See the North Shore Gas Company Rate Schedules & Tariff Guide →Interval Data & Smart Meters
North Shore Gas has deployed AMI (Automated Meter Reading via the Itron network shared with ComEd, ICC-approved October 2022) but does not expose customer-facing interval data. Residential and small commercial customers see monthly therm usage only. Transportation customers can access daily/monthly operational data through the Energy Information System (EIS) and PEGASys.

Interval data is essential for rate comparison and TOU analysis.

North Shore Gas does not offer a public RESTful API, developer portal, ESPI, or OAuth. Programmatic access is limited to suppliers and transportation customers through the Energy Information System (EIS) web portal, the PEGASys gas-transportation management system, and the proprietary Choices For You Data Exchange Mechanism file-transfer process. Consultants/aggregators must use a Third-Party Verification Agreement.

EDI (Electronic Data Interchange)
North Shore Gas does not support standard ANSI X12 or EDIFACT EDI for general use. For the Choices For You program, suppliers exchange data through a proprietary Data Exchange Mechanism File Transfer Process rather than industry-standard EDI. Supplier enrollment requires ICC certification and a Gas Transportation contract.

Rate Schedules & Tariff Analysis
North Shore Gas C&I rates split into regulated delivery (ICC-set: customer charge + volumetric distribution + storage, plus a demand charge for Rate 4) and a pass-through Gas Charge for the commodity. Rate 2 serves customers averaging 41,000 therms/month or less; Rate 4 applies above that and adds a demand charge of $0.75527 per therm of Billing Demand, set by peak winter (Dec/Jan/Feb) daily demand. Because supply is deregulated via Choices For You, commodity procurement is a key cost lever; the demand charge is the dominant delivery cost for large, peaky loads.
North Shore Gas Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate 2 – General Service | ≤41,000 therms/month; customer charge varies by meter class |
| Rate 4 – Large Volume Demand Service | >41,000 therms/month; demand-based |
| Rate 5 – Electric Generation | Gas-fired generation >25 MW (contract) |

North Shore Gas Company Data Access FAQ
Can my business choose its own natural gas supplier from North Shore Gas?▾
Yes. Through the Choices For You program, business customers under Rates 1 and 2 can buy the gas commodity from an ICC-certified alternative supplier. North Shore Gas still delivers the gas, reads the meter, and sends the bill — only the Gas Charge changes. Customers who do not shop pay the pass-through Gas Charge with no utility markup.
How is the Rate 4 demand charge calculated?▾
Rate 4 (Large Volume Demand Service, for customers averaging more than 41,000 therms/month) carries a demand charge of $0.75527 per therm of Billing Demand. Billing Demand is your highest daily demand during the peak months of December, January and February over the most recent 12-month period — so reducing winter peak usage lowers the charge for a full year.
How does a consultant or aggregator get my North Shore Gas usage data?▾
There is no public API or Green Button. The customer signs a Third-Party Verification Agreement authorizing release, then the third party requests historical usage (up to 24 months, typically monthly) via eis@northshoregasdelivery.com or 800-264-8026. Response time is usually 1-2 business days, and charges may apply for detailed requests.
Does North Shore Gas offer interval data or Green Button?▾
No. Despite AMI deployment (the Itron network shared with ComEd, approved in 2022), North Shore Gas does not offer Green Button, Connect My Data, ESPI, or customer-facing 15/30-minute interval data. Most customers see monthly therm usage; transportation customers can access daily/monthly operational data via EIS and PEGASys.
What does the current Gas Charge cost, and does it change?▾
The Gas Charge is a monthly pass-through of North Shore Gas's actual cost of gas, with no utility markup. It was $0.4237/therm for June 2026, down from $0.5053/therm in May 2026 and $0.5298/therm in June 2025. Delivery and demand charges are separate and set by the ICC tariff.
