New Time-of-Use Electricity Prices in Ontario

New Time-of-Use Electricity Prices in Ontario

Ontario is rapidly increasing the number of SMART meters rollout out to residential electricity consumers. These consumers will eventually be rolled over to Time-Of-Use billing, which charges different rates per kilowatt hour of electricity, based on the time of day it was consumed. These prices are adjusted every six months, and new rates are effective November 1st 2008. They are:

Smart Meter

On-Peak = 8.8 cents / kwh    (was 9.3 in prior 6 month period)

Mid-Peak = 7.2 cents / kwh  (was 7.3 in prior 6 month period)

Off-Peak = 4.0 cents /kwh    (was 2.7 in prior 6 month period)

Summer Weekdays
(May 1st - Oct 31st)
7:00 a.m. to 11:00 a.m. Mid-peak 7.2
11:00 a.m. to 5:00 p.m. On-peak 8.8
5:00 p.m. to 10:00 p.m. Mid-peak 7.2
10:00 p.m. to 7:00 a.m. Off-peak 4.0
Winter Weekdays
(Nov 1st - Apr 30th)
7:00 a.m. to 11:00 a.m. On-peak 8.8
11:00 a.m. to 5:00 p.m. Mid-peak 7.2
5:00 p.m. to 8:00 p.m. On-peak 8.8
8:00 p.m. to 10:00 p.m. Mid-peak 7.2
10:00 p.m. to 7:00 a.m. Off-peak 4.0

It’s hard to say what the impact of the latest change will be on the average consumer. Though Peak and Mid-Peak rates came down a bit, the Off-Peak rate, which includes all weekends, increased almost 50%. For sure, anyone who finds their electricity plan hs switched from flat rate (5.6 cents for first 1000 kwh) to TOU, will experience an increase in billing! It’s very hard to switch that much usage to off-peak hours, but for everyone’s sake, it needs to be done.

Just how much greenhouse gas is produced to make one kilowatt/hour of electricity? We have the information listed in a chart, by State & Province, here: GHG from Electricity
