Duke and Southern Indiana Gas and Electric Company […]

By Kennedy Maize   Evidence builds for the proposition that constructing new high-voltage transmission remains harder than bringing on new power generation. Facing increasing political opposition in West Virginia and Maryland, American Electric Power, headquartered in Columbus, Ohio, and Allegheny Energy of Greenburg, Pa., last week said they are going to reroute their planned 765-KV, […]

By Kennedy Maize   What will the new president really do once on infrastructure spending, despite the anodyne economic platitudes of the campaign? My guess is we will see the greatest economic stimulus effort since WW2. Deficits be damned. That’s probably good. The economic enemy is deflation, not inflation, if the Great Depression is any […]

A report from the front lines of the alleged global warming war. The Anchorage Daily News reported on Monday, Oct. 13, 2008, that summer snow loss in the state in 2008 was less than winter snowfall, reversing a trend of two centuries. The newspaper said that “unusually large amounts of winter snow were followed by […]

Desperate to score points in a crucial state where they are in the double-digit dumps, the Republican McCain-Palin presidential ticket rolled out their heartfelt support for “clean coal technologies” at a rally in Scranton, Pa., this week. Vice Presidential Nominee Sarah Palin appeared in full throat. Her homage to coal, of course, came despite McCain’s […]

Faced with soaring energy prices, researchers and developers worldwide are giving compressed air energy storage (CAES)—a technology almost 50 years old—a dusting, a spit shine, and a new life. In particular, they see it as a critical component for the dispatch of wind and other renewable power. The technology, which involves storing off-peak-generated energy in […]

The U.S., which continues to lead the world in on-line geothermal energy capacity, saw a 20% jump in new power projects since January this year, a survey released by the Geothermal Energy Association (GEA) in August showed.

Top Plant: The staff of the Rawhide Energy Station have been racking up operating stats and an environmental performance record that is the envy of other plant managers. In the past decade Rawhide has enjoyed an equivalent availability factor in the mid- to high 90s and an average capacity factor approaching 90%. Still not content with this performance, Rawhide invested in new technology and equipment upgrades to further optimize performance, reduce emissions, and keep cost competitive.

In early August, a special transport departed from Voith Siemens Hydro’s Heidenheim workshop bearing the company’s 300-ton, 300-MVA hydro motor-generator back to Schluchseewerk AG’s Wehr pumped-storage station in Germany’s Black Forest.

Entergy christened its Performance Monitoring and Diagnostic Center several years ago to leverage the expertise of its most senior operators and technicians across the company’s entire fleet of plants. The center also makes use of advanced software tools that increase plant availability and reliability by identifying faults before they become major, unplanned outages. The center paid for itself for years to come with a single “big catch” last year.

Through asphalt, researchers are looking to develop a solar collector that could turn roads and parking lots into ubiquitous—and inexpensive—sources of electricity and hot water.

Top Plant: From tall skyscrapers and flashing neon signs to Buddhist temples and pagodas, South Korea is a mixture of the new and old Asia. Doing its part to help modernize this country, the Boryeong Thermal Power Complex operates six coal-fired 500-MW units that provide electricity to power South Korea’s economic growth. One of the important reasons for this facility’s overall success is its operational reliability. An example of this is Boryeong Unit 3’s outstanding achievement of 3,000 days of trouble-free operation.

A utility evaluated various methods of obtaining a NO_x reduction of at least 30%, as required by upcoming regulations for its boiler, which originally produced 0.54 lb of NO_x/million Btu at 410 MW full load. Nalco Mobotec engineers performed a computational fluid dynamics (CFD) simulation of the boiler to first understand the boiler’s combustion process and then determine the most economical method to achieve the required NO_x reduction.

Top Plant: Alliant Energy’s Dubuque Generating Station is a fine example of why small doesn’t mean insignificant in the power generation industry. This winner of the EUCG Best Performer award in the small plant category shows that its operating excellence towers over that of many larger and much newer coal-fired power plants.

As fluid passes through Exact Flow’s new DX-DL dual-rotor turbine flowmeter, the dual rotors become hydraulically coupled due to their counter-rotation. Not only does this allow the rotors to overcome the inertia and drag that typically affect single-rotor turbine flowmeters, it also extends the flow range to 500:1—five times the 100:1 flow range of a […]

The United States is used to transporting fuels to electric generation centers that are close to where the power supply is needed. We see trains carry coal by the carload from resource-rich areas to generation centers across the country. Natural gas is distributed through pipelines. Even uranium is transported to supply our nuclear stations. However, […]

Enclosure manufacturer Rittal Corp.’s latest products are designed to be incorporated into electrical systems to help ensure safety against arc flash hazards. Data interface flaps, shown here, provide rapid system access via integrated USB, SUB-D9 RJ 45, and NEMA 5-15 sockets when needed. The affected enclosure remains closed and is thereby protected from ambient influences […]

Republican presidential candidate John McCain made reference to the word “fight” 25 times during his September 4 nomination acceptance speech. While watching McCain’s histrionics, my mind wandered back to another historic fight—the “Rumble in the Jungle.” Muhammad Ali, arguably the best boxer who ever stepped into the squared circle, was pitted against then-World Champion George […]
