The same models used to generate the settlement profiles can be used to forecast hourly loads. Ameren provides access to these models to Retail Electric Suppliers (RES) via the link below. Each RES shall use these models in conjunction with its own forecasts of the independent variables and its customer usage to generate hourly forecasts for scheduling purposes. The forecast should be adjusted to reflect distribution loss factors so that the load forecast represents load at the transmission voltage level. The RES may acquire historical data on customer usage, as described in Chapter 13 of the RES Handbook, to assist in forecasting.
The Ameren load profile forecasting service allows each RES to forecast their customers’ electric usage from one to seven days in the future. These forecasts can then be used to schedule electricity generation to meet this demand.
