The steam actual hourly peak demand in CECONY’s service area occurs during the winter heating season and during the winter of 2023/2024 (through January 31, 2024) occurred on January 17, 2024 when the actual hourly demand reached approximately 6.7 MMlb per hour. “Design Weather Conditions” for the steam system is a standard to which the actual hourly peak demand is adjusted for evaluation and planning purposes. The company’s estimate for the winter of 2024/2025 hourly peak demand of its steam customers is about 7.7 MMlb per hour under Design Weather Conditions. The company forecasts an average annual decrease in steam hourly peak demand in its service area at Design Weather Conditions over the next five years to be approximately 0.5 percent. The slight decrease reflects continued lower commercial building occupancy levels in the aftermath of the COVID-19 pandemic and customer migration to other heating sources. The five-year forecast in peak demand is used by the company for steam supply and capital planning purposes.

On December 31, 2023, the steam system was capable of delivering approximately 11.4 MMlb of steam per hour, and CECONY estimates that the system will have the same capability in the 2024/2025 winter.
