The Stadtwerke Schwerin GmbH (SWS) was founded in 1991 and is in Schwerin -based municipal company. The owner is the city of Schwerin. The main task of the municipal utility is to supply the city with electricity, natural gas, heat and water. The group also partially includes Nahverkehr Schwerin GmbH (NVS), Ostseeland Verkehr GmbH (OLA), Freizeit-, Infrastruktur- und Tourismus Service Schwerin GmbH (FIT), WEMACOM (Telekommunikation GmbH) and the like. a.
history
With the founding of the Stadtwerke in 1991, Schwerin resumed the tradition of municipal services of general interest. The city council, which was freely elected for the first time after the fall of the Wall , agreed that the city should be supplied with electricity, gas, heat and water by a municipal company.
However, the history of Schwerin's utility industry goes back to the 19th century when the first gasworks in the city began operations on March 1, 1855. In 1919 the gas works became municipal property and was in operation until 1980. It was one of the last “island gas works” in the GDR . On the site of the former gas works, a fully automatic remote gas transfer station was set up in July 1981, which was necessary to stabilize the gas supply in the city center.
Another milestone in the communal supply industry was the construction of the first waterworks, which went into operation on June 8, 1890. Until 1954 it was the only waterworks that supplied the city with drinking water. That year the waterworks in Gosewinkel on Medeweger See followed, and in 1979 the third waterworks in Pinnow. Since 1999 Schwerin has only been supplied by two waterworks, the newly built Mühlenscharrn waterworks and the Pinnow waterworks.
In 1904 the city of Schwerin finally got its first power station . The capacity of the plant had to be constantly expanded due to increasing demand. After the First World War there were particularly extensive modernization measures that brought the city another innovation: the first district heating system. But despite all the modernizations, the old electrical works had become too small for the constantly expanding city after the Second World War at the latest and so it was finally shut down in 1972. Today Schwerin is supplied with electricity and heat by two modern heating power stations.
Products
electricity
The municipal utilities supply 123,031 customers with electricity both in the city of Schwerin and across the region. They have 4 substations, 351 transformer stations and a power grid with a length of 1,271 kilometers. It is an important concern of the municipal utility to generate electricity from renewable energies. That is why a new biogas plant was put into operation in Schwerin-Süd in the summer of 2007. Every year 51,000 tons of renewable raw materials (especially corn silage and rye meal) are to be converted into electricity and heat here.
natural gas
The municipal utility's gas network is 424 kilometers long and supplies 14,779 customers. At the two natural gas filling stations u. a. the vehicles belonging to the Stadtwerke's fleet of vehicles are also refueled, because the company has switched its 19 cars and 6 vans to natural gas for several years.
warmth
In the two heating plants in the districts of Lankow and Wüstmark , which work according to the combined heat and power principle, and in the four heating plants, the SWS generate district heating , which is distributed over a 176-kilometer route and is used for heating and preparing hot water. 3,016 customers are supplied here.
Water and sewage
Two waterworks with a total of 13 wells supply 13,775 customers in the state capital Schwerin with drinking water, which is primarily obtained from groundwater and fed into households via a pipeline network with a length of 518 kilometers. Schwerin's wastewater is treated biologically in the sewage treatment plant in Schwerin-Süd. For this reason, two digestion towers were built in 1998, which make it possible to decompose the sludge from wastewater treatment and to use the resulting gases for electricity and heat.
The SWS corporate group
EVS
Energieversorgung Schwerin GmbH & Co. KG was spun off from the Schwerin public utility company on January 1, 2004. The new company EVS is a wholly-owned subsidiary of Stadtwerke, in which, in addition to the gas, electricity and heating networks, the entire operational business of the company is integrated.
EVSV
Energieversorgung Schwerin Verwaltungsgesellschaft mbH (EVSV) was founded on April 22nd, 2004 as a 100 percent subsidiary of Stadtwerke Schwerin GmbH. The company's business activities include taking on the role of general partner in Energieversorgung Schwerin GmbH & Co. KG (EVS), whose corporate purpose in turn is to provide utility and other services in the field of energy supply, in particular electricity, natural gas and heat.
BioE
In 2006, EVS founded BioEnergie Schwerin GmbH (BioE), a wholly owned subsidiary, in order to use the new framework for the statutory promotion of electricity from biogas generation in accordance with the Renewable Energy Sources Act (EEG). Investigations have shown that the Schwerin-Süd power plant location is ideally suited for a biogas plant because of the existing infrastructure and the possibility of feeding the heat generated into the district heating network. Every year 51,000 tons of renewable raw materials are converted into electricity and heat. The electricity generated is fed into the regional power grid.
NGS
On October 1, 2005, Netzgesellschaft Schwerin mbH was founded as an independent company for the electricity and gas network in the state capital Schwerin. On January 1, 2006, E.ON edis AG acquired 40% of the NGS shares. E.ON edis AG and EVS are currently the sole shareholders of the network company. The commercial management for the network company is carried out by the SWS Group.
Energy union
Energieunion AG was founded in 1996 by the Schwerin, Rostock and Neubrandenburg public utilities with the aim of being able to participate in the liberalized European energy market through a larger trading volume.

Energieunion AG does not supply end customers, but works exclusively across Germany with industry, municipal utilities, distributors and power plant operators.
WEMACOM
The telecommunications company WEMACOM was founded in 1997 as a subsidiary of WEMAG AG. In West Mecklenburg it has an extensive telecommunications network, which originally only served to support the power supply. WEMACOM markets the free transmission capacities and, together with its partners, implements the expansion of the fiber optic network.
