Future gas turbine research and development (R&D) needs to focus on a 'big is beautiful' approach to developing smaller, flexible units that can run efficiently at part-load, OEM representatives from Alstom, GE, Mitsubishi HI, Siemens and Pratt & Whitney Power Systems agreed at a conference in Brussels today.
Singapore is building three new large combined cycle plants to cater for the city state's growing electricity demand.
"The selection of combined cycle plants based on GT26 advanced gas turbines for all three of these projects indicates the importance of high plant flexibility while maintaining high efficiency and low emissions in many of today's electricity markets," says Pascal Radue, regional vice president, Alstom Gas Business, Asia.
GE will supply eight gas turbine-generators for the expansion of Saudi Electricity Company's (SEC) Riyadh Power Plant 12 (PP12). Once operational in 2015, the combined-cycle plant will be the first application of GE's 7F-5 series gas turbine technology in Saudi Arabia, adding nearly 2,000 megawatts of electricity to help meet the Kingdom's future energy demand.
RWE's decision as to which gas turbine vendor to use for its newly opened Pembroke Power Station has been largely driven by Alstom's service agreement, according to Andy Smith, project development manager at RWE.
"In the UK, the market for building new combined-cycle plants is EPC-based and we were therefore exposed to the equipment choices that the different turbine manufacturers have on offer," he told Gas to Power Journal at a conference organised by the publication in London.
Aggreko, a leading provider of temporary power generation services, has opened its first service centre in Walvis Bay, Namibia, to meet to power demand of the country's rapidly growing mining industry. Located next to the Port of Walvis Bay, the facility is also well positioned to supply backup power generation to Namibia's shipping and fishing industries.
Alstom has developed a MXL2 upgrade for GT26 gas turbines, offering power plant operators to adapt production hours of their plants to fluctuating demand and to significantly extend inspection intervals and increase availability – key features in markets with a large share of intermittent wind generation such as Spain, says Leone Tessarini, product manager at Alstom's gas turbine services.
