If I recall correctly, the connection was quick. However, it took a couple of months for them to start to account for it. (The application is reviewed and they have to accept you into the program after everything is in order.)
I had to call customer service to request to be changed to RT billing. That was a bit of a mess. I called...they said they would call me back in a week or so to "discuss it". When they didn't call back...I called them back and they said I was already scheduled that day to have the meter changed out.
Then they changed the meter...but they didn't change my rates to RT rates. I had to call them back again and finally get the rates changed.
For the meter and rates...try and get the department that installed new service or "upgrades" service...It's somewhere in the JCP&L phone menu / maze if I recall.
