Quick question for the group - I have a client in Topeka considering primary service with Westar Energy (now Evergy). They currently have a 800kW peak demand on secondary service but want to install their own transformer to qualify for primary rates. Westar's Schedule MGS-P shows attractive savings, but their interconnection requirements seem pretty strict. Does anyone know if Westar has a minimum load threshold for primary service qualification? Their tariff mentions "adequate load levels" but doesn't specify numbers. Also wondering about their transformer specifications - do they require specific brands or just meet IEEE standards?
Westar (now Evergy) Primary Voltage Qualification Requirements
Floyd, I worked with Westar on a similar situation a few years back here in Kansas. They typically want to see consistent demand above 500kW to justify primary service, and your client at 800kW should qualify. The transformer specs need to meet IEEE standards but they don't mandate specific manufacturers. However, their protection coordination requirements are pretty detailed - you'll need to submit relay settings and fault study results as part of the interconnection application. The process usually takes 4-6 months, so factor that timing into your client's decision.
Thanks Rachel, that's helpful. The 500kW threshold makes sense and my client should be fine there. The 4-6 month timeline is longer than expected though. I'll need to factor that delay into the economic analysis since they won't see rate savings until the interconnection is complete. Appreciate the insight on the protection coordination requirements - sounds like we'll need a qualified electrical engineer involved from the start.
