Load Studies are used to identify overall energy use in kWh, as well as peak usage on an hourly, daily, weekly, or monthly basis. The load study data can offer insights into possible better management of load utilization that can result in significant reductions in energy costs. 

California Office of Statewide Health Planning and Development (OSHPD) requires the performance of a 72-hour load study to confirm the capacity of feeders whenever loads are to be added to existing panels. Accurate reporting of existing loads can reduce the need to increase feeder capacity.

The graph below can show the behavior of an individual load, or even an entire plant or facility. It tracks energy use, shows the demand power (as measured by the utility) to highlight when peak demand occurs that results in higher utility penalty charges, as well as total consumption. Graphs of watts, current, and power factor over time provide a full assessment. These graphs can be exported to Excel for analyzing energy savings opportunities.
