There's something about changing electric suppliers which is conceptually
bothersome, which is: can it have any negative consequences? The idea of
having a public monopoly grid, and people buying power through the grid
from private companies, just like we drive from one place to another on
public roads, seems fine. But I've never heard (perhaps it's just
ignorance) of any place that actually has the ability to monitor power
drawn by customers in real time, and, if their chosen supplier fails to
deliver, cut off their power, yet keep delivering power to neighboring
houses who chose other suppliers. Without that sort of infrastructure,
you can choose some unreliable supplier, yet get reliable power from
other suppliers whom you haven't paid. Or you can choose a supplier who,
although his equipment is reliable, doesn't have the capacity to meet the
afternoon air conditioning load of all his customers. Never mind... they
won't suffer; other suppliers will pick up the load... until everybody
starts thinking that way. This seems like a perfect recipe for a race to
the bottom: competition on prices, without regard to quality. That it
hasn't gone bad yet doesn't mean it won't; people quite likely are
reluctant to start the race to the bottom, yet it'd be a mistake to trust
the goodwill of all of them, forever.
I've heard of large industrial customers having to turn off their power
at times of high load, as per prior agreement with their suppliers, but
never residential customers. Yet that seems, in theory, to be the only
way to make supplier choice a truly meaningful activity.
Perhaps one of you would care to leave off the red-state-vs-blue-state
sniping for long enough to consider this and tell me why I'm ignorant or
misguided.
