New photovoltaic system on the roof of the company headquarters in Dortmund saves 600 tonnes CO2 per year – the energy produced also powers an electric truck
In the autumn of 2013, we put one of the largest photovoltaic plants in Germany for internal consumption into operation at our headquarters in Dortmund. The 12,000 square metre plant extends over the roof of a warehouse as well as the administrative building. A large part of the power is used by us on site. On weekends, when the business rests, the solar energy is fed into the public grid.
The so-called PV system has a size of about two football fields and produces around 870,000 kilowatts per year. This amount corresponds to the average annual consumption of 240 four-person households. Through the system, we save about 600 tonnes of CO2 annually. This amount of CO2 is equivalent to that produced by fifteen 40-tonne trucks with an annual mileage of 50,000 kilometres.
TEDi also uses the solar power produced to charge the E-Truck. The environmentally friendly and low-noise 12-tonne truck supplies stores in North Rhine Westphalia. The delivery routes are optimised to the maximum range, to make the best possible use of the energy. After charging at our premises, which lasts approximately 4.5 hours and is performed several times per day, the truck can travel about 200 km with a maximum payload of 5 tonnes. It is designed to cover a daily mileage of between 150 and 350 kilometres.
With the photovoltaic system and the two electric trucks TEDi is taking two important steps towards becoming a more sustainable trading company. This is our way of giving back part of our economic success, in this case to the environment: This is what responsible business conduct means to TEDi. Since 2010, we have focused on modern environmental technology and the use of renewable energy. The German branch network is therefore following on from the energy efficient refurbishment of the headquarters and the switch to sustainable and certified green power supply both here and with our logistics. Currently, 99 percent of TEDi branches are using green electricity.
