Most households and small businesses pay time-of-use electricity prices that appear on the “Electricity” line of the
bill. As the regulator, the OEB sets electricity prices twice a year: May 1 and November 1. Prices are based on the
estimated cost to supply electricity in the province for the next six months.
DELIVERY
This is made up of two separate costs. Both are approved bythe OEB.
1. TRANSMISSION
Power flows from Ontario power plants and other sources, through transmission lines, to your local utility. Every home
in Ontario pays the same rate to cover these costs.
2. DISTRIBUTION
A distribution company (also called “distributor” or “local utility”) delivers electricity to homes and businesses
through a network of power lines within the communities it serves.
REGULATORY
This is made up of the costs to administer the wholesale electricity system and maintain the reliability of the provincial
grid. It also includes costs for funding Ministry of Energy conservation, renewable and low-income energy programs.
GLOBAL ADJUSTMENT AND ENERGY CONTRACTS
If you buy electricity from your utility, the electricity price already includes your share of the “Global Adjustment.”
If
you sign a contract with an energy retailer, you pay the
agreed-upon contract price (not time-of-use or tiered
prices set by the OEB). You will also need to pay your
share of the Global Adjustment. It will appear as a new, separate line on your utility bill.

TIME-OF-USE ELECTRICITY PRICES
Households and small businesses in Ontario pay time-of-use prices for electricity that change according to the
TIME OF DAY and DAY OF THE WEEK. The peak periods also change by SEASON.
Your smart meter tells your utility exactly how much power you use and when you use it. With this information, your
utility charges you for the amount of power you use at off-peak, mid-peak and on-peak times.
REASONS FOR DIFFERENT PRICES
WHEN DEMAND IS LOW and fewer people are using power, lower-cost electricity is available from sources like nuclear
and large hydroelectric systems
WHEN DEMAND RISES during the day, the province’s supply of lower-cost electricity is used up, and more expensive
sources need to be used.

Evenings, weekends and holidays
¢¢ Mid-peak:
Daytime, but not the highest-use periods of the day
¢¢¢ On-peak:
The high-demand hours during the day
Summer May 1 – Oct 31
Electricity use peaks during the hottest part of the afternoon, when air conditioners are running on high.
Winter Nov 1 – Apr 30
Less daylight means electricity use peaks twice: once in the morning when people wake up and turn on their lights and
appliances, and again when people get home from work.
MANAGING YOUR ELECTRICITY USE
Did you know about 60% of energy costs in a typical home are spent on heating and cooling? To manage electricity use, try
conserving power and shifting some usage to evenings and weekends. Visit these websites for more tips:
