Extreme Cold Drives Higher Energy Use for Delmarva Power Customers Across Delaware and Maryland

Following some of the coldest winter weather the region has experienced in years, Delmarva Power customers used significantly more energy as prolonged extreme cold drove higher heating demand.

December 2025 and January 2026 ranked among the coldest winter months of the past decade, resulting in sustained, above-average heating needs for customers, as referenced by heating degree day (HDD) data, a key indicator of heating demand.

Despite the extreme weather and elevated demand, Delmarva Power's electric and natural gas systems continued to perform reliably throughout the extended cold snap.
