The power-hungry ERCOT region is getting an upgrade, as Siemens and Bechtel are building two advanced combined cycle plants in central Texas.

When the Albany area needed a new power plant, pulling water from the Hudson River would have been the easy choice. But the plant owners chose to get creative, drawing on a convenient but unconventional source for their cooling water.

The bill for German Chancellor Angela Merkel’s coalition government’s knee-jerk decision to close all 17 of its nuclear plants by 2022 is coming due. Merkel’s energy plan is to radically expand the use of renewable energy to 35% of total power consumption by 2020 and to 80% by 2050. Currently, renewables represent 20% of the country’s energy mix.

With license extensions for its three units in hand, Duke Energy’s Oconee Nuclear Station began a digital controls upgrade program in 2006, and in January 2010, AREVA became the first supplier to receive Nuclear Regulatory Commission approval for a safety-related digital instrumentation and controls system.

Germany-based solar mirror maker Flabeg has developed an anti-soiling coating for solar mirrors used in solar thermal power plant applications, duraGLARE, which can repel dust and sand from the surface of mirrors. Dirt on mirrors can be reduced up to 50% compared with panels that are not coated, the company claims. As well as an […]

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the sixth and seventh chapters, “The Bomber to Nowhere” and “The Road to Jackass Flats,” which begin the “Up in the Air: Flights of Radioactive Fancy” section.

No other country has been as frequently cited as an example of exploiting the virtues of a nuclear-heavy energy policy as France. Deriving more than 75% of its electricity from 58 operational nuclear reactors with a total capacity of about 63 GW, France has one of the lowest costs of generation and is the world’s largest net exporter of power, earning €3 billion ($3.9 billion) a year from sales of surplus power to buyers beyond its borders. But that is all about to change.

On August 23, 2011, at 1:51 p.m., a magnitude 5.8 earthquake knocked both units at Dominion’s North Anna Power Station off-line—the first time such an event has occurred in the U.S. After 80 days of extensive evaluation and inspection by plant staff and representatives from the U.S. Nuclear Regulatory Commission, both units were back online. What occurred during those days is a remarkable story.

Measurement technology specialist Testo announced the new Testo 875i thermal imager, a professional quality and versatile thermal imager with very high thermal sensitivity, outstanding image quality, and simplified ease of use. With the device’s high thermal sensitivity of less than 50 mK, and the outstanding image quality of 160 x 120 pixels (which can be […]

The back-to-back collapse at the end of July of India’s Northern, Eastern, and Northeastern grids that slashed power to more than 60% of India’s population of 1.24 billion has impelled the country into a spending frenzy to upgrade its rickety power network, which, a government inquiry revealed, was one cause of the unprecedented blackouts.

Data detailing plans for new nuclear reactors worldwide show few effects of the March 2011 Fukushima accident. China and Russia in particular continue to be hot spots for nuclear development, but cost overruns, construction glitches, and ongoing safety reviews are slowing construction projects elsewhere.

ESAB introduced a new, improved line of combination cutting torches as part of the new Purox Elite Series of gas apparatus products. The Purox Elite Series Combination Torch includes the WH-4200 welding handle and the CA-4200 cutting attachment. The torch welds material up to 1 inch thick and cuts up to 8 inches in thickness. […]

Germany’s E.ON this August began construction of a new pilot plant in Falkenhagen in northeast Germany that will convert excess wind energy into synthetic natural gas that can then be fed into the regional gas grid, where it can be used to produce heat and power.

The California Public Utilities Commission (CPUC) has opened a formal investigation into the extended outages of Units 2 and 3 at the San Onofre Nuclear Generating Station (SONGS). The investigation will determine whether to remove all costs related to SONGS from the rates of Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E) going forward, and whether to refund SONGS-related costs already collected in rates back to Jan. 1, 2012.

A massive blackout spanning 11 states in northeastern Brazil plunged nearly 53 million residents into the dark early on Friday morning. The event, caused by a "total collapse" of the northeastern grid, has raised concerns about electric reliability in South America’s largest economy, which is gearing up to host the World Cup soccer tournament in 2014 and the 2016 Olympic Games.

