O&M AND UPGRADE??
GE signs $116 service alliance with TVA...1 August 2010
GE has signed a five-year service alliance with the Tennessee Valley Authority (TVA) covering four power plants and valued at $116 million.
Under the agreement, GE will provide service support for the next 24 planned outages at TVA’s Brown’s Ferry nuclear plant and the Paradise, Bull Run and Widow’s Creek fossil-fired plants. GE Energy Services will provide a core team that will provide expertise and experience on site at the various plant locations to help TVA manage the outages and respond quickly to specific project requirements. A team of senior managers from both companies will oversee the implementation of the five-year alliance.
GE says the alliance is “designed to create an environment in which both parties work together like one entity to meet the strategic needs of TVA”, the two companies’ “mutual mission” being “to improve TVA’s turbine-generator fleet performance through risk/ reward sharing, improving and innovating processes, utilising new technology and optimising outages.”
...and aims to reduce NOx at Little Barford
The first UK installation of GE’s dual fuel DLN2.6+ combustion system, which can reduce NOx emissions by 40%, will be on two 9F gas turbines at RWE npower’s Little Barford 680 MWe combined cycle plant (pictured right).
The installation will be part of a project contracted to GE to reduce emissions, improve efficiency and extend the life of the plant, which is near St Neots, Cambridgeshire. The contract includes a six-year “maintenance support agreement”.
The DLN2.6+ technology allows the gas turbines to be operated at reduced power during off-peak periods while maintaining low emissions levels. This saves fuel and leads to reduced operating costs. DLN2.6+ technology is already in use at power plants elsewhere in Europe, notably in Italy, where emissions regulations are particularly stringent, says GE.
The uprated 9F gas turbines are scheduled to be in commercial operation by the third quarter of 2012. The station’s gas turbine control system will also be upgraded, with a GE Mark VIe control system.
