The Stadtwerke Tübingen GmbH (SWT) is a local utility company for electricity, natural gas, water, district heating and telecommunications. The swt are the basic providers of households and businesses in the university city of Tübingen and the region. In addition, the swt also operate the Tübingen baths and parking garages. They organize bus transport in the city and also provide transport services through their subsidiary Stadtwerke Tübingen Verkehrsbetrieb GmbH. The company is 100 percent owned by the university town of Tübingen.
history
In 1862 the first gas works was founded specifically for gas lighting. In 1879 a central water distribution system was introduced. In 1902 the first Tübingen power station was built in Nonnengasse.
In 1930, the various plants were merged to form the municipal company Stadtwerke Tübingen. In 1951 swt also operated the municipal swimming pools: the outdoor pool, the “North indoor pool” and the historic “Uhlandbad” indoor pool.
In 1982 the company was reorganized from its own municipal operation into a private company in the form of a GmbH. In 1984 Stadtwerke Tübingen moved from Nonnengasse to a modern company building on Eisenhutstraße in the southern part of Tübingen. In 1986 the power grids of Bühl, Hagelloch, Hirschau, Kilchberg, Pfrondorf and Weilheim were taken over. Together with the state of Baden-Württemberg, the joint power plant Tübingen GmbH (GKT) was founded in 1994 and converted to combined heat and power (CHP). In 1995, Stadtverkehr Tübingen GmbH (SVT) was established in cooperation with the bus companies Kocher and Schnaith.
In 1997 the Parkhausgesellschaft Tübingen mbH was merged with the Stadtwerke Tübingen: takeover of the three parking garages König, Stadtgraben and Metropol. In 1998 the telecommunications company TüNet GmbH was founded as a 100% subsidiary.
In 1999, the Südwestdeutsche Stromhandels GmbH (SWS) was founded together with 30 other municipal utilities. In the same year the block-type thermal power station (BHKW) Obere Viehweide was built. In 2000, Stadtwerke Tübingen and five other municipal utilities in Baden-Württemberg founded EnergiePartner Süd GmbH. In 2001, Stadtwerke founded ImmoTherm GmbH together with Technischen Werken Friedrichshafen and Siedlungswerk Stuttgart. In 2003 Bebenhausen was connected to the Tübingen water network. In 2004 the natural gas supply in Pfrondorf was put into operation. In 2005 the Stadtwerke founded the KommunalPartner Süd Beteiligungsgesellschaft mbH & Co. KG and the SüdWestStrom Kraftwerksbeteiligungs GmbH together with other companies in the energy supply industry. In 2006 the two subsidiaries Stadtverkehr Tübingen GmbH and TüNet GmbH were integrated into the Stadtwerke Tübingen as operating branches. The swt received the electricity concession in Unterjesingen and put the high-pressure natural gas pipeline between Tübingen, Herrenberg and Rottenburg - a joint project of the three cities and their municipal utilities - into operation. In 2007 the municipality of Ammerbuch also awarded the electricity license to swt after the gas license. In Waldenbuch, swt opened the first swt customer advice office outside of Tübingen.
In 2009 with the takeover of the network in Ammerbuch, Dettenhausen and Waldenbuch, swt's electricity network grew by around 50%. The Ammerbuch community works began its work. Bürger-Energie Tübingen eG was founded together with the Volksbanken Tübingen and Ammerbuch. Swt took part in the North Sea wind farm BARD Offshore 1. Together with the city of Horb, swt founded Energie Horb am Neckar. In 2010, swt founded TüBus GmbH, its own bus operating company, which was to provide over half of Tübingen's city transport services from 2011. The trigger for this change was the EU regulation 1370/2007 . The swt put their first e-mobile and the first e-charging station on Eisenhutstrasse into operation. The extension building in Eisenhut was completed.
Divisions
TüStrom
Swt obtains the majority of its electricity needs from Südwestdeutsche Stromhandels GmbH, a joint venture between numerous municipal and municipal utilities in southern Germany. By 2020, the swt would like to generate half of Tübingen's electricity needs from renewable energies such as wind, water and sun.
According to § 42 EnWG on electricity labeling , all energy supply companies in Germany are obliged to indicate the origin of the electricity they supply. Stadtwerke Tübingen published the following values for 2015 (see comparative values from 2012 and 2013):

Combined heat and power
Most of the electricity generated from natural gas comes from systems with combined heat and power (CHP), in which the heat generated during electricity generation is not released into the environment as waste heat, but is used for district heating.
