Rate Recommendations by Use Case
Mid-size commercial facility (25–750 kW)
Large General Service is mandatory above 25 kW summer demand. Focus on demand management to control the seasonal ratchet.
Summer demand at $17.26/kW plus a 75% ratchet dominates the bill; energy is comparatively cheap at 5.81¢/kWh summer.
- Track 30-minute peak demand and trim summer peaks
- Pre-cool or shift load away from afternoon peaks
- Model the ratchet impact before adding summer load
Large industrial load (>750 kW)
Industrial Service applies automatically above 750 kW. Pursue primary service and power-factor compliance for the lowest effective rate.
Lowest energy rate (5.19¢/kWh summer) but a high fixed demand block ($18,841.95 for first 750 kW summer); discounts reward owning primary equipment.
- Maintain ≥90% power factor to avoid demand penalties
- Evaluate 13,800V+ primary service for the $0.10/kW credit
- Use the load-shedding program for additional demand credits
Small business / office (<25 kW)
Stay on the energy-only Small General Service rate and avoid optional demand billing unless usage is very flat.
Below 25 kW there is no demand charge on the standard rate; the optional demand rate only helps high-load-factor sites.
- Monitor summer demand to stay under 25 kW
- Compare standard vs optional demand rate annually
- Register for MyMeter to track monthly usage
Data access for energy management
With no AMI or API today, plan for monthly data and manual collection. Use MyMeter exports or a Sunshine Law request to assemble history.
No interval data, Green Button, or API exists; AMI is planned but unscheduled.
- Pull monthly usage from MyMeter for trend analysis
- File a Sunshine Law request for formal historical data
- Track AMI rollout for future interval-data access
Historical Rate Trends
Rates are revised through the City's annual budget ordinance. The most recent change was a 2% across-the-board increase effective October 1, 2025.
October 1, 2025
2% increase to the customer charge and per-kWh energy rates across electric schedules, adopted in the FY2026 budget (Ordinance Chapter 27, Sec. 27-112).
+2%Overall trend: Gradual annual increases driven by cost-of-service and power supply costs.
Next expected change: Next change expected with the FY2027 budget cycle (effective ~October 2026).
Cost Optimization Strategies
Because Columbia's C&I rates are heavily demand- and season-driven, the biggest savings levers are managing summer peak demand and the resulting ratchet.
Manage the summer demand ratchet
For: Large General & Industrial customers
Shave summer (June–September) peak kW, since 75% of the summer peak sets a billing-demand floor for the next 11 months.
Stay below the 25 kW threshold where viable
For: Small commercial
Small commercial loads kept under 25 kW summer demand remain on the simpler Small General Service energy-only rate and avoid demand charges.
Take primary service / primary metering
For: Industrial (>750 kW)
Industrial customers owning equipment at 13,800V+ earn a $0.10 × peak-kW credit; primary metering reduces measured demand and kWh by 2%.
Participate in load shedding / energy storage rider
For: Large General & Industrial
Large general service customers can earn a $3.00/kW-shed performance credit, and an energy-storage rider offers off-peak energy at 4.592¢ (summer)/4.00¢ (non-summer).

Frequently Asked Questions
Can a C&I customer get interval (15-minute) data from Columbia Water & Light?▾
Not today. The utility runs an AMR system that captures only monthly reads. Sub-monthly interval data will not be available until the planned AMI deployment goes live, which has no confirmed date as of 2026.
Does Columbia Water & Light support Green Button or a third-party data API?▾
No. There is no Green Button Download/Connect My Data, no ESPI API, and no public developer portal. Third-party access is limited to customer-mediated portal sharing or a fee-based Sunshine Law records request.
How can an energy consultant obtain a commercial customer's usage history?▾
Either the customer shares MyMeter screenshots/exports, or you file a Missouri Sunshine Law request at the City's NextRequest portal with the customer's account number. Sunshine Law requests are fee-based and typically answered within three business days.
Is there EDI (814/867) support for C&I billing?▾
No EDI program is publicly documented. Businesses needing EDI should contact Utility Customer Service to ask whether transactions can be configured on the CIS Infinity billing system.
What commercial rate will my facility be on?▾
Small commercial loads under 25 kW use the Small General Service rate; loads exceeding 25 kW in summer move to Large General Service; and loads exceeding 750 kW in summer are placed on the Industrial Service Rate. All schedules carry a Power Cost Adjustment rider.
