A new study from the Government Accountability Office (GAO) says the Nuclear Regulatory Commission (NRC) should reevaluate the formula with which it calculates nuclear reactor decommissioning costs. In an analysis of 12 of the nation’s 104 reactors, decommissioning costs calculated for five reactors were 76% less than what would be required, Congress’ investigative arm says.

Integrys Energy Group subsidiary Wisconsin Public Service Corporation (WPS) on Monday filed for a Certificate of Authority (CA) from the Public Service Commission of Wisconsin (PSCW) to install Regenerative Activated Coke Technology (ReACT) at its 321-MW Weston 3 plant.

Spanish wind turbine manufacturer Gamesa on Monday said it would start the permitting process for the installation of its first offshore prototype, the 50-Hz G128-5.0 MW at Arinaga Quay in Spain’s Gran Canary Island—not Cape Charles, Va., as it had initially proposed. The decision was driven by technical and wind resource considerations, offshore market trends, and investment return criteria, the firm said.

Canadian energy firms TransAlta, Capital Power, and Enbridge last week scrapped plans for the much-watched Project Pioneer, a joint effort the companies were to undertake with the Canadian federal government and Province of Alberta to demonstrate commercial-scale viability of carbon capture and storage technology (CCS).

Duke Energy and some of the Indiana’s key consumer groups on Friday reached a settlement agreement that resolves a disagreement concerning the utility’s consumer-paid cost overruns for its 618-MW integrated gasification combined cycle (IGCC) plant at Edwardsport, Ind. The $3.3 billion coal-fired plant is almost complete and on schedule to begin operations this fall.

The nation’s complex, patchwork system of regional and local power plants, power lines, and transformers is in the worst shape it has ever been, with 70% of transmission lines and power transformers aged more than 25 years, and 60% of the nation’s circuit breakers currently more than 30 years old, suggests new report from the American Society of Civil Engineers (ASCE). At least $566 billion will be needed to revitalize the grid through 2020, the group warns.

Small-scale technology tests by the U.S. and Japan in the North Slope of Alaska have extracted a steady flow of natural gas from methane hydrates, the U.S. Department of Energy (DOE) said on Wednesday. If new research efforts to conduct long-term production tests in the Arctic and Gulf Coast are successful, they could unlock a “vast, entirely untapped resource” that would hold significant enormous potential for U.S. energy security, the agency said.

The events that left 2.7 million power customers in Southern California, Arizona, and Baja California in the dark on Sept. 8, 2011, stemmed from operating in an unsecured state due to inadequate planning, a lack of observability, and awareness of system operating conditions on the day of the event, the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC) concluded in a report released on Tuesday.

Costs for Progress Energy’s two news reactors proposed for Levy County have surged to between $19 and $24 billion, and the first unit could come online almost three years after initially planned, the company said in a statement on Monday. The North Carolina–based company had previously said the first unit at Levy would enter service in 2021 at an estimated cost of $17 billion to $22 billion.

Member states of the European Union (EU) will get a few more months to complete tests on their 147 nuclear power plants, and a final stress test report will be completed this fall—not this summer as initially expected— before any new nuclear safety laws are proposed, EU Energy Commissioner Günther Oettinger said last week.

An agreement reached on Tuesday by Public Service Co. of Oklahoma (PSO) and the Environmental Protection Agency, Oklahoma State, and the Sierra Club will force the American Electric Power (AEP) subsidiary to eventually retire two coal-fired generating units at its Northeastern Station in Oologah, Okla.

About 46% of power company executives in Europe and North America recently surveyed by PricewaterhouseCoopers (PwC) predict an increased risk of blackouts up until 2030, citing worries about the affordability and the pace of infrastructure investment, and future energy security.

Coal generation, as a percentage of total power output in the U.S., declined steadily to 39% at the end of 2011 from about 51% in 2002, while generation from natural gas–fired combined cycle plants grew to more than 20% from 10% over the same period, the Federal Energy Regulatory Commission (FERC) said on Friday as it released its annual assessment for U.S. energy markets.

The latest in a string of nuclear plants beset by technical troubles is PPL Corp.’s Susquehanna Nuclear Plant in northeastern Pennsylvania. The company said on Tuesday that a follow-up inspection of the Unit 1 main turbine at that two-reactor facility revealed “indications of cracks in blades” that are similar to damage discovered and repaired in 2011.

Activity kicked up in Washington in the past week, where members of the House of Representatives introduced a number of energy bills and passed a key amendment that could give states—not the Environmental Protection Agency (EPA)—control over coal ash regulation.

