Energy management systems are technologies that monitor and optimize energy consumption in buildings and facilities.
Using meters and sensors, energy management systems (EMS) enable real-time monitoring of the various energy flows in the building and allow targeted adjustments to smooth consumption peaks and make optimal use of self-generated energy. EMS also enable energy consumption to be adjusted to available supply through dynamic load management, promoting efficiency and creating greater transparency by providing production and consumption data.
Definition of an EMS
Renera AG, with the involvement of experts, has developed the following definition for EMS, which is intended to support comparability of the systems:
An EMS enables the systematic recording and communication of energy flows (consumption and production).
An EMS automatically controls different installations/appliances (e.g. heat pumps, charging stations, etc.).
An EMS can communicate with and control at least two different consumers (e.g. electric car charging station and heat pump).
An EMS consists of facilities local to the customer and optionally includes other systems.
The recording of data is decentralized at the customer's site. The processing and generation of control signals is done either centrally in a cloud solution/server or decentrally directly within the system installed at the customer's site.
An EMS is operated either independently or coupled to the existing systems of utilities, grid operators, metering service providers, installation companies or other users, such as energy data management (EDM), SCADA, etc. The EMS can also be used as a centralized system.
