Rwanda’s Lake Kivu has a nickname: “Killer Lake.” The shimmering 1,040–square mile body of freshwater on the western branch of the Great East African Rift that straddles the Democratic Republic of Congo and Rwanda has had a bloody history. Not only was it the site of atrocity during the 1994 Rwandan genocide, but scientists say that it is also one of three known “exploding lakes.”

Ascertaining the alignment of all machines in a multiple machine train has always been a cumbersome and time-consuming process. The new ROTALIGN ULTRA MultiCoupling feature allows the alignment of up to seven machines in a train to be measured simultaneously, with a single quarter rotation (or less) of the shafts. This saves time and resources […]

Three nuclear reactors under construction in the Eastern Hemisphere reached major milestones over the past few months. South Korea’s Korea Hydro and Nuclear Power Co. connected its 960-MW Shin-Wolsong 1 reactor near Nae-ri to the grid on Jan. 27 and, a day later, its sister plant, the 960-MW Shin Kori 2 (Figure 5) in the southwest city of Gori. Both units are expected to become commercially operational this summer. And last December, Russia began commercial operation of its 950-MW Kalinin 4 plant, a V-320 model VVER 1000.

Ten years ago, I could not have written this column. The natural gas industry was different—limited domestic supply resulted in unstable prices. However, recent advancements in drilling technology have enabled the industry to discover, access, and produce abundant sources of natural gas in America. Because the industry has changed, the country’s energy future is now […]

The UK opened two massive offshore wind farms this February on the Irish Sea off the UK’s Cumbrian coast. DONG Energy, SSE, OPW, and a consortium of Dutch pension fund service provider PGGM and Ampere Equity Fund began commercially operating the 367-MW Walney wind farm, estimated to cost $1.58 billion, and Danish wind firm Vattenfall inaugurated the Ormonde Offshore Wind Farm.

India has been besieged by a coal shortage of unprecedented severity that has forced privately owned and money-strapped state-owned coal-fired power plants alike to rely on expensive imports from Indonesia and South Africa to replenish woefully inadequate stocks.

As a Valentine’s Day present to federal regulators, San Francisco City Attorney Dennis Herrera took the unusual step of suing the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA). The complaint alleges that the PHMSA has “abjectly failed to oversee the [California Public Utilities Commission’s (CPUC’s)] pipeline safety program or to ensure that federal pipeline safety standards are enforced.” The complaint chastises the PHMSA for “shirking that duty for over a decade, if not longer.”

CSP Giants Form Alliance. Concentrating solar power companies Abengoa, BrightSource Energy, and Torresol Energy in early March formed the Concentrating Solar Power Alliance, an organization dedicated to educating U.S. regulators, utilities, and grid operators about the unique benefits of concentrating solar power (CSP) and of thermal energy storage. The U.S. has more than 500 MW […]

An energy policy should be the result of inclusive debate and a consensus approach to the means to leverage all of a country’s energy assets, including innovation and technology, to the advantage of its citizens. Current U.S. energy policy fails on all counts.

Confined space work is often considered to be one of the most dangerous types of work performed in power generation settings. Confined spaces may contain hazardous atmospheres, they can trap entrants, and they generally can increase the hazards associated with otherwise common tasks. When the risks are not recognized, workers all too often regard incidents as surprises, but the hazards of working in confined space can be predicted, monitored, and mitigated. These “accidents” are caused by unsafe conditions, unsafe acts, or both; all accidents are preventable.

Common fuel-handling problems in the power industry often result in production downtime, costing the owner perhaps up to $200,000 per hour. There are many areas within a coal-fired power plant where mishaps can cause stoppage of material flow. Here we discuss how to select the best switch technology to reduce the possibility of coal flow stoppages.

WTE technologies offer cost-effective, near-term solutions for producing baseload electric power, meeting renewable energy targets, and reducing greenhouse gas emissions in the U.S. and other countries. They also present opportunities for improving resource management practices, increasing energy security, enhancing environmental quality, and supporting climate policy goals around the world.

