Intelligent measurement systems and the smart meter gateway
The switch to renewable energies requires the fundamental modernisation of the energy industry in Germany. When energy is generated by wind, sun or water, the amount produced is subject to major fluctuations. It is also produced decentrally, at many different locations. Intelligent measurement systems are designed to ensure the optimal use of renewable energy.
They help ensure that energy always gets to where it is needed or is to be stored. The gateway, which is an additional component to the electronic meter, is the central communication unit and connects the end user with the various market participants – for example, measuring stations and distribution grid operators or energy suppliers. It collects tamper-proof consumption data which are unimpeachable in terms of instrument calibration law in a matter of seconds and transmits them to the data centre of the utility company. In accordance with the requirements of the Federal Office for Security in Information Technology, the gateway encrypts all communication connections and controls access in such a way that only known subscribers and devices can access the data. The consumption of district heating, gas or water can also be measured by smart meter gateways.
Households themselves can better control their own consumption and reduce their energy costs – for example, through the preferential use of consumption times when low tariffs apply. The systems are not “actively read remotely”; instead, they transmit the meter values independently.
