Why did Evergy / Ameren Missouri introduce this large-load structure?

Ameren Missouri is serving a $15 billion Google data center project in New Florence, with Google contracting to bring more than 1,000 MW of new generation to the state and working with Ameren on an additional 500 MW.

No. Evergy's Special High Load Factor Market Rate and Large Load Power Service sits above Evergy / Ameren Missouri'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 Missouri data center build against this tariff and other states?

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