  • Ocean Power Prototypes Coast Ahead in the UK

    Marine energy prototypes in the UK are sailing ahead of entries from the rest of the world, propelled by government backing and public support.

  • Power Politics: Enron Lives!

    As director of public policy analysis in my last seven years at Enron, I participated in many legislative and regulatory debates involving electricity, although the public policy thrust of the company was the opposite of what I believed. While I favored free markets, the business model of Ken Lay (a PhD economist with years of Washington regulatory experience) centered on special government favor. Enron, for example, had seven profit centers geared to government pricing/rationing of carbon dioxide (CO2) emissions. And in the 1990s, the company was squarely behind a Btu tax. Today, Enron would be pushing cap and trade.

  • Despite Economic Downturn, Renewable Energy Development Expected to Move Forward

    While the overall economy is down, the effort to add renewable energy resources in the U.S. continues to push project development forward.

  • New-Generation Gas Turbines Steam Ahead

    This September, as Siemens Energy wrapped up testing of its H-class SGT5-8000H gas turbine at E.ON’s Irsching 4 gas power plant in Bavaria, Germany, the company raved about what it is calling "the world’s most powerful gas turbine."

  • What Is BACT for CO2?

    Assume, for the moment, that the U.S. Congress is unable to agree on legislation aimed at reducing carbon emissions from industry, vehicles, and power plants (the carrot approach). Further, assume that the Environmental Protection Agency (EPA) eventually promulgates rules that require power plants to reduce carbon emissions (the stick approach). Have you given any thought to the range of possible best available control technologies (BACT) that the EPA might require under the Clean Air Act (CAA)?

    News items of interest to power industry professionals.

  • NRC Concerns About AP1000 Structural Strength Could Delay Projects

    Concerns raised by the U.S. Nuclear Regulatory Commission (NRC) about the structural strength of Westinghouse Electric Co.’s AP1000 reactor could cause delays for several nuclear plants that planned to use the design in the U.S. — and it raises questions for new builds started or proposed in China and the UK.

  • Halar-Lined Chimney Remains Maintenance-Free

    A fiberglass-reinforced plastic (FRP) Halar stack liner was installed at Vattenfall’s 300-MW Unit 2 at the Nordjylland Power Station in 1995. The 112-meter-high (367-ft) stack, protected from corrosion by the ECTFE liner, is still in excellent condition and has not required any repairs during more than 13 years of service. (ECTFE is short for ethylene chlorotrifluoroethlyene polymer, marketed under the brand name Halar ECTFE [Halar] by Solvay Solexis.)

  • Rebuilding Feedwater Heaters While a Plant Is Online

    Rebuilding aged feedwater heaters can make better economic sense than buying new ones, because rebuilding reduces capital cost and plant outage expenses. At one Texas generating station, rebuilding saved one-third the cost of a new feedwater heater while improving the plant’s heat rate.

  • Automated Tube Bundle Water Jet System

    The ATL-5000 — a new, fully automated water jet system from NLB Corp. — cleans tube bundles three times faster than manual methods and features an adjustable lance stroke that allows the system to be configured for bundles of various lengths, up to 30 feet. The diesel-powered system has five rigid lances, each with a […]
