PSI and Partners Design an Interoperable Ecosystem via Living Lab Cologne

Mass business capable power management via smart meter gateways in practical test

Berlin, June 17, 2022 - PSI subsidiary PSI GridConnect GmbH has conceptualized an end-to-end interoperable ecosystem for the power management of end-customer systems in a partner network. The partners comprise the EEBUS-Initiative e.V., the consulting company BET Büro für Energiewirtschaft und technische Planung GmbH, BTC Business Technology Consulting AG, GWAdriga GmbH & Co. KG, as well as Rheinische NETZGesellschaft mbH (RNG), in whose network area the "Lindgens-Fabrik" real laboratory is located.

For the successful integration of electro mobility as well as the progressive electrification of the heating market, mature and resilient technological solutions involving an intelligent metering system must be usable in "end-to-end" processes.

This leads to new requirements, primarily in small-scale systems located in the low-voltage grid. For example, the subscriber, the network operator, and market-based roles must be enabled to perform fine-grained power management, on the basis of which system stability and new business models can be established in the course of increasing volatility in the energy market.

In this context, power management can also be used via an intelligent metering system to ensure compliance with the physical power limits at the grid connection. In this ecosystem, from the energy industry to the end device in the customer's system, it is now possible to test the real-life practical use of a wide variety of EEBUS applications and to demonstrate interoperability.

All relevant market roles are represented, which can impact relevant customer systems such as charging stations and heating systems. In particular, the parallel flexibility use of grid, sales and manufacturer-specific business models will be tested. Thus, grid operators, sales and other external market participants can exchange information on power management with the customer system, e.g. on the use of time-variable energy prices and grid charges up to participation in flexibility instruments.

The Living Lab ( offers all market participants to test their systems and products in this context. The starting signal for the live test is on June 20, 2022 in Cologne. All participating partners will be available for further information at the E-world from June 21 to 23, 2022.

EEBUS is a standard and norms based communication interface that any device and technical platform can freely use, regardless of manufacturer and technology.

The PSI Group develops its own software products for optimizing the flow of energy and materials for utilities (energy grids, energy trading, public transport) and industry (metals production, automotive, mechanical engineering, logistics). The industry-specific products, which are built from standard components, are sold both directly and via the multi-cloud PSI App Store and can also be customized by customers and partners themselves. PSI was founded in 1969 and employs more than 2,200 people worldwide.
