One interesting point - they plan to use Broadband over Power Line

one of the top costs and trickiest problems for utilities.

Dan,
there's one very big assumption in your statement: cost of BPL for metering is
economical or workable in the regulatory model. Forget value added services
for a moment, the cost often cannot be burdened on the rate payer (regulatory
constraint). So, funding this sort of effort is

Especially in rural areas (where physically reading meters sucks the most due
to long inter-house distances), you have no guarantee of good cellular coverage.
The electric company *can* however assume they have copper connectivity to
the meter by definition
Doesn't have to be copper- it
Why is IP required, and even if you used IP for transport why must the
meter identification be based on an IP address? If meters only report
information, they don't need a unique transport address and could put
the meter identifier in the application data.
Even if the intent is to include
Virginia Power replaced our meter over the summer with a new one that
has wireless on it. The meter reader just drives a truck past the
houses and grabs the data without him/her ever leaving the truck. I
have no idea what protocol they're using, or if it's even remotely
secure.
