The readings are taken via GPRS or PLC.

The only false reading I've ever had taken by a meter reader was one taken
electronically by the reader holding his gismo up to the circular
indentation on the meter.

That shouldn't happen! The encoding system should pretty much
guarantee error-free readings. (CRCs etc) I can only think he read the
wrong register or something. There's a lot of data stored by meters
these days, and it's easy to pull out the wrong field.

Many also have contactors built-in so that the supplier can cut you off
remotely if you don't pay your bill on time.

I can see that being fun to sort out when (not if) a typo on data entry of
meter number to account association means that some innocent person gets
cut off. True computers never lie, but garbage in garbage out. The utility
companies barely manage to administer migration from one supplier to
another with anything approaching acceptable error levels.

Yes, I know. Scary isn't it? If you think billing is complicated now
though...man you should see some of the stuff the utilities are asking
for in the next generation. I can see a time when everyone has unique
tarrifs. You will be charged different rates at different times of
day, depending on how much power you've used in the last few hours, or
days. Readings are taken every few seconds and stored, then
transmitted back to the utility every few hours. Making comparisons
between suppliers will becoem impossible. (Not just rather difficult
as it is at present.)
