Energy storage, such as battery storage or thermal energy storage, allows organizations to store renewable energy generated on-site for later use or shift building energy loads to smooth energy demand. With a large battery, for example, excess electricity generated by rooftop solar can be stored for later use. By coupling on-site renewables with energy storage, organizations can use on-site electricity for more hours of the day and further reduce emissions from energy use. Better Buildings works with partners to showcase their success with installing energy storage on their properties.
