A New Regulatory and Environmental Milieu

POWER Magazine :: Power plant environmental monitoring and control issues >> 
There will be no shortage of important issues to keep utility executives and their staffs busy throughout 2010. Few of these will be surprises, although a number will emerge quickly and assume larger-than-life significance. The confluence of the great recession and the sturm und drang of environmental legislation will create the liveliest of the debates, but more subtle trends will drive additional stressors. The results of Black & Veatch’s 2009 fourth annual industry strategic directions survey can offer guidance as to how these issues will affect the industry in the coming year....

GHG Emissions Reporting Begins Jan. 1

POWER Magazine :: Power plant environmental monitoring and control issues >> 
Last fall, the U.S. Environmental Protection Agency (EPA) issued a rule creating a mandatory national system for reporting greenhouse gas (GHG) emissions. The agency requires regulated entities to begin monitoring GHG emissions January 1, 2010, and to submit their first annual emissions reports March 31, 2011. This is a key step toward federal regulation of GHG emissions (a step that may have major implications regarding "major sources" and permitting requirements for new sources). It’s also an opportunity for power producers to implement their inventory management plans....

Which Country’s Grid Is the Smartest?

POWER Magazine :: Power plant environmental monitoring and control issues >> 
The U.S. isn’t the only country evaluating and implementing elements of smart grid technology. In fact, it could be argued that other nations are much farther along the path to a comprehensive, technically advanced system for integrating renewables, managing load, and creating a more flexible power grid....

The U.S. Gas Rebound

POWER Magazine :: Power plant environmental monitoring and control issues >> 
"It’s déjà vu all over again," said Yogi Berra. The Hall of Fame catcher could easily have been predicting the coming resurgence of natural gas – fired generation. Yes, a few more coal plants will be completed this year, but don’t expect any new plant announcements. A couple of nuclear plants may actually break ground, but don’t hold your breath. Many more wind turbines will dot the landscape as renewable portfolio standards dictate resource planning, but their peak generation contribution will be small. The dash for gas in the U.S. has begun, again....

The Impact of Carbon Trading on Performance: What Europe’s Experience Can Teach North American Generators

POWER Magazine :: Power plant environmental monitoring and control issues >> 
The European carbon trading system experience suggests that North American generators should expect severely altered coal-fired power plant operating profiles if cap-and-trade legislation becomes law. In a groundbreaking study, Solomon Associates predicts the reduction in mean run time that North American generators should expect. The trends outlined in this study provide an overview of some of the broad challenges facing generators in moving to a carbon-constrained market environment....

Regulations and Economics Drive Wet FGD Upgrades

POWER Magazine :: Power plant environmental monitoring and control issues >> 
Today’s coal-fired power plants face the twin challenges of improving their wet flue gas desulfurization (FGD) systems’ emission control capabilities in order to comply with environmental regulations while at the same time cutting their operational and maintenance costs. Smart strategies for retrofitting existing FGD systems can help plant personnel meet both of these objectives....

New Process Transforms Waste into Product for Controlling Emissions

POWER Magazine :: Power plant environmental monitoring and control issues >> 
In April, Solvay Chemicals Inc. commissioned a new facility that uses an innovative process to recover and transform sodium carbonate waste streams into a market-grade sodium bicarbonate used in air emissions control....

Climate Change: Avoid Political Thickets

POWER Magazine :: Power plant environmental monitoring and control issues >> 
A federal judge recently dismissed a lawsuit in which the plaintiffs alleged that defendants’ production of chemicals and electricity had “added to the ferocity of Hurricane Katrina.” The judge’s reasoning reveals the inherent limitations of courts unilaterally initiating policies to address climate change issues....

Determining AQCS Mercury Removal Co-Benefits

POWER Magazine :: Power plant environmental monitoring and control issues >> 
The U.S. Environmental Protection Agency is expected to propose an emissions standard for mercury and other hazardous air pollutants emitted by coal- and oil-fired electric generating units in March of 2011. The anticipated rule would require emission control to meet the various standards using maximum achievable control technology, as determined by the prescriptive requirements of the Clean Air Act. In response to the expected rule-making, utilities will be required to make technology decisions in order to ensure compliance. One cost-effective approach to compliance may be the use of “co-benefits” from air quality control systems (AQCSs) already in service that are designed to remove other pollutants....

ReACT Reduces Emissions and Water Use

POWER Magazine :: Power plant environmental monitoring and control issues >> 
Regenerative activated coke technology (ReACT) is an integrated multipollutant control approach that removes SOx, NOx, and Hg from coal-fired plants by adsorption with activated coke to attain emissions levels found at natural gas–fired plants. One big advantage of this technology is that it uses only a fraction of the water used by conventional wet flue gas desulfurization. A recent license agreement brings this technology to the U.S....
