Jeff Dagle, an electrical engineer who has studied power reliability for the U.S. Department of Energy, said a lightning strike alone should not have caused the massive blackouts.

"My guess is that there were some other conditions there that made it ripe for this cascading event to occur," said Dagle, who works at the Pacific Northwest National Laboratory, in Richland, Wash. "Maybe some critical equipment was out of service, or not enough reserve margin was available."

Interesting. Thanks.

I think the power station already said there was no lightening, but some in the news are still propagating the myth.

I know that it's hot in the east but was there a known critical strain on the system? And why would Canada first blame lightning, then the United States. I find this really odd, particularly if there were other critical factors in play.
