The Stadtwerke Unna GmbH (SWU) is a municipal utility companies. The company is active in the supply of electricity, natural gas, local and district heating, energy consulting and energy services. On behalf of the municipality, it also operates the municipal underground car parks and a swimming pool.
activity
Stadtwerke Unna supply the city of Unna with gas, electricity and local and district heating. All of the natural gas is obtained externally, the electricity only partially. Around 19 percent of electrical energy is produced, fed in and distributed in block-type thermal power stations , wind turbines and photovoltaic systems in the city. In addition, the combined heat and power plants provide district heating for large residential areas, public and private buildings as well as for leisure facilities. Local heating is generated in 39 plants. They also operate the indoor swimming pool at Bergenkamp and the municipal parking garages.
The municipal utilities are both energy producers and energy distributors. Stadtwerke Unna operates widely branched networks of gas, electricity and heat lines for energy distribution. In 1998, extensive network takeovers resulted in the former upstream supplier VEW taking a 24.1 percent stake in Stadtwerke Unna. With effect from February 23, 2001, the investment, which was initially held in RWE NET AG as part of the merger of VEW ENERGIE AG and RWE AG, was transferred to RWE Energy AG and then to today's RWE RWN Beteiligungsgesellschaft as part of a universal succession mbH transferred.
In the 1990s, Stadtwerke Unna began to reorganize itself in a changing energy industry. In addition to optimizing the economic results, the aim was to optimize the ecological results: on the one hand, to reduce energy consumption and, on the other hand, to increase energy efficiency. With this in mind, Stadtwerke Unna has developed new business areas. The focus is on offensive energy efficiency advice for households and companies. This energy advice is closely linked to contracting services. The company plans, finances, installs and operates larger and smaller heating systems (conventional systems, micro-CHP) and photovoltaic systems on behalf of third parties. In the course of their strategic further development, the Unna public utility company has participated in the Trianel public utility network . The Trianel investments in the new construction and operation of a gas and steam power plant as well as in a natural gas storage facility and an offshore wind farm serve to ensure security of supply, independence from large upstream suppliers and the further development of economic and ecological optimization in energy procurement. In 2011, the municipal company provided customers with 363 million kilowatt hours of electricity, 719 million kilowatt hours of natural gas and 42 million kilowatt hours of heat.
The supply network extends over the urban area of Unna. Stadtwerke Unna receives most of its energy from upstream suppliers. In addition, they have switched to generating their own energy in the most environmentally friendly way possible. To this end, five block-type thermal power stations, a wind turbine and photovoltaic systems have been implemented in Unna. Stadtwerke Unna received the German Environmental Reporting Award 2005 from the German Chamber of Auditors in the category of small and medium-sized enterprises for the best environmental report in Germany.
history
With the establishment of the Stadt-Unnaer Gasanstalt for the production of coke oven gas, which went into operation on November 10, 1860 on today's Leibnizstraße, the later Stadtwerke Unna emerged. In 1897 gas production was relocated to Königsborn to today's Zechenstrasse. In 1907 the power supply began. In 1937 it was connected to the VEW gas network. The current name Stadtwerke Unna prevailed in 1940.
In 1975 the gas supply was switched from coke oven gas to environmentally friendly natural gas . In 1989 the former company of the city of Unna was reorganized to become Stadtwerke Unna GmbH. In 1991 the gas supply in the Massen district was taken over. In 1991 the expansion of the nationwide gas supply in all Unna districts began. In 1992 the energy advice center was opened on Massener Strasse and the first combined heat and power plant at Brockhausplatz / Gartenvorstadt was put into operation to expand the heat supply. In 1993, the Ostenberg / Billmerich wind power plant went into operation, the Königsborn and Eissporthalle combined heat and power plants in 1994, the Schürmann / Unna-Süd hydroelectric power plant in 1995 and the Freizeitbad Massen combined heat and power plant in 1996. In 1997, construction began on the new municipal utility headquarters in Indu-Park on B1 / Heinrich-Hertz-Strasse as the conclusion of the model project for municipal energy management (KEM). The move to the new Stadtwerke headquarters was in July 1998. 2001 saw the opening of the Energy Meeting Point. The virtual power plant went into operation in 2004. In 2006 Unna was the first city in the district to take part in the nationwide SolarLokal campaign . The same year saw the opening of a weather station on the SWU premises and the commissioning of the photovoltaic system at the north school center. The first civically financed solar fund ( UN-Solar1 ) was launched in 2007. It should be used to implement large-scale photovoltaic systems on school and company roofs. In 2011, Stadtwerke Unna GmbH became one of the first municipal utilities of this size in Germany to enter e-mobility. In the first step, the citizens are offered electric charging stations and three electric cars , electric scooters and e-bikes . At the same time there was a change of management, the managing director Jänig was replaced by Jürgen Schäpermeier.
environmental Protection
In 1996, Stadtwerke Unna was one of the first branches to have all operational processes audited in accordance with the EC Eco-Audit Regulation at the time. Since then, the municipal utilities have been regularly certified according to the European EMAS regulation, where EMAS is the abbreviation for Eco-Management and Audit Scheme and represents the most demanding standard in the environmental management area. The core of EMAS is the environmental management system, which defines the organizational structures and processes in corporate environmental protection. Important elements are the continuous improvement of environmental performance, the annual review of the system by an external independent expert, and internal and external environmental communication. All employees are included in the process, for example through the company suggestion scheme, notices, the intranet, internal information materials and special EMAS information days. This is intended to help employees identify with the company's environmental protection interests and to ensure that environmental management is “lived”.
"Very good" was the rating of the environmental expert after the annual eco-audit of the municipal energy company on May 19, 2011. Stadtwerke Unna can continue to show the seal for successful environmental management according to EMAS II (EU eco-audit) and ISO 14001.
The successes are remarkable: In the past year alone, Stadtwerke Unna saved 125,637 tonnes of climate-damaging carbon dioxide through their ecological improvement measures. The incentives for all customers to save energy and use it more efficiently range from energy checks for companies to e-tips for consumers. At the same time, the municipal utilities successfully promoted the use of renewable energies: 81 percent (FRG: 17%) of all SWU electricity comes from renewable energies, only 5 percent (FRG: 25%) from nuclear energy and 14 percent (FRG: 58%) ) from fossil fuels such as oil, coal or natural gas.

In 2011, Stadtwerke Unna belonged to 76% of the commercial operations of the city of Unna, the district town of Unna will hold the remaining 24% percentage share in trust after the RWE stake has expired.
