U.S. wind power is on a roll, with wind farms sprouting like weeds. But in the near future, utilities may end up paying higher prices for wind capacity because state regulators are, in effect, imposing an artificial floor on national demand for generation fueled by renewable resources. At last count, at least 20 states had […]

The California Energy Commission (CEC) recently awarded about $14 million for carbon sequestration projects to be overseen by the West Coast Regional Carbon Sequestration Partnership. Westcarb, as the partnership is known, is part of the U.S. DOE’s effort to deploy technologies through its Regional Carbon Sequestration Partnership (RCSP) program. New members Alberta and British Columbia […]

A multitude of variables must be accounted for during the design and development of a wet-stack flue gas desulfurization system. The five-phase process detailed below has proven effective on more than 60 wet-stack system design studies. A basic understanding of these concepts will help inform early design decisions and produce a system amenable to wet operation.

The 35th birthday of the Environmental Protection Agency (EPA) passed last December 2 with little fanfare. EPA Administrator Stephen L. Johnson noted at the time that, "Over the last three and a half decades, through the use of innovative and collaborative approaches to environmental protection and a commitment to responsible stewardship, we have made remarkable […]

Enforcement and (re)interpretation of the Clean Air Act’s new source review (NSR) rules will likely come into focus later this year as many of the key lawsuits against electric utilities are resolved. "It’s going to be a big year for NSR whether you’re a litigator, regulator, lawmaker, or member of the industry," says Tom Sansonetti, […]

For more than 70 years, Steam Plant Operation (Figure 3), published by McGraw-Hill Professional (like Platts, the publisher of POWER, a division of The McGraw-Hill Companies Inc.), has been the bible of steam plant system design, installation, operation, maintenance, and repair. The new eighth edition of this classic reference book is now available.   3. […]

Abating the emissions of power plants is a very hot topic these days. So it’s not surprising that people are coming up with innovative ways to not only cut emissions but also make money from them. The latest brainstorm comes from—where else—the Massachusetts Institute of Technology, where Moshe Alamaro, an atmospheric scientist, has come up […]

Several advanced battery technologies tailored for utility applications have doffed their white coats and donned hard hats. These new bulk energy storage devices, which can almost instantly shave peaks and shift loads, are the answer to the dreams of T&D system designers and operators. Finally, years of R&D in electrochemistry are beginning to pay dividends in the field.
