EUE. A measure of the capability to continuously serve loads.
Expected Unserved Energy (EUE)
Expected Unserved Energy (EUE) is a measure of the generation and transmission system’s capability to continuously serve all loads at all delivery points while satisfying all planning criteria. EUE is energy-centric and analyzes all hours of a particular year. Results are calculated in megawatthours (MWh). EUE is the summation of the expected number of megawatthours of load that will not be served in a given year as a result of demand exceeding the available capacity across all hours. Additionally, this measure can be normalized based on the assessment area’s total Net Energy for Load. Normalizing the EUE provides a measure relative to the size of a given assessment area.
