Win,

By Arizona law you CAN switch suppliers, the lines are considered
public property... all the companies feed the same grid.

But I don't know of anyone who has switched.

I think the threat of competition has kept prices in line.

Here, we have a "Corporation Commission" that controls rates. Any
rate change request is subject to audit.

I think the main difference may be history. Out here in the wild west
EVERYTHING started out private... after all, there was no government.

Water companies were initially all private. Then, as cities
developed, multiple private companies were bought out and merged into
single-city units.

Likewise electricity. EXCEPT we had a few water districts that were
primarily for irrigation water, but discovered that dams also had
value to turn turbines and make electricity.

So, when I came to Arizona 43 years ago, all electricity was private
except Salt River Project.

By legislation, about 15 years ago now, SRP's electricity capability
became "private" in that they were subject to Corporation Commission
rules and audits, and they began paying taxes like the private
companies.

The other east-west difference, of course, is politicians. Yours are
polished and crooked as stumps. And you're so brainwashed you keep
electing them... to wit, Teddy ;-)

Our politicians are amateurs. When they do something crooked, they're
almost immediately caught, and tossed in the next election, or
sooner... like some recall election procedures currently in progress.

And then there's the situation where you THINK you're being
overcharged. You just got a "free' ride for years from a government
run entity, that undercharged for electricity, and made up the
difference with hidden taxes. They do refer to your state as
Taxachusetts don't they ?:-)
