The gas actual peak day demand for firm sales customers in O&R’s service area occurs during the winter heating season and during the winter of 2025/2026 (through January 31, 2026) occurred on January 24, 2026 when the firm sales customers' demand reached approximately 188 MDt. “Design weather conditions” for the gas system is a standard to which the actual peak demand is adjusted for evaluation and planning purposes. The company estimates that, under design weather conditions, the 2026/2027 service area peak day demand for firm sales customers will be 247 MDt. The forecasted peak day demand at design conditions does not include gas used by interruptible gas customers including electric generating stations. As of January 2026, the company forecasts an average annual increase of the gas peak day demand for firm gas customers over the next five years at design conditions of approximately 1.2 percent primarily due to an anticipated increase in the number of firm gas customers within the next five years. The five-year forecast in peak demand is used by the company for gas supply and capital expenditures planning purposes.
