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 = 19979 + -9.1359·HDD + 6.3478·CDD
- Heating slope: -9.1359 / HDD
- Cooling slope: 6.3478 / CDD
- 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)).
