Establishes a sales tax exemption for energy storage

S 1527 creates a sales tax exemption for commercial energy storage systems equipment and their installation costs. This directly affects businesses installing such systems on non-residential properties to store electricity for later use in heating, cooling, hot water, or power. The bill amends tax law to exempt these systems from state sales tax, covering both the equipment and installation services. Local governments must explicitly adopt this exemption in their tax ordinances to apply it.
