What factors influence natural gas use?

Several factors can influence your monthly natural gas use. These factors can be measured by WPS, and we summarize them on your monthly bill.

Billing days
WPS makes every effort to read your meter once a month. The number of days between the monthly meter readings may vary slightly — it won't be exactly 30 or 31 days each time. Your bill shows the number of billing days included and how that compares with the same month last year.
Average daily temperature
Weather can play a significant role in how much natural gas you use. During a cold winter when more heating is required, your use is typically higher. During a mild winter, your use may be down. The average daily temperature shown on your bill compares this month with the same month last year.
Cooling degree days
A measure of the need for air conditioning (cooling) based on temperature. Cooling degree days are calculated by subtracting 65 degrees Fahrenheit from the average daily temperature.
Heating degree days
A measure of the need for heating based on temperature. Heating degree days are calculated by subtracting the average daily temperature from 65 degrees Fahrenheit.
Percent warmer or cooler
Your bill shows what percent warmer or cooler it was this month compared with the same month last year. This percentage is calculated based on the number of degree days this year compared with last year.
Therms used and average therms/day
Therms are a measure of the heat content of the gas you use. Your bill shows how many therms were used this year compared with last year — and the average number of therms used each day.
