If the rotating equipment and boiler are a plant’s brawn, then a control system that efficiently integrates myriad plant functions is its brains. Luckily, in a power plant, we can perform a brain transplant when the control system becomes unreliable or too costly to maintain. But first, you have to justify that surgery.

Wind power is becoming a mainstream energy source that U.S. utilities are tapping into nationwide as a means of adding clean, domestically sourced energy to balance their generating portfolios. To identify where wind will take us,POWER’s senior editor talked to experts from diverse industry stakeholders about current and future developments.

The Steel Winds project in Lackawanna, New York, was selected as a POWER 2007 Top Plant because of its unusual location (a former steel mill and Superfund site) and because it was the first commercial deployment of the Clipper Windpower 2.5-MW turbine. That report was written just as the project entered commercial service but before a major gearbox problem was identified. For many new designs, it isn’t a question of if problems will occur but of how the manufacturer responds when problems inevitably do occur. For its handling of Liberty’s problem, Clipper Windpower gets an "A."

Call it the "trillion dollar conundrum." Really big money is needed to equip the U.S. transmission system to handle a variety of new requirements and increased load, but it isn’t clear how to raise it, spend it, or recover it. Expect new renewables projects to die on the vine until the gridlock loosens.

Advanced computer design tools have merged with high-definition laser camera scan data to produce integrated images that are particularly useful for outage and maintenance planning.

As an alternative to titanium, consider highly alloyed stainless steels for your next tubing project.

Eskom’s cautionary tale should remind those involved in the power industry anywhere in the world that past performance is not a guarantee of future success.

A key maxim of the military is "train like you fight, and fight like you train." The same applies to emergency response training, which should be a part of a plant’s routine operation. Don’t risk waiting until an accident occurs to test your response plan. At approximately 8:30 a.m. on a Tuesday morning, the Paducah […]

Do you have enough women working in your power plant? Forget for a moment equal opportunity laws. More important is the knowledge that the programs and culture changes that would make women more likely to consider a plant career are the same ones that would make it more attractive to many younger men.
