Alstom has been awarded a €120 million contract by Centrica Energy for gas turbine maintenance services at the 1260MW South Humber Bank combined-cycle power plant (CCPP) in North East Lincolnshire, England. The agreement covers five Alstom GT13E2 gas turbines installed at the plant over the next seven years.
Laser Metal Deposition (LMD) could be used to reliably and cost effectively repair steam turbine and industrial gas turbine components, Roger Fairclough, Principal Engineer at TWI Ltd, told Gas to Power Journal at this year's IMechE Steam Turbine and Generator User Group in Coventry. "If the LMD process is further developed for power station applications, it will be able to produce a good useable component for steam or industrial gas turbines, making it feasible for applications where the spare part needed is not available, out of production, quite expensive or the repair is relatively small compared to the initial cost of the component," he said.
Both horizontal and vertical heat recovery steam generators (HRSG) have their own specific advantages, which makes it important for power plant operators to choose the best HRSG for their facility based on the circumstances appropriate for each type, Pascal Fontaine, CMI Energy Marketing Manager told Gas to Power Journal in an interview. In general, horizontal HRSGs are best suited for cogeneration while vertical HRSGs are best suited for combined-cycle duty although both can be used in either.
Servitization – a process where a manufacturer provides its expertise throughout the life of its product – can help CCGTs meet the challenges of a changing energy market. Alexander Bill, service manager at Alstom's Power Division underlined that "When you've got combined product design experience, manufacturing experience and service experience all in one, you can compete in different ways than an independent service provider or a third party can."
The Electric Reliability Council of Texas (ERCOT) at its March meeting on Monday approved a Weather-Sensitive Emergency Response Service pilot scheme prior to the upcoming summer that will expand its options to reduce electricity use during the peak summer season when power demand is high and supplies are tight.
The gas-fired Peterhead Project in Aberdeenshire, Scotland and the coal-fired White Rose Project in Yorkshire, England have been announced as the two preferred bidders for the UK's £1 billion Carbon Capture and Storage Commercialisation Programme Competition. The UK government will now seek to come to terms by the summer with the two preferred bidders for Front End Engineering Design (FEED) studies due to last 18 months, before a final investment decision is taken in early 2015.
Wärtsilä has launched a new product called the GasReformer for turning gas associated with the production of oil into energy. Traditionally such gases would be flared and wasted but the GasReformer uses steam reforming technology to convert gases rich in hydrocarbons into a methane rich product which can be used as fuel in gas fuelled engines.
A combined heat and power (CHP) plant being built in Düsseldorf is to achieve new records in efficiency, power, output and heat extraction. "The new CHP power plant in Lausward (Düsseldorf), starting commercial operation in 2016, will be a landmark for the future of power generation in Germany and beyond and emphasizes the role of CHP combined cycle power plants as an engine of the energy system transition," said Lothar Balling, Head of Gas Turbine Power Plant Solutions, Europe, Africa, Asia, Australia at Siemens Fossil Power Generation Division.
Utilising Smart Power Generation (SPG) technology, designed by Wartsila, can help electricity grid operators cope with intermittent power supply from renewables, which impacts markets and operations, as well as achieve cost savings, show simulations conducted by KEMA Inc. on the California Independent System Operator (CAISO).
