Where should voltage reduction for load reduction be performed?

Voltage reduction for load reduction is ideally performed on the distribution system due to the nature and structure of electric power systems. The distribution system is the final stage in the delivery of electricity to consumers, where voltage levels are typically lower and closer to end users.

By reducing voltage in the distribution system, utilities can effectively manage peak loads and reduce energy consumption without significantly impacting the reliability of service to consumers. This method is often employed during high-demand periods, allowing for a more immediate and localized impact on reducing load compared to other levels of the power system.

Performing voltage reductions at the transmission system may not provide the same level of localized control or immediacy in addressing load issues directly affecting consumers. While adjustments at generator facilities and transmission capacitor banks play roles in overall system stability and efficiency, they do not specifically target load reduction at the consumer level like distribution system adjustments do. Thus, adjustments made at the generator facilities or at capacitor banks are more focused on balancing generation and maintaining voltage stability rather than managing consumer load directly.

Overall, voltage reduction at the distribution level offers a pragmatic approach to load management that directly corresponds to consumer energy use patterns.
