CALGARY, Nov. 21, 2013 /CNW/ - For the second time this week, Alberta's
demand for electricity reached an all-time high of 10,677 megawatts
(MW) at 6 p.m. yesterday.
"Winter is typically the time of year when we see the highest demand on
Alberta's power system," says Mike Law, Vice President Operations for
the Alberta Electric System Operator (AESO). "A prolonged cold front,
reduced daylight hours and overall growing demand are all factors that
combine to create the record electricity consumption levels we are
On a typical winter day in Alberta, demand fluctuates between 8,100 MW
to 10,000 MW per hour. A decrease in temperature of just one degree
Celsius equates to an additional 23 MW of electricity consumed. To help
put this into perspective, one MW of electricity serves about 1,250
Law noted that it is rather unusual for Alberta to hit new record peaks
this early in the season, in advance of the additional demand that
holiday lighting places on the system. "Having this new record come so
early in the winter is a clear indication that power demand in the
province is increasing and will only continue to go higher as our
economy grows," said Law, who wants to remind Albertans that every
little bit helps and conserving power at home is not only good for the
grid, but also reduces individual power bills.
Albertans can help reduce the demand on the electricity system by:
Running major appliances (washers, dryers, dishwashers) after 7 p.m.
Turning off unnecessary lights
Turning off non-essential electrical appliances
Connecting a timer to a vehicle's block heater
The AESO's team of highly trained experts monitors 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 are available to meet the electricity needs of all Albertans.
On November 19, Alberta's peak demand reached a high of 10,610 MW at 6
pm, breaking the previous record of 10,609 MW set on January 16, 2012.
The average daily pool price during the record peak on November 20 was
$35.46 on a scale of $0-$999.
As an independent system operator, the AESO leads the safe, reliable and
economic planning and operation of Alberta's interconnected power
system. The AESO also facilitates Alberta's fair, efficient and openly
competitive wholesale electricity market, which in 2012 had 170
participants and approximately $6.4 billion in annual energy
