Rate Recommendations by Use Case
Mid-size commercial facility (office, retail, light manufacturing)
Manage seasonal demand on MGS and evaluate the TOU variant for shiftable load.
MGS carries a steep summer demand charge ($7.961/kW vs $1.531 winter), so summer peak control and shifting load off the 3-7pm window deliver the most savings.
- Track summer peak demand closely
- Pre-cool or stagger HVAC before the 3-7pm on-peak window
- Model MGS-TOU vs standard MGS using interval data
- Request interval data from Evergy to support the analysis
Large commercial building with high steady demand
Optimize under LGS with attention to facilities and on-peak demand components.
At $18.643/kW, the LGS demand charge is the dominant cost; LGS-TOU separates on-peak and facilities demand, rewarding flatter, off-peak-weighted load.
- Benchmark via Account Link Advantage across buildings
- Target demand-limiting controls on the largest loads
- Evaluate LGS-TOU if load can shift off summer on-peak
Large industrial / manufacturing load
Take service under ILP, ideally at transmission voltage, and manage on-peak demand.
ILP energy rates are very low ($0.01433/kWh, lower at transmission voltage), so the per-kW demand charge and voltage level dominate total cost.
- Evaluate primary/transmission voltage service for lower demand and energy charges
- Confirm the 25,000 kW transmission billing-demand minimum applies to your load
- Use ILP-TOU to avoid the summer 3-7pm and winter 9am-9pm on-peak demand windows
- Consider Business Demand Response for additional incentive revenue
Multi-site / portfolio energy manager
Aggregate accounts via ALA and request data exports for portfolio analysis.
With no Green Button or API, ALA plus custom data exports are the practical path to portfolio-wide visibility for benchmarking and verification.
- Enroll buildings in Account Link Advantage
- Submit a custom data request for machine-readable usage
- Use BEAT for benchmarking and ordinance compliance

October 1, 2025
Docket 25-EKCE-294-RTS settlement: approximately $196 million revenue increase (~8.6%) for Evergy Kansas Central, with a 9.7% ROE for transmission delivery charges. New tariff sheets effective October 1, 2025.
+8.6%December 21, 2023
Prior Kansas Central tariff revision (effective December 21, 2023) preceding the 2025 rate case.
n/aOverall trend: Rising. Successive rate cases have increased base revenue requirements, driven by infrastructure and transmission investment.
Next expected change: Future base rate case expected within the next 1-3 years; transmission delivery charge and tariff riders may adjust sooner.
Cost Optimization Strategies
Because demand charges dominate C&I bills on MGS, LGS, and ILP, the highest-impact strategies focus on reducing and shifting peak demand and, where eligible, taking service at higher voltage.
Peak demand management
For: MGS, LGS, ILP
Stagger equipment startups, use load controls, and flatten demand peaks to lower the per-kW demand charge that drives MGS/LGS/ILP bills.
Time-of-use rate adoption
For: MGS-TOU, LGS-TOU, ILP-TOU
Shift shiftable load out of the summer 3-7pm on-peak window onto TOU variants (MGS-TOU, LGS-TOU, ILP-TOU) to capture lower off-peak and super-off-peak energy pricing.
Service voltage optimization
For: ILP
Large industrial loads taking service at primary/transmission voltage receive lower demand and energy charges under ILP (e.g., $13.042/kW transmission vs $17.188/kW).
Business Demand Response participation
For: MGS, LGS, ILP
Enroll in Evergy's Business Demand Response to earn incentive payments for reducing load during peak events.

Frequently Asked Questions
Can a C&I customer get 15-minute interval data from Evergy Kansas South?▾
Not through a standard self-service channel. Although Landis+Gyr AMI is deployed and capable of interval reads, Evergy exposes only monthly usage through the My Account portal. Interval data must be requested directly from customer service (800-383-1183), and availability, format, and fees are handled case-by-case.
Does Evergy support Green Button or an API for automated data access?▾
No. Evergy Kansas does not implement Green Button Download My Data, Connect My Data, or ESPI, and offers no official customer data API. An unofficial community Python library exists but is unmaintained and not recommended for business use. Automated access generally requires a custom data export arrangement.
How does a consultant or aggregator access a client's Evergy data?▾
Obtain signed written authorization from the customer specifying data types and time period, then submit it with the account number to Evergy customer service. Evergy can create a third-party login, enroll the customer in Account Link Advantage for multi-meter aggregation, or deliver a data export, typically within 5-10 business days.
What rate schedules apply to commercial and industrial customers?▾
C&I customers are served under Evergy Kansas Central tariffs approved by the KCC: Small General Service (SGS), Medium General Service (MGS), Large General Service (LGS), and Industrial & Large Power Service (ILP), each with time-of-use variants. Larger schedules carry significant demand charges per kW of billing demand. See the rate section below for current figures.
Can I aggregate usage across multiple buildings or meters?▾
Yes. Account Link Advantage (ALA) lets building owners and authorized third parties aggregate billing and usage across multiple meters, which also powers the Building Energy Aggregation Tool (BEAT) for benchmarking and ordinance compliance.
