Seasonal Outlook (2018 Summer)

Summary of Summer Operating Conditions SERC’s independent review of the Region’s demand and capacity shows that summer peak reserve margin projections have been consistently above ~20% over the last three years, which indicates there are sufficient resources to meet the load during the summer peaks. Although entities performed extreme weather analysis for the summer, summer conditions are expected to be similar to 2017. The operational planning studies include the most up-to-date information, including load forecasts, transmission and generation outages, and firm transmission commitments for the time period studied. Additionally, summer hot weather scenarios are included in the operational planning studies to determine if unique operational challenges exist for the upcoming summer season.
