Cost Optimization Strategies
The largest C&I savings on Evergy Missouri West come from managing billing demand and shifting load off-peak, since demand charges dominate Large General Service and Large Power Service bills.
Verify rate-class fit
For: All C&I classes
Confirm the account is on the lowest-cost eligible general-service class for its load factor and demand; misclassification is common after load changes.
Peak demand management
For: Large General Service, Large Power Service
Stagger equipment startup and shed non-critical load during peak intervals to lower billing demand (kW).
Off-peak load shifting (MOPS-1)
For: Large Power Service
Where eligible, use the Large Power Off-Peak Rider to move demand to off-peak periods.
Energy Analyzer monitoring
For: All C&I classes
Use Energy Analyzer hourly visualizations to identify usage spikes and baseload waste, informing efficiency projects and rebates.

Frequently Asked Questions
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.
