First Energy Corp is also working on building a network like that. It's being test piloted in many markets- Toledo and Cleveland being two of them in Ohio. Dominion has smart meters for gas and electric. Although with gas they drive down the street and the trucks just download the meters readings.- Columbia Gas and NiSource did the same thing. Many water companies and city departments are deploying wireless smart meters as well.
Yea Columbia Gas just converted us to that system, I think AEP sorta encouraged them to since they was first, but like you said I thing the gas system is read by drive by. Waiting to see if the city is going to do this with water, though I think the loss of jobs pushback will kill it, as i'm shire AEP and columbia were doing it for that and not the outer benefit they trumpet. Which is bad for the economy but well was gonna happen sooner or later.
