Auxiliary power is electric power that is needed for HVAC for the battery stacks as well as control and communications. This sounds deceptively simple for equipment that has no moving parts, yet it is often a moving target, as BESS vendors continue to morph their designs after an order is placed.
Fire safety systems, such as fire alarms, control panels and gas ventilation systems (if present). These auxiliary loads are essential for ensuring the safe and efficient operation of BESS projects. Therefore, providing a reliable power supply for these auxiliary loads is crucial. BESS Auxiliary Power Supply Circuit Design
BESS auxiliary loads typically fall into the following three categories: ● Control and communication equipment, such as the battery management system and network switches; ● Thermal management systems, such as HVAC or chillers; ● Fire safety systems, such as fire alarms, control panels and gas ventilation systems (if present).
Therefore, providing a reliable power supply for these auxiliary loads is crucial. BESS Auxiliary Power Supply Circuit Design Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not need an external supply.
The electricity cost for auxiliary loads depends on the energy consumption (kWh) and the pricing structure set by independent system operators or utilities. For example: • In ERCOT, the BESS auxiliary load must be metered separately from energy used for battery charging and is charged at the retail rate.
When an external auxiliary power supply is required, project owners or their EPC (engineering, procurement and construction) contractors are typically responsible for designing, furnishing and installing the auxiliary power supply circuit. This includes auxiliary power transformers, switchboards and cables.
