A Texas District Court today dismissed two appeals challenging air quality permits granted by the Texas Commission on Environmental Quality (TCEQ) last December for the 600-MW coal-fired Tenaska Trailblazer Energy Center under development near Sweetwater in Nolan County.

CMS Energy Corp.’s Consumers Energy, which has the oldest fleet of coal plants in the nation, with an average age of 50 years, on Friday said it was immediately abandoning plans to build a $2 billion, 830-MW clean coal plant project near Bay City, Mich., and was planning to suspend operations at seven smaller coal-fired units in 2015.

Texas will be short 2,600 MW during the summer 2012 peak, and reserve margins will dip to 12% owing to decisions to mothball some generation units, several delays in planned generation, and a higher load forecast, the Electric Reliability Council of Texas (ERCOT) said on Thursday.

A report unveiled on Monday by the Massachusetts Institute of Technology (MIT) on the future of the smart grid over the next two decades finds that the U.S. grid can stand up to the challenge of integrating electric vehicles as well as new sources of distributed and intermittent power generation—as long as certain policy changes are made.

Last week, as Chairman of the Senate Energy and Natural Resources Committee Jeff Bingaman (D-N.M.) announced he would propose a federal Clean Energy Standard (CES) bill early next year, the Energy Information Administration (EIA) released an impact analysis that examines how such a policy would affect the nation’s power profile and carbon emissions.

Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change.

As China’s economy continues to soar, its energy use and greenhouse gas emissions will keep on soaring as well—or so goes the conventional wisdom. A new analysis by researchers at Lawrence Berkeley National Laboratory now is challenging that notion, one widely held in both the United States and China.

A Romanian lignite-fired power station wanted to minimize the operating cost of the flue gas desulfurization (FGD) system by placing the booster fans in the "wet position," between the wet FGD scrubber and the wet stack, where they would consume significantly less power. A number of combined environmental effects must be considered in this design.

Pulverizers prepare raw fuel for burning by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. Part I of this three-part report examined the essentials of pulverizer design and performance; Part II discussed the importance of fuel fineness. This final article discusses the importance of air and fuel measurement.

The U.S. Environmental Protection Agency (EPA) is expected to release new air quality standards for coal-fired power plants this month. Division in the power industry is encouraging the EPA to set an unachievable compliance timetable.
