Since June 2015, Westar has not been adding new participants to the Westar Energy WattSaver program. For current program participants, Westar is continuing to provide replacement service only for the installed WattSaver thermostats at no cost. If it is found that your WattSaver thermostat needs to be replaced, WattSaver services include installing a replacement digital thermostat not part of the Westar Energy WattSaver program. Once a participant’s WattSaver is replaced with another thermostat, the customer is no longer eligible for WattSaver program services, and the thermostat will no longer participate in cycling events.
On the hottest weekday afternoons from June through September when many customers are using their air conditioners, demands on Westar Energy's system are the highest. At these times, we may cycle participants' central air conditioners or heat pumps in a coordinated effort to reduce energy demand.
