From success stories to war stories, members of the Women in Power Panel Discussion shared their insights about working as women professionals in the U.S. electric power industry at the 2012 ELECTRIC POWER Conference in Baltimore on May 16. The gathering featured lively exchanges between panelists and a large number of attendees (Figure 4). The panel discussion was organized by co-chairs Angela Neville, JD, senior editor of POWER, and Colleen Campbell, business development director at CH2M HILL.

The environmental push for renewables and mandates to force them into existence are rightly facing some serious headwinds. The American Renewable Energy Production Tax Credit Extension Act of 2011 foundered in Congress, and more states are experiencing significant power rate increases to cover renewable energy production costs. While renewables are generally not ready for prime time in large quantity on today’s power grid, that doesn’t mean environment concerns ought to be trashed, especially when a more effective off-the-shelf solution is available.

By Kennedy Maize (@kennedymaize) Washington, D.C., 31 July 2012 – What to make of the two successive, horrendous electric power failures in India? The smart money avoids conclusory leaps. When the first cascading blackout hit on Monday, there was much media chatter about generating capacity. The implication was that the outage was demand-driven. But there […]

Wisconsin Power and Light (WPL) Co. plans to retire three of its oldest and smallest coal-fired generating units and invest $1.4 billion into the company’s generating fleet over the next five years to ensure it will be able to manage "current and emerging environmental regulations," the Alliant Energy Corp. subsidiary announced on Friday.

A lawsuit filed in federal court on Friday by Pennsylvania’s Department of Environment Protection (PDEP) alleges that FirstEnergy’s Little Blue Run Dam coal ash impoundment pond in Beaver County, a facility that stores coal ash from the generator’s 2,470-MW Bruce Mansfield coal-fired power plant in Shippingport, Pa., has leached heavy metals in drinking water supplies and surface water. A proposed consent decree could force the generator to shut down the impoundment facility.

But there was nothing particularly unusual […]

The Department of Energy (DOE) on Thursday announced it would award $7 million to eight projects to advance the development of transformational oxy-combustion technologies capable of high-efficiency, low-cost carbon dioxide capture from coal-fired power plants. Leveraged with recipient cost-sharing to support about $9.4 million in total projects, the awards are expected to support the development and deployment of “carbon capture, utilization, and storage (CCUS)” by focusing on further improving the efficiency and reducing the costs associated with carbon capture.

The Bureau of Labor Statistics has released another report on green jobs. According to the BLS, an oil industry lobbyist could be considered as having a green job. The report’s definitions still lack common sense.

Announcements about coal plant retirements have become commonplace. Are new EPA rules completely to blame, or are there other power market pressures at play?

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 the first two parts of this three-part report, we introduced the A-USC boiler and the metallurgical advancements required for the A-USC boiler to operate at such high temperatures. This final report explores the A-USC boiler’s unique design challenges.

Complying with air emissions rules doesn’t always require construction of a scrubber or SCR. Finely ground trona has proven to be very successful at economically removing SO₃, SO₂, and HCl from stack gases.

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on June 26 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.

In response to a court order, the U.S. Environmental Protection Agency (EPA) proposed updates on June 15 to its national air quality standards for harmful fine particle pollution, including soot (known as PM2.5). The agency says that 99% of U.S. counties are projected to meet proposed standards without any additional actions.

Natural gas-fired generation enjoyed a competitive advantage through this past winter and spring as historically low prices for the commodity combined with mild weather and relatively light demand to turn the dispatch stack on its head and favor gas over coal. That advantage is narrowing as summer demand approaches. A senior market analyst with Bentek Energy expects coal-fired generation to be advantaged at least until the fall shoulder season.

Preliminary data published by the Energy Information Administration shows that the amounts of power generated by coal and natural gas in April were virtually equal. Was this a one-time event or an indicator of a future trend?

