Many informative articles have been published about options for treating flue gas desulfurization wastewater, but new technologies are rapidly changing the treatment possibilities. This article reviews key economic considerations and introduces an innovative treatment solution that lowers costs and the amount of waste generated. Flue gas desulfurization (FGD) wastewater varies widely depending on the source […]

Cooling towers serve the vital role of cooling water for power plant heat exchange equipment. Sustaining excellent system performance is important because a one-degree increase in water temperature can cause a 2% increase in energy usage. Proper maintenance and a few upgrades could improve a cooling tower’s efficiency, while also saving water in the process. […]

Using reclaimed water as a makeup supply for cooling tower systems has become a popular option for reducing impacts on local water resources, but it comes with its own challenges because of its unique

Power generation need not be another source of strain on diminishing freshwater resources. Well-established water reclamation technologies are enabling producers to conserve resources—and money. Meeting the

Risk is inherent in all businesses, but power plants face unique perils that require the right protection. Property and casualty insurance may not be enough; equipment breakdown, business interruption, weather risk transfer, and cyber coverage are just a few examples of insurance that may also be worth considering. The right coverage could mean the difference […]

The boom in renewable energy, spurred by dramatically falling costs, has led some experts and political figures to begin talking seriously about what was once science fiction: A world powered entirely by renewable generation. But is it truly feasible or economic? One series of studies suggests it is—with some important caveats. In the first half […]

California’s excess of solar power challenges the statewide independent system operator’s ability to balance its system without curtailing low-carbon supplies and ramping up natural gas generation. It’s
