The joint power station in Kiel (GKK) was operated jointly by Uniper and Stadtwerke Kiel . The coal -fired power station, which is fired with imported hard coal, generated electricity and supplied more than 60,000 households with district heating . In 2019 the power plant was shut down and replaced by the modular gas engine power plant KIEL built directly next to it .

history

In 1965, the Stadtwerke Kiel developed plans for a new power plant with an output of 100 MW. Since new power plants should have at least 300 MW according to a law, the municipal utilities cooperated with Nordwestdeutsche Kraftwerke AG , which also wanted to build a new power plant. For this purpose, an operating company was founded, the Gemeinschaftskraftwerk Kiel GmbH, in which Nordwestdeutsche Kraftwerke AG held two thirds and Stadtwerke Kiel AG held one third. In 1987 there was a change in the ownership structure. PreussenElektra , in which the Nordwestdeutsche Kraftwerke AG had now merged, sold part of its stake to the Stadtwerke Kiel, so that both partners now held 50% of the power plant. In 2000, PreussenElektra with Bayernwerk AG merged, whose share went to the newly founded company from E.ON on. In 1990 the Kiel district heating tunnel on the other side of the Kiel Fjord was completed, in which two district heating pipes with a diameter of 700 mm run.

technology

The power plant had a gross output of 354  MW , the net output was 323 MW. In addition, up to 295 MW th could be extracted as district heating. This was done by branching off steam before flowing through the low-pressure turbine and channeling it into heat exchangers , in which the heating water was heated to a temperature of 130 ° C. After several modernizations, the electrical efficiency of the power plant was most recently around 39.5%; the overall efficiency including the district heating extraction was a little over 50%. At full load , around 110 tons of hard coal were burned per hour. The grid connection was made at the highest voltage level (220 kV) in the power grid of TenneT TSO , formerly E.ON Netz GmbH.

Replacement building

In spring 2019, the joint power plant was shut down and is to be replaced by a modular gas power plant currently under construction called the coastal power plant . The gas power plant consists of 20 combined heat and power operated gas engines with a total of 190 MW electrical output. In addition, 190 MW of district heating can be extracted. Overall, a fuel utilization rate of more than 90% is possible, with which the carbon dioxide emissions can be reduced by 70% compared to the coal-fired joint power plant. Due to the design, the power plant can be operated very flexibly: Each of the gas engines can be individually controlled and can reach its nominal output within 5 minutes , while the original coal-fired power plant required at least 4 hours to ramp up to nominal output. The new power plant is supplemented by a district heating storage system with a capacity of 30,000 cubic meters and a power-to-heat system, which enable additional flexibility in operation by decoupling power generation and heat supply. The total cost of the new building is given as 290 million euros.
