EMS are computer-aided tools that monitor, control, and optimize the performance of the generation and transmission of electric utility grids.

Energy Management Systems can be used to centrally control devices like HVAC units and lighting systems across multiple locations. EMS also provide metering, sub-metering and monitoring functions that allow facility managers to gather data and insight to make more informed decisions about energy activities across their sites.

Operating Systems EMS rely on a model based approach. Traditional planning models and EMS models were always independently maintained and seldom in synchronism with each other. Using EMS software allows planners and operators to share a common model reducing the mismatch between the two as well as cutting model maintenance.

A Common User Interface allows for Easier Information Transition from Planning to Operations

EMS Suppliers began to deliver solutions based on industry standard hardware platforms with Windows based solutions and blade servers occupy a fraction of the space previously required; a blade rack of 20 servers occupy the same space previously occupied by a single server.

Energy Efficiency EMS can also refer to a system designed to achieve energy efficiency through process optimization by reporting on granular energy use by individual pieces of equipment. Newer, cloud-based energy management systems provide the ability to remotely control HVAC and other energy-consuming equipment, gather real-time data and generate intelligent guidance on finding and capturing the most compelling savings opportunities.
