“Dash to Gas” Foreshadows Problems Ahead, Says Report
The shift toward greater reliance on natural gas for power generation is not just a story of greater efficiency and lower emissions. There are also lurking risks to reliability unless the natural gas and electricity industries can plan carefully for the future.
Duke Continues Switch from Coal with Three New Gas Plants
Duke Energy’s once coal-heavy fleet is making a big transition to gas. Two new advanced combined cycle plants, and a third set to start up later this year, are a key part of the North Carolina–based firm’s drive to modernize its portfolio.
How Overcycling Induces Economizer Tube Failures
Why do some HRSG economizers and feedwater preheaters seem to suffer tube failures more frequently than others? If frequent failure is your problem, the cause may not necessarily be your heat exchanger’s design or how often you cycle your plant. Don’t forget to carefully check your feedwater controls—they may be cycling more than your HRSG.
Measuring Fugitive Methane Emissions
Understanding the true rate of methane leakage in natural gas production and consumption is a key milestone in managing this bridge fuel. But despite recent reports, there’s still a ways to go before we have a full picture of what’s going on.
More Duty for Gas Plants as Wind Turbine Output Declines?
>Gas-fired power has a growing and well-established niche in providing load-following for wind farms. But two recent reports suggest the demand on these plants may be greater than anticipated, as long-term output from wind may be falling short of original projections.
