Energy Insights – August 2022
Heating Season Peak Day Demand 2005-2022
The growth in peak demands shows that the US energy system continues to increasingly rely on the gas system to meet its needs, particularly during the coldest days of the year. A preliminary review of the data shows that customer and consumption growth across all sectors have likely contributed to growth in peak demand consumption.
Methodology
For purposes of this analysis, total domestic demand is measured as the sum of residential, commercial, and industrial demand; demand for power burn and LNG feedgas; net pipeline imports and exports; and pipe loss.
