Rate Schedules & Tariff Analysis
Consumers Energy C&I electric rates are demand-driven for all but the smallest accounts. The choice between GS, GSD, GP/GPD and TOU hinges on load factor, peak behavior and service voltage. Taking service at primary voltage (GP/GPD) earns a voltage credit but requires customer-owned transformation. Demand charges are set on the maximum 15-minute interval each month, making peak management the largest lever on cost.
Consumers Energy Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| GS / GSD (Secondary) | Commercial customers at secondary voltage; demand charge applies above GS |
| GP / GPD (Primary) | Large C&I at primary voltage with demand charges and voltage credit |
| GS Gas (GS-1/GS-2) | Firm commercial/industrial gas distribution, tiered by usage |
Consumers Energy Company Rate Features & TOU Details
- Demand charges based on highest 15-minute monthly peak (GSD/GP/GPD)
- Primary-voltage schedules (GP/GPD) offer voltage credits for customer-owned transformation
- Time-of-Use option rewards off-peak/night/weekend operation
- Power Supply Cost Recovery (PSCR) factor passes through fuel/power costs on electric bills
- Gas C&I service is firm distribution tiered by annual Mcf with separate Gas Cost Recovery (GCR)

- ⚠Energy Bridge device availability is a limited pilot.
- ⚠Third parties may retain data already downloaded after a customer revokes access.
Consumers Energy Company Data Access FAQ
How do C&I customers get interval data from Consumers Energy?▾
AMI-metered electric customers can view hourly interval data next-day in the Energy Dashboard and download it as Green Button ESPI XML, or authorize a vendor through Green Button Connect My Data (UtilityAPI, OAuth 2.0) for automated JSON/ESPI feeds. Gas is monthly.
Does Consumers Energy have a data API for vendors?▾
Yes. Through Green Button Connect My Data on UtilityAPI, approved third parties access a JSON API and a Green Button (ESPI) REST API using OAuth 2.0 after registering, testing in sandbox, and receiving Live Mode approval (5-10 business days).
Can we choose our electricity supplier in Michigan?▾
Only partially. Michigan electric Customer Choice is capped at 10% of a utility's prior-year load and is often waitlisted, so most Consumers Energy customers take bundled service. Gas Customer Choice is more broadly available.
What drives a large commercial electric bill on Consumers Energy?▾
Demand charges (kW) on primary/large C&I schedules are typically the largest component. Hourly interval data analysis to flatten peaks, plus Peak Time Rewards / Critical Peak Pricing participation, are the highest-impact levers.
Is Consumers Energy's Green Button standardized?▾
Yes. Its Green Button Connect My Data platform is certified compliant with NAESB REQ.21 ESPI v3.3 (Sept 2022) and DOE DataGuard, providing standardized ESPI XML and JSON access.
