Projects and activities of DB Energie - Examples -
Integration of Wind Energy into the Traction Power Portfolio Contracts signed with 3 different wind park operators Target: Gain Experiences with fluctuating Power Supplies Three wind power plants in Elsdorf, Märkisch Linden and Treuenbrietzen (33 turbines in total) App. 100 GWh per year (theoretical coverage of 20,000 households) Electric power (50 Hz) is fed into DB Energie s balancing group CO 2 savings of 50,000 tons plus per year 10
Increased Share of Hydro Energy in our Traction Power Portfolio Long-term deal on hydro energy (50 Hertz) closed with RWE Target: Increase Share of Renewables; use for CO 2 -free Transportation Products Power plants on the rivers Rhine, Moselle, Rur and Ruhr 900 GWh per year, from 2014 to 2028 Deal covers app. 8% of electric traction power in Germany s rail system 11
Incentives for the Installation of Photovoltaic Systems Lease contracts signed with solar companies Target: Production of CO 2 -free Energy utilizing DB Buildings and Properties Project in Frankfurt Roof of train repair shop Capacity installed: 1,100 kwp In general Further projects currently in planning or construction phase Potential of more than 50,000 kwp to be explored within the next decade 12
Heating System using Biomass harvested along DB Tracks Pilot plant realized in Southern Germany Target: Heating with Wood Chips (DB-origin, CO 2 -free fuel) Heat supply for shop, train cleaning building and offices 70 % of annual local demand covered CO 2 savings of 70% 440 kw boiler 13
Reduction of Energy Consumption Measures executed by DB Energie for DB and non-db clients Target: Improve Energy Efficiency Executing energy audits in shops, stations, offices and other buildings Installing innovative energy technologies Consulting and training of customers 14
