Courtesy: Affiliated Engineers Inc. Uninterruptible power supply (UPS) systems have been a familiar presence for years, known for their ability to enhance power quality and offer continuous power for critical loads. These systems typically supply power for a few minutes while the generator starts up.
UPS is focused on providing immediate, short-term power backup during interruptions, ensuring continuous operation of critical systems for a limited duration. BESS is designed for long-term energy storage and management, supporting renewable energy integration and providing power over extended periods.
If accessory power is needed for heating, ventilation and air conditioning (HVAC), ensure it comes from a source recognized as “legally required standby” under NEC 701. IFC 1207.7.4 stipulates a two-hour fire barrier separation requirement if the BESS is installed inside a building that is not dedicated for its use.
If the BESS is in a “dedicated use” building compliant with IFC 1207.7.1, then the kilowatt-hour limits outlined in the table do not apply. This exception is beneficial, especially considering that 600 kWh of energy capacity is approximately equal to a small portable diesel generator's belly tank capacity.
