This report details findings from a pilot High Voltage Broadband over Power Line (HV-BPL) program, an effort to develop a disruptive technology that can not only replace the pilot wire relaying systems used to protect some high voltage transmission lines but can also provide a secured broadband communication path for other services. HV-BPL can provide a secure, low-cost alternative to the conventional, expensive and time-consuming option of deploying optical fiber communications systems along transmission lines, according to the authors.
