"Junction box styling" school project

Berlin's children and young people design junction boxes and grid stations in their area.

Under the slogan “Grey is so yesterday”, we have been running the “Junction Box Styling” school project since 2009. The project allows school classes to give free rein to their creativity on electricity boxes in their local neighbourhood. Our project partner is meredo e. V.

The initiative is aimed at pupils from Year 5 onwards. During a one-week project week, each class designs around 15 electrical boxes in their neighbourhood. The selected applicants get to be creative between March and October.

We want to give as many pupils as possible the chance to take part in the project. For this reason, schools may only take part again after a minimum of five years.

What is a junction box?

A junction box, also known as a cable distribution cabinet, distributes energy to multiple domestic connections. It is the interface between the grid stations and households. In Berlin there are around 18,000 junction boxes, which distribute energy to 2.4 million households.

Competition "Most Creative Junction Box"

Since 2013, every participating school has been able to enter its most attractive junction box into a competition. In this way, we recognise the commitment of the children and young people. A jury selects the winners of the most attractive electrical boxes in one or two categories (depending on the number of entries) and for transformer stations.

In addition, we also award a public vote prize every year. Voting takes place via Instagram under “stromkastenberlin” and on our website. The prizes for the best-decorated electrical boxes and transformer stations are presented at an invitation-only celebratory prize giving ceremony.
