Our recent weather event has once again raised cries for
burying all power lines. Even here at To2C, readers have chimed in on the
issue.
It has also again highlighted the longstanding Columbia/Ellicott City divide. In some recent casual conversations I've detected a hint of an infrastructure superiority complex among someColumbians . Columbia ,
of course, was a pioneer in the burying of power lines forty five years ago. As a result, Columbia in general, suffered
fewer power outages than the rest of HoCo, percentage wise anyway.

That being said, there were still power outages in Columbia . The infrastructure
is only as strong as its weakest point which occurs in and all around Columbia . This is also
true in Ellicott City . In the newer
developments, including my own neighborhood, all of the power lines are buried.
The problem is that they are connected to the old parts where the wires are
hung on poles, the aforementioned weak link. In Ellicott City the old parts occupy a larger geographical area than the new parts.
Whether or not to
just go ahead and bury everything everywhere has been battered around for some time now. According
to this story by Mike DeBonis in The Washington
Post, “In 2005, the Maryland Public Service Commission studied whether creating
a statewide system of underground lines would be wise. The group concluded that
building such a system would be too expensive, …”
There also seems to be a question as to whether it is even worth
it.
“A 2009 report from the Edison Electric Institute, a trade
association for public utilities, said data show that underground systems have
“only a slightly better reliability performance” than above-ground systems.”
Then again, if you just measured the performance of
underground power lines in times of storms like last Fridays, putting the power in the hole wins
hands down.
“Pepco said in a 2008 report that outages involving overhead
wires took 2.8 hours to repair, while the average outage involving underground
equipment took 4.4 hours. But during and after storm events, the calculation
changed: Above-ground equipment took an average of 8.2 hours to repair, “while
there were no [underground] storm related failures for comparison.”
And then there’s that…
