Burning spot market fuels can reduce plant fuel costs, but it can also introduce unexpected operational problems throughout the boiler island. Orlando Utilities Commission’s Stanton Energy Center optimized its Unit 2 combustion system and improved O&M practices as part of a project to increase the unit’s fuel flexibility without degrading reliability or heat rate. OUC’s attitude: If you can measure it, you can manage it.

I believe there are three basic objectives for the energy industry in the modern era. First, to provide a reliable and ample supply. Second, to ensure that the supply is provided at the least cost to consumers. And third, to accomplish the first and second objectives with the least possible adverse effects on the environment. […]

Charlton Heston’s legacy will surely rest on his iconic performance as Moses in The Ten Commandments and his unwavering support of the Second Amendment. I had the privilege of watching a classic Heston performance at the 2000 National Rifle Association convention in Charlotte, N.C., when he raised a handmade Brooks flintlock above his head and […]

Until very recently, common wisdom held that the price of renewable energy would fall as legislative procurement mandates ensured its long-term demand. The resulting growth in supply and sales would spur investment in the field, create economies of scale, and accelerate progress down the technology learning curve. Something unexpected, however, happened along the way. Though […]

Perhaps the biggest shortcoming of wind power is its unreliability. Unconcerned with human needs, Mother Nature has decided that the wind usually blows strongest at just the wrong times, when electricity demand is lowest. However, using savvy negotiations to exploit a new provision in California’s renewable energy regulatory regime could make wind power more dispatchable during peak-demand periods and increase the capacity of wind farms at the same time.

This February, a federal appeals court tossed out the Clean Air Mercury Rule and its cap-and-trade program and ordered that mercury be regulated more stringently as a hazardous air pollutant. Adding insult to injury, the court made its ruling effective one month later. While the EPA regroups, state energy and environmental regulators will have an opportunity to look closely at recent power plant permits for guidance. This article reviews the technology options and regulatory approach for mercury control used on recently permitted and currently operating coal-fired plants.

The ability to detect contaminated feedwater or steam before it can corrode the internals of a turbine or HRSG and cause a forced outage is worth millions. One knock against cation conductivity monitoring—still the most common technique for the early detection of contamination—is the difficulty of interpreting conductivity readings when the plant’s makeup contains significant levels of organics or CO₂. Here are the pros and cons of cation conductivity monitoriting and some alternative monitoring methods.

Modern predictive maintenance systems can monitor the health of most plant equipment. By sorting through the wealth of information those systems deliver, operators can discern important trends, including the early signs of a system or component failure.
