TVA’s Paradise Unit 2 Sets New Continuous Operations Record

Paradise Fossil Plant Unit 2’s record-setting performance of 259+ days of continuous operation for a cyclone-fired boiler is attributed to excellence in plant operations and maintenance processes, a diligent and well-trained staff, and leadership that places high value on both. The Paradise experience proves that plants can’t help getting older, but they don’t have to get old.

Electrostatic Precipitator Upgrade Opportunities

The results of stack emissions testing conducted at several coal-fired power plants during the past three years have provided useful guidance for plant operators who are required to meet new federal guidelines regarding the release of particulate matter. The data and guidelines presented here will assist those who operate plants with electrostatic precipitators to develop a strategy for filterable particulate emissions control.


Enhancing Mercury Capture: An Asset-Based Approach

The Mercury and Air Toxics Standards will soon force many coal-fired plants to install mercury-specific emission control equipment. Planners can use particular characteristics of a plant to quickly screen for the best mercury removal technology.


Nuclear Waste Disposal Sites Still Rare After All These Years

Nuclear power generation is well established, but efforts worldwide to develop permanent disposal sites for highly radioactive waste remain nascent at best. If this were a horse race, you’d have to say the smaller horses are winning.


Preparing for a NERC CIP Audit

Undergoing a NERC CIP audit is an ordeal, particularly when the ground rules are not clearly spelled out in advance. An experienced NERC CIP auditor lays out a comprehensive five-step plan that will show you how to prepare for a successful audit.


Steam Turbine Rotor Vibration Failures: Causes and Solutions

Steam turbine rotors bend during operation, but the bearing and supports are designed to keep the static and dynamic forces under control. However, bending can cause impact between stationary and…

Too Dumb to Meter, Part 10

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the 18th and 19th chapters, “The Great Uranium Conspiracy” and “Breeding at the Turkey Farm,” the final two chapters of the “False Scarcity and Fools for Fuels” section.

Wind Power Incidents in China: Investigation and Solutions

China’s installed wind power capacity has doubled for six consecutive years. However, along with the increased capacity come wind power accidents, incidents, and failures. Considering the sharply rising amount of wind power, the authors examine and sort wind technology failures by type and explore their causes in an effort to offer solutions.

The Pacific Northwest’s Wind Fleet Integration Struggles

Mae West said, “Too much of a good thing can be taxing.” The Pacific Northwest has a good thing—plentiful, carbon-free power from its huge wind and hydroelectric fleets. But wind’s huge variability can be taxing. The Northwest’s scramble to integrate growing wind generation, and the resulting litigation melee, underscore the importance of quickly solving the variable resource integration puzzle.

Battling White Rust

Does your power plant use a chiller for combustion turbine inlet air cooling or other processes that reject heat? If so, there is a good chance you also have an auxiliary cooling tower or a wet surface air cooler to cool these systems.

Bulgarian PM Quits Over Power Price Protests

Protests in more than 20 cities by tens of thousands of Bulgarians over January electricity bills that averaged more than €100 ($130) forced the country’s prime minister, Boyko Borissov, and his center-right government to resign in mid-February.

Europe Embraces Shale Gas

Several European governments have so far this year bucked a reluctance to extract shale gas via hydraulic fracking even as the practice continues to be strongly opposed in countries like France and Bulgaria.

THE BIG PICTURE: Subsidy Tug-of-War

Government decisions to subsidize renewable power to increase its capacity for environmental and security reasons have spurred investments but also increased cross-border tensions. Increasingly, legal actions that seek to settle international trade disputes allege unfair subsidization.

America’s Growth Corridors

The familiar Red State–Blue State map is a symbolic means of quickly communicating political preferences. The maps aren’t meant to be predictive of job, economic, or population trends, yet a recent think tank’s report suggests the metaphor may have broader significance.
