A number of automotive manufacturers, electric utilities, electric power associations, and research groups are working to develop and evaluate technical approaches to integrating plug-in electric vehicles (PEVs) into the U.S. electrical grid system. This is a key requirement of facilitating widespread, near-term adoption of PEVs by the American public.

Why should utilities consider converting existing coal-fired plants to burn gas? We explore the rationale for fuel switching, some of the options available for the conversion of coal-fired units, technical considerations related to conversion, and some of the financial considerations that will impact the final decision.

Just as GE Energy, Siemens, and Mitsubishi Heavy Industries (MHI) in May announced gas combustion technology developments—each seeking to push the 60% barrier with new gas turbine designs—Alstom has quietly been upgrading its KA26 combined cycle power plant. (See the July 2011 “Global Monitor” for more information on the GE, Siemens, and MHI turbines.) The firm says that the next generation of the 500-MW power plant, based on the advanced class GT26 gas turbine, features “achievable” efficiencies of over 61%, increased flexibility, and more than 350 MW, which can be delivered in less than 15 minutes to help integrate renewable energy sources (Figure 3).

Steve Elonka began chronicling the exploits of Marmaduke Surfaceblow—a six-foot-four marine engineer with a steel brush mustache and a foghorn voice—in POWER in 1948, when Marmy raised the wooden mast of the SS Asia Sun with the help of two cobras and a case of Sandpaper Gin. Marmy’s simple solutions to seemingly intractable plant problems remain timeless. This Classic Marmaduke story, published more than 50 years ago, reminds us that an overhaul or startup may not go as planned, but it can still have a happy ending.

Proponents of carbon dioxide emission reductions from power plants are lamenting the decision by American Electric Power to cancel the carbon capture and sequestration plant at its Mountaineer facility in West Virginia. It’s not politics, it’s just business.

Companies continue to increase the size of carbon capture and sequestration test projects. Mitsubishi Heavy Industries (MHI) has launched operation of what it calls the world’s largest demonstration of carbon capture on a pulverized coal plant.

BIRNS Inc., designer and manufacturer of lights for the nuclear power industry, introduced enhancements to the popular BIRNS Kelvin—a 16,000-lumen tungsten halogen light that features a 120 volt/1,000 W lamp with instant on/off and hot-restrike capability. Designed for underwater use in areas with high levels of radiation and nuclear contamination, the new model 5813 now […]

Weeks after Brazil’s environmental agency, IBAMA, granted final approval for construction of the mammoth 11.2-GW Belo Monte Dam in the Amazon region to proceed, an appeals court in Chile suspended plans for the 2.75-GW multi-dam HidroAysen project in the Patagonia region, and Peru’s government terminated a concession for the 1.5-GW Inambari in the Peruvian Amazon area after month-long mass protests (Figure 5).

New Pig Corp. launched the “PIG UV-Resistant Spill Kit in a 95-Gallon Container” as an easy oil-spill clean-up solution to large outdoor spills. Suitable for outdoor use and storage, the PIG UV-Resistant Spill Kit is nontransparent, providing superior protection of absorbent contents from UV degradation during long-term storage outdoors. The container includes enough PIG oil-absorbent […]

Statkraft began operating its 4-kW prototype osmotic power plant at Tofte, just outside Oslo, Norway, in 2009. Now the firm reports that it is close to developing a large-scale plant. In June, Statkraft and Japanese materials manufacturer Nitto Denko/Hydranautics signed an agreement for the development and supply of membranes specifically designed for use in large-scale osmotic power plants.

Danray Products introduced a line of heavy-duty lathe carriage (saddle) shields that are designed for manual lathes or similar machines. The shield attaches directly to the backside of the carriage, so it moves with the carriage as the work piece is being machined. This provides a barrier between individuals and the point-of-operation hazard. The shield […]

Two years after it laid the foundation stone, Germany’s E.ON on June 27 opened Hungary’s most efficient combined cycle gas turbine (CCGT) power plant (Figure 7). The €400 million ($573 million) plant in Gönyü has a capacity of 433 MW and an efficiency of over 59%, E.ON claims. Siemens supplied the main components: an SGT5-4000F gas turbine, an SST5-5000 steam turbine, an SGEN 5-3000W generator, and the entire electrical and instrument and control equipment. The natural gas–fired power plant is of single-shaft design with the main components arranged in a single driveline.

