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.

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 […]

SunPower has introduced the SunPower C7 Tracker, a solar photovoltaic (PV) tracking system that concentrates the sun’s power seven times to achieve what the company claims could be “the lowest levelized cost of electricity (LCOE) for utility-scale solar power plants available today.” The C7 Tracker combines single-axis tracking technology with rows of parabolic mirrors, reflecting […]

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.

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 […]

Friends, colleagues, and co-workers uniformly called him "The Boss." His life was a story of failure after failure. His greatest fame was his greatest failure—a journey begun nearly 100 years ago, in 1914, to cross the desolate Antarctic continent by land. His doughty ship Endurance became trapped by the encroaching ice in the Weddell Sea north of the continent, isolating Sir Ernest Shackleton and his 27-man crew.

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.

There is a fine line between personnel management and intruding into the personal lives of employees. Staying on the right side of that line is challenging, particularly when prior legal decision are mixed.

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.

As the resource gets increased and more sophisticated scrutiny, natural gas from shale looks increasingly like a revolutionary force in energy markets. Most recently, the Washington-based environmental and energy think tank Resources for the Future rolled out a serious analysis of the new method of developing gas, and the issues it presents. The preliminary results look very positive for gas.

Reaching a major milestone, the Nuclear Regulatory Commission (NRC) on Thursday granted a final Design Certification Amendment to Westinghouse’s AP1000 pressurized water reactor design, paving the way for utilities in the U.S. to build nuclear plants using the third-generation reactor design.

The Environmental Protection Agency’s (EPA’s) issuance of its final Mercury and Air Toxics Standards (MATS)—a rule that will mandate all coal- and oil-fired power generating units limit emissions of heavy metals and acid gases using “maximum achievable control technology” (MACT)—last week provoked a range of reactions, including renewed concerns about its costs and impact on grid reliability.

In a key settlement that will resolve all environmentally based legal challenges against its 600-MW ultrasupercritical John W. Turk Jr. power plant under construction near Texarkana, Ark., Southwestern Electric Power Co. (SWEPCO) on Thursday agreed to several conditions, including phasing out a 528-MW coal-fired unit in Texas, building 400 MW of renewable power, and limiting new transmission lines in natural areas.

Exelon Corp. and Constellation Energy Group must sell three electricity generating plants in Maryland before the companies can proceed with their proposed $7.9 billion merger to level competition for wholesale electricity in the mid-Atlantic region, the U.S. Department of Justice (DOJ) said last week.

A report released on Thursday by the Department of Energy (DOE) examining the role that rare earth metals play in the manufacture of wind turbines, electric vehicles, and photovoltaic (PV) thin-film solar cells finds that these clean energy technologies may see supply disruptions for five rare earth metals (dysprosium, neodymium, terbium, europium, and yttrium) in the short term, though risks will generally decrease in the medium and long term.

By Kennedy Maize Washington, D.C., December 21, 2011 – Call it “The Little Breeder that Could.” Sixty years ago – December 21, 1951 – on the remote, high Idaho desert near Arco, legendary atomic scientist Walter Zinn from the Atomic Energy Commission’s Argonne lab outside Chicago, overseeing the Idaho project, wrote in his log book, […]

The Environmental Protection Agency (EPA) last week issued a final rule amending its Cross-State Air Pollution Rule (CSAPR) to include five more states in the ozone season nitrogen oxide (NOx) program. The final rule adds Oklahoma to the CSAPR program (for its ozone-season NOx emissions only), bringing the total number of states covered by the rule to 28.

Nine months after the Daiichi nuclear power plant in Japan’s Fukushima Prefecture was rocked by a magnitude 9.0 quake and an ensuing massive tsunami that plunged it into the worst nuclear crisis since Chernobyl, 25 years earlier, Japan’s prime minister, Yoshihiko Noda, on Friday said in a televised address that the plant’s four afflicted units have been brought to a state of cold shutdown. However, the crisis is far from over, he said.

A report was released last week by the European Commission that outlines possible ways European Union (EU) members can ensure energy security and competitiveness while meeting an ambitious goal of reducing their greenhouse gas (GHG) emissions from 80% to 95% below 1990 levels by 2050.

Duke-American Transmission Co. (DATC) will take charge of the design and development of a proposed 950-mile 500-kV transmission line that would deliver wind energy generated in eastern Wyoming to California and the southwestern U.S.

The Federal Energy Regulatory Commission (FERC) stunned officials of Duke Energy and Progress Energy on Thursday when it refused to unconditionally approve a $13.7 billion merger deal of the two companies that would have created the largest U.S. electric utility. The regulatory body cited concerns about the merger’s impact on power markets in North and South Carolina—where both companies are based—for its decision.

The Environmental Protection Agency (EPA) today issued its final Mercury and Air Toxics Standards (MATS), which will require about 40% of all coal-fired power plants in the U.S. to deploy pollution control technologies to curb emissions of mercury and other air pollutants such as arsenic and cyanide within three years. The regulation has been called the “most expensive order” aimed at companies that has been considered by the Obama administration.

By Kennedy Maize Washington, D.C., December 15, 2011 – The Federal Energy Regulatory Commission yesterday gave a big lump of holiday coal to Duke Energy and Progress Energy, putting the colossal Carolina utility merger on hold pending an improved plan to mitigate market power. It isn’t clear whether FERC’s latest skepticism about the merger will […]
