FAQs 6

What is auxiliary power consumption?

Auxiliary power consumption refers to the energy used by electrical auxiliaries necessary for the operation of a power plant, which can adversely affect the heat rate and overall efficiency of electricity generation. How useful is this definition? You might find these chapters and articles relevant to this topic.

What is the electricity cost for auxiliary loads?

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.

What is a typical auxiliary power consumption profile?

A typical auxiliary power consumption profile of a vessel journey consists of a steady base hotel load and transient thruster use when maneuvering in harbors. The magnitude of thruster power peaks is typically at least twofold compared to the base load .

How much auxiliary power does a power plant use?

In other studies, various power producers have estimated the auxiliary power requirements of their units. Study of Power Plants in India: Table 15.5 summarizes an analysis of auxiliary power consumption in India’s power plants. This analysis suggests that consumption ranges from 6.33 to 8.89 percent. Table 15.5.

How does thermal management affect auxiliary power consumption?

Thermal management of a BESS, which depends on the local climate, operational use case, and the general configuration of the system, may constitute a sig-nificant proportion of auxiliary power consumption over the life-time of a facility. In some cases, auxiliary loads may be accounted separately from eficiency losses if served by an external feed.

What are auxiliary power supplies?

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.
