Ameren: Load Capacity

The Ameren Illinois Company (AIC) hosting capacity maps display a high-level visualization of the available hosting capacity for interconnecting distributed energy resources (DER) to an AIC electrical system. Hosting capacity is defined as the approximate amount of generation that can be accommodated at a given point in time on the system without impacting reliability, requiring specialized inverter settings, or without requiring system modifications. The capacity values are meant to provide the user with a general idea of capacity at a location, however it is not guaranteed and/or may change at any time. All applications for interconnection will still require a full engineering review subject to Illinois Administrative Code guidelines and may require additional system modifications that could increase interconnection costs.
