The Trump administration has proposed an overhaul of U.S. power plant emissions rules, unveiling a plan that would allow individual states to determine how they will regulate pollutants. The proposal, called the Affordable Clean Energy (ACE) plan and discussed during the keynote address at the MEGA Symposium in Baltimore, Maryland, on August 21, would essentially dissolve […]

It is safe to say that every power plant in the world uses scaffolding in some way, shape, or form. It is a critical component for many maintenance activities where permanently installed access is not possible or practical. Therefore, the dangers associated with scaffolding should not be overlooked by the industry. Often, plant maintenance personnel […]

For a decade or more, heat recovery steam generator (HRSG) users have heard that Grade-91 tubing (T-91) is susceptible to microstructure damage from improper heat treatment. Now, a new damage mechanism in T-91 tubing has been identified, which HRSG users heard about at the February 2018 HRSG User’s Group Conference. During the discussion on heat […]

NRG Energy will not restart its Dunkirk power plant in western New York, with the company on July 11 saying the cost to reconnect the facility to the state’s electric grid prohibits reopening the retired coal-fired plant as a natural gas-fueled facility.

There are often multiple closed-loop water cooling systems installed in a power plant. Chances are good that they cool or control temperature on some very critical components. It can be easy to ignore these systems because they are usually quite reliable. By its very nature, when a closed-loop system remains closed and operates properly for an extended period of time, it is often […]
