The «Maienzug»-place and the fairground in Aarau are popular locations for festivities. The previous infrastructure did not meet the requirements of large events. There were too few CEE 63 or 125 A connections. As a result, additional temporary site power distributors and satellites had to be set up for a large number of events in order to ensure the power supply. For this reason, those responsible in the city of Aarau. Aarau therefore decided to install several additional distribution cabins, some even with water connections. This means that even more events can now be organised on the two squares.
