The EnergyIP smart grid platform is being expanded by Siemens with the addition of application software components for the German smart metering market, in a move aimed to provide power supply companies with a central IT solution for the administration of smart meter gateways and for the processing of encrypted and signed energy consumption measurement data.

This solution enables power suppliers to connect smart metering systems consisting of a smart meter gateway and smart basic meters to their central IT system. This IT solution fulfils the requirements for data protection and data security stipulated by the German Federal Office of Information Security (BSI) in its Technical Directive for Smart Energy, TR-03109.

“The growing integration of information and communication technology in power supply networks that are being developed into smart grids is increasingly focusing attention on the issue of cyber security,” noted Jan Mrosik, CEO of the Siemens Smart Grid Division. “The requirements that must be met in terms of data security – from the beginning to the end of a transmission line, including all products, systems, solutions, and processes – are getting stricter all the time. From our extensive smart grid portfolio, we are providing power suppliers and utilities with the right solutions to meet their needs.”

Siemens has designed its solution as a multi-client system. This allows the roles of distribution network operator, measurement point operator, and gateway administrator to be implemented in compliance with market rules. The software design already takes into account the expansion of market communication, which is currently being specified by the German Association of Energy and Water Industries (BDEW). This expansion pertains to the exchange of data between all market roles.

The IT solution is based on the EnergyIP platform. New market roles can be flexibly configured in order to ensure the necessary potential for upgrading in the future. The joint and separate data storage functions can also be configured for the external market participant and gateway administrator roles. The solution works with an SAP-QBS (Qualified Business Solution)-certified MDUS system (meter data unification and synchronization) with standard interfaces that is expanded in conformance with BSI and independently of the meter manufacturer.

The current version of the EnergyIP application supports BSI-compliant business processes in establishing secure connections. Other features supported are the configuration of the smart meter gateways and the basic meters, processing of encrypted and signed measurement data, and monitoring of the smart metering systems.
