A proposed rule issued in late February by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.

It has been said that a picture is worth a thousand words. However, photos of the conflagrations that have resulted from ignition of minor lube oil leaks on a typical steam turbine room floor will leave you speechless. Full-scale physical simulations of oil fires by the insurance company FM Global leave no doubt that power plant fire prevention and mitigation is a judicious blend of art and science.

This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal.

Moving into the election season, President Obama has again pointed to the number of green jobs supposedly created by his administration in a recent campaign advertisement, although the claims are not supported by available data. Now, other government authorities are using the same poor data as an excuse to increase spending.

Advanced ultrasupercritical (A-USC) is a term used to designate a coal-fired power plant design with the inlet steam temperature to the turbine at 700C to 760C. In Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.

NRG Energy last week filed a notice of intent with the New York Public Service Commission (PSC) to mothball Units 1, 2, 3, and 4 of its 635-MW Dunkirk coal-fired power plant near Buffalo, N.Y., by September this year until market conditions improve.

The Federal Energy Regulatory Commission (FERC) last week conditionally approved an enforcement approach proposed by the North American Electric Reliability Corp. (NERC) that allows industry to self-report “low risk” reliability standard violations. The initiative will “free up resources and attention to address more serious risks to reliability,” FERC said in its decision.

An agreement reached between the Federal Energy Regulatory Commission (FERC) and Constellation Energy Commodities Group will require the company to pay $245 million to settle FERC allegations that the company manipulated power markets run by the New York Independent System Operator (ISO) and ISO New England between September 2007 and December 2008. The penalty is the largest ever imposed by FERC under the expanded enforcement authority assigned to the federal body in 2005.

Cap and trade programs to reduce emissions do not inherently provide incentives to induce the private sector to develop innovative technologies to address climate change, according to a new study from the Lawrence Berkeley National Laboratory in the journal Proceedings of the National Academy of Sciences.
