Congress’s enactment of the Public Utility Regulatory Policies Act of 1978 (PURPA) triggered a revolution in the development and construction of power plants. PURPA’s creation of an independent class of generators—qualifying facilities (QFs)—exposed a century-old economic myth that had justified restricting ownership of generating facilities to governmental and investor-owned utilities (IOUs). The success of QFs […]

Scientific debate on the validity of global warming science continues, but the issue has yet had little impact on individuals. That impact is being negotiated in Washington, where a regulatory framework that would mandate reductions of greenhouse gases (GHGs) is taking shape. Legislative options under consideration would redefine what power plants must do-and not do-to […]

There are often five stages to enacting major legislative reforms: Initial enthusiasm, a sobering recognition of the complex issues to be solved, excruciating negotiations over those issues, hand-to-hand combat with supporters of the status quo, and resignation that the final product only deals with part of the problem. Congress has reached Stage 2 as it considers a cap-and-trade system for reducing carbon emissions. Now the real work begins.

The latest benchmarking study by the EUCG examines the technology and costs of 49 flue gas desulfurization systems currently under design or construction by 12 of the nation’s largest utilities. Although the study’s detailed results are proprietary to EUCG members that participated in it, POWER was given access to the top-level findings. To get details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.

The U.S. Department of Energy (DOE) and Great River Energy are testing a new coal-drying technology that could dramatically reduce the emissions of lignite-burning power plants. The project was selected for funding during Round I of the DOE’s Clean Coal Power Initiative (CCPI), a series of competitions to demonstrate a range of promising clean-coal technologies. […]

Are you using your flue gas desulfurization (FGD) system to its highest potential? You might not be if you’re not making it do double duty. It seems that million-dollar wet scrubber you installed to rid your flue gases of sulfur dioxide also can do a decent job of capturing mercury — under the right conditions. […]

If little else is clear about the future of the U.S. power industry, this much is: Electricity rates are going up across the country, and will continue to. None of the esteemed panelists at the CEO session of the ELECTRIC POWER 2007 Conference & Exhibition in Chicago last month actually said those words. But much […]

In a carbon-constrained world, CO2 capture and storage (CCS), although considered the most radical of the carbon abatement technologies (CATs), seems to be favored over combustion and steam cycle improvements alone. However, CCS is the least commercially developed of the CAT options; at present, there are only field prototypes for its various forms. Nonetheless, most […]
