The California Energy Commission (CEC) recently awarded about $14 million for carbon sequestration projects to be overseen by the West Coast Regional Carbon Sequestration Partnership. Westcarb, as the partnership is known, is part of the U.S. DOE’s effort to deploy technologies through its Regional Carbon Sequestration Partnership (RCSP) program. New members Alberta and British Columbia […]

Calpine Corp.’s South Point Energy Center in Mohave County, Ariz. (Figure 1) is a 520-MW natural gas-fired, combined-cycle facility with two Siemens Westinghouse 501FD gas turbines and one steam turbine-generator with a BB33 high-pressure (HP) section, a BB65 intermediate-pressure section (IP), and a 65CC intermediate/low-pressure (LP) section. The plant entered commercial service in June 2001. […]

The 1,768-MW Baldwin Energy Complex in Illinois was the site of a joint-venture pilot project to demonstrate a wireless vibration-monitoring system for a coal pulverizer. The partners in the project were EPRI and the plant’s owner, Houston-based Dynegy Midwest Generation. A key objective of the project was to identify a reliable wireless system capable of […]

Stretching meager maintenance dollars is a way of life for most maintenance staff. In past years, the cost of an infrared (IR) camera usually came down to a choice between a low-resolution 160 x 120-pixel camera or no camera at all. If the camera was chosen, it usually became clear before long that low resolution […]

The U.S. needs new generating capacity in coming decades to meet growing electricity demand. The increasing scarcity of land within utility load centers, combined with environmental opposition to the siting of plants, often limits siting options to remote locations. Restricting power plants to distant sites necessitates additional transmission facilities, increases delivery costs and electric bills, […]

An essential ingredient in the success of any business endeavor is thorough planning. We’ve all heard the axiom "proper prior planning prevents poor performance" or a variation on that theme. Why the need for peak performance? Competition within the industry has never been as intense, with utilities combining in search of economies of scale. The […]

In 1500, Leonardo Da Vinci drew sketches of a device that rotated when hot air going up a chimney passed through a set of fan-like blades. Leonardo called his invention a "chimney jack," and although it only turned a roasting skewer, it gave birth to the idea of mounting blades on a shaft to convert […]

There’s a relatively easy way to make a steam plant more efficient and reliable: keep the tubes of its condenser(s) clean. According to George Saxon, Jr., VP of international sales and marketing for Conco Systems Inc. (Verona, Pa.)—a company whose specialty is cleaning and maintaining condenser tubes—"There are two major problems that result from dirty […]

Remember the slogan, "Never trust anyone over thirty?" Chances are you’ve joined the ranks of the over-thirty generation and are dealing with your own personal "maintenance" issues—not unlike the fleet of generators at larger U.S. power plants, whose average age is about 30. Given the continuing growth in U.S. electricity demand and the cost and […]

Age is wreaking havoc on the U.S. generation industry, especially the coal-fired sector. Industry conferences are replete with hand-wringing over the "brain drain," the lack of skilled personnel, the meager number of students pursuing engineering degrees, and the accelerated retirement of the older workers who make up the industry’s experience base. On top of this, […]
