System-Wide Electricity Supply Mix 2015

At Enersource, we want to ensure that we provide our valued customers with information that is important to them.

The Ontario Energy Board (OEB) posted their system-wide supply mix data, with information updated from 2015. The system-wide supply mix is the combination of power sources used to generate the electricity consumed in Ontario.

As a regulated distributor of electricity in Ontario, and like all other local distribution companies, Enersource Hydro Mississauga is required by law (under Ontario Reg. 416/99) to disclose to our consumers information regarding the Ontario system-wide electricity supply mix. The OEB’s directive requires that this information is distributed annually. Under the same regulation, the Ministry of Energy is responsible for providing Ontario’s electricity supply mix data to electricity distributors.

Enersource’s supply mix for 2015 is as follows:

Natural Gas: 9.7%

Biomass: 0.4%

Wind: 6.4%

Nuclear Energy: 57.8%

Water: 23.2%

Solar: 1.9%

Other: 0.5%

Waste: 0%
