Turning the corner on global warming

In his keynote speech this May to the Global Roundtable on Climate Change, held in Iceland and hosted by the Earth Institute of Columbia University, Ólafur Ragnar Grimsson—the president of…


Shaving load peaks from the substation

As load growth on U.S. transmission and distribution grids continues to shrink reserve margins nationwide, utilities are looking for new ways to meet demand peaks. Until recently, the most elegant…


Monitoring key gases in insulating oil keeps transformers healthy

U.S. electricity consumption continues to increase almost 2% annually. As the load growth spurs calls for new power plants and transmission lines, it's easy to forget the impact of the…


Meeting utility industry challenges through innovation

Noted management consultant Peter Drucker once wrote that "an established company, which, in an age demanding innovation, is not able to innovate, is doomed to decline and extinction." Some say…


Technology options for capturing CO2

If the U.S. regulates CO2 emissions in the future, the power generation industry is likely to be a prime target. As the table shows, electricity production accounts for nearly one-third…


Utilities split on readiness of IGCC

Resource planners at electric utilities have never had it so good—or bad. On the one hand, planners have never had more technology options for building needed generating capacity at their…


Expert systems optimize boiler performance, extend plant life

All coals contain mineral matter in their ash. Slag deposits form when molten or sticky particles of flyash are quenched upon contact with furnace walls or other radiant surfaces. The…


Designing and upgrading plants to blend coal

Although coal continues to fuel about 50% of U.S. electricity production, coal-fired generation has spent the past few years in the wilderness. Burning coal has become synonymous—at least in public…


Apply the fundamentals to improve emissions performance

Controlling combustion often has been likened to a black art rather than a science. The physics of burning coal are as well understood as the design of steam generators. The…


Restricting bids for new capacity raises costs, lowers reliability

Most sponsors of bid solicitations seek to attract the maximum number of high-quality bids. Basic economic principles tell us that the greater the number of respondents to a solicitation, the…


Focus on O&M (October 2006)

INSTRUMENTATION & CONTROLS Upgrading to digital--twice The E.W. Brown Generating Station of Kentucky Utilities (KU) is located in the town of Burgin, about 30 miles southwest of Lexington. The plant's three generating…


Global Monitor (October 2006)

Consult the Guinness Book of World Records if you want to know which monster truck has made the highest jump ("Bigfoot 14"—24 feet) or the length of the longest freight…


Balancing risks and rewards

More top utilities are making plans to add one or more integrated gasification combined-cycle (IGCC) plants to their generation portfolios over the next decade. Some 25 separate projects are on…


SO3’s impacts on plant O&M: Part I

The visible consequences of sulfuric acid aerosol emissions—opaque stack emissions called "blue plumes"—are merely the tip of an iceberg. In sufficient concentration, SO3 also can increase corrosion and fouling of…
