Raw data

Well, enough time has gone by that I have decided to release my raw, unprocessed data for this work. If you end up using these data for research please cite the paper above. Let me know if you find additional errata, and I will try to update my data.

Errata

Since the publication of this paper one error and one potentially confusing item have come to my attention.

First the error. Figure 7 shows the (lack of) correlation between blackout sizes and and blackout durations. The label on the horizontal axis is "Blackout size in y2k MW." It should have been "Blackout size in y2k customers." Clearly looking at the numbers MW is not the correct messure.

Now the potentially confusing item. Table 1 shows the 15 largest blackouts, but does not include the great Toronto ice storm of 1998. Obviously this item is among the largest blackouts during this time period. However, the original NERC DAWG data for 1998 that I used for this paper did not include size information for this particular event. When the NERC data did not show size information I did not include the event, for consistency sake. Clearly this was a judgement that could have gone the other way, but c'est la vie. In fact all of the information for 1998 is goofy for some reason (a fact that is noted in the paper).
