  • Reducing Ash Agglomeration in JEA’s CFB Boilers

    A chronic operational problem with circulating fluidized bed boilers is ash buildup or agglomeration that turns into slag, which forces frequent shutdowns for cleaning. Solving the problem is tricky, because combustion efficiency relies on good fuel quality, but the best fuel for efficiency may not be the best fuel for minimizing furnace and tube fouling and ash plugging.

  • Why EDF Is Working on Natural Gas

    Many environmental groups are calling for a ban on hydraulic fracturing and are even lobbying to end natural gas development altogether. The Environmental Defense Fund is not. The EDF energy program chief counsel explains why.


  • Are Economics Trumping Regulation?

    The fate of coal-fired generation remains fluid as owners weigh environmental rules, the effect of low natural gas prices, and the shifting cost of investing in emissions control technology. An analysis of generating unit data suggests that smaller, older, less-efficient, and less-frequently dispatched assets are most vulnerable to retirements. Recently accelerated retirement dates for some units indicate that economic factors are a more important determining factor than pending environmental mandates

  • New Study Advocates Shift Toward Long-Term Gas Supply Agreements

    Current low gas prices offer a unique opportunity to lock in savings for years to come—but only if utilities, gas suppliers, and regulators have the vision to commit to a new way of doing business.


  • China’s Power Generators Face Many Business Barriers

    China’s five largest power generators own half of that country’s power generating assets. Faulty policies and the rapidly changing global economy have made it difficult for these companies to fulfill the high expectations arising from enactment of the Power System Reform Scheme of 2002

  • EPA Stalls on Coal Combustion Residuals

    In 2010, the U.S. Environmental Protection Agency (EPA) proposed federal rules regulating coal combustion residuals (CCRs) for the first time to address the risks posed by coal-fired power plants’ disposal of such waste byproducts. The need for new regulations remains a topic of debate, heightened by the EPA’s reticence to release the rule. The EPA says that it will release the new rule by the end of this year–over two years late.

  • Hollow Victory

    Cato Institute senior fellows Jerry Taylor and Peter Van Doren in an Aug. 31 Forbes website blog suggest that the Environmental Protection Agency’s (EPA’s) carbon pollution standard for new coal-fired power plants (Standard) is a meaningless skirmish in President Obama’s “war on coal.” The Standard may have no tangible impact on the industry in the future, but it has great strategic benefit to the administration.

  • Germany’s Reliance on Coal Grows

    This August, instead of the usual fanfare at the official commissioning ceremony of RWE’s twin-unit 2.2-GW coal-fired BoA Units 2 and 3—a $3.3 billion lignite-fired power plant in Grevenbroich-Neurath near Cologne (Figure 1)—Germany’s premier of the state of North Rhine–Westphalia, Hannelore Kraft, and the newly installed federal minister of the environment, Peter Altmaier, requested a rapid cutback in power production. As 400 guests watched, the output of one unit was reportedly reduced by more than 150 MW in five minutes, and then restored just as fast. The demonstration was to show how quickly the plant could offset the intermittency of wind and solar power, the officials said, proclaiming the plant an “important element” of Germany’s energy strategy.
