Smart Meter Gateway

As a result of the decision taken to leave nuclear energy behind as well as the amendment of the Energy Act (“Energiewirtschaftsgesetz” or EnWG in German) made in August 2011 in Germany the federal government has, for the first time, called for the introduction of a new kind of electricity grid, a so-called “smart grid”. This intelligent electricity grid is made up of four components: a modern electricity meter (smart meter), a security module (HSM), a communications infrastructure and an intelligent interface with the different stakeholders involved (the Smart Meter Gateway).

The introduction of a smart grid has many advantages for consumers as well as for municipal works and energy providers. On the one hand the end-consumer has, for the first time, a detailed overview of their electricity needs and costs. In future they can also find out at which times of day their electricity consumption will be cheapest. On the other hand such an intelligent electricity grid allows energy providers in turn to better measure grid utilization. This makes it possible for the existing infrastructure to be better utilized and for the occurrence of large-scale, expensive blackouts to be minimized.

When it comes to such metering systems, the German federal government requires a high level of data security in the communication and reading out of the customer data. For this reason, the German Federal Ministry of Economics and Technology (BMWi) commissioned the Federal Office for Information Technology Security (BSI) with the task of formulating the requirements for the security architecture of intelligent grids. Before a metering system can be offered on the market in future, certification in accordance with the BSI Protection Profile as well as testing to ensure compliance with calibration regulations by the Federal Physical-Technical Institute (PTB) is required.
