  • POWER Digest (January 2012)

    South Korea, China Poised to Make Colossal Investments in Wind Power. South Korea, a nation that recently announced it would spend 1 trillion won ($884 million) on feed-in tariffs for wind and solar projects, on Nov. 10 said it planned to invest 10.2 trillion won ($9 billion) in a 2.5-GW offshore wind farm that could […]

  • Handheld Vibration Meter

    Columbia Research Laboratories has introduced the Model VM-300 vibration meter, a general purpose vibration-measuring instrument designed for periodic routine checks of industrial equipment where portability and ease of use are required. Acceleration, velocity, and displacement measurement modes are provided, along with a number of value-enhancing features. Dual power allows the VM-300 to be powered from […]

  • Level Switches Keep Electrostatic Precipitators Online

    Measuring the level of dust and fly ash collected in electrostatic precipitators (ESPs) is a very difficult technical problem. At one utility, level switches were so unreliable that operators could not trust their readings because failures were so frequent. When a switch did fail, the precipitator would often clog up, costing the utility up to $100,000 in downtime and repair costs.

  • U.S.-China Solar Trade Dispute Gets Thornier

    A trade row between the Chinese government and solar panel makers around the world intensified in December. As China’s Ministry of Commerce refuted allegations that the Chinese government uses illegal subsidies, discounts for raw materials, preferential loans, tax incentives, and currency manipulation to drive down prices and amplify exports of Chinese solar photovoltaic (PV) panels, the U.S. International Trade Commission (ITC) affirmed the U.S. solar industry is “materially injured” by imports, at “less than fair value,” of Chinese crystalline silicon PV cells and modules.

  • Asian Sub-Bituminous Coal Users’ Group Formed

    Over the past 11 years, the Powder River Basin Coal Users’ Group (PRBCUG) has grown to become the voice of North American generating companies that are dedicated to the safe and efficient use of PRB coal. POWER, the group’s media sponsor, has reported on the PRBCUG’s annual meetings, which are colocated with the ELECTRIC POWER Conference & Exhibition each year. POWER also reports annually on the group’s coal plant of the year award. For 2011, in the large plant category the award went to Kansas City Power & Light’s Iatan Unit 2 (see our August 2011 issue); the small plant category winner, Muscatine Power & Water, is profiled in this issue, beginning on page 56.

  • Marmaduke Award Trophy Presented

    The 2011 Marmaduke Award winner was CTG Universidad, a two-unit combustion turbine plant built in the early 1970s in Monterrey, Mexico. The award was made to the plant in recognition of its upgrade of one 14-MW unit to operate as a synchronous condenser, thus relaxing power restrictions caused by a lack of sufficient reactive power production in the north of the city. More reactive power production by this urban plant also allows delivery of more power produced by efficient combined cycle plants located outside the city, because it reduces the amount of reactive power that must be moved over transmission lines.

  • Correction

    In “Siemens Releases ‘ShapingPower’ Option for Renewables Integration” (December 2011), the Figure 3 callouts for wind and solar were reversed. POWER regrets the error. A corrected version can be found in the online version of the article. â– 

  • Condenser Life Cycle Seminar

    The November issue of POWER featured a special section titled “Condenser Life Cycle.” That set of four articles covered topics including condenser performance, operation and maintenance (O&M), failure mechanisms, and retubing—topics you will surely find useful at some time in your career. The authors of those four articles work for companies that are part of […]

  • THE BIG PICTURE: Gas Taxes

    After years of political wrangling, coal-rich Australia in November passed legislation that will require the nation’s top 500 polluters, starting in July 2012, to pay a tax at a fixed price of A$23 (US$23.50) per ton of carbon. The tax increases 2.5% annually until 2015, when an emissions trading program will begin. With the Kyoto […]

  • My Top 10 Predictions for 2012

    The New Year will be pivotal for the power generation industry, as you will read in our 2012 Industry Forecast (p. 26) and my list of predictions below. Looking back over the past year, I again gave myself a B+ on my 2011 predictions (see p. 33 for a rundown of my individual scores).
