history

Establishment of the municipal gas and electricity works

In 1897, when Karl Lueger became mayor of Vienna, its almost 1.6 million inhabitants were supplied with 30 GWh of electricity by three private companies, which, due to the high price of 80  Heller / kWh, was used almost exclusively by the upper class for lighting purposes: The Allgemeine Österreichische Elektrizitätsgesellschaft operated a steam center each in Obere Donaustraße and Neubadgasse and distributed direct current with 4 × 110 V; The Internationale Elektrizitätsgesellschaft generated 2000 V alternating current in the steam center in Engerthstrasse , which was converted into 110 V alternating current via transformer stations, and the 1. Wiener Elektrizitätsgesellschaft generated direct current with 2 × 110 V in the Kaunitzgasse steam center. The gas was also supplied mainly for lighting purposes by the Imperial Continental Gas Association or, in the suburbs at the time, by the Austrian Gas Lighting Company . The horse-drawn tram was operated by the Wiener Tramway-Gesellschaft and in some suburbs by the Neue Wiener Tramway-Gesellschaft . The population was very dissatisfied with both the gas companies (too high prices, selfish use of granted rights) and the trams (too high fares, too long intervals, large parts of the city not accessible).

Lueger succeeded the municipalization of the gas companies and the end of November 1899, had Gasworks taken over the gas supply of Vienna in its entirety. In 1899 the City of Vienna at the request of Lueger acquired a license for a light railway network and co-founded the Siemens & Halske AG , the banker Sigmund Reitzes the Tramway Company bought from a construction and operating company for the electrification of the tram and the expansion and operation of your lines . The municipality of Vienna had contractually reserved the right to supply electricity for the tram from January 1, 1902. In May 1899, the municipal council decided to build not only a plant for traction current, but also an 18 MW steam power plant for the delivery of light and power in order to create order in the power supply. The company Gemeinde Wien - Städtisches Elektricitätswerk , registered on May 9, 1900 , supplied electricity to Vienna's trams for the first time on April 8, 1902, and on May 12, 1902, the Mariahilf substation provided electricity for lighting purposes for the first time. In competition, the community prevented the private electricity companies from laying new cables, which is why they moved the cables in the basements from one house to the next. Since they also fought against each other, there were three connections with different power systems and voltages in many houses. Finally, the municipality of Vienna was able to negotiate the 1. Wiener Elektrizitätsgesellschaft in 1907, the Internationale Elektrizitätsgesellschaft in 1908 and the Allgemeine Österreichische Elektrizitätsgesellschaft in 1914, thereby laying the foundation for the harmonization of Vienna's electricity supply.

Founding of the heating company in Vienna

Flötzersteig waste incineration plant : Vienna's first waste incineration plant (1963), which currently (2018) produces almost 500,000 megawatt hours of district heating.

Around the mid-1960s, it became apparent that with increasing prosperity, landfills would be filled faster than expected. The New General Hospital , which is currently under construction, should also be supplied with warmth. In order to establish an economically and organizationally independent district heating supply on a large scale, the Heizbetriebe Wien Gesellschaft mbH (HBW) was founded on January 22nd, 1969 with a share capital of ATS 100,000.- by resolution of the City Council of Vienna . Franz Swaty, head of the then Municipal Department 32 - Building Services, who had already presented a concept for the future district heating supply of Vienna in 1965, was appointed managing director .

At the shareholders' meeting on April 9, 1969, the share capital was increased by ATS 120,000,000.- and, as a result, the construction of the Spittelau district heating power plant with an integrated waste incineration plant as well as the construction of a line crossing the Danube Canal into Brigittenau to the Döbling international student residence the construction of the combined heat and power plant south to supply the satellite settlement Per-Albin-Hansson-Siedlung Ost started. 14 systems with a total capacity of 47.35 MW were taken over from the then Municipal Department 52 - Municipal Housing Management on September 1, 1969 with a retroactive lease agreement. The Kagran cogeneration plant was expanded in order to also connect the Quadenstrasse residential complex with a district heating pipe. In order to be able to finance the brisk business activity, the share capital was increased by a shareholder resolution on May 14, 1970 by a further ATS 250,000,000.

Consolidation of energy companies

Wien Energie emerged from the municipal gas works, Wiener Elektrizitätswerke and Heizbetriebe Wien (HBW), which was founded in 1969 and was called Fernwärme Wien Gesellschaft mbH from April 16, 1994.

In 2013 there were extensive organizational changes in the energy sector of Wiener Stadtwerke. The former subsidiary of Wien Energie - Wien Energie Fernwärme, formerly Heizbetriebe Wien - was integrated into Wien Energie GmbH. The company "Wiener Netze" brings together Wien Energie Stromnetz, Wien Energie Gasnetz, the primary network for district heating and Wien Energie's telecommunications networks.

