- In the mid-1990swell before FirstEnergy in Akron, Ohio, got sloppy with its tree-trimming and monitoring systems last summermathematicians, engineers, and physicists set out to explain the statistical overabundance of big blackouts. ...
- One, an optimization model, championed by Caltech's Doyle, presumes that power engineers make conscious and rational choices to focus resources on preventing smaller and more common disturbances on the lines; large blackouts occur because the grid isn't forcefully engineered to prevent them. The competing explanation, hatched by a team connected with the Oak Ridge National Laboratory in Tennessee, views blackouts as a surprisingly constructive force in an unconscious feedback loop that operates over years or decades. Blackouts spur investments to strengthen overloaded power systems, periodically counterbalancing pressures to maximize return on investment and deliver electricity at the lowest possible cost. ...
- Which of these models better explains the mechanism behind large blackouts is a matter of intensesometimes even bitterdebate. ... -Canada task force report won't eliminate large blackouts. If either conscious optimization or unconscious feedback sets up power systems to fail, then large cascading blackouts are natural facets of the power grid. ...

In the mid-1990s, Doyle, at Caltech, began to mine data on blackouts that had been collected since 1984 by the North American Electric Reliability Council, the organization in Princeton, N. ...
- Plotting the logs of the frequency of blackouts versus their magnitude, they observed that the frequency of large blackouts was much higher than they expected.
