Station to Station Communications over Electric Utility Transmission Lines

With support from host utility American Electric Power (AEP) (NYSE:AEP) and the US Department of Energy (DOE),

The research and development project was begun in November 2007 under the auspices of the Electrical Grid Transformation Program, with oversight by the DOE's National Energy Technology Laboratory (NETL). Research and Development Solutions (RDS) was selected to manage the project on behalf of DOE/NETL. The focus was the implementation of broadband over power line (BPL) technology to provide data communications capable of supporting a wide range of Smart Grid applications. Equipment vendors ABB (www.abb.com) and Cooper Power Systems (www.cooperpowersystems.com) provided some of the materials for this project. Amperion developed a number of unique signal coupling and modulation techniques during the multi-month trial period.
