NEI's Energy Markets Report - October 1 - 5, 2007

Here's a summary of what went on in the energy markets last week:
Electricity peak prices increased between $3-13/MWh at all hubs. Generation outages and the lingering heat in the West drove prices at the Palo Verde and SP 15 hubs up by more than $10/MWh. Higher spot gas and hot temperatures also sent the Entergy, PJM West and ERCOT hubs up by more than $7/MWh. Peak prices at all the hubs last week were higher then the averages for the last four weeks and last 52 weeks (see pages 1 and 3).

Gas prices at the Henry Hub rose from $6.26/MMBtu to $6.54/MMBtu. Tropical storm fears and an increase in demand due to warmer than normal temperatures contributed to the increase in gas prices at the Henry Hub (see pages 1 and 3).

Nuclear plant capacity availability averaged 85 percent last week. Three reactors began refueling outages last week while two began maintenance (see pages 2 and 4).

Cushing OK WTI oil prices fell $0.55 to $81.70/barrel two weeks ago. Continued low surplus production capacity, weak petroleum inventories, and strong demand worldwide have all contributed to recent high crude oil prices (EIA’s STEO, see pages 1 and 3).

According to NOAA’s most recent projection of heating degree-days, winter in the lower- 48 States is forecasted to be 4 percent colder compared with last winter but 2 percent warmer than the 30-year average (1971 to 2000). Average winter-season (October 1 to March 31) prices and expenditures for all space-heating fuels are projected to be higher than winter 2006-2007. Cooling degree-days this summer were 12 percent higher than normal and slightly higher than last summer. For the entire year of 2007, total electricity consumption is expected to grow about 2.4 percent, primarily due to a surge in electricity consumption in the first quarter (EIA’s STEO, see pages 2 and 5).

Activists' Claims Distort Facts about Advanced Reactor Design

Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

How many nuclear plants does it take to meet the world's energy needs?

Several weeks ago Joshua Pearce at Clarion University in Pennsylvania released a study titled “ Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology .” In the study he stated... nuclear energy production would have to increase by 10.5% per year from 2010 to 2050 to both replace fossil-fuel-energy use and meet the future energy demands. This line, of course, made the headlines and has been picked up by several outlets and blogs . When looking into his calculations for this statement, he made one assumption error that overstated the above sentence by nearly a factor of three. Page 121, Section 4.1 of the study states: Richard Smalley pointed out that in 2004, the global economy consumed the equivalent of 220 million barrels of oil per day, which converted into electricity terms is the equivalent of 14.5 TeraWatts (TW), or 14,500,000 MegaWatts (MW) (2005). … With a nuclear plant having about 1000 MW (1 GW) of capacity, we would need 14,500...

What Happens During a Refueling Outage?

You may have noticed over the past few weeks that a number of nuclear plants are shut down for refueling outages or are resuming operations after just returning from one. This type of routine outage usually occurs in the spring or fall when electricity demand is low so that nuclear reactors can replace about one-third of the spent fuel rods with new fuel and conduct other routine maintenance and repairs at the plant. To get a better sense of how refueling works at a nuclear energy facility, I spoke with Marcus Nichol, NEI’s senior project manager for used fuel storage and transportation, and asked him to explain the basics. Why does a nuclear plant need to replace one-third of its fuel? Nichol: The main purpose of a refueling outage is to replace older fuel that is depleted—meaning it can no longer efficiently produce energy from nuclear fission reactions—with new fuel. This “used fuel” has typically been used in the reactor for four-and-a-half to six years before it is pe...
