Energy efficiency has a high priority for GSG Berlin. This also benefits the environment. With the operation of Berlin’s largest solar power system, its own combined heat and power plants and the expansion of the charging infrastructure for electric vehicles, GSG is making an important contribution to the realization of the Berlin goal “Climate neutral by 2050”.

Solar power for Berlin
In summer 2014, GSG installed the biggest solar system in Berlin with a total output of 6.4 MW. With this, 5,000 tons of CO2 will be saved annually. To achieve a similar savings in CO2, Berlin would have to plant 400,000 new trees. This equates to a ten-fold amount of trees in the Tiergarten, Berlin’s central park.
26,200 solar modules, which have been produced in Berlin-Brandenburg, have been installed on 43,000 square metres of the roof area of 140 roofs on 28 Berliner commercial complexes in the districts of Charlottenburg, Kreuzberg, Lichtenberg, Marienfelde, Marzahn, Pankow, Tempelhof und Wedding. The installation produces about 5,800,000 KWh of electricity annually.
