Alstom to build, service gas-fired combined heat and power plants in Germany

Sponsored by

Alstom has signed a contract with the German utility, RheinEnergie, for the turnkey construction of a 450 MW combined-cycle heat and power plant in Cologne, Germany. In addition, Alstom has also signed a 15-year service agreement for the plant. In total, RheinEnergie is investing about $457 million into the project.

The new power plant is part of Germany's energy turnaround program, which includes the building of combined heat and power plants. The Niehl 3 CHP power plant will be based on Alstom's gas-fired KA26 combined-cycle plant design.

The project includes the delivery of one GT26 gas turbine, one steam turbine, the turbo-generator, heat recovery steam generator and district heaters as well as power plant control systems. Commissioning of the power plant is scheduled for 2016.

The plant will reach an overall efficiency of close to 85 percent. Niehl 3 will provide electricity to the local and European grids. The plant has the potential to supply up to one million households with energy.

By providing up to 265 MW thermal heats, enough to heat 50,000 homes, the plant will reinforce the district heating networks of Cologne. In addition Niehl 3 will save about 500,000 tons of carbon dioxide per year compared to the average emissions emitted by German heating installations with a similar thermal heat output.

Alstom technology powers close to 10 GW-worth of gas-fired power plants in Germany. Nearly half this capacity has been built as combined heat and power plants including the recently constructed 876 MW Emsland power plant for RWE and the 385 MW Berlin Mitte power plant for Vattenfall which, at the time of initial operation in 1997, was already one of the most modern and efficient CHP plants in the world.

Gas-fired power plants support grid stability with fast start-up times and high efficiencies even at low load. Alstom's KA26 combined cycle power plant achieves efficiencies of over 60 percent and can be started up in less than 30 minutes. Fully synchronised with the grid, the plant can reliably feed 350 MW into the grid from low-load operation in less than 15 minutes. Close to 70 gas-fired power plants based on the KA24/KA26 technology are in operation or under construction worldwide.

The contract will be executed in two phases. The first is effective immediately and covers the preparation and support of RheinEnergie's construction permit planning process. The second phase will be effective after the full notice to proceed, expected in the third or fourth quarter of Alstom's fiscal year 2013/14.