Company profile

Wien Energie supplies around 2 million customers, 230,000 commercial and industrial facilities and 4,500 agricultural businesses in the greater Vienna area with electricity, natural gas and heat . The company's activities include:

  • Electricity and heat generation
  • Sales of electricity, natural gas and heating and cooling
  • Energy advice and energy services
  • Heat network provision and expansion
  • Waste recycling
  • Property management
  • telecommunications

The electricity and heat production takes place primarily in the fossil-fired caloric power plants in Vienna-Simmering and Donaustadt . In addition, the company operates several hydropower plants , wind farms and photovoltaic systems as well as one of Austria's largest biomass thermal power stations in Vienna- Simmering, which is fired with renewable energy . In the electricity sector, the installed capacity amounts to 2,072  MW . The share of renewable energy sources in total production was 16.5% in 2011/12 after 10.1% in the 2009/2010 financial year. By 2030, the share is to be increased to 50%.

Wind farm

In May 1997, one of Austria's first wind turbines (rotor diameter 30 m, output 225 kW) was put into operation on the Danube Island. In addition to the locations in Vienna , Lower Austria , Burgenland and Styria , a wind farm with twelve wind turbines and an installed capacity of 24 MW has been operated in Levél, Hungary , since 2008 . In 2005 one of the highest wind farms in Europe was put into operation at almost 1,600 meters. In 2012, the Glinzendorf wind farm with nine wind turbines and an installed capacity of 18 MW was built in cooperation with EVN . In October 2014, the Steinriegel wind farm was expanded by eleven wind turbines ( Enercon E-82 , rotor diameter 70 m, power 2.3 MW) with a total power of 25.3 MW. From autumn 2015, 15 wind turbines (12 of them Enercon E-101 , rotor diameter 101 m or rotor diameter 85 m power 3 MW) with a total power of 42.9 MW will deliver electricity in Pottendorf , it was designed as a public participation model.

Biomass

Wien Energie operates biomass heating plants in Purkersdorf and Trumau . Since 2006, the Simmering biomass cogeneration plant has been supplying around 48,000 Viennese households with electricity and 12,000 households with district heating. This corresponds to around 4% of the output of the neighboring and roughly identical power plant Simmering Unit 1.

Photovoltaics

Wien Energie's photovoltaic systems are in operation at various locations in Vienna and Lower Austria. Wien Energie has been building a number of photovoltaic systems with loans from citizens since 2012 . The largest inner-city solar power plant, which went into operation in December 2013, has a roof area of 9,000 m 2 on the building complex of the Wien Mitte train station with 1,424 solar modules and a standard energy capacity of over 0.3 GWh per year, which corresponds to an average output of approx. 35 kW.

District heating

Wien Energie supplies around 350,000 households and businesses as well as more than 6,800 major customers (such as St. Stephen's Cathedral , Schönbrunn Palace , various hospitals, train stations, official and university buildings) with space heating and hot water , making it a top spot in Europe. The Viennese district heating network with a total length of almost 1200 km is divided into a primary and a secondary network. In the primary network, large amounts of heat are transported through the whole of Vienna at high pressure and temperature. It flows into the heavily branched secondary network that leads to the individual buildings and there transfers the heat to the house systems via converter stations. The primary network has belonged to Wiener Netzen since August 1, 2013 , the secondary network will continue to be operated by Wien Energie. 17 generation plants at twelve locations feed hot water into the primary district heating network. In 2013, 19.3% of district heating was generated from renewable energy sources. In 2014, 25.6% was generated from renewable energy sources.

Local heating

In addition to district heating, Wien Energie also operates local heating .

District cooling

In 2009 the district cooling center in Spittelau went into operation, which among other things supplies the General Hospital of the City of Vienna , as well as the Skyline real estate project and the Ö3 radio station . In the meantime, there are also other cooling centers and systems from Wien Energie in the SMZ Ost hospital , on Schwarzenbergplatz , at the Rudolf Foundation and at the TownTown office location in the third district of Vienna. The district cooling center on Schottenring has been running since April 2013, supplying, among others, Wiener Städtische, Vienna Insurance Group, the “Uni Wien Roßau” , which is being developed at Roßauer Lände , and Raiffeisen with district cooling. In 2014, the central station district cooling center went into operation for the first time; With an output of 20 MW in the final stage, it is one of the largest district cooling projects. The first projects were put into operation in 2007 and meanwhile 100 MW of district cooling capacity are in operation.

Electric and natural gas cars

Wien Energie is involved in the “e-mobility on demand” project of the Vienna model region and in the “Vibrate - Vienna Bratislava e-mobility” pilot project, which will create the first cross-border model region for electromobility. Almost 600 natural gas vehicles are currently in use for Wien Energie and its sister company Wiener Netze .
