Duke Energy is testing a "smart grid" application designed by Cisco Systems for household use.
Cisco's Home Energy Management Solution features a countertop display that gives consumers real-time data, past energy readouts and usage levels of individual appliances.
About 100 Duke Energy customers are testing the system, but Duke wants to extend the tests for another year.
Duke, based in Charlotte, is the state's biggest electric utility. Cisco, the computer networking giant based in California, employs 4,500 at its office complex in Research Triangle Park. The company is making a major push into Smart Grid technology, much of which would run over Cisco's networks.