The D.C. Court of Appeals recently declined to examine the science behind the EPA’s Endangerment Finding that is the foundation beneath the its greenhouse gas rules. The next step is to challenge the EPA’s science.

Canada’s Nuclear Safety Commission (CNSC) on Tuesday approved restart activities at New Brunswick Power Nuclear’s (NBPN’s) Point Lepreau Generating Station, a 680-MW Candu 6 on the northern shore of the Bay of Fundy that has been offline for more than four years for a major refurbishment.

A Final Programmatic Environmental Impact Statement (PEIS) released by the Department of the Interior (DOI) and Department of Energy (DOE) on Tuesday identifies 17 Solar Energy Zones (SEZs) in six southwestern states—Arizona, California, Colorado, Nevada, New Mexico, and Utah—totaling about 285,000 acres of public lands, as priority areas for utility-scale solar development.

Princeton, N.J.-based NRG Energy and Houston, Texas-based GenOn on Monday signed a definitive agreement to combine the two companies in a $1.7 billion stock-for-stock tax-free transaction. The merger will create "the largest competitive generator" in the U.S. with a fleet of about 47 GW and assets in the East, Gulf Coast, and West, and a combined enterprise value of $18 billion, the companies said.

A coal dust explosion late on Tuesday at Polish utility Polska Grupa Energetyczna’s (PGE’s) 2.1-GW Turow power plant near Bogatynia in the southwestern part of Poland injured four workers and set off a blaze at three of the plant’s eight units. A team of more than 100 firefighters reportedly responded to the emergency at the facility that produces nearly 7% of power consumed in Poland.

An amended settlement reached with environmental groups will allow the Environmental Protection Agency (EPA) to delay by nearly a year issuance of rules that would govern cooling water intake structures at existing power plants and mandate compliance under Section 316(b) of the Clean Water Act.

The U.S. Court of Appeals for the D.C. Circuit last week handed the Environmental Protection Agency (EPA) two legal victories over challenges from states and industry, affirming the agency’s revisions to the National Ambient Air Quality Standard (NAAQS) for nitrogen oxides (NOx) and upholding its revised final sulfur dioxide (SO₂) standard.

Global solar trade tensions escalated on Friday as the Ministry of Commerce of the People’s Republic of China announced it would launch both anti-dumping and countervailing investigations on imports of solar-grade polysilicon from the U.S. and an anti-dumping probe on South Korean polysilicon imports. Germany on Friday, meanwhile, said it would support its solar industry in anti-dumping action against China.

The Environmental Protection Agency (EPA) intends to stay and reconsider new source emission standards contained in its February 2012-finalized Mercury and Air Toxics Standards (MATS), a letter from the agency’s assistant administrator, Gina McCarthy, shows.

Since 1977, more than 6,500-MW of nuclear uprates and been approved and many implemented in the U.S.—equivalent to the construction of six new nuclear power plants, the Energy Information Administration (EIA) said in an update on Wednesday.

A new report from the U.S. Chamber of Commerce claims that the Environmental Protection Agency (EPA) uses a regulatory tactic dubbed “sue and settle rulemaking” to force states to relinquish their authority and accept agency-promulgated plans to mitigate regional haze that are much costlier to implement.

Most steam generator tube wear or tube wall thinning at Southern California Edison’s (SCE’s) two-reactor San Onofre Generating Station (SONGS) was less than 20%—far below the 35% wall-thinning limit that would require the tubes to be plugged, data released last week by the Nuclear Regulatory Commission shows. Much of the wear was not "unusual," SCE said in a statement.

The $2 billion Potomac Appalachian Transmission Highline (PATH) may be canceled this fall, a project analysis update from PJM Interconnection suggests. The grid operator for 13 states suspended the 765-kV project last year pending further analysis.

Two Republican lawmakers are probing whether the Federal Aviation Administration (FAA) disregarded safety concerns and approved the Cape Wind project—the nation’s first offshore wind project—for political reasons.
