Mercury plunges; power consumption soars
"The heaviest demand for electricity in Alberta typically occurs during the winter," says Warren Frost, Alberta Electric System Operator (AESO) vice-president of Operations and Reliability. "A prolonged cold snap, reduced daylight hours and increased lighting are all factors that combine to push demand to record levels."
The AESO's system controllers monitor the electricity grid 24 hours per day, seven days per week, working collaboratively with transmission facility owners and power generation owners to ensure that even during times of high demand, contingency plans are in place and reserves available to meet the electricity demands of all Albertans.
Electricity consumption in Alberta has grown by 29% since 2000 with a year over year average load growth of 3.2% each year for the last five years. The AESO estimates an additional 5000 MW of electricity supply by 2017 and 11,500 MW by 2027 will be required to meet the growing electricity demands of Albertans.

LONDON - Only one in 10 of the world’s electric utility companies are prioritising investment in clean renewable energy over growing their capacity of fossil fuel power plants, according to research from the University of Oxford.
The study of more than 3,000 utilities found most remain heavily invested in fossil fuels despite international efforts to reduce greenhouse gas emissions, and some are actively expanding their portfolio of polluting power plants.
The majority of the utility companies, many of which are state owned, have made little change to their generation portfolio in recent years.
Only 10% of the companies in the…
