The heart of smart metering is the smart meter. It is used for digitally reading out all energy consumption and infeed data. In the first expansion stage for smart energy networks, based on a cost-benefit analysis (CBA), all residential and commercial consumers purchasing more than 6000 kWh of energy are being equipped with smart meters. In addition, digital meters are being used for all generators of renewable energies such as wind power or photovoltaic plants. For BSI-compliant encryption of these sensitive data, in future the smart meter will be directly connected to a smart meter gateway.
But the smart energy network only works if the data from the smart meter are promptly transmitted to energy providers. Reliable transmission of these data to the energy provider is one of the central challenges of remote meter readouts.
In the smart grid, devolo relies on innovative IP-based data transmission with G3-PLC technology. G3-PLC uses the mains supply in the low-voltage level as infrastructure for communication. This provides the benefit of making the integration of G3-PLC exceptionally cost-effective. In addition to a smart meter and smart meter gateway, a suitable G3-PLC modem in the compact DIN rail format is installed for all consumers and generators (such as operators of photovoltaic plants). G3-PLC first sends the measurement data of all smart meters within a network area to the transformer station. From there, it can be sent to the energy provider using any medium.Technology
