The energy park at the DMG MORI Global Headquarters in Winterthur, Switzerland
GILDEMEISTER energy solutions Innovative energy products and concepts for all industries A flagship project when it comes to self-generating, storing and utilising energy is the DMG MORI Global Headquarters in Winterthur, Switzerland. The project was instigated by the energy efficiency program from the DMG MORI group, the parent company of GILDEMEISTER energy solutions, with the objective to reduce energy costs across the entire company by 30 per cent. Alongside efforts to improve energy efficiency, the integration of renewable energy sources was a major consideration to increase the building’s self-sufficiency level and to create long-term savings.

With 42 solar tracking systems of the SunCarrier brand, Winterthur is now home to an impressive energy park. The systems can yield up to 40 per cent more energy compared to fixed photovoltaic systems, which enables a better spread of the energy yield throughout the day.The solar panels have a power output of 280 kWp, generating around 330,000 kWh of electricity per year – a figure that equates to enough energy for 100 households for one year. Both the building and the integrated e-charging station are powered by renewable energies, and the high-speed charging option for electric vehicles to charge in 30 minutes is highly pop-

ular both with external e-vehicle drivers as well as for the internal e-mobility fleet. To ensure that vehicles can still be charged with green energy during the night, when the solar systems are not generating electricity, a storage-system has been incorporated into the whole concept. The installed CellCube FB 200-400 has a power output of 200 kW and a storage capacity of 400 kWh. Based on the vanadium redox flow technology, the energy storage system is freely scalable in power output and capacity and features a notably long service life with almost unlimited cycles of charging and discharging.
The storage system does not only supply energy to the e-charging station, it also maximises the facility’s self-consumption. The storage unit, produced by GILDEMEISTER energy storage GmbH inVienna, can also be used to safeguard sensitive areas, to even out peak loads or as an entire off-grid solution. Once the storage system in Winterthur is fully charged with its 400 kWh capacity, it is capable of providing 40 households with 24 hours worth of energy, or an electric car with enough energy for around 2,800 kilometres of driving. The energy efficient construction standard as well as the integration of renewable energies and innovative storage technology will result in savings of around five million Swiss Francs in the next 30 years.The site’s current savings and expenses can be observed in real time with an integrated monitoring system called GILDEMEISTER energy monitor.With innovative systems and products, GILDEMESTER energy solutions is a competent partner, who enables energy-intensive users to gain control of their own energy supplies.
