GE today announced it will overhaul two130-MW Siemens steam turbines at the hard coal-fired DHP Wedel Power Plant in Hamburg, Germany, owned by Vattenfall Europe Wärme AG (VE-W). The turbines were manufactured in 1963 and 1993 and are in need of maintenance to extend their useful service lives.
GE will supply the plant with technology that includes advanced steam turbine, generator, boiler, and air quality control systems to improve efficiency and lower emissions at the facility.
Each of the plant’s two units are comprised of a turboset featuring one high-pressure turbine, one intermediate-pressure turbine, and one low-pressure (LP) turbine. The upgrades will extend the operating life of the units for several years and help increase their reliability.
The turbine overhauls are part of an overall refurbishment project that Vattenfall has scheduled at the plant, which will also call on GE to deliver the valves and deliver the new LP stationary and rotating blades. Major parts of the overhaul work will be performed onsite, but the rotors will be shipped to GE’s service factory in Berlin.
The agreement builds on GE’s 25 years of servicing generation equipment at various Vattenfall power plants throughout Germany. GE enhanced its capabilities to service power equipment made by other manufacturers following the acquisition of Alstom Power in November 2015.
“We are excited to work with Vattenfall to demonstrate our enhanced capabilities to service other manufacturers’ turbosets by providing a customized package to meet Vattenfall’s efficiency and reliability requirements and demonstrate how GE’s coal-generation portfolio is well-positioned to respond to the region’s future energy needs,” said Pascal Schweitzer, general manager of GE’s Power Services business in Europe.
The project will commence in 2017.
