Electricity is deregulated in two Canadian provinces: Ontario and Alberta. Both markets showed price spikes in the first year of dereguation, but then settled down into a volatile but reasonably stable environment. Alberta's market is dominated by fossil fuel generation and as such reacts more closely to the price of natural gas. Ontario's generation mix is about 50% nuclear.
Electric utilities are responsible for the distribution, or delivery, of electricity to the customers who live in their service area. The electric utilities also employ the lineman that restore your power after a major weather event and repair the downed power lines and damaged poles. Every month you will see a delivery charge on your electricity bill. This is for the transmission and distribution of electricity to your home or business. The amount charged for the delivery of electricity is still regulated by your state’s public utility commission. These delivery rates are subject to change at least twice a year and they pay for the maintenance and operation of the poles and wires that serve your residence or business.
The more cool air you lose, the harder your air conditioning unit works and the higher your electricity bill will be. Install blinds, hang curtains or get storm windows made to keep cool air from seeping out. Even mesh screens, on the outside of your home, will help deflect solar radiation. You might even consider replacing old windows that leak cold air and let in heat.
