Vermont’s attorney general on Saturday appealed a federal district court’s January decision that invalidated two Vermont statutes and ruled that Entergy could operate the Vermont Yankee nuclear plant beyond a state-mandated shutdown deadline of March 21, 2012.

Spain’s oldest nuclear reactor, Santa María de Garoña, can continue to operate safely until 2019, the country’s nuclear regulator the Consejo de Seguridad Nuclear (CSN) told the government last week. The report follows a decision last month by Spain’s recently elected conservative government to overturn a decree that would have forced the plant to close by April 2013.

In a speech today to hundreds of Southern Co. employees at that company’s Plant Vogtle in Waynesboro, Ga.—the site of the first new reactors approved in the U.S. since 1978—Energy Secretary Steven Chu said federal agencies were preparing to strengthen U.S. competitiveness in the global nuclear sector by earmarking $770 million in the Fiscal Year 2013 budget.

American Electric Power (AEP) may continue operating Big Sandy Unit 2, an 800-MW coal-fired power plant in Kentucky, if state regulators approve a 31% rate increase to help pay for pollution controls. The measure would trim the company’s planned coal retirements to 5,138 MW, not 5,909 MW, as the company had announced last June.

About 93% of total coal consumed in the U.S. in 2011 was used in the electric power sector, but electric sector coal consumption dropped by an estimated 40 million short tons—or 4% compared to 2010—as generators turned to cheaper natural gas instead, the Energy Information Agency (EIA) says.

A White House–commissioned independent review of the Department of Energy’s (DOE’s) loan portfolio concludes that the DOE could better manage its loan program and ongoing monitoring of its loan portfolio, but that the loan portfolio as a whole is expected to perform well and holds less risk than envisioned by Congress when it created and funded that program.

Eleven states filed a lawsuit in federal court on Friday to induce the Environmental Protection Agency (EPA) to promptly revise national air quality standards for fine particulate matter (PM 2.5, also known as soot) and adopt them by a certain date.

New Mexico’s Environmental Improvement Board (EIB) last week unanimously repealed a statewide cap-and-trade program adopted in 2010, when Democratic Governor Bill Richardson was in office. Current Republican Gov. Susana Martinez has been fiercely opposed to the measure.

Commissioners at the Nuclear Regulatory Commission (NRC) on Thursday voted 4–1 to direct staff to prepare a construction and operation license (COL) for Southern Co.’s two AP1000 reactors at Plant Vogtle, south of Augusta, which could become operational between 2016 and 2017. NRC Chair Gregory Jaczko, who cast the lone vote against the COL, cited the need for safety enhancements recommended as a result of the Fukushima accident last March for reasons of his dissent.

By Kennedy Maize Washington, D.C., February 13, 2012 — Environmental activists have a long record of miscalculation and misadventure. That’s been particularly true when it comes to coal. Remember acid rain? No such thing, according to a decade-long government scientific inquiry (which can’t ever quite turn itself off). Global warming? A global yawn, Al Gore […]

Just two weeks after FirstEnergy Corp. said it would close more than 2 GW of six older coal-fired power plants Ohio, Pennsylvania, and Maryland by September, the Akron, Ohio–based company today said it would retire three more plants in West Virginia. The company cited “high costs” to implement the Environmental Protection Agency’s (EPA’s) recently finalized Mercury and Air Toxics Standards (MATS).

The two-unit San Onofre nuclear power plant in the northwest corner of San Diego County, Calif., remained shut down today, more than a week after a leak from a tube in one unit released a small amount of radiation. On Thursday, regulatory officials found extensive wear on tubes in the second unit, which is offline for maintenance. Also this week, reports confirmed that a worker had fallen into and climbed out of a reactor pool at the facility.

New Hampshire’s Legislature is considering a bill that could require Public Service of New Hampshire (PSNH)—the state’s largest electric utility—to divest all 12 of its generation facilities by 2013 to complete restructuring of its electric sector. At a hearing on Thursday, PSNH staunchly opposed the measure, saying the bill could have “far-reaching economic risks, and reliability consequences for all New Hampshire business and residential customers.”

