  • U.S. Smart Grid Forecast: Flurries of Activity

    A number of factors are coalescing to create the most hospitable climate for smart grid development activities that has yet been seen in the U.S. Here’s a look at those elements and at the different models and motivations for smart grid project development across the country.

  • The Impact of Carbon Trading on Performance: What Europe’s Experience Can Teach North American Generators

    The European carbon trading system experience suggests that North American generators should expect severely altered coal-fired power plant operating profiles if cap-and-trade legislation becomes law. In a groundbreaking study, Solomon Associates predicts the reduction in mean run time that North American generators should expect. The trends outlined in this study provide an overview of some of the broad challenges facing generators in moving to a carbon-constrained market environment.

  • Advanced Refractory Lining Improves Gasifier Reliability

    Successful testing of a new refractory lining material developed by the Office of Fossil Energy’s National Energy Technology Laboratory (NETL) could lead to higher reliability and improved economics of gasification technology.

  • Interconnection Animus: Do Regulatory Procedures Create a “Tragedy of the Commons”?

    What’s the real “tragedy of the commons?” It is legal, regulatory, cultural, or political? And is there is way out?

  • What Do Customers Expect from the Smart Grid?

    Xcel Energy’s SmartGridCity enterprise in Boulder, Colo., is one of the most talked-about smart grid projects. Here’s what some Boulder utility customers are saying about it.

  • A New Foundation for Future Growth

    As the economy begins to grow again, the banking industry continues to stabilize, and lawmakers work on finalizing climate change legislation, the decisions made in 2010 will lay the foundation for the power industry for decades to come.

  • High-Temperature Gas-Cooled Reactor Concept Moves Forward

    Researchers from the Idaho National Laboratory (INL) say they have developed a new type of nuclear fuel for use in next-generation high-temperature gas reactors that produces less waste — a major step forward for the Next Generation Nuclear Plant (NGNP).

  • For Utilities, Derivatives Is Not a Dirty Word

    Financial derivatives make sense for the electricity business, providing protection against price swings, and don’t require additional regulation.

  • Which Country’s Grid Is the Smartest?

    The U.S. isn’t the only country evaluating and implementing elements of smart grid technology. In fact, it could be argued that other nations are much farther along the path to a comprehensive, technically advanced system for integrating renewables, managing load, and creating a more flexible power grid.

  • Dollars and Dirt: Investing in Infrastructure

    The familiar saying "as goes California, so goes the nation" seems to apply to the many states that have been unable to invest in infrastructure improvements because they are crushed by debt and shrinking revenues. Will California and energy project developers continue to invest in energy infrastructure in 2010 given the limited availability of private capital, shaky state finances, and shifting regulatory climate?

  • Predicting Hurricane-Related Outages

    Researchers from John Hopkins and Texas A&M universities say that they have found a way to accurately predict power outages in advance of a hurricane. Computer models developed using data from Hurricane Katrina and four other destructive storms could save utilities substantial amounts of money and help facilitate rapid restoration of power after a storm, they say.

  • For a Secure Energy Future, Obama Must Be Like Ike

    President Dwight David Eisenhower built the interstate highway system more than 50 years ago. Is it time for the U.S., when it comes to the electric power grid, to be like Ike?

  • The Smart Grid Has a Growth Spurt

    Which country has the smartest grid? Which U.S. state has the most smart meters? What’s Google got to do with the grid? Answers to these questions and more can be found in our web exclusives. Here’s a taste of what you’ll find online.

  • Sealing Transformer Oil and SF6 Leaks Quickly and Effectively

    Transformers, which are prone to leaking, are an excellent example of where using the right materials and techniques can quickly reduce cleanup costs and potential environmental damage from a fluid leak. Transformer leaks are most commonly caused by degrading cork gaskets or holes in the radiator fins or the steel tank. Often these leaks are slow drips, but occasionally a catastrophic leak will occur, spilling hundreds of gallons of mineral oil into the environment and causing the transformer to short-circuit, causing further health and safety concerns. These dangers, coupled with transformers’ isolated locations, make inspection, repair, and maintenance a major challenge.

  • Brazil: Latin America’s Beacon

    With the eighth-largest economy in the world, Brazil has a clear need for power, but balancing supply and demand has proven tricky in recent decades. Even in a country where over 80% of generation capacity comes from renewables, planning for future capacity additions isn’t straightforward or easy.

  • When to Use an Oil Skimmer

    Oil skimmers are very effective in removing oil from wastewater before discharge but are also perhaps the most efficient and economical approach.

  • Tuning Ammonia Flow to Optimize SCR Performance

    The selective catalytic reduction system has become ubiquitous throughout the world of power plants. Emission control requirements are ever-more stringent, and the cost of excursions is becoming increasingly high. The key to staying under the regulators’ radar is precisely controlling the ammonia injected into the boiler. A new control strategy does precisely that.

  • Thin, Flange-Style Magnetic Encoders

    Baumer introduced the new MOR 90 and MOR 105 magnetic incremental encoders for improved speed and position control on electric motors, drives, gearboxes, and conveyors. Measuring just 14 mm thick, these extremely thin, flange-style encoders are virtually imperceptible when positioned between the motor and the gearbox and have little effect on the overall size of […]

  • Low-Noise Remote Charge Converter

    Endevco Corp. launched Model 2771C-XX, an ultra-low-noise remote charge converter (RCC) designed for use with charge output piezoelectric sensors within applications such as nuclear power plant/regenerative energy and environmental testing. The model offers a rugged two-wire (IEPE), single-ended design that operates from constant current power (4-20 mA). Both RCC signal output and current to the […]

  • Miniature Stainless Steel Pressure Switch

    Ashcroft A-Series pressure switches are designed for tough OEM and industrial applications that require a durable, high-quality miniature switch.

Small dimensions, a choice of connections, […]

  • Carbon-Cutting Solution: Dynamic Demand Technology

    Once upon a time, climate change felt like a distant threat on the horizon. Now it is happening in front of our very eyes. Across the world, global warming is sparking more intense heat waves, more flooding, and more droughts. If climate change continues at its current pace, the social, environmental, and economic costs don’t […]

  • The Resurrection of Underground Coal Gasification

    News this past November that Australian company Cougar Energy had begun developing a pilot project to generate power from coal still underground has reignited interest in the 100-year-old alternative energy technology. The company’s planned A$8 million program — expected to be started in the first quarter of 2010 — will be conducted 10 kilometers south of Kingaroy, in southern Queensland. If it is successful, it could lead to the establishment of a 400-MW baseload power station, Cougar Energy officials say.

  • Replacing an HP/IP Rotor

    Today’s power plant owners face many challenges, including the aging and degradation of equipment. Steam turbines at times may be condemned due to operating inefficiency or rising vibration levels. In such cases the options may be few because the turbine may require a full or partial rotor section replacement. The good news is that a rotor section replacement can be performed in a relatively short time, depending upon the original rotor configuration. Here’s one example.
