Top Tegel is a commercial office property in Berlin with a total area of approximately 62,000 m².

In phase I, a PV system with a capacity of 420kWp was installed.

In Phase II, CHP systems with a nominal electrical capacity of up to 500 kWe are planned to be installed in various Top Tegel buildings, including micro gas turbines, serving as CHP units.

Phase III includes 22 EV charging stations that are already in operation, controlled by a 250 kWA load management system – with the plan to increase the number to 100 EV charging stations.

A battery (electricity storage) is under design to ensure the supply for 100 EV charging stations.
