April 20th 2016, an additional component for the system IREN2 could be delivered. The Power Link* allows an exchange of electric power between the medium voltage and low voltage grid in both directions. Various scenarios in production and consumption can be adjusted. For example, the Power Link alternatively behaves like a battery, as a group of consumers, or as a generator - for example, as a photovoltaic or a wind turbine. Thus, attempts at any time, regardless of wind and sun, will become possible.

*A power electronics link using inverters can connect two or more seperate medium voltage AC grids with different voltages, frequencies or phase angles.
