In many places, access to grid power can be unreliable or even unavailable which cause difficulties for businesses and households. Many businesses have needs for backup power, or uninterrupted power, even where grid outages are rare.
Battery storage systems offer an excellent reserve of energy for these situations. They require no fuel to operate, when charged, and can be paired with multiple sources of energy, including, solar, wind, and generators, depending on the circumstance.
Backup provides additional benefits for battery projects that are primarily designed to bring down demand costs or to make buildings' energy use more efficient.
To properly size a backup power system, it is important to develop a profile of energy usage and to decide what is critical to be backed-up for the most beneficial investment.
