In his January State of the Union speech, President Barack Obama called on Congress to pass legislation that would allow the U.S. to source 80% of its electricity from “clean energy” sources by 2035—including traditional renewable sources like wind and solar as well as nuclear and “clean coal.” That broadened definition of “clean energy” was designed to inspire bipartisan interest, as was widely reported. But, as was also widely pointed out, the speech followed a visit to Washington from Chinese government officials and a series of key agreements aimed at increasing “clean energy” cooperation between the two countries.

New methods of reliability, availability, and maintainability (RAM) evaluation help facilitate more-accurate plant output and revenue predictions, identify strengths and weaknesses of possible plant configurations, and determine potential improvements and enhancements for integrated gasification combined cycle plants.

Prior to the crash, the renewable energy industry—including wind, solar, geothermal, and other renewable energy sources—was on a roll. In 2007 and 2008, the U.S. wind power sector alone added over 13,500 MW of new projects, enough to power almost 4 million homes.

France in January announced its contribution to the wave of small and modular reactors (SMRs): a submarine-like nuclear plant that can be submerged in waters 60 meters (m) to 100 m deep and several kilometers offshore.

Steam turbines convert the thermal energy in motive steam to rotating mechanical energy, and the generator converts that energy into electrical power. One important requirement for safe and reliable operation is preventing water induction in the steam turbine and avoiding water hammer in the steam piping system. ASME standards present the design guidelines for removing moisture from steam lines; this article explains a practical design process.

Brazil’s environment agency, IBAMA, in January issued a partial installation license that allows for construction of the controversial Belo Monte dam complex, an 11,233-MW project estimated to cost some 19.6 billion reals (US$11.7 billion), to begin on the margins of the Amazon’s Xingu River. Saying the project is needed to meet soaring electricity demand when completed, as planned in 2015, the government gave license to dam-building consortium Norte Energia to begin clearing 238.1 hectares (588 acres) of forestland.

Europe installed 308 new offshore wind turbines in 2010—a 51% increase in installed offshore capacity over the previous year, the European Wind Energy Association (EWEA) said in new figures released this January. The 883 MW of new capacity—worth some €2.6 billion—were installed at nine wind farms in five countries, bringing the continent’s total offshore installed wind capacity to 2,964 MW.

A new article in Bioscience looks again at the connection between economic growth and energy demand, shedding little light on the subject and further demonstrating the limits of neo-Malthusianism. Of course there is a relationship between energy and economic growth, but what is it? No answers here; only a doomsday prediction.

At the beginning of 2011, German firm E.ON began operation of its new 417-MW Malzenice gas and steam turbine power station in Slovakia’s Trnava region, near the country’s capital, Bratislava (Figure 5). The facility, which is expected to generate more than 300 billion kWh annually, boasts an efficiency of 58%—which E.ON claims is among the “highest in Europe.”

The long-struggling uranium business, hoping that demand for nuclear fuel will increase, is slowly stretching its muscles and strengthening exploration and production efforts in the U.S. and elsewhere.

Lab-scale experiments have shown that seawater and calcium could effectively remove most of the carbon dioxide (CO₂) from a natural gas power plant’s flue gas stream. A large fraction of the captured gas could then be converted into dissolved calcium bicarbonate—which, pumped into the sea, could be beneficial to the ocean’s marine life, says a researcher representing both the Lawrence Livermore National Laboratory’s (LLNL’s) Carbon Management Program and the University of California, Santa Cruz.

The winter of 2010-2011 has been a cold one for financing renewable energy projects. That’s the weather report from a recent project financing meeting in New Orleans, a survey of developers and builders done by a large Minnesota construction company, and accounts from those in the financial trenches.

GDF SUEZ, RWE, and Iberdrola Pull out of Cernavoda Nuclear Expansion. French power company GDF SUEZ, Germany’s RWE, and Spain’s Iberdrola on Jan. 20 said they would no longer participate in a project to build Units 3 and 4 of the Cernavoda nuclear project in Romania. The companies cited “economic and market uncertainties surrounding the […]

Don’t get fixated on the Environmental Protection Agency’s moves against carbon dioxide. The real action is in the area of conventional air pollutants.

The popular television show Mythbusters uses pseudo-scientific means to examine and often expose as fiction familiar urban myths. After made-for-television lab tests, the myth is then classified as either a fabrication (“busted”), entirely possible (“confirmed”), or somewhere in between (“plausible”).

