This is the best summary I could come up with:

"It is truly a combination of many things that occurred that got us into the rotating outage situation," Marie-France Samaroden, vice-president, grid reliability operations at AESO, said at a news conference Friday afternoon.

It's a problem Alberta hasn't experienced in more than a decade, when a July 2013 heat wave led to rolling brownouts to conserve power.

AESO also issued a grid alert on Wednesday evening this week due to unexpected outages at power plants and high demand, Samaroden said.

Blake Shaffer, an associate professor of economics at the University of Calgary specializing in electricity, called the brownouts a "far more serious situation" than the power demand crisis Alberta experienced in January.

A combination of record cold, surging power demand and some gas plants offline led Alberta to issue an emergency alert Jan. 12, pleading with the public to turn off appliances and lights to relieve an overtaxed grid.

Andrew Leach, an energy and environmental economist and professor at the University of Alberta, said the current market is skewing production, because companies don't want to generate more power when supply is high and prices are low.
