When AEP burys the local lines in your neighborhood but leaves the feeder lines exposed, it's like being all dressed up with nowhere to go.
Drive down Lewis avenue south of 21st street and look at the feeder poles only inches from the road. Do cars hit those? Regularly.
And when they do, you can loose 10-15,000 customers at a time. Even people who have buried lines back in their neighborhood.
At best, AEP is cheap for not wanting to touch their record profits to maintain the infrastructure.
At worst, they might be found criminally negligent for operating a known, unreliable overhead distribution system in tornado alley/ice-storm central.
They can get on camera and say they are working every day to bury lines, but it is a minimal, uncommitted effort to appease ratepayers and the Corporation Commission. The work is overpriced, crawls at a snails pace and seems to be calculated to doing such a bad job that people will actually try to get them to halt undergrounding in their neighborhood.
When at&t came through burying their U-verse system, they dug a few small holes and tunneled between them. They were done in no time, and did the job in such a way that said "we want you to think well of this service so that you will want to be a customer". AEP has no such incentives and the job they do reflects that.
