Sixty percent efficiency! Like breaking the sound barrier, running the four-minute mile or the search for the Holy Grail, many of the big gas turbine original equipment manufacturers (OEMs) are [...]

Combined cycle plants give greater output for the same amount of energy and emissions. But this comes at a cost--increased complexity of design and operations. Optimizing a combined cycle plant [...]

When people are under pressure, it's a good idea for them to take a break and let off a little steam; it's unhealthy to keep things bottled up inside. With [...]

One small part of the Energy Policy Act could send power industry firms scrambling to get their houses in order. Among the 500 ponderous pages of the Act sits the [...]

The movie 'Space Cowboys' showcases Clint Eastwood, James Garner, Donald Sutherland and Tommy Lee Jones as aging engineers, technicians and former spacemen who are called upon to rescue a falling [...]

Dedicated in May 2004, the 162 MW Colorado Green Wind Project's 108 wind turbines are producing more than renewable electricity on the rural plains of southeastern Colorado. Located in Prowers [...]

At one of the world's largest power companies, all purchasing was once executed locally. When the economy tanked, the power company set up a task force to reduce the plant's [...]

The debate over stainless steel versus plastic in coal handling equipment such as bunkers, silos, hoppers and railcars has persisted for decades. Plastic advocates cite impressive numbers about coal flow, [...]

The deregulated electric power market is still a work in progress, and will be for some years to come. Like claim jumpers in a gold rash town, a few tried [...]

The extension of the federal Production Tax Credit (PTC) in 2001 fueled the development of the largest new crop of wind farms ever seen in U.S. history. Larger plants such [...]

Through an ongoing series of customized adjustments to boost efficiency--ranging from inlet fogging and interstage injection to new inlet filters and turbine blade tips--the Watson Cogeneration Plant in Carson, Calif., [...]

Offshore windfarms are all the rage in Europe. Denmark, Holland, Sweden, and the United Kingdom have large offshore farms up and running, with many more in the pipeline. Ireland, Belgium, [...]

El Paso Energy Corp.'s Field Services unit has successfully harnessed fog-based, evaporative cooling to gather as much as 18% more gas for its Chaco cryogenic processing plant in New Mexico. [...]

Is evaporative cooling of gas turbines only suited for hot dry areas of California, Nevada and Arizona and not in humid areas of Florida or the colder climates of the [...]

OVER THE PAST FEW YEARS, HIGH-PRESSURE FOG COOLING UNITS FOR POWER AUGMENTATION HAVE BEEN successfully installed in hundreds of turbines throughout North America and around the world. Not surprisingly, major [...]

Temperature control is a big deal in Pittsburg, Texas, where summer afternoons average in the mid-90s and frequently top 100. At AEP/ SWEPCO's J. Robert Welsh Power Plant, however, the [...]

Retrofitting turbines with lighter, thinner blades can boost power output. While many believe in the slogan 'you can never be too thin or too rich,' some engineers have been reluctant [...]

Gas-electric hybrid engines are gaining popularity as a way to boost fuel efficiency. Automotive fuel producers are also adopting a hybrid approach to improve the efficiency of their plants--using combined [...]

Operating a boiler is a careful balancing act, matching the fuel, airflow and draft pressure throughout a wide range of load conditions. As plants are being called on to operate [...]

Heat recovery steam generators (HRSGs) are an excellent way to capture more value from the fuel budget. But achieving the most from an HRSG requires that they be operated as [...]

The Steel Winds project launched in the middle of 2007 under a blaze of publicity. What made it so newsworthy was that it was among the first urban wind farms [...]

In late 2006, the first Liberty wind turbines rolled off'the assembly line at Clipper Windpower's Cedar Rapids manufacturing plant. By 2008, Clipper had ramped up production to about 300 turbines, [...]

Distributed generation offers the opportunity to deliver the power where it is needed without adding to the transmission network load. When coupled with cogeneration, it also boosts energy efficiency and [...]

Adistinct trend is emerging in the manufacture of wind turbine generators--the use of permanent magnets (PM). At the American Wind Energy Association's Global Windpower2007 Conference and Exhibition held in Los [...]

A member of the Association of Storage Networking Professionals (www.asnp.org.) who manages storage for a large North American retailer gathered the information in this case study. Due to rapid growth, […]

Once upon a time, they say, doctors made house calls, arriving, black bag in hand, to take your temperature and dispense needed pills. Today, the visiting doctor is as elusive [...]

Poised to become part of the energy mainstream, wind faces one of its most difficult challenges to date: Scaling output up to the level required by utilities. While it took [...]

Public policy and transmission access issues dominated the program as the wind industry showcased its march into the energy mainstream to 3,500 attendees and 225 exhibitors at Global Windpower 2004 [...]

Over the past five years Europe pioneered the development of offshore wind farms, establishing 13 small offshore plants in Sweden, Denmark, Holland and UK. In 2002, the 160 MW Horns [...]

With more and more utilities introducing wind into their power mix, manufacturers are being pressured to meet more stringent transmission standards. A recent advance in power electronics known as Low-Voltage [...]
