resulting in reduced electricity bills.

Right sizing a battery energy storage system for such benefits is a tricky equation that needs to factor in consumption patterns and electricity rate structures as well as cost avoidance and revenue potential. This white paper walks through the steps any commercial or industrial facility should take to determine a battery size that offers the best return on investment.
