Duke Energy and Progress Energy received conditional approval for their merger from the Federal Energy Regulatory Commission (FERC) on June 8. The companies plan to close their merger, which would create the nationís largest utility, by the targeted date of July 1.

Mayors of more than 90 U.S. cities have signed a letter to Environmental Protection Agency (EPA) Administrator Lisa Jackson voicing their support for the recent EPA Mercury and Air Toxics Standards for Power Plants (MATS).

All indications from Wednesday’s Senate Environment and Public Works Committee joint hearing are that Dr. Alison Macfarlane will been confirmed as the new chair of the Nuclear Regulatory Commission (NRC) and that Commissioner Kristine Svinicki will be approved for a second term. Macfarlane, a nuclear waste expert who served on the White House’s Blue Ribbon Commission on Americaís Nuclear Future, was nominated by President Barack Obama last month after Chairman Gregory Jaczko, whose leadership style was described by commissioners from both political parties as abusive, resigned May 21.

Regulated utility South Carolina Electric & Gas (SCE&G) last week filed plans with the Public Service Commission of South Carolina to retire up to six coal-fired units—a total capacity of 750 MW—by 2018. The units are some of the utility’s “oldest and smallest,” and it would not be a “good business decision” to add costly environmental control equipment to these plants, SCE&G said.

American Electric Power (AEP) last week temporarily withdrew a $1 billion plan to retrofit its 49-year-old Big Sandy coal-fired plant near Louisa, Ky., from the Kentucky Public Service Commission (PSC), saying it wanted to reevaluate alternatives to meeting the company’s obligations under the recently finalized federal Cross-State Air Pollution Rule, the Mercury and Air Toxic Standard, and other environmental standards.

A federal court on Friday ruled that collection of a fee by the Department of Energy that totaled nearly $750 million a year from nuclear generators for nuclear waste disposal since 1983 was “legally defective” because development of the Yucca Mountain permanent spent fuel waste facility had been discontinued. But in lieu of suspending the fee, the court ordered the DOE to conduct a reevaluation of the Nuclear Waste Fund within six months.

The Environmental Protection Agency (EPA) last week issued a Notice of Data Availability (NODA) as a supplement to its April 2011 proposed rule for cooling water intake structures at all existing power facilities as part of section 316(b) of the Clean Water Act.

A report released on Friday by consultants at the Brattle Group concludes that tripling peak wholesale power prices in Texas (from $3,000/MWh to $9,000/MWh by 2015), as is being considered by Texas utility commissioners and grid operators to encourage power plant construction in the power-strapped state, would only raise the region’s reserve margin to 10% above peak demand—less than the 13.75% reserve margin recommended by federal regulators.

Nearly three-quarters of the 74 transmission line outages were caused by fallen trees during a snowstorm that hit the Northeast in October 2011 and shut off the lights for more than 3.2 million homes and businesses, concludes a report released jointly by the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corp. (NERC).

The growing lack of cooling water resources could decrease power generating capacity in the U.S. by between 4% and 16% and between 6% and 19% in Europe between 2031 and 2060, and the likelihood of extreme drops in generation as a result will almost triple, suggests a new study by European and University of Washington (UW) scientists.

PPL Corp. last week shut down Unit 2 of its Susquehanna nuclear power plant in Luzerne County, Pa., for a planned inspection of its turbine. Unit 1 of the two-reactor plant was shut down after workers in April found cracks similar to damage discovered and repaired in 2011.

By Kennedy Maize Washington, D.C., 3 June 2012 — An international effort is underway to give control and governance of the Internet to a United Nations agency, with implications for ways that U.S. utilities might implement smart grid technologies. Led by Russia and China, the plan to turn the Internet over to the International Telecommunications […]

The cybersecurity needs of the electric power industry are unique, due to the critical nature of the product and the wide range of technologies that must be considered—from complex, modern industrial control systems to aging infrastructure elements.

The U.S. Environmental Protection Agency has regulated particulate matter as an air pollutant for more than 40 years. Over time, PM regulations and testing methodologies have become more complex, with the focus shifting to smaller particle size fractions and the inclusion of the condensable form of PM. New developments make navigating the permitting and compliance process efficiently more important than ever.

Combining concentrating solar power (CSP) with thermal energy storage shows promise for increasing grid flexibility by providing firm system capacity with a high ramp rate and acceptable part-load operation. When backed by energy storage capability, CSP can supplement photovoltaics by adding generation from solar resources during periods of low solar insolation.

Dr. Daniel Yergin, chairman of IHS Cambridge Energy Research Associates, is a Pulitzer Prize–winning author; leading authority on energy, international politics, and economics; and a recipient of the United States Energy Award for “lifelong achievements in energy and the promotion of international understanding.” He recently spoke with POWER about his latest book—and more.

POWER marks its 130th year of service to the power generation industry with this issue. Instead of cake for the staff, we decided to celebrate the milestone in a way that will benefit our readers and supporters for many years to come.

The March 2011 Japanese earthquake and tsunami that destroyed a number of Japanese power plants—most notably, four nuclear units—hit quickly. Almost as speedy were calls to take all other nuclear units out of service for safety reviews. What will take much longer is developing a new, sustainable energy plan to fill the generation gap left by a potential total lack of nuclear power.

Large circles represent technical reserves and small (blue) circles represent potential reserves of shale gas, both in trillion cubic feet.

Online learning is opening up new opportunities for those unable to attend classes on campuses. Bismarck State College and the University of North Dakota, for example, offer innovative online courses and degree programs to students who want successful careers in the electric power industry.

Massive offshore shale gas reserves exceeding 1,000 trillion cubic feet (tcf) discovered in the UK in April could catapult that country to the top ranks of global producers.

Combined cycle power plants use fuels and other materials that can cause fires or explosions in the combustion turbine, ducting, or heat recovery steam generator. Purging that equipment with ambient air to displace residual combustible gases before starting is a normal safety practice. But when plants are cycled, the disadvantages of purging often outweigh the advantages.

This overview of Japan’s nuclear fleet is a web supplement to the June 2012 feature “Japan Scrambles to Revamp Its Electricity Sector.” For a list of major Japanese generating companies, see Figure 1 in that article.

Denmark’s parliament in late March agreed to a new energy strategy seeking to wean the country off oil and gas. It could result in the Nordic country cutting its greenhouse gas emissions 34% by 2020, compared to 1990 levels, and decreasing energy consumption by more than 12%, compared to 2006.

Most power plants use some form of condenser performance-monitoring protocol. Some of those protocols are deficient because the proper instrumentation is not installed to collect the necessary data. Three case studies illustrate how collecting good condenser performance data enabled plant staff to troubleshoot problems and make good plant performance improvement decisions.

A model of Switzerland’s energy future to 2050 that abides with the country’s post-Fukushima decision not to build any new nuclear power plants suggests the phase-out could cost nearly $33 billion.

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 second chapter, “Manhattan Transfer,” which covers the open fight for control of the development of nuclear power between the newly created Atomic Energy Commission and the military services, with the politicians playing both sides against each other.

Oxyfuel technology has been retrofitted at a 700-MW coal-fired power plant in Queensland, Australia, and is now capturing carbon dioxide from one of the plant’s six steam boilers.
