The most efficient powerplants ever produced are now entering service. These latest and largest combined cycles—powered by GE’s 7HA, Siemens’ SGT6-8000H, and Mitsubishi Hitachi’s M501J engines—are all clocking in at 62% – 63% thermal efficiency. This makes them the most efficient heat engines yet perfected by engineers, with all three OEMs striving to reach 65% …
There are nearly as many electric generators at fossil-fired and nuclear powerplants as there are gas and steam turbines combined. So, you might think that with thousands of utility/large industrial-grade generators rated more than 25 MW operating in the US alone, the annual meeting of the Generator Users Group (GUG) would draw hundreds of attendees. …

Commissioning seven gas-turbine (GT) control systems in seven weeks would probably be taxing under the best of conditions. In NV Energy’s case, there were some extenuating circumstances. First, the seven systems are located at two generating facilities acquired by the utility in 2014. Second, it is challenging to test a retrofit, due to air permit …
