Elexon Load Profiles represent the pattern of electricity usage by day and by year for the average customer in each one of the eight Profile Classes.

The Profiles (daily, seasonal, yearly, per day type, etc.) are created for each of the eight Profile Classes by randomly selecting sites and installing half-hourly meters at these sites or getting half-hourly consumption data directly from Suppliers. The profiles are useful to convert annual (or similar) demand figures to half-hourly demand figures.

Profile Classes 1 and 2 are for domestic premises and Profile Classes 3 to 8 are for non-domestic premises. The eight generic Profile Classes were chosen as they represented large populations of similar customers. Below is a detailed description of these:

• Profile Class 1 – Domestic Unrestricted Customers
• Profile Class 2 – Domestic Economy 7 Customers
• Profile Class 3 – Non-Domestic Unrestricted Customers
• Profile Class 4 – Non-Domestic Economy 7 Customers
• Profile Class 5 – Non-Domestic Maximum Demand Customers with a Peak Load Factor of less than 20%
• Profile Class 6 – Non-Domestic Maximum Demand Customers with a Peak Load Factor between 20% and 30%
• Profile Class 7 – Non-Domestic Maximum Demand Customers with a Peak Load Factor between 30% and 40%
• Profile Class 8 – Non-Domestic Maximum Demand Customers with a Peak Load Factor over 40%
