Rate Schedules & Tariff Analysis

C&I customers should match their load profile to the correct general-service class and evaluate demand-management opportunities. Because demand charges drive a large share of Large General Service and Large Power Service bills, peak-shaving and load-factor improvement typically yield the greatest savings. All schedules pass through fuel costs via the Fuel Adjustment Clause.

Evergy Missouri West Rate Schedule List

ScheduleApplicability
Small General ServiceSmall commercial below the Large General Service demand threshold
Large General ServiceMid-size commercial with measured demand
Large Power ServiceLarge commercial and industrial high-demand customers

Evergy Missouri West Rate Features & TOU Details

  • Customer charge + energy charge for small commercial
  • Per-kW demand charges for Large General Service and Large Power Service
  • Fuel Adjustment Clause (Schedule FAC) applies to all schedules
  • Large Power Off-Peak Rider (MOPS-1) for shifting demand off-peak
  • Schedule LLPS for new loads over 100 MW

Evergy Missouri West Data Access FAQ

Does Evergy Missouri West offer an API or Green Button for C&I usage data?

No. Evergy Missouri West does not offer Green Button (Download or Connect My Data), a public API, or a developer portal. Commercial customers and their consultants access data through the My Account portal, the Energy Analyzer tool, or Account Link Advantage, all of which are manual and web-based.

How can an energy consultant access a commercial customer's usage data?

Two routes exist: (1) the customer adds the consultant as an authorized user on Account Link Advantage to view designated accounts in the portal, or (2) the customer signs an authorization letter and the consultant requests a custom data extract from businessrebates@evergy.com (866-503-9092), typically a 2-4 week turnaround.

Can I download interval (15-minute or hourly) data for a commercial site?

Not directly. Interval data is collected by the Landis+Gyr AMI meters and stored in Evergy's MDM, but customers can only view hourly usage as charts in the Energy Analyzer. There is no raw interval file export; custom extracts must be negotiated with business support.

Is EDI billing available for commercial accounts?

No. Evergy uses EDI/ANSI X12 only for supplier and vendor payments, not for customer billing or usage data. There is no EDI trading-partner program for customer data; web-based methods are the only option.

How can I aggregate usage across a multi-tenant building in Kansas City?

Use the Building Energy Aggregation Tool (BEAT), available only within Kansas City. The building owner collects tenant authorizations and submits an Account Aggregation Request Form to receive anonymized whole-building usage suitable for ordinance benchmarking.
