GoodWattsâ„¢ interactive demand-side management service for the electric supply marketplace connects with homes through the same conduit used for cable TV services. The cable is connected to a modem, then to a wireless gateway device, which communicates with a special thermostat and other household equipment. Utilities can monitor energy usage in individual homes in real time, allowing energy usage curtailment in the event of high demand or emergency situations or shifting load to off-peak usage.
