Energy Insights: Normalized Natural Gas Use per Residential Gas Customer
- Normalized natural gas use per residential gas customer fell 48% between 1971 and 2021, or 1.29% per year for 51 years.
- Since the significant winter heating season in 2014, use per customer has declined at a faster rate than the decade average (0.63% versus 0.48%). 2021 alone declined by 0.83%. In prior decades, most years showed a decline:
- Annual rate of decline, 1970-1979 = 1.06%
- Annual rate of decline, 1980-1989 = 1.26%
- Annual rate of decline, 1990-1999 = 0.89%
- Annual rate of decline, 2000-2009 = 1.51%
- Annual rate of decline, 2010-2020 = 0.48%
- Annual rate of decline, 2014-2020 = 0.63%
- Annual rate of decline, 2020-2021 = 0.83%
- Non-weather-dependent appliances such as cooking stoves, water heaters, and dryers have seen significant reductions in average consumption of natural gas per customer. Non-weather-dependent use of natural gas per customer has declined at an average annual rate of 1.82% since 1971.
- Based on the 2021 U.S. Census Bureau American Housing Survey, the average gas household uses two to three natural gas appliances.
Supplemental Materials from AGA’s Normalized Use per Customer Model
- Non-weather-dependent appliance volumes are assumed to match the average consumption during July and August, with the excess consumption in other months assumed to be weather-sensitive.
- Weather-sensitive heating demand is normalized by multiplying load by the ratio of 30-year normal heating degree days over actual annual calendar heating degree days.
