Modern predictive maintenance systems can monitor the health of most plant equipment. By sorting through the wealth of information those systems deliver, operators can discern important trends, including the early signs of a system or component failure.

The next-generation power grid—enhanced by digital technologies throughout the network to give generators, distributors, and customers greater control—promises to improve efficiency and lower operating costs. This year, in the most full-scale effort yet, Xcel Energy begins introducing intelligent grid technologies that it hopes will make Boulder, Colo., the first Smart Grid City.

The idea of harnessing the vast power of Earth’s oceans has tantalized humans for more than a century. Today, the prospect of generating as much as 4,000 TW of clean energy from marine sources is fueling a resurgence of interest in a variety of technologies.

In mid-2006, a Google search of the term “Smart Grid” generated around 2,000 responses. The same search this past month yielded more than 500,000 hits from a wide variety of sources. The explosiveness of the concept is especially interesting because there is no universal agreement on what constitutes a smart grid—much less agreement on what […]

Selecting the right turbine(s) for a specific power project is a complex process that poses two challenges. One is understanding which field experience cited by suppliers represents proven technology; the other is evaluating whether a turbine upgrade represents an evolutionary change or a revolutionary transformation that warrants further study before deploying it in the field. Here‘s how a leading EPC contractor makes technology-neutral equipment selection decisions on behalf of its customers.

Managing ongoing threats to power plants’ digital, telecommunications, monitoring, control, and automation systems is no longer just a good idea. It’s an essential element of superior plant operations and now a regulatory requirement as well, thanks to new critical infrastructure protection standards recently approved by FERC.

The new, 424-MW Castejon 2 combined-cycle plant designed and built by Alstom was recently given its provisional acceptance certificate. Alstom used its “Plant Integrator” approach to fast-track delivery of a plant just like Castejon 1, which averaged 98% availability during its first three years of operation. That kind of performance is crucial to generators operating in the Spanish merchant power market—or any market.

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.

If you enjoy POWER magazine’s New Products department, you’re going to love the ELECTRIC POWER 2008 Exhibition. You’ll be able to see and feel the latest tools of the trade and talk to the folks who provide them to the generation industry. Here’s a sneak peak at what awaits you on the exhibit floor May 6 to 8 at the Baltimore Convention Center.

  North America’s electricity grid has been described as the world’s most complex machine. The grid is unique among utility infrastructure systems for its need to have supply and demand—generation and load—balanced at all times. There still are no technologies for storing large quantities of electricity akin to liquefied natural gas tanks, voice mail, or […]
