The Kraftwerke Mainz-Wiesbaden AG is a regional energy company in Mainz with 400 employees and generated with two gas power plants at the site Ingelheimer Aue in Mainz current . Furthermore, the company is a steam and district heating supplier from cogeneration for industrial companies in the region and the Mainz Fernwärme GmbH.

The company is owned by the Mainz public utilities and ESWE supply . The HEAG Südhessische Energy AG was until the spring of 2007 also involved, but withdrew and sold its shares.

history

The Mainz-Wiesbaden power plants were created in 1931 from the merger of the Wiesbaden and Mainz power plants. In 1958, 1963 and 1966, three coal blocks with an electrical output of 100 MW each were connected to the grid in power plant 1. In 1977, Power Plant 2 went online with a combination of a steam turbo block and an upstream gas turbine (combi block). Power plant 2 currently serves as a cold reserve and was identified by the Federal Network Agency in August 2011 as an essential component (350 MW out of a total of 1009 MW in southern Germany ) of the reserve capacities for an exit from nuclear power after the moratorium . This means that there is no need to keep a nuclear power plant that has already been shut down as a reserve. In 2000 the three coal units in power plant 1 were shut down. In 2001 the new 400 MW combined cycle plant went into operation on the Ingelheimer Aue . Friedrich-Ernst von Garnier designed the facades of the power station building.

In July 2013, Kraftwerke Mainz-Wiesbaden took a majority stake in the Karlsruhe project developer Altus AG , which is active in the renewable energies sector. The aim is to sustainably strengthen this business area.

Power plant planning

Formerly planned coal-fired power plant

KMW complex

KMW planned to build a coal-fired power station on Ingelheimer Aue . After construction halted shortly after construction began in 2009, the project was officially ended in June 2012.

The power plant should have an electrical output of 820 MW and an efficiency of 46 percent; in addition, up to 300 megawatts of district heating should be extracted by means of combined heat and power. The general contractor for the key trades was Siemens AG with a scope of supply of 940 million euros; IHI was to supply the steam boiler in cooperation with AE&E . At the beginning of 2007, the Mainz city council voted 44 to 16 in favor of the construction of the new power plant. Against the planned construction of the coal-fired power station on the Ingelheimer Aue, u. a. the citizens' initiatives coal-free Mainz e. V. and Kein Kohlestrom Wiesbaden, who fear the planned power plant will have a massive impact on the entire region and the environment. As early as May 2007, over 2500 people demonstrated against the planned coal-fired power plant on the Rhine Bridge between Mainz and Wiesbaden. The immission law approval procedure according to BImSchG and the water law planning approval procedure began on October 1, 2007.

A local campaign to switch electricity providers was started with the aim of putting KMW under pressure. The campaigns against the construction of a coal-fired power station Mz / Wi were u. a. Supported by initiatives and associations from the region (BUND, AKU (Working Group Environment Wiesbaden)), doctors' initiatives in Mainz and Wiesbaden. In December 2008 they formed the Alliance for a Coal-Free Region Mainz Wiesbaden e. V. merged.

Demonstration against the planned power plant in 2007

The CDU Mainz, the majority behind the new building plans in 2007, decided on March 18, 2008 to oppose the project. On January 20, 2009, the Structural and Licensing Directorate South, as the responsible licensing authority, issued the preliminary approval under immission control law as well as the parallel water law approvals. The completion of the power plant was originally planned for 2013/14. Construction began in May 2009. In the local elections on June 7th, 2009, the Greens and ÖDP as opponents of the power plant received significant increases. The CDU, which was against the power plant, lost significantly in votes, the FDP, as the power plant supporter, gained votes. Due to the pending legal proceedings and the request of the competent court, KMW agreed in the summer of 2009 to suspend the construction work. After the SPD suffered heavy losses here and in the subsequent federal election in 2009 , it also decided not to advance the project any longer. On September 28th, the power plants announced that the project was on hold due to the lack of funding. The approval authority SGD Süd then withdrew the immediate execution.

Heating platform

In 2010, KMW AG announced that it was considering the construction of a second combined cycle power plant instead of the coal-fired power plant. Accordingly, the profitability of such a project should be examined. After completion of this investigation, a Europe-wide tender could take place. This second power plant, which is intended for peak and medium loads, should be able to go online in 2015 at the earliest. This was justified with the meanwhile changed market situation for coal and gas.

Since 2015, KMW AG has been considering expanding the Ingelheimer Aue into a central heating platform. At several information evenings, the management board of Kraftwerke Mainz-Wiesbaden AG explained the company's ideas for building a large combined heat and power plant in combination with a district heating storage facility on the KMW site to the citizens. The power plant has a modular structure and consists of 10 independent gas engines with an electrical output of 10 MW each, which are supplied by the manufacturer Wärtsilä . This enables flexible operation and the individual gas engines can be started up or shut down within a few minutes. The power plant is operated in combined heat and power , i.e. In other words, district heating is also generated in addition to electricity . The power plant was successfully started up in test operation for the first time on April 18, 2019. A date for completion has not yet been set. [obsolete] The total investment is given as around 100 million euros.

To decouple the heat and electricity market, KMW AG will build a heat storage facility in addition to the CHP unit . Its completion was planned for the end of 2018. [obsolete] The storage system can store the heat from the various CHP systems on Ingelheimer Aue for several hours. In April 2017, the ground-breaking ceremony for the construction of the power plant and the three water tanks used as heat storage took place.

Renewable energy

KMW AG has held a majority stake in ALTUS AG (seat: Karlsruhe) since 2013, which works as a project developer in the field of renewable energies ( wind energy , biogas and photovoltaics ).
