Abstract: A network communication device, such as an electricity meter, is configured to communicate with devices on a circuit internal to a site via power line communication (PLC), even when electricity service to the site is disconnected. The network communication device is configured to monitor one or more circuits internal to the site and to receive power line communications from the device(s) coupled to the circuit internal to the site when the site is disconnected from electricity service. A PLC module of the network communication device may include a switch-based or capacitor-based monitor that maintains a PLC coupler electrically connected with the circuit internal to the site even when electricity service to the site is disconnected.
