Seasonal weather conditions have the most impact on the amount of natural gas you use. When it's cold outside, your furnace goes on more frequently and runs longer to warm your home. Your water heater also stays on longer to heat the colder incoming water.

Aside from weather-related and other changes in your gas appliance usage patterns, your bill may vary due to changes in wholesale natural gas prices, which change based on market conditions. The Natural Gas Company buys natural gas on the wholesale market for most residential and small commercial/industrial customers. We do not mark up this price, which is shown on your bill as as "The Gas Company's Gas Commodity."
