At our technology sites in Germany, we are increasingly relying on solar energy. By the end of 2018, we were already operating more than 300 of our own solar photovoltaic plants overall. In total, the plants have a capacity of just under 4,000 kWp (kilowatt peak). Moreover, the existing plants yielded over five percent more in 2018 than in the previous year. In this way, we are reducing our ecological footprint by more than 1,700 metric tons of CO2 every year. The construction of another large plant at our site in Winterfeldstrasse in Berlin has run into delays due to structural requirements and will likely only be completed in the third quarter of 2019.
Over the coming years, our goal is to equip further sites with photovoltaic plants. In 2018, we drew up a concept specifying how we can render more roof space usable for photovoltaic systems. Our internal energy service provider, Power & Air Solutions, is responsible for installing the systems.
