Port Westward Generating Plant, Clatskanie, Oregon

Since going commercial this June, Port Westward Generating Plant has taken its rightful place as one of America’s most efficient power stations. It is now helping to satisfy Portland General Electric’s summer demand reliably and cost-effectively. What differentiates Port Westward is its pioneering use in the U.S. of Mitsubishi Heavy Industries’ G1 class combined-cycle combustion turbine.


Port Arthur II Integrated Hydrogen/Cogeneration Facility, Port Arthur, Texas

The rationale for a typical cogeneration plant is clear: Supply some power, and maybe some steam, to an industrial host and save energy dollars on both sides of the fence. But integrating a cogen plant that also produces hydrogen with a major refinery that operates 24/7 is a job best left to a company with diverse and proven technology skills. The Air Products Port Arthur II project proves that such a job can be done right. Accordingly, it is one of POWER’s natural gas–fired Top Plants of 2007.


Detecting and solving lube oil varnish problems

Have you bought electrostatic or agglomeration equipment to rid your turbine oil of varnish deposits, but its varnish potential rating failed to improve? Or, after an initial drop, has the varnish potential returned to its previous level? Even worse, have you had recurring valve sticking problems after making a sizeable investment to "solve" this problem? Welcome to the world of soluble varnish caused by autodegradation. Read the unvarnished truth about varnish and how to get rid of it for good.

Siemens G-Class technology builds for the future

Gas turbine manufacturers aren’t selling as many machines today as they did in the hyperactive 1990s. But they are still continuing to refine G-Class technology. It has been about eight years since the first steam-cooled SGT6-6000G from Siemens Power Generation entered service. Take a quick tour of what must now be considered a mature gas turbine technology.

Will turbines require expensive retrofits to handle imported LNG?

With domestic reserves of natural gas declining and demand for gas rising, imported liquefied natural gas will increasingly fill the shortfall in U.S. pipeline supply. More than 40 LNG receiving/regasification terminals on three coasts are in various stages of development. Yet many questions about the operational and emissions impacts of the "hotter" LNG imports on today’s cleaner-burning gas turbines remain unanswered.
