Wind adds Ontario energy mix share

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).

“Ontario’s electricity 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 Bruce Campbell.

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 Energy Association.

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. .
