U.S. Supreme Court rulings in two recent cases further advance the rights of employees in disputes with employers, continuing a long-term trend in federal law on employment discrimination.

Hamworthy Peabody Combustion’s new Q-jet Low NOx Burner Optimization Kit can be retrofitted to practically any existing burner, regardless of manufacturer, to increase efficiency and reduce maintenance. In addition, the Q-jet Kit eliminates the need to replace complete burner assemblies just to meet emissions requirements, saving time and money. A key feature is that the […]

The devastation in Japan has focused new attention on supply chain issues and the impact of the partial collapse of that country’s manufacturing infrastructure on both Japanese imports and exports.

Valve-maker Conval announced that its popular Camseal zero-leakage ball valves now have forged bodies. These new forged ball valves are available in half-inch through 4-inch sizes with top entry, socket weld, butt weld, and flanged ends. Pressure classes range from ASME 900 through 4500. Camseal forged ball valves feature zero body leakage, zero seat leakage, zero seal […]

John Hanger, who led Pennsylvania’s Department of Environmental Protection until January, talked with ProPublica earlier this year about the challenges of trying to regulate the expanding drilling industry.

A renewed attack on nuclear power immediately followed the March 11 catastrophe at the six-unit Fukushima Daiichi nuclear power complex in Japan. At least one legislator and a multitude of anti-nuclear groups have demanded that the U.S. cease approval of all new nuclear plants for the foreseeable future and/or close our Mark I boiling water reactor (BWR) plants. This knee-jerk response adds nothing substantive to the nuclear safety debate. (Be sure to read our cover story for more on this issue.)

The electric power generation landscape in both America and the rest of the world is poised to undergo a fundamental transformation in the next several decades. Global energy consumption is projected to rise dramatically by 2035, and the methods by which we generate electricity and the fuels we choose to use will begin to change as well.

Not complying with current law can be expensive in today’s legal climate. Employers should review their employee handbooks and employment-related policies to make sure they are up to date. More importantly, employers should draft their handbooks so that employees actually read them and follow their policies.

Weeks after a massive magnitude 9.0 earthquake and subsequent 14-meter-high tsunami devastated Fukushima Prefecture in northeastern Japan, workers from the Tokyo Electric Power Co. (TEPCO) were still struggling to regain control of four severely damaged reactors at the six-unit Fukushima Daiichi nuclear power plant.

The People’s Republic of China’s Congress approved a much-anticipated draft of the country’s 12th Five-Year Plan (2011–2015) on March 14. Along with key objectives that included boosting its gross domestic product (GDP) by 7% annually on average, the country for the first time in a five-year plan established targets to tackle climate change. It plans to reduce carbon dioxide emissions per unit of GDP by 17% from 2010 levels by 2015 and to reduce energy consumption per unit of GDP by 16% from 2010 levels by 2015.

Many large utility-scale units with copper alloy condensers and feedwater heaters lose generating capacity when copper and copper oxide deposits develop on high-pressure (HP) steam turbine blading. It is not unusual for a 400-MW unit to lose 10% of its generating capacity over a six-month period when water treatment processes aren’t properly tuned to prevent copper transport in the steam and condensate systems. In fact, one utility reported that it lost 20 MW of capacity in one month because of such deposits. The financial implications of such deposits, particularly in power markets where plants are pushed to their generating limits, are tremendous.

Regulators are asked to balance a societal need with the cost burden placed on those who pay for the service. Sometimes they forget that it’s other people’s money at stake.

Subsidized by the Dutch government, a number of Dutch utilities, the European Membrane Institute at the University of Twente, and Dutch consulting firm KEMA have, for over a decade, been testing membrane technology that promises to directly convert water vapor from power and other industrial plants’ flue gases into drinking water. The technology could provide a new source of large volumes of potable water.

This series of articles focuses on the nuts and bolts of predictive maintenance (PdM), also known as condition-based maintenance. A well-defined and well-executed PdM program saves time and money by reducing unneeded time-based maintenance tasks and by identifying and fixing problems before they cause equipment failure or plant shutdown. In this article, we begin introducing condition-monitoring techniques commonly in use at power plants.

