Degree Day Divide

July 29, 2025 

The regions served by ENGIE Resources are split when it comes to cooling demand year-to-date. ERCOT, which resides in the West South Central census region, is lower year to date in Cooling Degree Days, but higher than normal.  New England shares the same profile. The western jurisdictions of PJM, located in the East North Central census region, are higher year-to-date versus normal. This dynamic is also found in NYISO and the eastern parts of PJM, recognized by EIA as the mid Atlantic census region.
