The conflicting challenges of operating a plant beyond its prime and Exelon’s commitment to manage carbon emissions from its power system are pushing the company’s plant engineers to innovate. An example: Fairless Hills Generating Station was given a complete overhaul and now burns landfill gas that otherwise would be treated as waste.

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.
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.

In chemistry, osmosis refers to the movement of water molecules through a selective membrane from an area of low solute concentration to an area of high solute concentration, creating a pressure gradient. Researchers have recently demonstrated that exploiting this natural phenomenon could produce useful amounts of electrical power.
The wind energy business is beginning to look as frenetic as the merchant gas-fired power business in the late 1990s—with some critical differences. If the 10 issues listed here are addressed soon, wind power may avoid a crash and burn similar to the one that beset the gas turbine business.
Utility resource planners are used to viewing new generation in terms of firm, dispatchable capacity. Dispatching a renewable resource such as wind requires a different perspective. Wind capacity can serve as a hedge against fossil fuel price risks and perhaps future emissions restrictions, but it requires a much more structured planning horizon. Integrating wind farms into their portfolios may be the most difficult challenge utilities face today.
