The small community in the Allgäu district is a good location for a pioneering trial. Energy pioneers from Siemens and its partner companies have been experimenting here for years now, to determine the form that a future intelligent power network – a Smart Grid – can take. Intelligent controller and energy storage enable these networks to keep volatile generation and consumption in balance, thus making stable grid operation possible. Since 2011, as part of the research projects Irene and IREN2, Siemens has worked with partner entities Allgäuer Überlandwerk AG, ID.KOM, RWTH Aachen, and Kempten University to build and test a Smart Grid in Wildpoldsried. The isolated network trial was the culmination of many years of research and testing.
