Off-Peak Electricity

As indicated on this Hydro Ottawa page the price of electricity depends on the hour you’re using it, and the rate periods are different in summer and winter. The mid-peak/on-peak times are reversed in summer and winter. Here are the respective times for Summer Weekdays (May 1st to Oct 31st); Winter Weekdays (Nov 1st to April 30th); and Weekends and Holidays:

The highest energy prices occur over the afternoon, when air-conditioning use is greatest.   There are two peak periods during the winter months: in the early morning and in the evening. During these times, increased space heating, lighting and appliance use is common.   These periods are all off-peak, both summer and winter.

Prices effective November 1, 2016:

  Off-Peak: 8.7 cents / kWh
  Mid-Peak: 13.2 cents / kWh
  On-Peak: 18.0 cents / kWh
