During my 30-year career at the American Public Power Association (APPA), I’ve had a front-row seat for most of the major events in our industry’s recent history. So it disturbs me when my view of our history is 180 degrees out of phase with how others perceive it. Such was the case with the preamble […]

The eyes of Texas—and the rest of the world—are upon NRG Energy after its September application for licenses for two new reactors at South Texas Project (see Global Monitor). The filing was the first of its kind in nearly three decades and the first of up to 30 like it expected over the next few […]

This May, the Arizona Corporation Commission (ACC) rejected a proposal by Southern California Edison (SCE) to build Devers-Palo Verde No. 2 (DPV2)—a 230-mile-long, high-voltage transmission line connecting California and Arizona. The line, approved by the California Public Utilities Commission (CPUC) four months earlier, would enable SCE to import additional low-cost electricity from Arizona. The ACC’s rejection of DPV2 highlights a significant challenge for state and regional resource planners—weighing state interests against the regional benefits of interstate electricity commerce.

TVA’s 1,155-MW Browns Ferry Unit 1 returned to service on May 22 after sitting idle since 1985, when all three units were shut down to address management and operational concerns. Units 2 and 3 returned to service in 1991 and 1995, respectively, after extensive upgrades to controls, electrical systems, pumps, motors, and more. The return of Unit 1 began in 2002 with a five-year $1.8 billion restart plan to make all three units essentially identical, and that goal was accomplished in style. Welcome back, Unit 1.

While noting marginal improvements since last year, America’s power reliability watchdog recently warned that the nation’s growing thirst for electricity will still far exceed planned increases in generation capacity over the next 10 years, and that reserve margins could dip below optimal levels within two or three years in California, the Rocky Mountain states, New […]

Burning biomass or nonrecyclable commercial, municipal, or industrial waste along with coal represents one of the nearest-term and lowest-cost options for reducing carbon dioxide (CO 2) emissions from existing utility power plants. At more than 150 plants worldwide, doing so has produced lower CO 2 emissions than burning coal alone. Indeed, with the number of […]

On November 20, New York City Mayor Michael R. Bloomberg and top executives of the real estate company Tishman Speyer announced several energy conservation measures to be implemented at Rockefeller Center this holiday season. One is the outfitting of its famous Norway Spruce Christmas tree with 30,000 light-emitting diodes (LEDs) strung on five miles of […]

Like many older coal-fired plants, Westar Energy’s Jeffrey Energy Center (JEC) was built with traditional, pneumatic flyash-handling and removal systems. Such systems collect flyash in hoppers attached to the bottom of a unit’s electrostatic precipitator (ESP) and/or baghouse. Periodically, the hoppers are emptied into tanks and the flyash is conveyed away for disposal or beneficiation. […]
