I don't work at the plant; so, take this with a grain.
Yesterday, one of the buildings was photographed with dark smoke pouring out. There were not any press releases on that count, but this morning there was only normal operations.
(According to MSNBC) A few hours ago, three nonNukes went offline with the Turkey Point Station. There have yet to be any major releases of information from corporates or Homeland Security.
Seems power is coming back up right now. Remember what I said about the grain of salt?
I am sure one of the regulars will update us as soon as the corporates allow dispersals.
=====================
update_1
"CNN reported that eight power plants in South Florida in the Miami area were out of service."
http://www.reuters.com/article/rbssFinancialServicesAndRealEstateNews/idUSN2635797520080226"NEW YORK, Feb 26 (Reuters) - Both 693-megawatt units of FPL Group Inc's (FPL.N: Quote, Profile, Research) Turkey Point power plant in Florida shut [down] due to the loss of off-site power, a spokeswoman for the plant said Tuesday."
http://uk.reuters.com/article/oilRpt/idUKN2635797520080226This seems to be a major grid problem, not a nuke problem. The sited shutdown was a safety measure.
=====================
update_2
The failure was caused by defective equipment in a (west) Miami-Dade substation. This last bit of information was reported by MSNBC without reference.
All power should be restored by 17:30 EST (MSNBC).
I am still not sure what the smoke was from at Turkey Point yesterday; seems inconsequential now.
