In the face of a global trend toward a green energy, efficient use of natural gas at peaking plants play a central role in ensuring security of electricity supply, says Dietmar Siersdorfer, chief executive, energy at Siemens Middle East. Peak-load gas turbines upgraded with Wet Compression technology can produce up to 15 percent more electricity output, he said, and take better advantage from high peak load electricity prices.
Hit by persistently low spark spreads, SSE has decided to halt operations at its ageing gas-fired combined cycle power stations at Keadby (760 MW) and Medway (688 MW) for a comprehensive maintenance programme aimed at enhancing the plants' operational flexibility from March 2013 onwards.
Shanghai's largest cogeneration facility, the Caojing plant will host GE's first Dry Low NOx (DLN) 2.6+ combustion system upgrade for an installed 9FA 3-series gas turbine in Asia. GE said the equipment for the first DLN 2.6+ upgrade will be shipped in October 2013, with schipment for the second upgrade due in January 2015.
Europe's ailing recovery and decreasing gas-to-power demand, in competition with coal and renewable energies, is forecast to put a lid on LNG demand for years to come, analysis from PIRA Energy Group shows.
Shell aims for a growing engine oils segment by launching a new sour-gas compatible lubricating oil. "There could be a 10% sales growth in the stationary gas engine oils segment this year," Richard Holdsworth, Global Brand Manager for Shell Power Lubricants told Gas to Power Journal.
E.on, Germany's biggest utility by revenues, is considering the part-closure of one of Europe's most modern gas-fired power stations in Irsching, Bavaria. Dr. Johannes Teyseen, E.on chief executive, said "the rapid growth of renewables has made gas-fired plants largely uneconomic to operate".
China's electricity production has surged more than 200% since 2000, spurring the nation's hunger for coal – the primary fuel for power generation. Coal consumption in China now accounts for 47% of global coal consumption – nearly as much as the entire rest of the world combined.
Ratnagiri Gas & Power Private Ltd (RGPPL) in India is limping back to producing electricity at its Dahbol power plant (1,967 MW) after being forced to shut down operations due to an acute shortage of gas to run the plant.
Tensaka Energy, an US-based power plant developer and energy marketer, has joined forces with the Brownsville Public Utilities Board (BPUB) to build an 800 MW gas-fired combined-cycle power station in Brownsville, Texas. "With increased scarcity pricing and decreased operating reserves in ERCOT [Electric Reliability Council of Texas], the project is well positioned for success," Tensaka Energy said.
Energy services giant Wood Group GTS has signed a four-year operations and maintenance (O&M) contract with Entegra Power Group and Sundevil Power Holdings for the 2,200 MW Gila River gas-fired power plant in Arizona, U.S.
Tightened safety rules and maintenance of Japan's two operational reactors could lead to a complete nuclear shutdown by summer for the second time since the Fukushima disaster in March 2011. Power producers, required to avert power shortages, are hard-pressed to import even more highly priced LNG to fuel backup gas-fired power plants, analysts warn.
Thailand's Eastern Power and Electric Co. Ltd (EPEC) has signed a 10-year operations and maintenance (O&M) contract worth €90 million with Alstom to service and upgrade its Bang Bo power plant with MXL2 turbine blade and components.
