Chart Ontario Energy Board
Ontario regulated electricity prices, by price plan
Publisher’s title: Ontario regulated electricity prices (time-of-use, ultra-low overnight and tiered), by the date each price took effect
The Regulated Price Plan prices the Ontario Energy Board prints on its historical rates page: time-of-use since 2006, ultra-low overnight since 2023, and the lower and higher tiered prices since 2004. Each point is the date a price took effect; it applies until the next date. The tiered plan's threshold in kilowatt-hours is words on the page and is not read. The Board marks two tiered dates with an asterisk ("Set by Government Regulation"); the asterisk is kept as the flag. The page's one-price row for December 9, 2002 (4.3 cents) has a single cell and is not read.
