National and provincial policies within Canada are pushing towards a future which relies on sustainable production and consumption of energy, and the reliability of the power grid plays a critical role in ensuring these policies can succeed. From an operational standpoint, one of the most significant issues facing the power industry is improving the situational awareness (SA) of grid operators, defined as "the perception of the elements in the environment within a volume of time and space, the comprehension of their meaning, and the projection of their status in the near future." The critical importance of SA was shown most recently in the August 2003 blackout, where a lack of SA was listed as one of the root causes of the blackout that affected an estimated 50 million people with estimated costs in the range of $4 to $10 billion US dollars.
