Consumption vs. degree days, by month
energy vs. °F·daysEach point is one month: average consumption per account against that month's heating + cooling degree days. A steeper rise means more weather-sensitive load.
The model
E = 1353 + 4.1457·HDD
- Heating slope: 4.1457 / HDD
- Gas — heating-only model (no cooling term)
- Weather-normalized annual: needs a full year
Method: base-65°F degree days (US EIA / NOAA);
degree-day regression (ASHRAE Guideline 14; PRISM (Princeton Scorekeeping Method)).
