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.
The cost of the auxiliary power supply circuit and any required backup power sources must be accounted for in the project's capital expenditures. Project owners are also responsible for the electricity costs associated with the BESS auxiliary load during operation.
This includes auxiliary power transformers, switchboards and cables. The auxiliary power supply circuit must be designed to meet the BESS product's technical requirements, which vary by product. For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V.
One critical but often overlooked aspect of BESS project development is the technical requirements and financial implications of BESS auxiliary power. In addition to the power required to charge its batteries, a BESS also requires power for its auxiliary loads. BESS auxiliary loads typically fall into the following three categories:
For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V. The circuit must also be sized based on the peak auxiliary load of the selected BESS product and the specific project configuration. Each BESS product has a unique auxiliary load design and peak auxiliary load.