The Electric Power Research Institute and several partners—including the Southern Research Institute, Southern Co. subsidiary Georgia Power, and Southern Research—are testing a new technology that could reduce the amount of water needed for power plant cooling.

On Tuesday morning, half a day after Hurricane Sandy made landfall in New Jersey, the enormous storm, now being called a superstorm or a post-tropical cyclone, was still causing destruction far inland while as many as 6 million electric customers from Maine to North Carolina and west to Pennsylvania and West Virginia were without power.

Four coal and two oil generating units at two of the oldest power plants owned by Santee Cooper are to be retired. South Carolina’s state-owned utility said last week that the decision was reached by its board of directors after considering generation resource needs and the cost of complying with new environmental regulations.

Global Companies Take on Nigeria’s Newly Privatized Plants. Nigeria’s $1 billion liquidation of five government-owned thermal and hydropower generation companies—part of a wider privatization effort that includes transmission and distribution assets to encourage investment in the power shortage–stricken country’s electricity sector—has attracted a number of global companies and investors. Eight firms bid a total of […]

Natural gas–fired generation gave up some ground to coal during the third quarter, and coal producers are optimistic that higher natural gas prices will benefit coal, especially coal sourced from the Powder River Basin in Wyoming. Even so, at least one Midwest utility expects natural gas to power what could be as much as 1,500 MW of new generating capacity it may add over the next several years.

In a bid to encourage construction of new power plants in power-strapped Texas, the state’s Public Utility Commission (PUC) last week voted to double the wholesale price cap for electricity prices by the summer of 2015.

When a nuclear power plant experiences ground motion due to an earthquake, an evaluation may be needed before allowing the plant to continue operating or to resume operating if it has been shut down, as was the case after the seismic event that shut down both units at Dominion’s North Anna Power Station on August 23, 2011.

Hitachi announced on Tuesday that it had acquired Horizon Nuclear Power in a deal expected to be completed by the end of November. In another example of the global nature of the nuclear business, the Japanese firm purchased Horizon, which was developed by the UK to build new nuclear plants, from German companies RWE and E.ON.

The first quarterly update from the Tennessee Valley Authority (TVA) reporting construction progress of the Watts Bar Unit 2 nuclear reactor suggests that the project is on track for completion between September and December of 2015 and is within its budgeted cost range of $4 billion to $4.5 billion.

All turbo machinery is subject to degradation that, over time, will affect the system’s efficiency and operational performance. Precise monitoring of turbo machinery performance with continuous torque-monitoring systems can be used to identify gradual efficiency loss. That, in turn, allows a more focused maintenance scope to be developed that can return the system to its optimum operation and efficiency.

China regards nuclear energy as a critical part of its strategic goal of achieving sustainable economic development while reducing environmental pollution. An analysis by North China Electric Power University predicts that the pace of nuclear power development may slow for a short time as a result of the Fukushima accident, but nuclear power is still a top development priority.

A “who’s doing what” addendum to "THE BIG PICTURE: Advanced Fission" in our November 2012 issue.

A number of factors promote effective and responsible completion of EHS audit action plans, with the most important being the proper alignment of responsibility and authority for developing and implementing the audit action plan.

The Clean Water Act Section 316(b) rule changes regarding cooling water intake structures that are expected next year could affect up to 428 power plants, representing 1,156 individual units, according to the Electric Power Research Institute. Depending on plant size and the complexity of the retrofit project, retrofit capital costs could range from very low to over $500 million for large nuclear plants. The power industry total cost is projected to be over $100 billion.

On June 15, in response to a court order, the U.S. Environmental Protection Agency (EPA) proposed new lower limits on particulate matter (PM) emissions that are scheduled for release in mid-December, although that deadline may be missed. Even with implementation delays, now is a good time to start paying closer attention to the requirements of the proposed standard.
