While producing electricity with solar panels and small scale-wind turbines is still a more expensive option than purchasing electricity from us, customers are increasingly showing an interest in powering their homes and businesses with self-generating systems.
Is self-generation right for you? The PVWatts calculator can help you learn more.
There is also a very helpful guide to rooftop solar by Louisiana State University, Solar Power for Your Home, A Consumer's Guide.
Beginning NOVEMBER 1, 2016 a production meter (a meter to record customer generation) will be required for all new interconnection application approvals. This design is becoming an industry standard, is generally accepted as a best practice for customer owned generation installations, and is needed to analyze distribution loads. The information from these meters will better enable us to accommodate higher penetrations of distributed energy resources, by providing important circuit load information.
Beginning JANUARY 1, 2017 a production meter will be required for ALL physical connections regardless of application date. This includes the interconnections approved without a production meter prior to November 1st.
For questions regarding this notice, please contact Westar’s interconnection service advisor at 316-299-7426.
Westar Energy offers Net Metering service for customer-owned renewable energy generation installations. Net metering was made possible with the passage of the Easy Connection and Net Metering Act by the Kansas Legislature in 2009 and by utilities and the Kansas Corporation Commission (KCC) working to implement this Act.
Westar's Net Metering service provides for the electrical energy produced by your renewable generating resource to offset the energy we provide during the billing period. For example, if the excess electricity we supply you exceeds the electricity generated by your renewable generating system during a billing period, you will be billed for that net electricity. If the excess electricity generated by your renewable generating system exceeds the electricity we supply you during a billing period, you will be credited for the excess kilowatt-hours with such credit to be applied during that billing period. Customers who installed renewable systems prior to July 1, 2014, remain on the prior net metering agreement, and such credits carry over to subsequent billing periods, with excess credits expiring at the end of each year. Customers who install a renewable energy system after July 1, 2014, are credited for excess generation at the retail rate within the month, and they are paid Westar's avoided cost for any excess generation at the end of each month.
Net Metering Rider
Westar pays you 150 percent of its monthly average energy costs for energy you put back on the grid.
Westar operates its power plants using a variety of fuel sources (nuclear, coal, gas, oil, wind, purchased power, etc.) The monthly average fuel cost is what we spend on fuel, on average, for a particular month to run our mix of power plants.
Any energy (kWh's) fed back into Westar's system from self-generation is power that Westar does not have to produce, and therefore, fuel we don't have to purchase. This is how we determine "avoided cost," and compensate self-generators accordingly.

The Westar Energy Facility Connection Standard lists the system design requirements for connecting renewable energy systems to the electric grid. Generating systems must also meet our Service Standards. In order to successfully interconnect your system, you must complete the Interconnection application (link above).
