Leaders in the utilities sector talk a lot these days about talent. On one hand, they express concern about facing a shortage of knowledgeable staff as 76 million baby boomers exit the workforce. On the other, they worry about where they’ll find enough qualified people to remain competitive in light of the fierce battle for engineering talent that globalization has created. The antidote to these worries lies in reconfiguring HR practices.

New CIP standards leave questions unanswered/Solving common analyzer problems/Qualifying rebuild shops

Even comedian Rodney Dangerfield got more respect than many plant water sample panels do. But power plants ignore sample panels at their peril. Those sample panels, and readings of the on-line analyzers they support, identify when multi-million-dollar systems have a problem that demands immediate attention.

Hot reheat steam bypass actuators are some of the most critical, yet least understood components in a typical combined-cycle plant. If you’re using pneumatic actuators to stroke your main steam or hot reheat bypass valves in a cascading bypass system, you’re behind the times. Here’s a way to get better control of the bypass process, shorten unit start-up and train blending times, and decrease your plant’s heat rate—all at the same time.

Predicting combined-cycle system longevity and determining optimal maintenance intervals at the same time is difficult: It requires balancing repair costs against the risk of trying to squeeze that last bit of life out of some component before it fails. One solution to the problem is to extend coverage of an equivalent operating hours (EOH) preventive management program for turbines to the entire plant.

Shawnee’s new 1,093-day long-run record is a testament to the plant’s highly qualified and trained staff, excellent operations and maintenance processes, and the quality leadership required to keep all the moving parts pointed in the right direction. If running a power plant is a team sport, then the staff of Shawnee are in a league of their own.

The Fossil Productivity Committee of the EUCG conducts an annual analysis of its member plants’ operating results and selects the Best Performer in the categories of small and large coal plants. For 2007, Alliant Energy’s Lansing and Edgewater Generating Stations took the top spots—the first time in recent history that a single utility claimed both awards.

POWER has reported on several EUCG benchmarking studies over the past several years. This month we examine the maintenance staffing of 45 coal plants reported by 13 EUCG member utilities. If you benchmark your plants or fleet, as you should, some of the study’s results challenge what is considered conventional wisdom.
