CDDs: Midwest Cooks, Others Cool

August 13, 2025 

Cooling Degree Days (CDDs) for the week ending August 9 were lower year-over-year for most of the retail regions served by ENGIE. However, the PJM jurisdictions that include Ohio, Illinois and Michigan were a different story. These locales, part of the East North Central census region, saw temps that far exceeded those of last year. Cumulatively speaking, all ENGIE regions have been warmer than normal this cooling season.
