It’s easy to forget about the “big box” selective catalytic reduction (SCR) unit sandwiched in your HRSG modules, even though it stands between you and compliance with your air permit, and your ability to operate. At the 2017 conference of the Combined Cycle Users Group (CCUG), held in Phoenix the last week of August, Andy […]

Natural-gas fuel composition has considerable influence on gas-turbine emissions and operability. This might not have been a concern to you previously, but the possible impacts on your engines of increasing reliance on non-traditional pipeline gas—in particular, shale gas, but also LNG, and byproduct fuels from industrial processes—suggests you might want to read on. Even if

When Paul White crossed over to the spiritual world from the physical Nov 16, 2017, he was well prepared for the journey and certainly was welcomed by those who had preceded him. White was a deeply religious man who taught Sunday school and gave church activities his full support—all while excelling in his engineering day

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

What’s happening inside the fast-growing, hugely profitable, digital behemoths—one characterization is the “Big Five,” namely, Amazon, Apple, Facebook, Google, and Microsoft—may be more important than what the electricity industry sees from the outside. We know they are driving the industry towards renewable energy through direct investments in solar and wind facilities and green electricity purchases.

Once upon a time, a vertically integrated utility was responsible for electricity supply—soup to nuts, that is, from the powerplant to the customer’s meter. Today, responsibility for over half of US power production rests with non-utility entities. Like most big industry shifts, this transition has led to greater efficiencies in some areas, challenges in others.
