I'm sure a full analysis will be performed after the recovery
efforts are completed.  I'm also certain the operators of
both 25 Broadway and 32 Old Slip are working very dilgently
to get them running.

But I would like to point out, no one regularly runs their
generators for 48+ hours as part of a normal test.  In addition,
most standby generators are fitted only for "limited" duration
runs.  You should expect problems during any extended run of a
generator plant.  I'm a bit surprised that 25 Broadway and
32 Old Slip are the only ones we've heard about.

Until I know a bit more about what happened, I can't say
whether any alternative design could have performed better.
