  • Smart Grid 2011: More than Meters

    The concept of a smart grid may have been born in the U.S.A., but it’s hitting an adolescent growth spurt just about everywhere else first. Meanwhile, in the U.S., both the regulators and companies that see great potential in a smarter grid are realizing that making substantial smart grid progress will first require making both people and policies smarter. There’s one exception, one piece of the smart grid, that could face fewer obstacles to adoption, and that’s because it offers more obvious and visible benefits to its users: electric vehicles (EVs).

  • German Researchers Develop Cost-Efficient Small Hydro Plant

    Researchers at Germany’s Technische Universitaet Muenchen (TUM) claim to have developed a small-scale hydroelectric power plant that is capable of operating profitably even at modest dam heights while minimizing impact on waterways.

  • My Top 10 Predictions for 2011

    It’s time to pull my crystal ball out of storage, polish it up, and give you another round of U.S. industry predictions for 2011. I graded last year’s predictions B+ (for a complete rundown of how I graded each prediction, see page 32), but I’m convinced I’ll do better in 2011.

  • IEA: Global Power Demand to Surge 2.2% Annually Through 2035

    Though electricity generation has entered a key period of transition—as investment shifts to low-carbon technologies—world electricity demand is set to grow faster than any other “final form of energy,” the International Energy Agency (IEA) says in its latest annual World Energy Outlook.

  • Construction of Tibetan Dam Sets Off Cross-Border Tensions

    China in mid-November embarked upon building the first massive hydropower project in Tibet, a 6 x 85-MW plant straddling the middle reaches of the mighty Yarlung Tsangpo River (Figure 2). According to the Hunan Daily, a Chinese state-owned enterprise, Sinohydro began damming the river in Shannan Prefecture, Tibet, on Nov. 8, kicking off the 7.9 billion yuan ($1.2 billion) “run of the river” project that is estimated to generate electricity for the surrounding region by 2014.

  • MHI Prepares to Test J-Series in Japan

    Mitsubishi Heavy Industries (MHI) has begun converting a combined-cycle plant in Japan to prepare for verification testing of its long-anticipated J-Series gas turbine in February 2011—a system that the company claims has the most power generation capacity and highest thermal efficiency in the 1,600C turbine inlet temperature class (Figure 3). The work being carried out at the Takasago Machinery Works facility in Hyogo Prefecture (where the company’s G-Series gas turbines were tested) includes installation of the J-Series turbine, and it marks another major milestone in the technology’s development.

  • TransCanada Opens 683-MW Halton Hills Combined-Cycle Plant

    TransCanada Corp. on Oct. 28 officially opened its C$700 million Halton Hills Generating Station. The 683-MW 2 x 1 combined-cycle plant on a greenfield site in Ontario (Figure 5) will operate under a 20-year power purchase agreement with the Ontario Power Authority (OPA). Construction of the peaker plant started in December 2007 and was completed on time and on budget, TransCanada said.

  • Exelon Enjoys Benefits of Online Transformer Monitoring

    In all of these cases, frequent oil analysis monitoring and preestablished action plans were able to allow for transformer replacement before the occurrence of a catastrophic failure. Exelon’s experience, as well as that of other power utilities across the grid, has spawned a report by the Institute of Nuclear Power Operations (INPO) of Atlanta, Georgia, that recommends that performance monitoring and trending be applied to all large transformers in order to establish a baseline for transformer maintenance strategies.

  • Selecting a Specialty Accumulator

    Sudden bumps and shocks are great fun when you are off-roading or are riding on a rollercoaster. But when you are operating a piece of equipment, you want it to be running as smoothly as a Cadillac rolling down the interstate. Sudden changes in pressure produce vibration, cavitation, and water hammer and generally lower the lifespan and reliability of fluid systems.
