Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing electric grid timing coordination. The method can include: receiving, by a first electric grid device, a message from a second electric grid device, the message including a first clock value associated with an oscillator of the second electric grid device; determining, based on the first clock value, a second-first device time offset between the second electric grid device and the first electric grid device; and storing the second-first device time offset in a time offset table stored at the first electric grid device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing an electric grid time synchronization process. The process can include: receiving, from a GPS transceiver of a first device coupled to an electric power grid, data including a GPS time reference; formatting the GPS time reference into a data packet, where the data packet has a particular format compatible with power line communication; and broadcasting, by the first device and using power line communications, the data packet to a plurality of electric grid components.