In the past, members of a utility’s engineering staff spent their career designing and building new power plants. Today, many utility engineers find that opportunity comes around only once in a career. To fill the experience gap, an “owner’s engineer” company can add to a utility’s team a cadre of highly qualified power engineers who focus on avoiding design errors and keeping the project on schedule.

While the cybersecurity threat escalates asymmetrically, federal agencies may be shortchanging cybersecurity while developing smart grid standards designed to protect the emerging smart grid from attack.

Thule (“Two Lee”) Air Base is a 254–square mile base located in a coastal valley in the northwestern corner of Greenland, within the Arctic Circle. The base, the U.S.’s northernmost military installation, is nestled between mountains and surrounded by icebergs and glaciers as far as the eye can see.

How does your company prepare and share fossil plant performance data? What data are important, and how much effort is required to collect and report the data? What are the most important statistics for reporting key fossil plant operations? The latest EUCG benchmarking survey reveals the favored fossil performance metrics at several of the largest utilities in eight key categories.

By Kennedy Maize Washington, D.C., February 24, 2011 – The most committed global warming alarmists are alarmed by the fact that – contrary to their claims that the science is settled – formidable scientists with worldwide reputations disagree. Credentialed experts such as Richard Lindzen and Roy Spencer do not buy what Jim Hansen, Michael Mann, […]

The U.S. House of Representatives on Saturday passed, with a 235-189 vote, a short-term government funding measure that cuts more than $61 billion from the remainder of the fiscal year (FY) 2011 budget—including a $3 billion slash to the Environmental Protection Agency’s (EPA’s) budget. The continuing resolution (CR) seeks to block the EPA from implementing or enforcing statutory or regulatory greenhouse gas (GHG) rules affecting stationary sources that became effective after January 1, 2011.

In response to a federal court order, the Environmental Protection Agency (EPA) today issued final Clean Air Act standards for large and small boilers and incinerators that burn solid waste and sewage sludge. The EPA said, however, that it would reconsider the rules because “certain issues of central relevance” arose after the period of public comment.

Following President Obama’s $97 million budget request last week to support research into small modular reactors (SMRs), Westinghouse introduced a 200-MW class integral pressurized water reactor modeled on the company’s third-generation AP1000 reactor. The company also said it was preparing to collaborate with the U.S. Department of Energy’s SMR demonstration program.

The past week brought important news from state legislatures regarding nuclear power plants. Minnesota voted to lift a 17-year ban on new nuclear plants; a bill that would allow utilities to recoup costs for early site permits advanced in Missouri; and the Indiana Senate is preparing, amid controversy, to vote on a key measure that could incentivize development and construction of new nuclear generation in that state.

Progress Energy’s CEO William Johnson, who last month agreed to a merger deal with Duke Energy, on Thursday told attendees at a conference that proposed nuclear power plants in Florida and North Carolina would not be operational until at least 2020.

Dominion Energy last week told ISO New England, the power grid operator for six New England states,  that it could shutter its 60-year-old 738-MW Salem Harbor coal- and oil-fired power plant in Massachusetts by June 2014 to avoid retrofitting the facility with expensive pollution controls required by federal environmental regulations.

By Kennedy Maize Washington, D.C., 22 February 2011 – NRG Energy’s South Texas two-unit nuclear project, which has been on life support for months, may soon win a loan guarantee from the U.S. Department of Energy, according to several industry sources. But the money for the loan guarantee may get tangled up in Congress’s current […]

No initial evidence had been found that the Texas power market had been manipulated when grid operator the Electric Reliability Council of Texas (ERCOT) on Feb. 2 ordered rolling blackouts, but investigations would continue, Texas regulators told legislators on Tuesday. The blackouts were necessary as some 82 power plants—out of 550 on the grid—went down for various reasons while freezing temperatures caused a record-breaking demand spike, ERCOT said.

Jacksonville, Fla., municipal utility JEA last week signed an agreement with Duke Energy that gives it the option to buy up to 20% of the power generated by Duke Energy’s planned 2,234-MW Lee Nuclear Station when it becomes operational in 2021.

The rupture of a 6-inch steam pipe at Unit 1 of the 1,884-MW coal-fired Homer City Generating Station in Indiana County, Pa., last week tripped the unit and sent six workers to area hospitals with burns.
