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.

Paul Browning, vice president, thermal products for GE Power & Water, sees the greatest short-term business opportunities beyond the U.S., in “high-speed” countries.

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.

Utilities have achieved success by supplying electricity from central station plants (the supply side) to a grid that carries electricity to customers (the demand side). One way to improve the efficiency of this supply chain is by adopting smart grid technology. The weak link in that chain is convincing customers to use, and regulators to invest in, the smart grid.

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.

Bill Newsom—vice president, sales & marketing, Mitsubishi Power Systems Americas Inc.—talks about taking the long view with the company’s U.S. investments.

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).

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.

TANE and Shaw to Provide EPC Services for South Texas Expansion. Nuclear Innovation North America LLC (NINA), the nuclear development company jointly owned by NRG Energy and Toshiba Corp., on Nov. 29 announced that it awarded the engineering, procurement, and construction (EPC) contract for South Texas Projects Units 3 and 4 to a restructured EPC […]

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.
