When sootblower operation frequency is too high, a plant risks losing power generation from tube leaks; but when sootblower frequency is too low, there is a risk of boiler pluggage. Intelligent sootblowing finds the right balance between tube erosion and plant economic operation.

Tokyo Electric Power Co.’s (TEPCO’s) Fukushima Daiichi 1 reactor—a unit that suffered a core melt and hydrogen gas explosion after the March 11 earthquake in Japan and subsequent tsunami devastated the six-reactor facility—was fully encased in an “airtight” cover in October.

The newest member of the 60% thermal efficiency combined cycle club is GE Energy’s FlexEfficiency 50. In an era when flexible grid operation is growing in importance, this 50 Hz, single-shaft combined cycle also holds its design point efficiency down to 87% load and features turndown to 40% of rated load.

Since a 2008 University of Texas-Austin study showed that converting farm animal droppings into renewable power could generate enough power to meet up to 3% of North America’s consumption, interest in cow power has been piling up.

Geothermal power and conventional fossil fuel–powered technologies have similar power production cycles, and both generation types can be dispatched. Geothermal power’s primary advantage is its renewable fuel. Its primary disadvantage is that its fuel requires large investments over many years to characterize uncertain sources. Enhanced recovery techniques that use fracking may be the future of this renewable resource.

A structure or mechanical system that requires fasteners also demands tools to maintain it properly. In power sectors such as wind, fossil fuel, and nuclear, some work areas may be several hundred feet in the air. While working at those extreme heights, or even just 10 feet off the ground, it’s simply unacceptable to drop anything. That’s why the concept of “tools at height” is being embraced as a way to improve safety and efficiency on the worksite.

Hendrix Wire & Cable, a provider of overhead and underground power distribution products, introduced its Spacer Cable Systems, a “green” solution for overhead distribution circuits. Because Spacer Cable is more compact and can withstand temporary contact with branches without causing outages, Hendrix Spacer Cable Systems can help reduce the amount of vegetation that must be […]

Inlet fogging systems for combustion turbines achieve their effect at the molecular level: The cooling effect occurs by converting thousands of gallons of water into single evaporated molecules suspended in the air. The right fog pattern comes down to a matter of selecting the best nozzle design and proper placement in the inlet air stream.

Correct welding procedures are extremely important elements of the work done by the PSEG Central Maintenance Shop (serving Public Service Electric and Gas Co., PSEG, a New Jersey utility). We have, for example, a Critical Weld Inspection Program for high-temperature pressure piping whose goal is to identify cracks in high-temperature piping welds.

Harrington Hoists launched the RHN Series, a new line of electric wire rope hoists, offered in two configurations: the deck/base-mounted hoist in 2–20 metric tons and ultra-low-headroom trolley hoist in 2–15 metric tons. Both versions are dual speed. The deck/base-mounted hoist features a compact, modular design that is perfect for stationary applications or combined with […]

The Federal Energy Regulatory Commission (FERC) earlier this month issued a proposal to revise the methodology for calculating rental rates for the use of government lands by hydropower projects. Under the proposal, FERC-regulated hydropower licensees must compensate the federal government for the use of federal lands, significantly increasing annual charges for many hydropower projects occupying federal lands.

Google, the Internet search giant that has invested millions in solar power technology, last week quietly abandoned a four-year-old project to make renewable power cheaper than coal-fired power. The company, which cited the recent dramatic decline of photovoltaic panel prices and design limitations, said other institutions were “better positioned” to take research to the “next level.”

SolarCity Corp., a solar power company that lost a $344 million conditional loan guarantee from the Department of Energy (DOE) in the political rumpus following the Solyndra’s failure, today announced it would move ahead with an ambitious five-year plan to build more than $1 billion in solar power projects for privatized U.S. military housing communities across the country.

The cumulative impact of rules proposed and finalized by the Environmental Protection Agency (EPA) could, over the next six years, stress the nation’s power grid "in ways never before experienced," the North American Electric Reliability Corporation (NERC) warns in a new report.

