Siemens transports largest gas turbine

Energy efficiency

The largest, most powerful, and most efficient heavy-duty gas turbine that Siemens has produced to date was loaded onto an inland cargo ship today in Berlin, where it set off on its journey for Keadby, Lincolnshire, in the UK to be tested in a power plant of UK energy generator SSE Thermal.

Built by Siemens Gas and Power in its Berlin factory and destined for the 50-Hertz market, the powerhouse known as SGT5-9000HL measures 13 meters in length, five meters in height, five meters in width, and weighs nearly 500 metric tons. After the recent first fire and synchronization to the grid of its first 60-Hertz version in a power plant in the United States, Siemens reports this second milestone for its latest HL-class within several weeks.

High efficiciency

To test the 50-Hertz version of the HL-class machines, Siemens is building the Keadby 2 power plant for SSE Thermal. With its 593-megawatt (MW) capacity, the gas turbine sets new standards in power, efficiency, lifecycle costs, and operating flexibility. After the test phase, the gas turbine system will be expanded into a highly efficient combined cycle power plant, where the turbine will then rise to a new level of maximum performance: 840 MW and a baseload efficiency of more than 63 percent. The higher efficiency will save fuel and simultaneously reduce CO2 emissions in Keadby by as much as 3.7 million metric tons per year, compared to coal-fired power plants.

Transport

The turbine will first travel by inland waterways, heading west to the Port of Rotterdam in the Netherlands, where it will be loaded onto a coastal ship for transport to the eastern coast of England. It will travel up the Humber and Trent rivers for approximately 12 days until it reaches the inland port of Keadby, where it will be lifted off the ship and driven to the construction site.

Remote monitoring

Initial operation of the new turbine in Keadby is scheduled for 2021. SSE Thermal will place the turbine into commercial operation in 2022, following successful testing. In addition to the technology, Siemens is also providing service with its first long-term program (LTP) for an HL-class gas turbine in Europe. Siemens will utilize its advanced digital service solutions, including remote monitoring and diagnostics, to help maintain the availability, reliability and optimal performance of the power plant.
