Load Duration Report
This report provides the ability to identify the duration, or length of time, that demand (or consumption) for a point, aggregate point, or group of points exceeds certain levels. The load duration report is useful when you are considering using demand-limiting strategies or possible capital investments.
Note: The demand component of electric rates typically constitutes 30% to 50% of total electric costs. Lowering peak demand can generate significant savings.
This report, along with the exception report and the What-If Analyzer, help identify return on investment before a project is implemented. For example, an energy manager may identify the peak for a demand meter using the exception report, then identify how much time (or the duration) that kW is above certain levels near the peak. Once determined, the What-If Analyzer quantifies the financial effect resulting from lowering the kW by that amount.
As with other reports, you may aggregate and disaggregate meters, run baselines, and normalize for square footage and temperature.
