The DB Energie GmbH is a subsidiary of Deutsche Bahn AG , the scope of duties in the production, procurement and supply of energy sources, mainly electricity and diesel , but is also of natural gas, heating oil and district heating. In addition to the DB Group, the company also looks after other customers from industry and commerce as well as private households. The maintenance, planning and construction of energy technology facilities, such as B. train preheating systems , also belongs to the area of ​​responsibility.

history

On November 29, 1996, the traction power division was spun off into DB-Energieversorgungs GmbH & Co. KG ( DBEnergie for short ) as a legally independent company, which started operations on January 1, 1997. On December 11, 1998, the company was renamed DB Energie . On January 1, 2000, the company took over the energy supply of train stations and operating points, and on January 1, 2001 also the services of DB Tank Service . Since January 1, 2006, the company has also taken on the internal supply of gas and heat.

Around 1997 the DB Group planned to sell the energy division. After a reorganization of DB Energie, these plans were later discarded.

At the end of 2000, the company announced that it would buy and sell electricity on the Frankfurt electricity exchange in the future . At the same time, the company should break away from full supply contracts.

In 2002, the company achieved sales of 1.3 billion euros with around 1940 employees. In 2003 it received EUR 74 million in funding for the expansion of the energy supply systems. In November 2003 the company had 35 customers who did not belong to the DB group.

In 2013 the company took over the traction power supply systems of the S-Bahn Berlin from DB Netz. These include a. 86 rectifier plants and 720 kilometers of medium-voltage cables.

business

The company has around 13,000 commercial customers at 5600 train stations and is Germany's fifth largest energy supplier.

Traction current

The so-called traction current is made available to the trains of Deutsche Bahn and other railway companies in a single-phase power network as alternating current with 15 kV and 16.7  Hz - in contrast to the three-phase three-phase network for industrial and household use with usually 50 Hz.

The Germany-wide energy transport is its own about 7800 km long 110-k V - high-voltage network handled with around 25,000 masts. The outflows from the 175 substations form the property boundaries between DB Energie and DB Netz.

In addition to the power generation in own railway power plants , the current network of Deutsche Bahn about is Bahnstromumformerwerke and - umrichterwerke with the normal 50 Hz mains connected. DB Energie can use these to obtain additional electricity or feed excess electricity into the public three-phase network.

The 180 substations and 50 generating plants are monitored from the main control center (HSL) in Frankfurt am Main. A replacement control line has been set up in Limburg an der Lahn. The HSL controls the high voltage network and coordinates the traction power generator. There are also seven regional central switchboards (Berlin, Borken (Hesse), Karlsruhe, Cologne, Lehrte, Leipzig, Munich), which are responsible for the operational management of the overhead line. a. operate the 83,500 switches installed there. DB Energie operates two additional control centers to supply power to the two direct-current S-Bahn networks in Berlin and Hamburg. Converters and converters are controlled from five machine control stations (Berlin, Lehrte, Cologne, Borken (Hessen), Karlsruhe).

The billing of traction energy in electric vehicles is carried out using electronic energy meters built into the vehicles. The energy used or fed back is read out remotely from the control center via a GSM modem. Delivered traction energy is billed according to the traction current price system.

The annual traction power requirement is around eleven terawatt hours, which corresponds to the annual consumption of a metropolis like Berlin. 90% of the electrical traction energy (status: 2003) is covered by the railway's own 16.7 Hz network; in addition, 10% is drawn from the public 50 Hz network to cover peaks in demand. Within a few seconds, fluctuations in demand of up to 300 megawatts occur in the 110 kV traction power network.

Currently, almost 10% of traction electricity comes from hydropower plants in Germany. In the future, the proportion of sustainably generated electricity is to be further expanded. For example, DB Energie concluded contracts with RWE (900 million kWh / year), E.ON (600 million kWh / year) and the Austrian Verbund AG (300 million kWh / year) for the supply of electricity from hydropower plants . This is intended to increase the proportion of traction electricity from hydropower to over 20%.

Additional Services

To supply points, signal systems, depots, train stations and administrative buildings, Deutsche Bahn operates around 100 decentralized 50 Hz networks, the energy of which is mainly taken from the public network. Eight control centers switch and monitor these networks.

The company operates 190 petrol stations nationwide, supplying around 10,000 diesel -fueled train journeys every day . DB Energie sells more than 450 million liters of diesel per year. In addition, the filling stations provide heating and engine oil , sand and the urea solution AUS 32 for exhaust gas aftertreatment. More than 200 railway transport companies that do not belong to the Deutsche Bahn Group also make use of these services.

Private and business customer business

This article or section needs to be revised: Strange wording and heading, what is relevant is less who is being supplied, but what. Does "electricity from the socket" have its own name?
Please help to improve it , and then remove this flag.

Since June 28, 2017, DB Energie has entered the private customer business under the DB Strom brand and thus also supplies normal household customers nationwide.

Offers for business customers are marketed under the DB Energie brand.
