Now that the 412-MW Timelkam Power Plant has replaced a 47-year-old coal-fired power plant located in the Vöcklabruck District, northern Austrians can bid auf wiedersehen (goodbye) to high levels of air pollution. Compared to its predecessor, the new gas-fired combined-cycle plant has dramatically cut CO2 and NOx emissions and produces seven times more energy.
There’s nothing slow about the fast-track operations at the new 870-MW Sloe Centrale Power Plant. The combined-cycle plant is designed for 250 starts per year and is capable of supplying power to the grid within a mere 30 to 40 minutes. In addition to its impressive rapid load response, the gas-fired plant produces low CO2 and NOx emissions by using the latest technology. It also attains an efficiency of 59%.
At the Ras Laffan Power Co. facility, the 756-MW net combined-cycle plant and the integrated 40 million gallons per day desalination plant are working in tandem to provide abundant, reliable electricity and desalinated water to residents of the State of Qatar, the most prosperous nation in the Middle East.
The Panoche Energy Center is a 400-MW simple-cycle power plant using four of General Electric’s GE LMS100s with fast-start capability. Dispatched by Pacific Gas & Electric to meet regional power and grid stabilization needs, the project entered commercial service two months earlier than planned. Panoche is the largest LMS100 peaking facility in the U.S.
The UK grid, focused on adding valuable renewable generation, will rely on natural gas–fired generation for many years to come. One of the most recent additions is the Langage Power Plant, designed for quick response and low load “parking” at night while remaining below air emissions limits. With an extraordinary architectural design that blends into the natural surroundings, Langage is now a local landmark.
We first reported on combined-cycle plant reliability concerns due to erosive wear and flow accelerated corrosion (FAC) in heat-recovery steam generator (HRSG) pressure parts at the 1999 EPRI Maintenance Conference. More than 10 years later, these damage mechanisms remain significant contributors to forced outages, pressure part repairs, and major component replacement.

GE launched what it is calling the world’s first two-stage turbocharged gas engine this June.
In 2010, U.S. wind power development has slowed, coal-fired power development remained stalled, and the much-awaited renaissance of nuclear power took a few tentative steps forward. That left natural gas power development as the last man standing.
