Strained water resources across the world necessitate innovative ways for power plants to more efficiently use, and reuse, the water that is available. At the U.S. Department of Energy’s Argonne…

Technical, legal, and regulatory articles on water-related topics for power plants: cooling, wastewater, intake, chemistry, purge water, and once-through systems
Evolving environmental regulations have forced many coal power plant operators to re-evaluate how they handle water and ash. Many units have been retrofit with dry handling systems, but there are…
In a legal victory for environmental groups, a federal court has vacated key portions of the Environmental Protection Agency’s (EPA’s) November 2015-promulgated effluent limitations guidelines (ELGs) for steam electric power…
The Umm Al Houl combined cycle power plant in Qatar has been inaugurated by Siemens, delivering almost a quarter of the country’s installed power generating capacity and providing up to…
An estimated 91% of U.S. coal power plants that submitted groundwater monitoring data as required by the Environmental Protection Agency’s (EPA’s) 2015 Coal Combustion Residuals (CCR) rule have unsafe levels…
Energy supplies are tight in the Pacific Northwest, a region that has been stricken with unseasonably frigid weather and is bracing for deep freezes as a mass of Arctic air…
Water quality monitoring and control are two of the most critical operations that power plants employ to protect assets, such as boilers and steam turbines, from corrosion by assuring the…
One of the largest hurdles to delivering substantial amounts of renewable energy is transmission constraints. Los Angeles’ current in-basin transmission infrastructure is based largely on delivering power from coastal power…
It is fairly common for power plant engineers and maintenance managers to focus on fireside issues rather than waterside issues during routine maintenance outages. However, that could be a mistake.…
Thermohydraulic simulations can provide detailed heat recovery steam generator (HRSG) data to help determine the root cause of failures, predict the degree of wear from various mechanisms, and assess the…