As the U.S. Nuclear Regulatory Commission (NRC) prepares to vote on Thursday on whether to approve a combined construction and operating license (COL) for Southern Co.’s proposed 2,234-MW expansion of its Vogtle nuclear plant, anti-nuclear activists are gearing up to oppose the decision. Meanwhile, Progress Energy is reportedly considering shelving its proposed Levy County, Fla., reactor.

A settlement reached between Dominion and conservation groups that was last week approved by a federal court makes the utility’s plans to shutter all four units at its 60-year-old Salem Harbor Station in Salem, Mass., by 2014 legally enforceable.

Renewable power prices in California surged from 5.4 cents/kWh in 2003 to 13.3 cents/kWh in 2011. However, they are slated to fall as new contract bids submitted to utilities last year were estimated at about 30% lower than in 2009, a new report from the California Public Utilities Commission (CPUC) suggests.

More renewable power capacity was installed than ever before in the European Union (EU) during 2011, the European Wind Energy Association (EWEA) says in a new report published on Monday. The EU saw a 3.9% increase in power capacity compared with 2010, much of which was driven by renewable power capacity increases. In 2011, the EU added 37.7% more renewable power capacity than in 2010.

The Environmental Protection Agency (EPA) on Dec. 21 issued its final Mercury and Air Toxics Standards (MATS), which will require about 40% of all coal-fired power plants in the U.S. to deploy pollution control technologies to curb emissions of mercury and other air pollutants such as arsenic and cyanide within three years.

Using nanoparticles of a copper compound to develop an inexpensive and durable high-powered battery electrode could be the breakthrough solution to the problem of sharp drop-offs in the output of wind and solar systems, scientists at Stanford University say.

In a power plant, the primary use of vacuum systems is to remove air and other noncondensable gases from the shell side of the condenser in order to maintain design heat transfer and thus design vacuum. If holding condenser vacuum is a persistent problem, one often-overlooked cause is an inadequately sized vacuum system.

A new report commissioned by the Coalition for Affordable Solar Energy (CASE)—an alliance of about 70 solar companies whose rallying message declares global competition has made solar energy a reality around the world—finds that if the U.S. government imposes a 100% tariff on imported solar PV cells and modules from China, the nation could see as many as 50,000 net lost jobs over the next three years.

With the 2012 election year upon us, it promises to be an interesting time for energy politics and policy. Here are 12 (really 13 because of some creative headline writing) issues that will keep the sector hopping this year.

A semi-submersible structure supporting a 2-MW wind turbine was towed nearly 350 kilometers (217.5 miles) to water depths of about 35 meters (114.8 feet) into open Atlantic waters and deployed off the coast of Aguçadoura, Portugal, last November.

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work. Determining the design changes required in the valve and fluid system to prevent the vibration from occurring requires advanced analytical techniques.

Citing newly finalized and proposed environmental regulations that could make costs uncertain, FirstEnergy Corp. on Thursday said it would shutter six older coal-fired power plants with capacities totaling 2,689 MW in Ohio, Pennsylvania, and Maryland by September. The same uncertainties prompted a major backer of a $2 billion coal-fired power plant planned for Washington County in Georgia to pull its funding.

At year end 2011, as Americans emptied their wallets at the gas pump and crude oil reached almost $100 a barrel, OPEC kingpin Saudi Arabia reported an $81.6 billion 2011 budget surplus.

Last December, as Spain’s national carbon capture and storage (CCS) research laboratory Fundación Ciudad de la Energía (CIUDEN) began a much-watched testing phase of oxycombustion in its 30-MWth circulating fluidized bed (CFB) boiler in Cubillos del Sil, Vattenfall scrapped the €1.5 billion ($2 billion) Jänschwalde CCS demonstration project that it had planned to build and begin operating by 2015 in the German federal state of Brandenburg.

The Nuclear Regulatory Commission (NRC) on Tuesday urged owners of 62 nuclear power plants in the Central and Eastern U.S.—facilities housing 96 of the nation’s 104 commercial nuclear reactors—to reevaluate seismic hazards using a new seismic model and information from a recent report.

The U.S. Court of Appeals for the District of Columbia Circuit temporarily blocked the Cross-State Air Pollution Rule (CSAPR) just two days before it was set to go into effect. The federal court ordered the Environmental Protection Agency (EPA) to continue administering the previously promulgated Clean Air Interstate Rule (CAIR) until a final decision can be made on the merits of the rule, likely this summer or fall.
