The “shale gale” blows on unabated, as new calculations for U.S. gas reserves point toward even greater resources than previously thought.

Last year’s stampede toward gas in the power sector is moderating for 2013, as higher gas prices cut into the economic incentives supporting coal-to-gas switching.

Energy storage has been the achilles heel of the renewable boom, but new technology may offer a way to join gas and renewables even more closely—by using excess renewable generation to manufacture synthetic natural gas from carbon dioxide.

The bad luck for Southern California Edison’s (SCE’s) crippled San Onofre Nuclear Generating Station (SONGS) continued this week. The local ABC affiliate in San Diego reported on April 30 that it had been given a photo of a makeshift repair to the water box in Unit 3  by a plant employee.

Dominion subsidiary Virginia Power may choose to use a GE-Hitachi Economic Simplified Boiling Water Reactor (ESBWR) instead of a Mitsubishi Nuclear Energy Services (MNES) Advanced Pressurized Water Reactor (APWR) for a third nuclear unit proposed at its North Anna site in Virginia, the company said in a Securities and Exchange Commission (SEC) filing on Friday.

ComEd’s smart grid program finally has some good news to share. In a progress report to the Illinois Commerce Commission (ICC) this week, the utility said that 479 distribution automation (DA) devices installed in the first year of the program resulted in 82,000 fewer customer power interruptions in 2012.

Natural gas pipeline maintenance this summer could affect natural gas supplies to some power plants in the six-state New England region, but forecasts suggest that summer electricity supplies will adequately meet consumer demand under normal weather conditions, ISO New England (ISO-NE) said on Monday.

An informational notice recently issued by the Nuclear Regulatory Commission (NRC) cautions nuclear power plant operators to look out for moisture degradation of structures and components used to store spent nuclear fuel in dry casks.

Federal Energy Regulatory Commission (FERC) hearings on issues related to natural gas and its use for electric power generation continue this month. The next hearing is set for May 16, two days after Commissioner Philip D. Moeller addresses the natural gas/electric power generation nexus in keynote remarks delivered to the 15th annual ELECTRIC POWER Conference in Chicago. POWER is a media affiliate of the conference.

Navajo Nation President Ben Shelly signed a land lease extension on April 30 for the 2,250-MW Navajo Generating Station, but not before adding several amendments to the agreement. The early lease renewal with the Navajo Nation must be in place before plant owners could consider making future investment in expensive new air quality control equipment.

Edison International said that without a restart of Unit 2 at its San Onofre Nuclear Generating Station (SONGS), it could decide by the end of the year to retire both units at the California nuclear plant. The units with a combined generating capacity of 2,350 MW have been offline since early 2012, the result of unexpected erosion and tube leaks in their steam generators. Costs tied to the shutdown now total around $553 million, including $109 million spent on inspections and repairs and $444 million for replacement power.

Drought is a serious vulnerability for the power sector, witnesses testified at a full committee hearing held last week in the Senate to assess the impacts of drought on the power and water sectors. Members of the panel invited by the Senate Committee on Energy and Natural Resources offered a number of possible solutions for federal agencies and power companies that could mitigate adverse effects from drought.

A bipartisan group of senators have introduced legislation that would effectively shift responsibility for the disposition of spent fuel from U.S. nuclear power plants from the Department of Energy (DOE) to a new agency created solely to deal with nuclear waste issues.

The Nuclear Regulatory Commission (NRC) ruled that a partnership between NRG Energy and Japan’s Toshiba Corp. to build two new ABWR reactors at the South Texas Project (STP) outside Bay City, Texas, through the holding company Nuclear Innovation North America (NINA) continues to be dominated by foreign control. Until NINA can come up with a different corporate ownership structure, the NRC said it could not approve the project’s combined construction and operation license (COL).

In the U.S., where construction of new nuclear reactors has stalled for three decades, two separate nuclear projects completed placement of basemat structural concrete for new AP1000 reactors a few days apart this March. SCANA Corp.’s South Carolina Electric & Gas Co. (SCE&G) marked the milestone on March 11 (Figure 2), completing concrete placement of the nuclear island basemat for its V.C. Summer Unit 2 in Fairfield, S.C., while Southern Co.’s Georgia Power completed placement for a nuclear island at its Vogtle Unit 3 nuclear expansion site near Waynesboro, Ga., on March 14 (Figure 3).

China has gone through three periods of nationwide power shortages since 1978. The previous two shortages were mostly caused by the lack of installed generation capacity. However, the third—which has severely restricted economic development—is a consequence of institutional problems that must be corrected.

It’s never fun to realize you’re wrong. But effective leaders know when to admit it and take their lumps.

Solar thermal technologies are experiencing increased popularity around the world. Three recent deployments illustrate how the technology and plant size specifics are tuned to local needs.

Microbial inhibition, as part of a robust cooling water treatment program, presents a special challenge because of the variability in makeup water sources, plant processes, and discharge permits. Failure to maintain a proper microbial inhibition program will affect your bottom line as a result of heat rate degradation.

Climate rhetoric has become increasing obsessed with "tipping points." But this sloppy metaphor risks taking good science over the cliff.

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 20th and 21st chapters, “Out of Sight and Mind” and “Holey Kansas,” the first two chapters of the “Waste Is a Terrible Thing to Mind” section.

In a milestone for the fledgling marine power sector, Alstom’s 1-MW tidal turbine (Figure 6) generated power for the first time at the European Marine Energy Centre’s tidal test site in Orkney, Scotland.

Mexico’s Federal Electrical Commission needed a safe way to train new operators at its Laguna Verde Nuclear Power Plant in Veracruz, so it developed a stand-alone process simulator that allows trainees to practice a wide variety of plant operations and responses to incidents without putting the plant itself at risk.

Far from precipitating a crisis in high-tech manufacturing, the Chinese attempt to corner the market on rare earth minerals has instead inspired some healthy competition and adaptation.

Cuadrilla Delays UK Fracking Project to Conduct More Assessments. The UK’s largest shale gas explorer, Cuadrilla Resources Holdings, on March 14 said it would delay hydraulic fracturing operations at its Anna Road project until 2014, after data it had gathered from exploration of the Bowland Basin Shale in Lancashire confirmed assessments that the 1,200-square-kilometer license […]

The number of regulated air emission constituents is increasing while the acceptable amounts for release are decreasing. In the long run, picking the most flexible multipollutant technology is surely the least cost option.
