Terms to Know

CCF:
Unit for measuring natural gas consumption. One CCF equals 100 cubic feet of natural gas.
HDD (Heating Degree Day):
HDDs are a weather-based calculation that compares the average of high and low temperatures each day (as reported by the National Weather Service) to the standard average daily temperature (65 degrees) when natural gas heating is typically used. HDDs adjust your bill to reflect typical weather, helping ensure costs are based on average weather conditions rather than unusual temperature swings.

How Your Natural Gas Bill Is Calculated

Delivery and Service Charges

Covers the cost of bringing natural gas to your home or business. These charges support Summit’s infrastructure maintenance, customer service, and commitment to providing safe, reliable service.

Supply Charges

The cost of natural gas is listed on your bill as the Commodity Charge. This covers what we pay our suppliers, plus delivery and adjustment costs.

Taxes and Other Charges

Includes any applicable local, city, county, and state taxes and charges.

How Natural Gas Prices Are Determined

The Commodity Charge is shaped by regional and national markets, and we pass it directly to you with no markup. We don't control the market price of natural gas. What we can do is work hard to secure the lowest possible rates for you. To keep things fair and fully transparent, we file all of these rates with our regulators for review.

Natural gas moves from the gas producer through Summit Utilities to your home, and Summit passes the cost through to you at the same price it pays
