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 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.

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 rotating parts—often cascading impacts. An operator of many utility-scale steam turbines shares its extensive field experience identifying the root cause of failures as well as […]

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.

The ATC DigiTec Division of Marsh Bellofram Corp. launched its highly compact 758-GF86/XF86 series of industrial open-face AC tachometer generators, part of its WESTCON product family. The tachometers are designed primarily for use on shaft ends to measure speeds of up to 100,000 rpm and extremely low torque burdens of less than 1 ounce-inch. Designed […]

LUDECA released a new version of its “Laser Align” mobile application. The application provides a free reference tool for shaft alignment of rotating equipment. It allows users to access important reference material and learn about key laser shaft alignment concepts, and it now has an interactive “Tolerance Table.” When users input their machine’s revolution per […]

Pentair Valves & Controls’ newly introduced Crosby HCI ISOFLEX is a high-capacity safety valve to help power plant operators reduce lifecycle costs and minimize shutdown periods. The valve ensures cost-effective power plant operation with a unique full-nozzle, flanged design and adjustable lift option that reduces maintenance costs while maximizing plant efficiency. Specifically designed for 300 […]

A rule proposed by the Environmental Protection Agency (EPA) directs 36 states to revise their Clean Air Act State Implementation Plans (SIPs) to eliminate exemptions for excess emissions of air pollutants at power plants during startup, shutdown, or when the plant malfunctions.

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.

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.

The new Garlock 204 EPS (extreme pressure service) abrupt arched expansion joint is now available for applications where necessary rated pressures exceed those of the Garlock Style 204 and 204 HP designs. Fully customizable and available in concentric or eccentric designs, the expansion joint features a seamless tube to ensure a reliable seal from flange […]

Much of the natural gas industry was holding its breath when the Matt Damon film Promised Land came out in January, but a few groups weren’t waiting for the fallout.

Power plant emissions of sulfur dioxide (SO₂) and nitrogen oxides (NO_x) in the U.S. declined to their lowest level since 1990, the Energy Information Administration (EIA) said in early March.

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.

Larson Electronics announced the release of a boiler inspection light with folding boom designed to provide versatile deployment capabilities and high-output illumination. The WALBL-2X1000WMH Boiler Light features a right-angle extension arm, wheeled base, and a pair of 1,000-W metal halide lamps for effective illumination during the servicing and maintenance of boilers and tanks. The boiler […]

The next big shale boom may be taking shape out West. But the challenges of developing the Monterey shale may not be what you think.

The Environmental Protection Agency (EPA) estimates final regulations curbing greenhouse gas (GHG), mercury, and air toxics emissions from new sources could appear in the Federal Register by the end of April. Also forthcoming are final cooling water intake rules and proposed effluent guidelines. The coal ash rule, which has no target date for a final rule, may not be issued this year, the agency said.

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.

The ABB Low Voltage Products division released a line of OVR PV UL 1449 3rd Edition, pluggable DC DIN Rail surge protection devices (SPD) specifically designed for photovoltaic (PV) applications. The new SPDs protect solar panels from damage from direct and indirect lightning strikes, which solar panels are especially susceptible to because of their large, […]

The power and gas industries may be joined at the hip, but judging from the talk at a recent conference, not everyone is excited about future directions.

Germany’s race away from nuclear and coal to a system heavy with renewables has not followed the expected course. Nuclear and coal plants were supposed to close. Instead, gas plants are closing and coal is making a comeback.

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.

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.

With the increasing interdependency of the natural gas and electricity, the number of economic and regulatory factors than can shift the future direction of both industries is growing substantially.

New York Mayor Michael Bloomberg recently gave a presentation in Washington, where he stated: “Coal is dead.” Fortunately, both for the prosperity of the United States and the goal to alleviate poverty for billions of people across the world, Bloomberg’s projection is much different from what is actually happening.

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.

California’s push to boost its renewable capacity may be doing more than spurring the development of wind and solar. A review of recent data suggests the state’s regulatory schemes have the potential to spell the end of fossil-fuel generation altogether.

Wind industry’s “inflated numbers” and “erroneous conclusions” misled Washington lawmakers to extend the production tax credit.

In February, the California Public Utilities Commission (CPUC) yet again missed an important opportunity to correct structural flaws that have plagued the state’s wholesale generation market in the wake of the 2001 energy crisis.

You may think of carbon capture and sequestration as a coal industry issue, but two forward-thinking companies are joining forces to make it work for gas.
