What is a Load Profile?
A Load Profile represents the pattern of electricity usage by day and by year for the average customer in one of eight Profile Classes.
Profile Classes 1 and 2 are for domestic premises and Classes 3 to 8 are for non-domestic premises.
We create Profiles for each of these Profile Classes by randomly selecting sites and installing half-hourly meters at these sites or get half-hourly consumption data direct from Suppliers. These samples are designed to provide profiles that are representative of all meters in this Profile Class.
- 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 (MD) Customers with a Peak Load Factor (LF) 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%
For more information, please read Load Profiles and their use in electricity Settlement.
How are Profile Classes allocated?
The method of allocating a Profile Class is dependent on whether:
- the Metering System Identifier (MSID) is Import or Export;
- meter usage is Domestic or Non-Domestic;
- the meter has ‘switched load’ capabilities;
- Maximum Demand (MD) is recorded.
More information on the allocation of Profile Classes is available from BSCP516 – Allocation of Profile Classes and SSC’s for Non Half Hourly SVA Metering Systems Registered in SMRS.
Data used in Profiling
The data collected from the samples if half-hourly consumption data. Additionally, the Profile Administrator uses temperature data from each GSP Group in the creation of Profiling data. The Supplier Volume Allocation Agent (SVAA) uses the out-turn temperature data to calculate Daily Profile Coefficients.
Approved weather stations
The temperature data is provided to the SVAA on a daily basis by the Meteorological Office and is collected for each GSP Group from weather stations that are approved for use by the Supplier Volume Allocation Group (SVG).
You can download a list of the approved weather stations from the ELEXON Portal.
