EN4 Customer Electricity Intensity
| Kilowatt-hours/account/year | F2005 | F2006 | F2007 | F2008 | F2009 |
|---|---|---|---|---|---|
| Residential - not weather normalized | 10,610 | 10,842 | 11,049 | 11,239 | 11,240 |
| Residential - weather normalized | 10,841 | 11,041 | 10,950 | 10,860 | 10,660 |
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 2009 was 11,240 kWh/account, which was 412 kWh/account or 3.80 per cent above forecast, and 1 kWh/account or 0.01 per cent above the actual billed use per account in fiscal 2008. There is upward pressure on use per account from increased penetration levels of plug-in load such as computers and home entertainment equipment. But there is also offsetting downward pressure from increases in appliance efficiency, higher electricity prices, and Power Smart programs.
The winter of fiscal 2009 was colder than normal, and was the main reason why the fiscal 2009 residential use rate was 3.80 per cent above Plan on an actual basis. However, fiscal 2009 residential use rate was 1.28 per cent below Plan on a weather normalized basis. The weather normalized variance is within the accepted industry standard of +/- 2.5 per cent.
