An optimal power factor rating depends on the specific electrical system and the goals of the operator. In general, a power factor rating close to unity (1.0) is considered optimal/Energy Efficient because it indicates that the electrical system is using power efficiently and effectively.

Power factor is a measure of how effectively electrical power is being used in a system. A power factor of 1.0 means that all the electrical power being supplied is being used effectively to perform useful work, while a power factor less than 1.0 indicates that some of the electrical power is being wasted.

In some cases, electrical systems may have a lower power factor due to the nature of the load. For example, inductive loads like motors or transformers can cause the power factor to drop below 1.0. In these cases, operators may want to consider installing power factor correction equipment to improve efficiency and reduce wasted energy leading to a responsible level of energy sustainability.

Ultimately, the optimal power factor rating will depend on the specific electrical system and the goals of the operator. A qualified electrical engineer can help determine the best power factor rating for a given system.