The Mississippi Public Service Commission (PSC) on Wednesday voted 2–1 to approve Mississippi Power’s $2.4 billion integrated gasification combined cycle (IGCC) project proposed for Kemper County, saying it continued to find that the 582-MW project was the “best alternative” to meet the state’s future power demand. The state’s Supreme Court had reversed the PSC’s previous approval of the plant in March, ruling that it did not cite detailed evidence for a Certificate of Public Convenience and Necessity.

The Maine Public Utilities Commission (PUC) on Wednesday approved primary contract terms of power purchase agreements (PPAs) for Ocean Renewable Power Co.’s (ORPC’s) 4-MW Maine Tidal Energy Project in Washington County and directed three investor-owned utilities to negotiate 20-year PPAs with ORPC. Those deals could be the first long-term PPAs for tidal energy in the U.S.

During the Clean Energy Ministerial in London over the next few days, the U.S. and the UK will agree to collaborate in the development of floating wind technology designed to generate power in deep waters currently off limits to conventional turbines, but where the wind is much stronger, the UK’s Department of Energy and Climate Change (DECC) announced this week.

PPL Montana on Monday filed suit against the Environmental Protection Agency (EPA) to block it from releasing information about its 2,094-MW coal-fired Colstrip power plant to environmental groups that had requested the data via the federal Freedom of Information Act.

The Environmental Protection Agency’s (EPA’s) final Mercury and Air Toxics Standards (MATS) quietly took effect on Monday, kicking off the three-year compliance period mandated under the Clean Air Act. Several more groups filed suit before the filing deadline for legal challenges on April 16, including the Utility Air Regulatory Group (UARG), Colorado’s Tri-State Generation and Transmission Association, and the American Public Power Association (APPA).

A three-judge panel at the U.S. Court of Appeals for the District of Columbia Circuit on Friday heard oral arguments in a case challenging the Environmental Protection Agency’s (EPA’s) Cross-State Air Pollution Rule (CSAPR). A decision in the case—which stayed implementation of the first phase of the rule on Jan. 1—is expected as early as June or July.

The Environmental Protection Agency (EPA) on Wednesday finalized the first federal standards that will curb smog-forming chemicals and other substances that may be released into the air during fracking, the increasingly popular drilling technique that promises to revolutionize natural gas production.

In a move that has been seen as the first step toward partially re-regulating Maryland’s power market, state regulators last week ordered CPV Maryland to build a new $500 million gas-fired power plant in the Charles County town of Waldorf and directed three of the state’s largest power companies to buy power produced from the plant.

Last week saw the release of three reports from influential wind industry groups. The Global Wind Energy Council (GWEC) foresaw annual global market growth rates of about 8% for the next five years, though it cautioned of a “substantial dip” in 2013. The American Wind Energy Association (AWEA) urged congressional renewal of wind tax credits, and the European Wind Energy Association (EWEA) called for more binding post-2020 policies to ensure sector growth in the European Union.

More than 2,500 dams in the U.S. provide 78 GW of conventional and 22 GW of pumped-storage hydropower. But the nation also has more than 80,000 dams that do not produce electricity—facilities that, if outfitted with hydroelectric power plants, could generate an estimated 12 GW and increase existing U.S. conventional hydropower capacity by roughly 15%, the Department of Energy (DOE) says in a new report,

Passage of the a federal Clean Energy Standard (CES) or Renewable Energy Standard (RES) in the near future is highly unlikely given the current political climate and upcoming election cycle, an analysis from research consulting firm Wood Mackenzie shows.

China’s state-owned China National Nuclear Corp. (CNNC) on Monday announced it had fully completed and commissioned the fourth unit of the Qinshan Nuclear Power Phase II expansion nearly 60 days ahead of schedule.  The domestically engineered unit is China’s 15th operating nuclear power reactor.

Southern California faces a grim summer with electrical generation capacity stretched to the limit, as any prospects for a quick restart of the idled San Onofre Nuclear Generating Station (SONGS) now appear all but dead.

Completion of the Tennessee Valley Authority’s (TVA’s) second Watts Bar reactor will cost nearly double the $2.49 billion price estimated in 2007 and take much longer than the projected 60-month completion timeframe, a construction review undertaken by the federally owned corporation has revealed. TVA management pointed to mismanagement and faulty execution as reasons for the discrepancy.

Under a settlement agreement reached between environmental groups on Tuesday and Power4Georgians, the consortium of four electric membership cooperatives (EMCs) in Georgia will continue development of its $2.1 billion coal-fired Plant Washington but will shelve plans for its proposed 850-MW supercritical Ben Hill plant.