The FutureGen Alliance, a nonprofit coalition of coal producers, coal users, and coal equipment suppliers, on Monday said it was negotiating an option to buy portions of the Meredosia Energy Center in Illinois from Ameren Corp. to continue development of the FutureGen 2.0 carbon capture and storage project, an initiative begun in 2003.

Illinois’ Senate on Tuesday revived Tenaska’s plan to build its $3.5 billion Taylorville Energy Center (TEC), a 602-MW integrated gasification combined cycle (IGCC) power plant designed to capture more than 50% of its carbon emissions.

By Kennedy Maize Washington, D.C., November 17, 2011 — Let’s stipulate: Texas Gov. Rick Perry is a doofus. I’ve elsewhere characterized him as “a stuffed shirt, in an empty suit, talkin’ through his hat.” I was being kind. In his recent debate “Oops!” moment, Perry was able to name only two of the three federal […]

The U.S. Environmental Protection Agency (EPA) on Thursday issued the first greenhouse gas (GHG) permit in Texas. The move comes nearly a year after Texas refused to implement federal GHG regulations that require air permits for high-emission projects and the EPA seized the state’s authority to grant permits.

Power costs from onshore wind turbines are expected to plunge 12% over the next five years due to the availability of lower-cost equipment and gains in output efficiency—and, in areas offering fair wind conditions, this could make wind power “fully competitive” with power produced from combined cycle gas turbines by 2016, new research from Bloomberg New Energy Finance shows.

Dominion Virginia Power on Friday began the restart of North Anna Power Station after garnering the Nuclear Regulatory Commission’s (NRC’s) permission and more than two months of inspections, testing and engineering, and seismic analysis to investigate effects of the Aug. 23 5.8-magnitude quake whose epicenter was only about 11 miles away from the company’s twin-reactor station in Mineral, Va.

A survey of 50 energy experts released on Tuesday by economists at The Brattle Group reveals that energy efficiency is likely to cause a drop of 5% to 15% in U.S. electricity consumption by the year 2020, relative to forecast trends. Electric peak demand is likely to drop by 7.5% to 15% and natural gas consumption is expected to drop by 5% to 10% compared to forecast trends.

A plan to build a controversial $4.7 billion coal-fired power plant in Scotland’s Ayrshire County that would have been fitted with experimental carbon capture and storage (CCS) technology was last week thrown out by the North Ayrshire Council, and citizens lodged more than 20,000 objections with the legislative body.

The U.S. Senate on Thursday blocked two key bills proposed by Republicans that would have thwarted the Environmental Protection Agency (EPA) from promulgating rules they say are unrealistic and would harm the economy. One measure was Sen. Rand Paul’s (R-Ky.) resolution to disapprove the EPA’s Cross-State Air Pollution Rule (CSAPR), and the other was Sen. John McCain’s (R-Ariz.) bill that would have required agencies to get congressional approval for federal rules that cost more than $100 million.

A Minnesota administrative judge on Thursday backed a $489 million plan to retrofit the 36-year-old coal-fired Big Stone power plant in South Dakota with an air quality control system (AQCS) rather than scrap the plant.

The California Public Utilities Commission’s (CPUC’s) approval on Thursday of Abengoa Solar’s 250-MW Mojave Solar concentrating solar power (CSP) parabolic trough facility in San Bernardino County—the second “overpriced renewable contract” approved by the CPUC in recent weeks—was disappointing, the regulatory commission’s Division of Ratepayer Advocates (DRA) said in a statement.

If the Senate votes on a measure this week to overturn the Cross-State Air Pollution Rule (CSAPR) using the Congressional Review Act, as has been spearheaded by Sen. Rand Paul (R-Ky.), President Obama would veto the resolution.

The Obama administration on Tuesday posted a notice on the White House Office of Management and Budget (OMB) website that indicates the Environmental Protection Agency (EPA) has filed a copy of proposed rules to limit greenhouse gas (GHG) emissions from new, modified, and existing power plants.
