Today’s heat recovery steam generators (HRSGs) are suffering reliability problems, mainly because they’re being operated in the cycling mode instead of the baseload mode for which they were designed. The good news is HRSG suppliers are adapting to the market demands and are designing the next generation of HRSGs to have cycling-friendly—also called fast-start—features. One […]
After flowering between 2008 and 2014, power from biomass has withered in the face of market forces. Furthermore, lawmakers in Washington, D.C., have resisted regulatory action that could boost the industry
A pilot project was initiated by China’s largest energy provider to test the effectiveness of fog-based power augmentation for a gas turbine at a compressor station. The system provided a significant
Coal-fired plants have been powering the electric grid for more than a hundred years, but the technology being used in them is not stagnant, as many advancements have been made. One new design—the Clean
Community solar projects, also known as solar farms or solar gardens, are maturing and moving forward. Minnesota leads the nation with 559 MW of capacity on the ground, and other states are following with new
The numbers tell the story of how the addition of selective catalytic reduction (SCR) technology helped an iconic New Mexico coal-fired plant reduce its emissions, keeping the plant in operation and continuing
A new coal-fired combined heat and power (CHP) plant at the University of Alaska-Fairbanks, replacing old boilers in place since the 1960s, improves the efficiency of the campus’ heating and cooling system
State-of-the-art automation systems are common at power plants these days. Still, many plants start up units in a very manual way. When startups were rare, the implications were minimal, but as units cycle
New coal power plant technology is being developed by various companies around the world, but there are some pretty efficient and reliable designs already commercially available. Circulating fluidized bed
A team that reviewed Southern Nuclear Company’s (SNC’s) April 2019 Vogtle Units 3 and 4 Re-baseline of Forecast Schedule and Cost said it believes the working schedule predicated on commercial operation dates of May 23, 2021, and May 23, 2022, for the respective units, is unachievable. Furthermore, the reviewers said the regulatory-approved schedule from the […]
