SUBURBAN NATURAL GAS COMPANY NOTICE OF APPLICATION

SUBURBAN NATURAL GAS COMPANY NOTICE OF APPLICATION FOR AN INCREASE IN RATES AND CHARGES BEFORE THE PUBLIC UTILITIES COMMISSION OF OHIO Public notice is hereby given that Suburban Natural Gas Company filed an Application on June 16, 2025 with the Public Utilities Commission of Ohio (PUCO) requesting an increase in rates and charges for natural gas distribution service rendered in its service territory. The case number of the proceeding, In the Matter of the Application of Suburban Natural Gas Company for an Increase in Gas Distribution Rates before the PUCO is 25-0553-GA-AIR. Four related cases, In the Matter of the Application of Suburban Natural Gas Company for Tariff Approval, In the Matter of the Application of Suburban Natural Gas Company for Approval of Certain Accounting Authority, In the Matter of the Application of Suburban Natural Gas Company for Approval of an Alternative Form of Regulation, and In the Matter of the Application of Suburban Natural Gas Company for Approval to Establish an Infrastructure Development Rider, can be found at PUCO Case Nos 25-0554-GA-ATA, 25-0555-GA-AAM, 25-0556-GA-ALT, and 25-0557-GA-IDR, respectively. Suburban Natural Gas Company last increased in rates and charges in 2019. Suburban Natural Gas Company's operating costs have increased substantially since 2019, and its net income is no longer sufficient to earn an adequate return on the Company's property dedicated to service. The proposed rates reflect the investment needed to continue to provide safe and reliable natural gas distribution service to the customers of Suburban Natural Gas Company at just and reasonable prices. This proposed rate increase does not affect any special atrangements that have been approved by the PUCO. Suburban Natural Gas Company has proposed this rate change based on the costs it would incur during a test year of October 1, 2024 to September 30, 2025, and the value of gas distribution plant as of December 31, 2024. The Application seeks an increase in the monthly customer service charge of $6.97 for small general service customers (which includes residential customers) above the monthly customer service charge approved by PUCO and in effect when the proposed rates would become effective. Under the new rates, there will be no charge based on usage for small general service customers. For a customer consuming 12 Mof per month the percentage increase in the customer's total monthly bill would be 5.55%. Recommendations which differ from the Application may be made by the Staff of the PUCO or by intervening parties and may be adopted by the PUCO. August 6, 13 '25
