Residential electricity intensity is calculated by dividing consumption in the residential sector by the average number of residential accounts over the fiscal year.

Actual billed use per account for fiscal 2008 was 11,239 kWh/account, which was 222 kWh/account or 2.01 per cent above forecast, and 190 kWh/account or 1.72 per cent above the actual billed use per account in fiscal 2007. Use per account is rising mainly due to increased penetration levels of plug-in load such as computers and home entertainment equipment.

The winter of 2007/2008 was colder than normal and fiscal 2008 residential use rate was 2.01 per cent above Plan on an actual basis. However, fiscal 2008 residential use rate was 1.43 per cent below plan on a weather normalized basis. Both variances are within the accepted industry standard of +/- 2.5 per cent.
