The joint power plant Bremen (GKB) is a gas and steam turbine power plant in the Bremen district of industrial ports . It is located on the ArcelorMittal steelworks site in the immediate vicinity of the Mittelbüren power plant to the east, but has no connection whatsoever with it - apart from the joint operator and joint infrastructure.

technology

The power plant has an installed capacity of 444.5 megawatts and is expected to produce around 1.8 billion kilowatt hours of electrical energy per year. It could theoretically cover the annual requirements of over 500,000 private households in Bremen. Most of the energy, however, is fed into the Deutsche Bahn network; whose subsidiary DB Energie will purchase an annual output of 165 megawatts. For this reason, among other things, the chosen location was an obvious choice, since in addition to the appropriate infrastructure and natural gas supply lines, some of the necessary electrical equipment, such as a so-called fully static frequency coupling, is already available. This converts the electricity generated by the GKB with a frequency of 50 Hertz into traction current with 16.7 Hertz. Another converter is also installed. In addition, it is a power plant site that has been approved for a long time.

The block of the GKB is extremely compact and will only have a relatively small footprint. The dual use of this type of power plant - gas combustion, steam generation with the help of the hot exhaust gases from the first process - gives it a net efficiency of 58.29 percent in the thermodynamic cycle, making it one of the most efficient conventional power plants . It can be used very flexibly in power plant management and is an ideal medium- load power plant due to its short start times and the possibility of rapid load changes . So z. B. If necessary, the output can be reduced to zero within 15 minutes. With these properties, the GKB should serve as a supplement to the renewable energies that are not always available in constant quantities . Compared to other power plants using fossil fuels, it emits far less climate-damaging carbon dioxide - only 360 grams per generated kilowatt hour. A cell cooling tower also ensures that the warm cooling water is cooled before it is fed back into the cycle and fed into the Weser. It must not be warmer than 30 degrees Celsius to avoid excessive warming of the Weser.

Building history

As early as 2004, the Bremen energy supplier swb AG entered into negotiations with DB Energie about the construction of a new coal-fired power station in Bremen, in order to continue to guarantee a safe and constant supply of traction current. However, these plans were abandoned in August 2007 for economic reasons. From the beginning of 2009, ideas for a gas and steam turbine power plant were dealt with and the plans were presented to the politically responsible - including at the end of January 2010 in the Burglesum advisory board .

In March 2011 , the joint power plant Bremen GmbH & Co. KG was established as a cooperation of several partners. The shareholders are swb (51.76%), Mainova AG (25.1%), TOBI Gaskraftwerksbeteiligungs GmbH & Co.KG (16.19%), ovag Energie AG (4.95%) and DB Energie (2nd , 0%). Originally swb held 57.4% of the shares, of which it was able to give 8.4% to other partners. Swb has meanwhile also made use of this option and sold 5.64% to ovag Energie AG and TOBI Gaskraftwerksbeteiligungs GmbH & Co. KG. Within the company, swb took over the project management for the 30-month period of construction, among other things due to the local proximity and the associated logistical advantages, and will later also take over the operational management. At the first meeting of the consortium on March 23, the decision was made to implement the project. The general contractor for the construction of the system is a consortium made up of GE Wind Energy GmbH, GE Energy Products France SNC and Cobra Instalaciones y Servicios SA

The unofficial start of construction was on July 26, 2011, when the construction of 15 meter long and up to 80 centimeter thick reinforced concrete piles on which the power plant will be based began. A total of 1200 of these piles are being built at a rate of ten to 15 per day. The foundation stone was finally laid on November 18, 2011 .

After the completion of the power plant in the first half of 2014, the gas turbine was ignited for the first time on July 12, 2014. On December 1, 2016, the power plant was started up for regular operation.

financing

On April 23, 2009, the swb supervisory board approved the financial resources required for project planning. The investment budget for the new power plant is around 445 million euros. The WestLB assumed the position of Financial Advisor. She prepared and accompanied the financing process and the approach to banks. On June 30, 2011, GKB successfully completed the project financing with a total volume of 337 million euros by signing the contracts with a bank consortium . This acts under the leadership of Bremer Landesbank , Landesbank Baden-Württemberg and KfW IPEX-Bank ; Commerzbank , BayernLB , DekaBank Deutsche Girozentrale and Landesbank Hessen-Thüringen act as mandated lead arrangers . The terms of the contract are primarily characterized by a long term (construction time plus 18 years). The remaining funds for financing (around 108 million euros) are provided by the shareholders in the form of equity and shareholder loans. The European Investment Bank is expected to participate in the refinancing with a total volume of up to 200 million euros - this tranche is coordinated by the Landesbank Baden-Württemberg.