With the U.S. economy still struggling, few things are as important as having an abundant, reliable supply of energy to help drive our recovery. Many American families are hurting and our businesses are being challenged to create new jobs. That’s why federal, state, and local public policies must balance the need for broader economic prosperity, […]

By Kennedy Maize Washington, D.C., July 30, 2011 — If you want “outside the box” thinking, don’t ask it from those who built the box. That’s the thought that came to mind when I read this week’s draft report from the group of Washington has-beens and hangers-on the Obama administration asked last year to formulate […]

The U.S. Federal Energy Regulatory Commission (FERC) finalized an order last Thursday that it says reforms its transmission planning and cost allocation requirements “to benefit consumers by enhancing the grid’s ability to support wholesale power markets and ensuring transmission services are provided at just and reasonable rates.”

South Carolina state-owned utility Santee Cooper last week said it had separately signed letters of intent with Duke Energy Carolinas and Florida Municipal Power Agency (FMPA) to negotiate partnerships in the two new nuclear reactors at the V.C. Summer Nuclear Generating Station that Santee Cooper is planning with South Carolina Electric & Gas (SCE&G).

The Environmental Protection Agency (EPA) said on Tuesday it would not issue a reconsideration of the Bush administration’s ozone standard by the July 29 deadline, but it will finalize the standard “shortly.”

Entergy Corp. on Monday said it would move forward with fabrication of fuel and refueling of the Vermont Yankee nuclear power plant this October—even though the New Orleans–based company will then be embroiled in a federal court trial against the state of Vermont. The state is determined to shut down the nuclear plant as soon as a Legislature-approved permit expires in March 2012.

Southwestern Electric Power Co. (SWEPCO) on Monday said it has settled a series of lawsuits and other actions brought forth by an assortment of groups opposing construction of the 600-MW John W. Turk., Jr. power plant—the nation’s first ultrasupercritical pulverized coal power plant.

Fourteen of the European Union’s (EU’s) 27 member states that operate nuclear power plants must draw up national programs for the management of spent nuclear fuel—including concrete timetables and cost assessments—and submit them to the European Commission by 2015, at the latest, under a new EU directive adopted last week.

The U.S. Department of Energy’s National Energy Technology Laboratory (NETL) and Montana State University (MSU) said on Tuesday they would begin work on a $67 million, eight-year project that will involve permitting, injecting, and monitoring one million tons of carbon dioxide (CO2) to be stored in deep porous rock formations in northern Montana.

Backlash against the U.S. Environmental Protection Agency’s (EPA’s) newly finalized Cross-State Air Pollution Rule (CSAPR) mounted in the past week as Texas state agencies, utilities, and regional grid operator the Electric Reliability Council of Texas separately warned that the state could face a generation shortage if the federal pollution rules were implemented as written.

A federal judge on Monday threw out Entergy Corp.’s bid for a preliminary injunction to stop the state of Vermont from shutting down the Vermont Yankee nuclear plant in March 2012, when its original 40-year license expires. The ruling will force the company to decide whether it will buy $65 million of nuclear fuel to keep the plant running until a trial begins this September, or to shut down the plant.

Duke Energy’s 862-MW W.C. Beckjord Station southwest of Cincinnati, Ohio, is the latest coal-fired power plant that will be shuttered as a result of the U.S. Environmental Protection Agency’s (EPA’s) recently proposed Utility Maximum Achievable Control Technology (MACT) rule.

Portland General Electric (PGE) and environmental groups on Tuesday reached a consent decree that will resolve alleged Clean Air Act violations at the 585-MW Boardman power plant—Oregon’s only coal-fired plant—by capping sulfur dioxide emissions and phasing out the use of coal by 2020.

The U.S. Environmental Protection Agency (EPA) last week proposed secondary air quality standards for nitrogen oxides (NOx) and sulfur oxides (SOx), building on rules—like the recently finalized Cross State Air Pollution Rule—to reduce NOx and SOx emissions.

Rentech Inc.’s proposed St. Joe Renewable Energy Center—one of the world’s first biomass integrated gasification combined cycle (BIGCC) projects—last week received a final air permit from the Florida Department of Environmental Protection and will now begin construction of the planned project.

The U.S. Department of the Interior (DOI) on Thursday announced approval of four new renewable projects on public lands, including two utility-scale solar developments in California, a wind energy project in Oregon, and a transmission line in Southern California.

On Tuesday, the Federal Energy Regulatory Commission (FERC) issued an order in which it said it found insufficient consensus on smart grid interoperability standards to require it to institute a rulemaking procedure. It urged industry participants to continue working with the National Institute of Standards and Technology (NIST) to develop such standards.

Just a month after American Electric Power (AEP) announced it would shut down 6 GW of its coal-fired capacity by 2014 because of new federal emission rules, the Ohio-based utility on Thursday terminated a cooperative agreement with the Department of Energy (DOE) and brought a $668 million project to commercialize carbon capture and storage (CCS) to a screeching halt, citing an uncertain U.S. climate policy and the weak economy.
