Power Demand Demand is the average energy consumed over a specified

period of time. The interval is usually determined by the utility

company and is typically 15 or 30 minutes. The utility measures

the maximum demand over the 15 or 30 minute period. Utility

companies must install larger equipment to handle irregular

demand requirements. For this reason utility companies may

charge large customers an additional fee for irregular power

usage during peak times. If the maximum demand is greater

than the average consumption, the utility company will need to

provide increased generating capacity to satisfy the higher

demand. Demand is usually low in the morning and evening.

During the day there is more demand for electrical power.

Siemens power meters have a sliding window adjustment that

allows the user to monitor time segments specified by the

utility company.
