Advanced Load Profiling
The NES System offers a rich set of data that lets utilities roll out new services over time as conditions change. Thousands of permutations of data can be used to kick off processes or alerts. Because the NES System is a smart grid solution and not just a smart meter, the data comes from the system’s three primary elements: system software, concentrators, and meters. These elements can profile the entire metering network and leverage data.
For example, advanced load profiling can be enabled on a meter-by-meter or an as-needed basis through NES System Software. Maximum visibility is provided by choosing from up to 16 electrical values; these can be configured to be captured at intervals ranging from a few minutes to once per day. This extensive data can give utilities information about the grid’s health and efficacy. It can also provide accurate information on usage patterns, which utilities need to characterize and forecast their customer base’s energy needs for grid optimization.
