Safety Implications of Coal and Biomass Fuel Mixes
Practically everyone would agree that the energy policy of the U.S. is in a great state of flux. Not since the introduction of commercial nuclear power some five decades ago has our country come to such an energy crossroads. No matter what your political ideology, no one can refute that conventional coal-fired power plants are being paralyzed by recent and potential U.S. Environmental Protection Agency (EPA) regulations designed to cut the nation’s reliance on coal.

When Successful Procurement Policies Fail
California is approaching a tipping point with respect to the near-term economic viability of existing non-utility generation. The procurement policies and practices implemented in response to the statewide energy crisis over a decade ago have evolved into market conditions that do not offer “uncontracted” existing resources with sufficient and stable enough revenue streams to recover going-forward costs. Continued adherence to these policies will subject such resources to an increasing risk of economic retirement, threatening long-term reliability and potentially costing electric consumers billions of dollars.

Optimizing Catalyst Performance Lowers O&M Costs
Santee Cooper’s Cross Station has implemented a catalyst optimization program that reduces catalyst replacement cost while maximizing catalyst performance. This case study illustrates the economic advantages of taking a holistic approach to optimizing unit catalyst performance by controlling slag, fouling, sulfur trioxide, and ammonium bisulfate—key factors that lead to premature shortening of catalyst life. With catalyst costing $2 million a layer and up, there is plenty of economic motivation to find ways to improve its life.

Federal Court Rejects Challenges to EPA Industrial, Automotive GHG Rules
A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on Tuesday ruled that the U.S. Environmental Protection Agency (EPA) was "unambiguously correct" in its interpretation of the Clean Air Act (CAA) to regulate carbon dioxide emissions. The federal agency’s endangerment finding that greenhouse gases (GHG), including carbon dioxide, are a threat to public health and welfare, and its decision to set limits for industrial and automotive emissions of GHGs, was "neither arbitrary nor capricious," the court ruled. The court, however, found that it lacked jurisdiction to review the timing and scope of the GHG rules that affect larger stationary sources, including new coal-fired power plants.
