A power line communication (PLC) network includes a plurality of PLC devices. One such PLC device may include a transmitter power control system that determines a minimum level of transmission power for sufficiently communicating a plurality of data packets from the PLC device over the PLC network to a first destination PLC device on the PLC network by executing a training sequence over the PLC network via an electrical power distribution system. The transmitter power control system applies this minimum level of transmission power to transmit the data packets to the first destination PLC device.
