High System Reliability

In 2010, Manitoba Hydro's power outage frequency and average outage time continue to be substantially lower than the respective composite average of other utilities.

Our high system reliability is also reinforced through 11 cross-border interconnections in Canada and the United States through the Midwest Independent Transmission System Operator (MISO).

Manitoba Hydro is also a member of both the North American Electric Reliability Corporation and the Midwest Reliability Organization, which have enforcement responsibilities in this region.
