Massive power outage hits Central and South Florida.

UPDATE BY BRENDAN: The outage was apparently caused by a nuclear power plant shutting down — or possibly vice versa. Quoth the AP:

Florida’s largest electric company shut down
a nuclear reactor south of Miami for safety reasons Tuesday, causing
sporadic power outages covering large portions of the state that could
last well into the night. More than 3 million people are affected, the
state says.

The Nuclear Regulatory Commission said that the two
Florida Power & Light nuclear reactors at its Turkey Point power
point 30 miles south of Miami automatically shut down. …

"We don’t
know whether the grid disturbance caused the units to shut down or that
their shut down caused the grid disturbance," said Kenneth Clark, a
spokesman at the NRC regional office in Atlanta. He said the two
reactors were automatically shut down and in safe standby.

"There are no safety concerns. The reactors shut down as designed,"
said Clark in a telephone interview.

Federal officials say there’s no indication terrorism is involved.

The Miami Herald, Orlando Sentinel, Palm Beach Post and St. Petersburg Times have more.

UPDATE 2: Lending credence to the "vice versa" theory (i.e., that "the grid disturbance caused the [nuclear] units to shut down" rather than "their shut down caused the grid disturbance"), the Palm Beach Post says "a ‘massive equipment failure’ just after 1 p.m. at an
FPL substation in Miami-Dade County caused the massive power outages
that affected parts of the state today, an FPL spokesman said." FPL stands for Florida Power & Light.

"There has been a major equipment failure at the
FPL transmission substation in South Florida that has caused major
transmission imbalances throughout the state," Public Service
Commission spokeswoman Bev Demello said today.

Something caused the protective tripping mechanisms of some
generating units to activate, which has caused rotating blackouts, she
said.

I don’t think "FPL transmission substation" and "nuclear power plant" are synonymous, so it appears we have conflicting explanations here. Lending further credence to this interpretation: the Post’s website has a separate headline stating, "Nuclear plant affected." Cause and effect are different, so I assume they’re saying the plant didn’t cause it, but was merely affected by it.

Personally, I blame some combination of butterfly ballots, Raul Castro, and Hillary Clinton, not necessarily in that order.

P.S. Oh, and Canada. Always Blame Canada.
