Design Day

Design Day analysis helps LDCs plan for their peak days, which usually occur during extreme cold weather conditions. This product anticipates demand on the highest flow days so that LDCs can design their natural gas distribution systems and operations to meet their customers’ needs. Design Day Analysis uses specific historical flow data as well as weather data in its modeling techniques to produce forecasts of the demand conditions on the days of extreme weather events. The models also detect seasonal, historical and other relevant trends in the data, and then incorporate these trends into the forecast.
