Energy Monitoring System (EMS) is an initiative towards monitoring total power consumption, thereby reducing energy costs and consumption for buildings and communities. The ultimate goal of the system is to reduce energy costs through improved energy efficiency and energy management control. The system collects the real-time data at regular intervals through an array of sophisticated panel meters and data loggers. These data are uploaded and recorded to an online server. Thus the past data can easily be viewed to provide a comparison between pre and post data of energy consumption. The praxis of the system extends beyond just the data collection. Thus collected data is further processed for Reporting and Monitoring.
Reporting takes into account the verification of collected data and setting energy use reduction targets. The cost and consumption data from a number of buildings can be aggregated using the web based software, thus saving time relative to manual reporting. It becomes easier to find out if there is any energy wastage or unwanted energy being used. This information can be used to prioritize energy savings initiatives and balance energy savings against energy related capital expenditure.
Monitoring includes tracking and identification of energy consumption so that cost saving opportunities can be acknowledged. EMS, by providing instantaneous energy consumption reading, can diagnose specific areas of wasted energy. Thus the system helps to manage the energy consumption and develop the performance targets for energy management. It also offers alerts through SMS for deviation of the energy consumption from the threshold level.
