Earlier this year, a new combined-cycle gas turbine (CCGT) power plant, nicknamed “Fortuna”, located in in the Lausward district of Düsseldorf, Germany, went live and was handed over to Stadtwerke Düsseldorf AG, the municipal utility company.
As a result of going live, the facility set three energy output world records: a maximum electrical net output of 603.8 megawatts (MW); a net power-generating efficiency rating of approximately 61.5%, which beat the old record of 60.75%, also held by Siemens, at a power plant in Irsching, Germany; and the capability to deliver up to 300MW for the district heating system of the city of Düsseldorf, an international peak value for a power plant equipped with only one gas and steam turbine.
The high efficiency level boosts fuel utilization up to 85%, while reducing CO2 emissions to a mere 230 grams per kilowatt-hour, which are the result of innovative developments in the design of components, materials used, and the overall construction of the facility. The gas turbine can run at full load in less than 25 minutes after a hot start, enabling it to also be used as a backup for renewables-based power production.
Because of the plant’s close proximity to the downtown area, special importance was attached to minimum emissions and lowest achievable noise levels. Of particular importance to risk managers, the project was successful with regard to occupational safety. More than two million man-hours of work were put into the plant’s construction without a single accident. AGCS was lead insurer on this monumental project.
Facts & Figures
- Combined-cycle – A gas turbine generator generates electricity while waste heat from the gas turbine is used for steam to generate additional electricity via a steam turbine.
- 61.5% efficiency – A natural-gas-fired combined-cycle power plant such as this one, with an electrical efficiency of 61.5%, theoretically saves approximately 2.5 million tons of carbon dioxide (CO2) annually. This corresponds to the amount of CO2 emitted by 1.25 million passenger cars, each driving 15,000 kilometers a year.
- CO2 – Reduction of 2.5 million tons per year
- 600,000 – Number of Düsseldorf residents who will be supplied with heat and electricity from the plant
- 25 dB – Noise exposure in the urban area: normal conversation is about 60 dB (the plant is in the bustling Rhine River harbor area of Düsseldorf, in the heart of the city)
- 25 minutes – Amount of time after a hot start till the plant is operating at full capacity
- 78 – Number of contracts to date of similar facilities to be built by Siemens
