CONSOLIDATED EDISON INC

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 2023/2024 (through January 31, 2024) occurred on January 20, 2024 when the firm sales customers' demand reached approximately 169 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 2024/2025 service area peak day demand for firm sales customers will be 235 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 2024, the company forecasts an average annual decrease of the gas peak day demand for firm gas customers over the next five years at design conditions of approximately 0.2 percent in its service area, including the effect of certain gas energy efficiency programs, the electrification of space heating and the anticipated phase-out of natural gas in certain new construction buildings in New York State. The five-year forecast in peak demand is used by the company for gas supply and capital planning purposes.
