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.
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.
MAN Diesel & Turbo has launched the 35/44G engine as its latest addition to its four-stroke power portfolio. With an electrical efficiency of 47.2 percent, the newly developed Otto gas engine is available for Combined Heat & Power (CHP) or can be installed in a combined cycle mode jointly with an MAN steam turbine of the MARC series.
The resemblance between Montana, a state in north-western United States and European countries like Spain, Denmark or Germany is striking.
"What we are seeing in Montana and also here in Europe is that our FT8 SWIFTPAC aeroderivative gas turbines are being used to maintain adequate power flows in the grid to counterbalance fluctuating wind energy," says Swift Tarbell, Pratt & Whitney Power Systems Area Director for Europe.
