Frequently Asked Questions

What is Evergy's Large Load Service Rate Plan?

Large load customers under Evergy's approved service rate plan are billed under a dedicated large-load service rate plan and associated tariffs approved for Evergy, giving the utility a structured path to serve major new demand without shifting risk onto residential and small commercial customers.

Why did Evergy introduce this large-load structure?

To ensure the cost of new generation, transmission and distribution infrastructure built to serve very large customers, chiefly hyperscale data centres, is paid for by those customers rather than spread across the general rate base of residential and small commercial ratepayers.

What large data centre projects are already active in Kansas?

Evergy's Kansas City service territory carries some of the largest announced Midwest projects, including a $10 billion, 700 MW Google campus and a $4 billion Panasonic battery plant in De Soto.

Does this tariff replace Kansas's standard commercial and industrial rates?

No. Evergy's Large Load Service Rate Plan sits above Evergy's standard commercial and industrial rate schedules and applies specifically to customers that meet or exceed the large-load threshold described above. Smaller commercial and industrial loads continue to be billed under existing rate schedules.

How can I model a Kansas data centre build against this tariff and other states?

The SCR AI Build Configurator applies Kansas's power cost, tax treatment and large-load tariff rules alongside all other US states and Canadian provinces, so a Kansas scenario can be compared line-by-line against any alternative site.