Renewable energy
An important renewable energy source for swt is hydropower. Electricity has been generated in hydropower plants on the Neckar since the beginning of the 20th century. The run-of-river power plant operated by Energie Horb am Neckar, in which swt has a half share, produces around 2.3 million kilowatt hours of electricity per year from hydropower. This is enough to supply around 600 four-person households.
In addition, swt operate several photovoltaic systems in the city and the region. Stadtwerke Tübingen invest in wind and solar parks and supply over 12,000 customers with green electricity.

1.2 million kWh | 571 t |
| wind | 70.2 million kWh | 33,415 t |
| total | 195.0 million kWh | 92,820 t |
TüGas
Households, commercial and industrial customers are supplied with natural gas by swt . Almost the entire Tübingen urban area and most of the city districts are connected to the natural gas supply.
TüWasser
75% of the drinking water in Tübingen comes from Lake Constance , 25% is extracted from the groundwater body of the Neckar valley by the swt with its own wells. In the mixing tank on the sand, Lake Constance water and water from the lake are mixed in order to achieve a degree of hardness of around 14 ° dH (degree of German hardness). From here, both the core city and most of the city districts are supplied with drinking water. Tübingen has been a member of the Lake Constance water supply since it was founded in 1954.
The districts of Unterjesingen, Hagelloch, Hirschau and Bühl are supplied with water from the Ammertal-Schönbuch group by the municipal utilities; Pfrondorf and Herrlesberg receive pure Lake Constance water. The Tübingen drinking water is in the middle hardness range II.
Around five million cubic meters of water flow through the Tübingen water network every year.
TüWärme
Stadtwerke Tübingen operate natural gas-powered combined heat and power plants, which achieve a high degree of efficiency through the simultaneous generation of electricity and heat. The swt have increased the share of combined heat and power generation in electricity generation by building block-type thermal power stations.
TüNet
The Stadtwerke's telecommunications / TüNet division offers data lines, telephony, internet services and server housing for business customers. TüNet mainly works with fiber optic technology with high bandwidths - but also with copper and radio connections.
TüBus
Since the 2000s, the swt have been organizing local transport in and around Tübingen together with partners. In 1995 Tübingen Stadtverkehr was released from direct urban management and SVT - as Stadtverkehr Tübingen GmbH - was founded. In addition to Stadtwerke Tübingen GmbH, the bus companies Kocher and Schnaith were involved in the company. The SVT belongs to the Verkehrsverbund Neckar-Alb-Donau GmbH (naldo) founded in 2001. In 2006 the GmbH was dissolved and integrated as a branch of the Stadtwerke Tübingen GmbH. Stadtwerke Tübingen Verkehrsbetrieb GmbH, a subsidiary of Stadtwerke Tübingen, has provided the majority of transport services in Tübingen since January 1, 2011. A total of 67 buses are in use for the TüBus.
TüBäder
The swt operate an outdoor pool and two indoor pools: the Uhlandbad in the city center and the indoor pool north on Waldhäuser Ost.
outdoor pool
The Tübingen outdoor pool is located on the western outskirts in the Neckar valley. It was modernized in the 1990s. The Tübingen outdoor pool has a solar thermal system with a total area of approx. 470 m². The absorbers of the solar thermal system are installed on the roofs of the company buildings. The heat generated in this way is used to heat the children's paddling pool and the swimming pools. The solar thermal system saves around 16,000 cubic meters of natural gas per year, which would otherwise be required for operating a conventional gas condensing boiler with the same amount of heat generated.
TüParken
The swt operate the public parking garages Metropol, Altstadt-König, Altstadt-Mitte and the Neckar parking garage in the city center.
In the southern part of the city, the swt operate two multi-storey car parks intended for residents, which have both conventional parking spaces and a fully automated section.
Holdings
The traditional business activities were supplemented by company investments and start-ups in the areas of energy sales, generation and services as well as drinking water supply and local transport.
Südwestdeutsche Stromhandels GmbH
Südwestdeutsche Stromhandels GmbH (SWS), a joint venture of numerous southern German municipal and municipal utilities, offers services in the field of electricity and natural gas supply for municipal utilities. The offer ranges from procurement through balancing group and energy data management to full supply at fixed prices and portfolio management.
EnergiePartner GmbH
EnergiePartner GmbH is an association of six municipal utilities from Baden-Württemberg that jointly develop innovative energy services.
KommunalPartner Beteiligungsgesellschaft mbH & Co. KG
KommunalPartner Beteiligungsgesellschaft mbH & Co. KG, also a cooperation company of six municipal utilities in Baden-Württemberg, supports small and medium-sized municipal utilities in competition through capital participation and know-how transfer.
