| Florida to begin outage investigation Monday, will 
    take 'months' 
 Boston (Platts)--28Feb2008
 
 Florida Reliability Coordinating Council President and CEO Sarah Rogers
 said Thursday that an FRCC-led "event analysis team" will hold its first
 meeting on Monday March 3 as the starting point for a thorough, months-long
 analysis of Tuesday's power outages in southern and central Florida.
 
 Rogers said that the team will include five representatives from
 utilities in the state offering different types of expertise, as well as a
 team member from the North American Electric Reliability Corp., and 
    observers
 from both the Federal Energy Regulatory Commission and the Florida Public
 Service Commission.
 
 "We will be looking at why the [substation disconnect switch] failed, why
 the problem wasn't isolated to the substation," and whether the transmission
 system and load-shedding program acted as they were designed to, said 
    Rogers.
 
 Rogers said the team's analysis is likely to take "several months," and
 that its findings will be shared widely. She said that the initial analysis 
    of
 what happened on Tuesday still stands.
 
 A fault at a Florida Power & Light substation in western Dade County
 failed to be isolated, apparently because of "a malfunctioning disconnect
 switch to an inductor."
 
 That affected 26 transmission lines -- including 230-, 138- and 69-kV
 lines -- and tripped offline about 4,000 MW of generating capacity, 
    including
 two nuclear units and one gas-fired combined-cycle plant at FP&L's Turkey
 Point station, and gas-fired plants as far away as Tampa Bay and 
    Jacksonville.
 
 Rogers said that the sudden loss of those plants caused the grid's
 frequency to drop to 59.7 hertz, thereby triggering a "level A" automatic
 underfrequency load-shedding program under which 9% of the load throughout
 much of southern and central Florida was shed, mostly for between a few
 minutes and two hours.
 
 The latest count, she said, suggests that about 900,000 customers were
 cut off, including about 585,000 at FP&L, 150,000 at Progress Energy 
    Florida,
 and 59,000 at Tampa Electric.
 
 Rogers said that aside from the malfunctioning disconnect switch, the
 FP&L and state-wide grid appeared to work as they were designed to, thereby
 limiting the geographic reach, customer impact and duration of the outage.
