Court Remands Air Permit for $3B Texas Coal Plant
A Texas state district judge last week remanded an air permit for White Stallion Energy Center’s 1,320-MW coal- and petroleum coke–fired power plant power plant proposed to be built in Matagorda County to the Texas Commission on Environmental Quality (TCEQ), potentially posing a delay for the $3 billion project.

Spain: A Renewable Kingdom
Spain has served as both exemplar and scapegoat when it comes to renewable energy policy. Though power policy must necessarily accommodate specific national resources and goals, Spain’s experience as an early and eager adopter of renewable energy technologies and subsidies is a cautionary tale of how the best intentions can have unintended consequences.

Applying CFD to Optimize Furnaces Cofiring Biomass, and the Impact of Cofiring on SCR
The international policy framework regulating the emissions of greenhouse gases from industrial and utility boilers is in flux. Meanwhile, most boiler owners are evaluating potential strategies for when, not if, more stringent emissions reduction regulations are put in place. One of the most attractive compliance options is the cofiring of biomass in existing coal-fired boilers.

ERCOT Predicts No Coal Retirements from EPA Rules
In surprising findings, given the state’s often-contentious relationship with the Environmental Protection Agency, a study released May 11 by the Texas grid operator concludes that a suite of looming EPA rules to reduce conventional and hazardous air pollution from power plants and to tighten power plant cooling water regulations likely would not force the retirement of any Texas coal plants.

Southern CEO Sees Federal "War on Coal"; Questions Dash to Gas
In a wide-ranging speech on U.S. electricity policy, Southern Co. Chairman, President, and Chief Executive Officer Thomas Fanning said that coal is "under attack" by the federal government, that natural gas may not be the panacea seen by some utilities facing environmental constraints on their coal plants, and that federal proposals to sharply reduce utility hazardous air pollution have unreasonable compliance deadlines that should be extended.

Turning Gold into Lead
Despite California’s deep economic wounds, Governor Jerry Brown (D) last month signed a bill (SB 2X) that increased the state’s already ambitious renewables portfolio standard (RPS) goal from 20% to 33% by 2020. Together with the state’s Global Warming Solutions Act of 2006, which requires caps on greenhouse gas emissions starting next year, the new law will push up the price of electricity and further delay the Golden State’s economic recovery by permanently driving away irreplaceable businesses and manufacturing jobs.

Seven Charged in Siberian Hydropower Plant Accident
The Russian Investigative Committee has completed a probe into the August 2009 accident at the Sayano-Shushenskaya Hydro Power Plant in Siberia that killed 75 people. The committee has charged seven people—including the plant’s former head, Nikolai Nevolko, his deputies, and the plant’s former chief engineer, Andrei Mitrofanov—for violating safety rules. If found guilty, the officials could face five years in jail.

Germany Considers Accelerated Nuclear Exit on Fukushima Worries
In the wake of the devastating nuclear crisis afflicting the Fukushima Daiichi nuclear plant in Japan, Germany has embarked on an abrupt shift away from nuclear power, shutting down eight reactors for safety checks and ditching concerted efforts to keep nuclear power plants open in the long term. In mid-April, Chancellor Angela Merkel told reporters that leaders of Germany’s 16 states all want to “exit nuclear energy as soon as possible and make the switch to supplying via renewable energy.” The policy reversal has incited ardent opposition from the energy sector and industry.

Air Preheater Uses New Adaptive Brush-Sealing Design
Radial, axial, and circumferential metallic seals installed on rotary, regenerative air preheaters have evolved little from the original metal strip designs that date back to the original Ljungström preheaters developed nearly a century ago. Unfortunately, metallic strip seals degrade soon after installation, allowing excessive air-to-gas leakage, which translates into increased fuel consumption and fan power.
