Wind in 2013 increased its share to 3.4% of the province of Ontario’s energy mix, generating 5.2 terawatt hours of electricity, from 3%, or 4.6Twh, the previous year, according to Independent Electricity System Operator (IESO).
system will continue to evolve over 2014 and beyond with the introduction of
solar energy to the grid, demand response and wind generation developing critical
mass, as well as the nuclear refurbishment program,” says IESO chief executive
In 2013, nuclear was the
leading energy source with 59.2% followed by hydro 23.4%, gas 17.1%, wind, coal
2.1% and other sources 0.8%.
"We believe that
future electricity supply in Ontario should be drawn from a balanced mix of new
wind energy, in combination with natural gas and other renewable energy
sources, to ensure that Ontario has a reliable, robust and cost-competitive
electricity system," says Robert Hornung, president of the Canadian Wind
He adds that IESO believes
the contribution of wind energy to Ontario's electricity supply will increase
even more significantly in the next couple of years as new wind energy projects
come on line.
Demand for electricity in
Ontario was essentially flat at 140.7Twh versus 2012, in part due to successful
demand management practices. Flooding and an ice storm also contributed to load
losses that cut demand, according to IESO, which manages the bulk electricity
system and operates the wholesale market.
Total cost of power in 2013
was 8.55 cents per kWh, up from 7.37 cents in 2012. .
