Generally, participating in a demand response program means customers will receive some financial benefit by reducing or shifting electricity consumption during certain hours. For pricing programs, electricity prices are much cheaper during non-peak hours, while peak-hours are more expensive. This corresponds to the more expensive hours for the utilities to produce or purchase electricity to meet demand. For other demand response programs and pilots, there can be a combination of incentives and notifications to participate in upcoming demand response events. Each program has other important details such as the maximum length of an event, the number of events that can be called in a given time period, and eligibility requirements. The specific terms and conditions of demand response programs vary, which customers should understand before enrolling.
