The LMWin Load Management Program was developed to meet an electric utility’s need for monitoring their total electric system load and for direct control of their non critical consumer loads. The program retrieves substation readings over normal voice grade communication lines, dedicated communications lines, two-way radio communication systems, or cell phone modems to perform its monitoring function. It can monitor numerous substation locations that are separately metered circuits and combine their individual loads to show a total system load. Generation can also be included in that data.
The program can control hot water heaters, A/C units, irrigation systems, and city water and sewage pumps to name a few. Only a couple of larger loads not running during a peak can make a very large difference in the utilities demand charges.
The goal of this program is to control non critical electric load when the cost of using electricity is the highest, when the utility system is at its peak demand. Typically a utility pays for that peak usage for the next year or the next few years.
