Generation companies produce the electricity we use. They include facilities powered by nuclear, hydro, natural gas, wind and solar sources. The largest generator is Ontario Power Generation – a provincially-owned company. This is how the generation mix looks in Ontario today:
Once electricity is generated, it travels across Ontario on high-voltage transmission lines. These lines, which are mostly owned and operated by Hydro One, take power from the generator to the doorsteps of local utilities. There, it is put through transformers that convert it to low-voltage power. It is then sent out on distribution lines.
Local utilities (also known as distributors) own and operate the low-voltage lines that deliver power to your home or business. They are also responsible for billing you and delivering conservation programs. See the electricity utility performance dashboards for more information about your local utility

We do not allow utilities to profit from the sale of ele...
