Answer 1

Duke Power, along with Progress Energy in Raleigh, N.C, and Consolidated Edison in New York, is one of three power companies currently in trials with EarthLink.

Duke began its trial with 500 homes and plans to launch a commercial service to 10,000 to 15,000 homes by the end of this year, said Gerardi. The company, which will rent access to its network to ISPs such as EarthLink, said it will be able to handle high-speed data services at 512kbps to 5mbps, along with voice over IP services. The cost of the service will likely be about $30 a month.
