A heating degree day (HDD) is a measure of how cold a location is. It’s derived by comparing the average outdoor temperature to a baseline of 65 degrees. More extreme cold temperatures result in a higher number of HDDs, which typically translate to an increased demand for space heating by energy consumers.
NPGA has now produced data sets that detail the number of HDDs that occurred during each month of the heating season (October-March) over the past 3 years, as well as each month’s 10-year average, broken down by Census Division. As members continue to evaluate their potential supply and demand scenarios for the upcoming heating season, they can use these data to better understand what the needs of their customers were in previous years.
These data sets can be found under the Supply and Logistics section on the Member Dashboard of NPGA’s website. For more information, please contact NPGA’s Jacob Peterson.
