Read the evidence
Check the service address, energy type, account identifier and meter identifier before calculating. An account can contain more than one service, and the name on the envelope is not enough to identify the consumption being billed.
In Alberta, the site identifier locates the service, while the meter number identifies the device. Copy identifiers only into your private records.
In shared practice, use the fictional labels provided here. A mismatch is a reason to ask for clarification, not proof that a utility has made an error.
Your turn
Synthetic records show Cedar home electricity, site CEDAR-01, meter M104, and Cedar workshop electricity, site CEDAR-02, meter M209. The document under review says CEDAR-02 and M209.
Identify the matching service and state why the household’s meter reading cannot verify this document.
Response location: Identity and period, practice 2. Attempt this before opening the model.
Worked response
The bill is for Cedar workshop. A reading from home meter M104 cannot verify workshop meter M209.
Both the site and device point to the workshop. Similar names and a shared owner do not make two measurement points interchangeable.
Check your work: Include the workshop name and both meter labels in your comparison.
