Geothermal energy has been around forever, used as a heating source across the world. Today it has surfaced as another renewable resource, with advancements in drilling technology bringing down costs and opening new areas to development. In conjunction with the feature article on geothermal in the May 2019 issue of POWER, we sought opinions from […]
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 National
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 other
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 plants, deeming them “unlawful.” The decision adds a dramatic new element of uncertainty in timing of the rule, which the Trump administration has said it […]
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
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