It’s not just hard finding good help these days. It’s hard finding honest help, too.

Competition among offshore wind turbine vendors vying for market share went into overdrive in the first three months of 2011 as several key players announced gigantic new turbine models.

The U.S. Court of Appeals for the Ninth Circuit recently dealt another setback to the use of Section 216 of the Federal Power Act, which gives the Federal Energy Regulatory Commission (FERC) “backstop” authority to site electric transmission lines. Although enacted in 2005, this authority has never been used by FERC, and it can be questioned whether it ever will be used.

A major technical advance in hydroelectric dam safety was achieved this March as Alstom’s Chinese arm, the Tianjin Alstom Hydro Co. (TAH), delivered what it called “the world’s first self-closing electronic ring gate control system” to the Ahai hydropower project in China.

If coal is to be a viable long-term fuel for a significant percentage of electricity generation, research and development is needed to increase thermal efficiency, demonstrate cost-effective and secure carbon dioxide capture and storage, further improve emission controls, and reduce water demands.

The Canadian province of Saskatchewan on Tuesday approved construction of a C$1.24 billion project that will integrate and demonstrate carbon capture and storage (CCS) at an aging Boundary Dam Power Station unit near Estevan.

The nuclear crisis at Fukushima Daiichi could increase costs for existing and future nuclear power plants, increase scrutiny on relicensing procedures, and cause a reevaluation of the entire spent fuel management system, researchers from the Massachusetts Institute of Technology (MIT) said as they released a comprehensive report on the future of the nuclear fuel cycle.

Last week, lawmakers from Indiana approved a bill that could allow utilities to charge consumers costs incurred to extend the lives of nuclear reactors, and on Tuesday, Iowa legislators voted to begin the process of developing a new nuclear plant.

As much as 55% of Unit 1’s reactor core at the quake-stricken Fukushima Daiichi nuclear power plant is thought to be damaged; Unit 2’s core is estimated to be 35% damaged, as is 30% of Unit 3’s core, the Tokyo Electric Power Co. (TEPCO) said today. Seven weeks after the crisis began, the utility—which has also admitted damage of the spent fuel rods at Unit 4—continues all efforts to cool the affected reactors.

A Georgia administrative law judge has remanded an air permit for LS Power’s proposed 1,200-MW Longleaf coal-fired power plant to the state Environmental Protection Division (EPD). The judge found that the permit did not sufficiently limit pollution and ordered the regulatory body to amend the permit to include federally approved tests for five air pollutants.

Entergy Corp.’s Vermont Yankee nuclear power plant hit another hurdle on Tuesday as the Vermont Electric Cooperative (VEC) rejected a 20-year power purchase contract at below market prices.

An annual report released on Tuesday by the U.S. Energy Information Administration (EIA) that assesses energy and technology market trends forecasts that if current laws and regulations remain unchanged, natural gas and renewables will see strong growth in the electricity sector. The report also suggests that expected regulations from the Environmental Protection Agency (EPA) will have an impact on the U.S. power sector, most notably on its fleet of coal-fired power plants.

NRG Energy, the majority owner and operator of the South Texas Project, on Tuesday said it was pulling its financial support for a multibillion-dollar project to build two new advanced boiler water reactors (ABWRs) at its nuclear plant in Matagorda County, Texas, because the  Japanese nuclear crisis had “diminished prospects” for that project.

The Tennessee Valley Authority (TVA) on Thursday said it would retire 18 older coal-fired units at three power plants starting next year as part of plans to idle or retire 2,700 MW of its 17,000 MW of coal-fired capacity by the end of 2017. The federally owned utility plans to replace the capacity with nuclear—proceeding with plans for Watts Bar Unit 2 and Bellefonte—as well as renewables, natural gas, and energy efficiency.

The Tokyo Electric Power Co. (TEPCO) unveiled a two-stage plan to put units at its quake and tsunami–crippled Fukushima Daiichi nuclear plant into cold shutdown within six to nine months, and the International Atomic Energy Agency (IAEA) said that if efforts go as planned, the amount of radiation may not increase.
