Proposed U.S. Environmental Protection Agency rules and a greater reliance on newer generation technologies have put the nation’s aging fossil-fueled generation units at risk of retirement. The numbers demonstrate that the U.S. power generating fleet is older than you may believe.

Among the surprises in President Barack Obama’s second Inaugural Address on Monday was his promise to address the challenges of climate change and sustainable energy. An independent draft report released about a week earlier on climate change and its impacts in the U.S. may have helped to fuel his renewed resolve on these intertwined issues.

A settlement reached with the Environmental Protection Agency (EPA) and the Department of Justice to resolve alleged violations of the Clean Air Act will require Wisconsin Public Service (WPS) to invest about $300 million in pollution control technology, pay a civil penalty of $1.2 million, and spend $6 million on environmental mitigation projects.

Shale gas production continues to surge as demand for cheap gas grows. But will state and federal regulation and a wave of local bans choke off the boom?

Environmental Protection Agency Administrator Lisa Jackson on Thursday announced she would step down after President Obama’s state of the union address later this January.

The California Air Resources Board (CARB) recently kicked off a new era in its cap-and-trade program designed to reduce greenhouse gases (GHG) when it held its first GHG emissions allowance auction on November 14. While CARB pronounced the auction a success, the low price and lukewarm demand for allowances evidences market reticence to fully embrace the program.

Achieving a balance between affordable and sustainable electricity while improving reliability is a challenge unlike any the electricity sector has faced since its inception. Technology innovations in key areas such as energy efficiency, smart grid, renewable energy resources, hardened transmission systems, and long-term operation of the existing nuclear and fossil fleets are essential to shaping the future of electricity supplies.

The Environmental Protection Agency (EPA) on Friday issued a final rule that strengthens its National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM2.5) to 12.0 micrograms per cubic meter (μg/m³) but declared it would not finalize a proposal to update separate secondary PM2.5 standards. The final rule’s issuance was lauded by environmental and public health groups, though industry groups opposed it, citing concerns that nonattainment areas would suffer economic setbacks.

Major oil and gas production company Vintage Production California and its subsidiary OXY USA last week agreed to pay $34,000 to resolve the Environmental Protection Agency’s (EPA’s) first greenhouse gas (GHG) permitting violation case.

Texas could again see tight power supplies in the summer of 2013 and beyond—with reserve margins dropping to 2.8% by 2022—even though the outlook has improved, the Electric Reliability Council of Texas (ERCOT) warned in its latest long-term outlook released on Monday.

The Natural Resources Defense Council (NRDC) on Monday made public a proposal that calls for the Environmental Protection Agency (EPA) to use its authority under the Clean Air Act (CAA) to set greenhouse gas (GHG) emissions standards for existing power plants. The NRDC approach would have the EPA create “systemwide standards” rather than ones based on individual generating units.

U.S. Environmental Protection Agency efforts to regulate mercury emissions from coal- and oil-fired power plants have spanned nearly two decades. In February of this year the agency promulgated the Mercury and Air Toxics Standards, but changes to the standards continue.

Coal used for power generation has been the cornerstone of economic development, social progress, and a higher quality of life around the globe and is now fueling the 21st-century economic miracle rapidly unfolding in China. Meanwhile, China is leading the world in coal-fired plant efficiency and the deployment of clean coal technologies.

Duke Energy said  in mid-October that testing was under way in preparation for commercial operation next year of its 630-MW integrated gasification combined cycle (IGCC) Edwardsport power plant in Knox County, Ind.

A bipartisan delegation of lawmakers from Pennsylvania on Oct. 15 urged the Environmental Protection Agency (EPA) to consider creating a separate subcategory for power plants that convert coal refuse into energy in its final Mercury and Air Toxics Standards (MATS). Though waste coal plants made an important environmental contribution by reducing coal refuse piles, the hydrochloric acid (HCl) standard in the MATS rule could push them out of business, they said.

The Environmental Protection Agency (EPA) on Oct. 5 appealed a federal court decision handed down on Aug. 21 that vacated the agency’s July 2011–finalized Cross-State Air Pollution Rule (CSAPR) because, the court said, it violated federal law. The EPA is now seeking a rehearing en banc that would involve all eight judges that serve at the U.S. Court of Appeals for the D.C. Circuit.

This synopsis of today’s most interesting research related to power generation gives you a glimpse of what’s possibly coming to your plant in the not-so-distance future. Research under way today will surely determine how power plants are designed, operated, and maintained for many years to come.

A reconsidered proposal issued by the U.S. Environmental Protection Agency (EPA) on Friday sets out slightly weakened emission limits for mercury, particulate matter (PM), acid gases, and certain individual metals for future coal- and oil-fired power plants.

A decision by the Environmental Protection Agency (EPA) to impose new pollution limits on three coal-fired power plants in Arizona on Friday drew criticism from state officials, who said that the costly measure, which overrides the state’s regional haze plan, is designed to protect visibility, not public health.

In a project funded by the U.S. Department of Energy’s (DOE’s) Office of Fossil Energy (OFE), researchers at The Ohio State University have developed what they call a groundbreaking new hybrid membrane that combines the separation performance of inorganic membranes with the cost-effectiveness of polymer membranes.
