Weather Impact on Demand
OGE ENERGY CORP. · 2026-04-29 · Importance 47 · Surprise 48
OG&E reported lower system sales and residential MWh in Q1 2026 driven by milder weather, with total sales down to 8.0 million MWh from 8.2 million MWh year-over-year. The company attributed a $26.7 million negative quantity impact on operating revenues primarily to a 27% decrease in heating degree days. Residential operating revenues fell materially to $260.4 million from $287.3 million, reflecting the weather-driven usage decline in Oklahoma and western Arkansas. Customer count grew modestly to 915,232, but weather, not customer additions, was the primary driver of lower near-term demand and revenue.
