Nicor Gas applies a Storage Loss Gas Adjustment (SLGA) percentage to gas received from Hub customers for injection into storage under Rate 21, Intrastate Transportation and Storage Services, which reduces the amount of gas credited to a customer’s storage account. According to the Rate 21 tariff, the SLGA percentage is determined annually.

Nicor Gas has completed its annual assessment of the SLGA, setting the percentage at 0.00%. This SLGA will be applied to storage and imbalance resolution transactions for new Rate 21 agreements entered into on or after September 1, 2024.

For Hub customers contracting for storage services under Nicor Gas' Operating Statement filed with the Federal Energy Regulatory Commission (FERC), the current SLGA is 0.40%, and the Fuel rate is 0.18%.

Hub Contract Forms
To engage in business at the Chicago Hub®, shippers must enter into either interstate or intrastate Hub Service Agreements with Nicor Gas, depending on the services they wish to acquire. Those seeking intrastate services must also sign an affidavit confirming that all gas provided under the intrastate Hub Service Agreement will be used within the State of Illinois. Once the necessary Hub Service Agreements are made, Nicor Gas Hub Administration can provide specific services, which are detailed and agreed upon in individual Transaction Request and Agreement forms. Blank samples of these documents are available upon request.
