Canonical Definition
A load profile is a representation of how a customer's (or customer class's) electricity usage varies over time, typically plotted as demand across the hours of a day, days of a week, or seasons of a year. Utilities use load profiles for rate design, billing settlement in competitive markets for customers without interval meters, and load forecasting. A customer's load profile reflects their appliance mix, schedule, and weather sensitivity.
Plain Language
A load profile is a pattern showing how your power use rises and falls over time. It can be hour by hour or season by season. Many homes use little power overnight and the most in the early evening. Utilities use these patterns to design rates. They also use them to estimate when groups of customers use power. Your own pattern depends on your appliances, habits, and the weather.
Simplest Explanation
A load profile is a picture of when you use power during the day. It might show little use at night. Then it shows lots in the evening when everyone is home.
Do Not Say
- ✕Do not infer specific household activities or occupancy from a load profile when speaking with customers.
- ✕Do not claim the utility has detailed measured profiles for every customer; some are estimated from customer-class averages.
