Cinergy has announced that they are moving forward with plans to develop and commercialize broadband over power wire service:
Cinergy Corp., owner of several Midwest utilities, and privately held Current Communications Group on Tuesday said they have formed two joint ventures to provide high-speed Internet service over electric power lines. …
Last week, the Federal Communications Commission proposed rules to foster growth in broadband over power lines, saying the service could increase the availability of broadband in rural and underserved areas due to the wide reach of the power grid.
Cinergy’s press release provides more details. They will start with data transmission and move toward VOIP service.
