As of June 12, 2015, Westar will no longer be adding new participants to the WattSaver program. That is, we will no longer be making appointments with Westar Energy customers to install WattSaver thermostats. For current WattSaver program participants, we will continue to service WattSaver thermostats. However, if it is found that your WattSaver thermostat needs repair, Westar will have it replaced with a different digital thermostat that will not cycle as part of Westar’s WattSaver program.
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.
