As emissions caps drop, technological solutions must become increasingly effective and efficient. Researchers, equipment vendors, and plant operators are exploring alternatives to SCR and SNCR, with a view to reducing the overall costs of NO_x reduction. They’ve also achieved 95% to 99% removal of SO₃, with no visible plume opacity.

February 1885 The cover story examined the latest in reciprocating engine technology: the Greene automatic cut-off engine (Figure 1). Here is how the editors described it: “The engine has a girder frame; guides case separate and dowelled and bolted to the bed plate; four-part main boxes; Porter governor. There are two steam and two exhaust […]

Federal Energy Regulatory Commission (FERC) Order No. 689, issued on Nov. 16, 2006, established requirements and procedures for granting permits to build transmission facilities within “national interest electric transmission corridors” designated by the U.S. Department of Energy (DOE). After summarizing the statutory and regulatory background, this opinion piece addresses jurisdictional conflict between FERC and states, […]

TIME magazine’s selection of a Person of the Year often is unusual enough to be covered in other publications. In most years, the pick has been fairly predictable: a high-profile foreign or domestic politico playing high-stakes poker with our collective futures. In others, TIME has stretched the definition of “person”—such as in 1982 (the computer), […]

U.S. demand for natural gas is projected to increase by more than 50% by 2020. Companies are building—and the public is opposing—receiving terminals on three coasts that would increase imports of liquefied natural gas. The pros and cons of “opening up” Alaska, coastal waters, and federal lands to drilling are still being debated. These politically […]

Forecasting the direction of the U.S. electric power industry for 2007, much less the distant future, is like defining a velocity vector; doing so requires a direction and speed to delineate progress. In this special report, POWER’s first stab at prognostication, the editors look at current industry indicators and draw conclusions based on their more than 100 years of experience. To borrow verbatim the title of basketball legend Charles Barkley’s book: I May Be Wrong but I Doubt It.

Following the money invested in projects is a viable way to compare growth trends for power projects using the four major generation types: coal, natural gas, nuclear, and renewable.

One expert has called it the "digital delta"—the seemingly endless challenges in refurbishing U.S. nuclear plants with digital instrumentation and controls. But it appears more like a deep ditch, where even those seeking to license new reactors could get stuck. Here’s the latest on the issues, experience, and results—plus recommendations for getting the industry out of the mud and back on the road.
