As batteries capable of powering buildings get bigger and cheaper, businesses are increasingly looking to install them to gain more control over their electricity costs. Unlike large battery arrays being built by utilities to feed power to the grid, these batteries are typically being built on site to cater to the needs of individual users. Installing them locally can help companies manage costs by storing power when it is cheaper to produce or buy, and tapping it when wholesale prices go up or there is a power disruption.