The Environmental Protection Agency (EPA) on Tuesday proposed its first-ever carbon pollution standard for new power plants, limiting carbon dioxide (CO₂) emissions from new fossil fuel-fired power plants to 1,000 pounds/MWh. The standard is achievable for new natural gas combined cycle units without add-on controls, but it would force new coal or petroleum coke units to install carbon capture and storage (CCS) technology, which is currently commercially unavailable, the agency acknowledged.

Southern California Edison (SCE), operator of the San Onofre Nuclear Generating Station near San Clemente, Calif., must understand and address unusual wear on steam generator tubes before it can be allowed to restart the beleaguered two-reactor nuclear plant, the Nuclear Regulatory Commission (NRC) said on Tuesday. California officials are meanwhile preparing contingency plans to prevent power outages this summer that could result from the plant’s indefinite shutdown.

The Nuclear Regulatory Commission (NRC) will decide on Friday whether to award a combined construction and operation license (COL) to SCANA Corp.’s proposed project for two 1,117-MW reactors at the site of the V.C. Summer Nuclear Station near Jenkinsville, S.C. If the SCANA Corp. project receives the NRC’s approval, it will be the second project in nearly 30 years to receive such approval.

Official notifications to regional reliability organizations PJM Interconnection and Southwest Power Pool (SPP) made last week by American Electric Power (AEP) show that the company will retire about 4,600 MW of coal-fired capacity to comply with a series of Environmental Protection Agency (EPA) rules. The plan differs markedly from the 6,000 MW of anticipated retirements AEP announced in June 2011.

Bulgaria on Wednesday definitively abandoned plans to build the Belene nuclear plant based on Russian technology, saying it would instead build a gas-fired power plant on the Danube River site. Bulgarian Prime Minister Boyko Borisov cited soaring costs as well as a failure to find Western partners for the projects after German company RWE withdrew from the project in 2009.

Two natural gas–fired projects received key approvals from state regulators this week. The Florida Public Service Commission on Tuesday approved Florida Power & Light’s (FPL’s) proposed 1,277-MW gas unit for Broward County, Fla., and Louisiana’s Public Service Commission approved Entergy’s 550-MW gas project for Jefferson County, La.

Pushing for an “all-out, all-of-the-above” energy strategy, the Obama administration last week announced new funding to advance the development of small modular reactors (SMRs) in the U.S.

By Kennedy Maize Washington, D.C., 28 March 2012 — Just how significant is the Obama administration’s new regulation on carbon dioxide emissions from new coal-fired power plants, announced yesterday? From here, it looks like a fair amount of ado about not very much. In today’s cynical political environment, it’s hard not to see the Environmental […]

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 Part I of a three-part report, we introduce the A-USC boiler. Future reports will discuss the metallurgical and boiler design challenges.

What killed global warming as the president’s number one priority?

Freedom, opportunity, prosperity, and a civil society have made America exceptional. But without energy—secure and affordable energy—many of our great accomplishments would not have been possible.

FirstEnergy Corp., AEP, and GenOn have all announced coal-fired plant closures, totaling over 13 GW, caused by the recently finalized Mercury and Air Toxics Standards.

A proposed rule issued in late February by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.

It has been said that a picture is worth a thousand words. However, photos of the conflagrations that have resulted from ignition of minor lube oil leaks on a typical steam turbine room floor will leave you speechless. Full-scale physical simulations of oil fires by the insurance company FM Global leave no doubt that power plant fire prevention and mitigation is a judicious blend of art and science.

This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal.

Moving into the election season, President Obama has again pointed to the number of green jobs supposedly created by his administration in a recent campaign advertisement, although the claims are not supported by available data. Now, other government authorities are using the same poor data as an excuse to increase spending.

In the past week, Ontario’s Bruce A restarted after 17-year hiatus, with hiccups; Indian state approval restarted work to complete Kudankulam; Vermont Yankee turned 40; and Entergy won a new legal round to keep the contested Vermont reactor operating.
