National Fuel Requests Base Delivery Rate Increase for Pennsylvania Customers

Today, National Fuel Gas Distribution Corporation (National Fuel) filed a request with the Pennsylvania Public Utility Commission (PUC) to increase annual base delivery rate revenues for Pennsylvania customers by $19.7 million, or 7.4% of total revenues. To help offset the impact of the proposed revenue increase on customers, the filing also seeks to return $7.2 million that was previously collected but is no longer needed for retiree health benefits. If approved, the monthly bill for an average residential customer using 80 hundred cubic feet of natural gas per year would increase by $4.95, or 5.9%. This is the Company's first rate increase request since 2022, and only its third requested increase in the last 20 years.

An increase in delivery rates, which cover the costs of operating National Fuel's utility distribution system, must be approved by the PUC after a formal regulatory review. If approved, new delivery rates would likely take effect on Nov. 1, 2026.

In northwest Pennsylvania, National Fuel operates 4,850 miles of pipelines and related facilities, has more than 435 employees and delivers natural gas safely and reliably to approximately 214,000 residential, commercial and industrial customers. Rising operating costs and the need to continue investing in the modernization and safety of National Fuel's distribution system have resulted in conditions where an increase in base delivery rates is necessary. National Fuel's proposal would support its ability to:

• Accelerate pipeline replacement and modernization to improve safety, reliability and efficiency.
• Address inflationary pressures on operating costs for labor and benefits, material and service purchases and technology and cybersecurity upgrades.
• Launch a new Energy Efficiency pilot program for residential customers that will offer rebates to those who install high-efficiency natural gas appliances. The pilot is designed to help customers reduce energy usage and lower long-term bills.

"Our customers expect a safe, reliable energy system and these investments help ensure we continue to meet that expectation," said Michael Colpoys, president of National Fuel Gas Distribution Corporation. "Affordability also is a top priority. Even with the proposed adjustment, National Fuel will continue to have the lowest delivery rates in the state, and our customers will continue to benefit from the abundant and highly affordable natural gas supplies produced here in Pennsylvania."

The Pennsylvania PUC Rate Comparison Report, issued in April 2025, shows that National Fuel has the lowest total monthly bills and the lowest customer and distribution charges among large gas utilities in Pennsylvania.

National Fuel's proposal will undergo a thorough review by the PUC, a process that typically lasts up to nine months. As part of this review, the PUC may accept, reject or modify the filing. Customers who want to understand specific rate classes or how the filing may affect their bills should contact National Fuel at 1-800-365-3234.

This request for delivery-rates changes is separate from the quarterly adjustments National Fuel makes to gas supply charges, which reflect the market costs of natural gas purchased for customers. Gas supply costs are passed through to customers dollar for dollar with no markup or profit to National Fuel. The next opportunity to adjust gas supply charges will be Feb. 1, 2026.
