Rate Schedules & Tariff Analysis
Peoples Gas C&I bills separate regulated delivery charges from the gas commodity. Delivery is dominated by a fixed customer charge (scaling with meter class) plus volumetric distribution; the gas charge is a monthly pass-through for sales customers and competitive for Choices for You transportation customers. Rate 4 adds a meaningful demand charge ($1.40678/therm of peak winter daily demand), making winter load management material for large users. A January 2026 ICC rate case (~$202.3M revenue request) may raise delivery charges once approved.
The Peoples Gas Light and Coke Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate 2 - General Service | Commercial/industrial up to ~41,000 therms/month |
| Rate 4 - Large Volume Demand Service | Large industrial above ~41,000 therms/month |
| Rate 8 - Compressed Natural Gas | CNG operations |
| Rider CFY - Choices for You | Competitive gas supply for Rate 1/2/8 customers |

The Peoples Gas Light and Coke Company Data Access FAQ
Can my business get interval (hourly or daily) gas data from Peoples Gas?▾
Not for standard accounts. The highest granularity for most commercial and industrial customers is monthly therm usage in My Account. Transportation-service customers under the Choices for You program receive daily delivery-range data through the PEGASys system, which is the closest thing to interval data Peoples Gas offers.
Does Peoples Gas support Green Button or an API for our energy software?▾
Peoples Gas does not offer Green Button (ESPI) downloads or a public REST/SOAP API of its own. Programmatic exchange through the utility is limited to certified Choices for You suppliers via custom FTP and the PEGASys web system. Nectar provides API access to this utility's billing data — see docs.nectarclimate.com.
How does a consultant or broker get authorized to pull our usage data?▾
The customer signs a Third-Party Verification Agreement naming the agent and the authorized data types, then submits it to eis@peoplesgasdelivery.com (or by mail to 200 E. Randolph St., Chicago, IL 60601). Once recorded, the agent can request billing and usage history, typically within 3-5 business days. Peoples Gas may charge a processing fee.
Which rate applies to a commercial or industrial gas account?▾
Rate 2 (General Service) covers multi-family, commercial, and industrial customers averaging 41,000 therms/month or less. Rate 4 (Large Volume Demand Service) applies above that threshold and adds a billing-demand charge. Rate 8 covers compressed natural gas. All include a fixed customer charge, volumetric distribution charge, storage charge, and a pass-through gas charge for sales customers.
Can a C&I customer shop for a competitive gas supplier?▾
Yes. Under Choices for You (Rider CFY), customers on Rates 1, 2, and 8 can buy the gas commodity from an ICC-licensed alternative supplier while Peoples Gas continues to deliver. Delivery (distribution) charges stay regulated; only the gas commodity portion becomes competitive. Customers have a 10-business-day rescission window on supplier contracts.
