The Knapsack II gas-fired combined cycle power plant has been completed in Germany six weeks ahead of schedule.

The power plant located in Hürth near Cologne, Germany, was built by Siemens for Statkraft Markets GmbH, a subsidiary of the Norwegian utility company Statkraft, has a capacity of 430 MW and an efficiency of 59.2 per cent. Siemens say the plant is among the most environmentally friendly in Europe.

The project included installation of an F-Class gas turbine as well as a steam turbine, generator, and heat recovery steam generator. In a statement Siemens said that the short run-up and shutdown times make the power plant ideally suited to compensate for the fluctuating feed-in of renewables, ideally suited to Germany’s current energy policy direction.

“Due to its high efficiency, the CO2 and nitrogen oxide emissions are very low. In addition, when in hot-start mode, the power plant can be run up to full load in just a few minutes and thereby compensate for fluctuations in electricity generated by wind turbines and solar stations. Flexible and reliable CC plants such as Knapsack II are necessary to support the new energy policy. However, it does have to adapt to market conditions in order to ensure that the investments are amortized over time,” said Lothar Balling, the head of Gas Turbine Power Plant Solutions at Siemens Energy.
