Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for detecting a power outage. In one aspect, a status request requesting a status of a portion of a power distribution network is received, where the request includes a reference to a power meter that is located within the portion of the network. In response to the status request, a block of communications channels is selected, where the block includes a target communications channel over which a signal corresponding to the referenced power meter is received. In turn, an amplitude of the signal being received over the target communications channel is obtained. A determination is made whether the amplitude of the signal is less than an outage threshold and a status notification is provided that specifies the status of the portion of the power distribution network for which the status has been requested.
