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 of one or more contaminants, a collaborative analysis of the monitoring data by several environmental groups suggests. The March 4 report is significant because power […]
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 descends on the region. The Bonneville Power Administration (BPA), a federal power marketer that sells wholesale power from 31 federal dams and one nuclear […]
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
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 correct addition of
Hydroelectric power doesn’t get much attention in today’s discussions of how to generate electricity, particularly in a world looking to boost renewable technologies such as wind and solar. But the oldest
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. Waterside
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
A new system to remove dissolved (ionic) mercury, along with other contaminants, from power plant wastewater is being developed. It is free of the drawbacks of using a traditional stannous chloride reagent
Many combined cycle power plants have established a pH guideline between 9.6 and 10.0 to minimize corrosion in heat recovery steam generators and condensers. Neutralizing amines are used to achieve these pH
What is the best way to construct a complete chemical-feed system for use in a power plant—piecing together equipment acquired from a hodgepodge of suppliers or creating a system with components sourced from
