Two Texas companies - Current Communications Group and TXU Electric Delivery -plan to offer high-speed internet service over the power grid, reports CNET. Some two million homes and businesses in northern Texas would be able to subscribe to the new service after the network is completed. Current Communications has built a similar network over Cincinnati's power lines and will design, build and operate the new broadband network.

Current said the network would have enough capacity to offer customers telephony, TV service and high-speed internet access. Users would gain access by plugging a device into an electrical outlet.

The broadband network will be laid on top of the existing power infrastructure, and TXU will then lease this infrastructure to broadband providers such as Current.
