Regarding the "Blackout of 2003" as our news organs put it.... It has been reduced to, unfortunately, lousy preparation, overtaxed equipment and disorganization in the Midwest power grid with the originating culprit being the penny pinching First Energy.
Last August, during a particularly sweltering week, First Energy started to have problems maintaining adequate power balance on its part of the grid. This difficulty
was communicated to one of the two power distribution monitoring centers but not the other. Also, only one of the two centers had the authority to order other grid members to assist to compensate for power imbalances that First Energy was beginning to experience.
The other center was not authorized to direct, only to monitor. And its member utility companies were not even required to keep the center updated regularly on what was going on.
Needless to say, First Energey, whose equipment was particularly old and particularly not able to deal with the high energy demands from the sweltering heat, had line failures or intermittent line fluctuations that it could not keep up with. Ultimately one of its main transmission lines went down (reportedly because it sagged to low as it got hotter and touched a tree limb and tripped out (somewhere in Central Ohio).
This immediately set a teetering grid off balance altogether. What happened after that was a cascade of power surges that pushed through the center that had no control authority much less news about what was going on (in Indiana) north through Michigan and into Ontario and thence to New York and New England. As the surge swept through, power stations automatically removed themselves from the grid and shut down (safety / protection systems worked properly).
