A settlement reached between Duke Energy and conservation groups on Tuesday legally binds the North Carolina–based utility to shutter 1,667 MW of coal-fired capacity from aging plants and tighten pollution controls at the new 825-MW pulverized coal unit that is scheduled to come online this year at its Cliffside Steam Station on the Rutherford/Cleveland County line in North Carolina.

Vestas, the world’s largest wind turbine manufacturer, plans to lay off 2,355 employees (about 10% of its workforce), reduce its fixed costs by more than €150 million ($192 million), reorganize management, and close one of its 26 factories in preparation for a potential slowdown in the U.S. wind market in case the production tax credit is not extended at the end of 2012, the Danish firm said on Thursday.

A lease-purchase transaction for a new combined cycle plant in Rogersville, Tenn., completed by the Tennessee Valley Authority (TVA) on Tuesday could provide the U.S. government–owned corporation $1 billion in financing to support completion of the 1,260-MW Bellefonte Nuclear Plant in Hollywood, Ala., by 2020.

Électricité de France (EDF), Constellation Energy’s partner in five nuclear plants on three sites in Maryland and New York and a 7.2% owner of Constellation shares, on Tuesday withdrew its opposition to a $7.9 billion merger between Baltimore-based Constellation and Chicago-based Exelon Corp. The French company said it had reached an agreement with Exelon to protect the “operational autonomy” of the Constellation Energy Nuclear Group (CENG).

Two reports assessing wave and tidal resources in the U.S. released today by the Department of Energy (DOE) suggest that water power—including conventional hydropower and wave, tidal, and other resources—could provide 15% of the nation’s electricity by 2030.

By Kennedy Maize   Washington, D.C., January 12, 2012 — The ancient English idiom “It’s an ill wind that blows no good” takes on specificity following an article in tomorrow’s Science magazine. The article argues that increased winds in the Southern Ocean, likely caused by a changing global climate, are a boon to the wandering […]

The Federal Energy Regulatory Commission (FERC) and the National Association of Regulatory Utility Commissioners (NARUC), an organization representing state public service commissioners, joined forces to launch a forum to explore reliability issues that could crop up as a result of new and pending environmental rules for the power sector.

A new report published by the Institute for Electric Efficiency (IEE) finds that electric energy efficiency savings are on the rise in the U.S.—and that electric utilities accounted for a vast majority of ratepayer-funded electric efficiency expenditures in 2010.

Two of Vermont’s largest power distribution companies on Monday filed suit against Entergy Vermont Yankee, owner of the aging 620-MW Vermont Yankee Nuclear Plant in Vernon, Vt., alleging that Entergy’s faulty maintenance of cooling towers at the plant in 2007 and 2008 had cost them $6.6 million in increased power costs and lost capacity payments.

The Bonneville Power Administration (BPA) on Friday asked the Federal Energy Regulatory Commission (FERC) for a rehearing of a decision it made last December, when it ruled the Pacific Northwest–based federal agency discriminated against wind generators after the BPA curtailed wind power when high river flows hit the region last May and June.

New policy on nuclear safety regulation could limit the operational life of Japanese nuclear plants to 40 years and require operators to prepare for severe accidents, Japan’s government announced on Friday. If the new law is passed, at least 13 plants, as well as the six Fukushima Daiichi reactors, will be shut down per the […]

Myanmar’s government on Monday cancelled construction of a 4,000-MW coal-fired power plant proposed by Thai company Italian-Thai Development on public concerns about the plant’s environmental impact.

The newest initiative to protect the nation’s power grid from cyber attacks is the “Electric Sector Cybersecurity Risk Management Maturity” project, led by the U.S. Department of Energy (DOE) and Department of Homeland Security (DHS). The project is expected to leverage the insight of private and public sector grid experts and build on existing cybersecurity measures and strategies.

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.

An AES Corp. subsidiary that owns more than 1,000 MW of coal-fired capacity at six facilities in New York last week filed for Chapter 11 bankruptcy protection, citing falling power prices and heightened costs from compliance with environmental regulations.

The Massachusetts Supreme Judicial Court (SJC) last week upheld a decision by the state’s Department of Public Utilities (DPU) that a Power Purchase Agreement (PPA) between Cape Wind and utility National Grid would be a cost-effective use of ratepayer money. The decision means Cape Wind is closer to building North America’s first offshore wind farm.

Pennsylvania’s Sunbury Generation, a company that owns the Shamokin Dam plant—the nation’s oldest coal-fired power plant—last week reportedly said it would close five of its six coal-fired generation units and replace them with two natural gas–fired turbines by 2015. The company cited stricter regulations on power plant emissions.

The Department of the Interior (DOI) on Thursday approved a 275-MW solar plant in California and a 104-MW wind farm in Oregon that will be built on private lands and use power lines that cross public lands to connect to their respective grids. The projects are the 26th and 27th renewable projects approved by the DOI in the past two years.

The Bonneville Power Administration (BPA) plans to begin construction of six new 500-kV overhead transmission lines at the Grand Coulee Dam—the nation’s largest hydropower facility—next month, the public service organization said last week. The new lines will help ensure continued safe and reliable transmission of power between Grand Coulee Dam’s third power plant and the BPA’s vast high-voltage power grid.

PJM Interconnection on Sunday began operational control of the transmission systems of Duke Energy Ohio and Duke Energy Kentucky, both subsidiaries of Duke Energy, and began administering open, competitive wholesale electricity markets in those areas, the regional grid operator said on Jan 1.

The POWER editorial staff’s picks for the most significant stories of 2011.

After more than a decade debating whether to pass a carbon-limiting law, Australia’s Senate in November voted in a landmark bill that will impose a price on carbon emissions. The country, which accounts for just 1.5% of global carbon emissions, but which is the world’s highest emitter per capita because 80% of its power comes […]

Xenon has introduced the T925 Wireless Cellular Controller for connecting remote sites with central control and monitoring stations through cellular networks. A T925 remote communications network eliminates the need to make hardwired Ethernet connections to the Internet or an intranet at each remote site and the central control and monitoring station. The network operates from […]

At home and abroad, U.S. military microgrid and smart grid projects are driven by energy security concerns. The pace of such projects, however, can be slow, and the potential for civilian grids to benefit from lessons learned and technologies developed for these important installations may be limited.

The U.S. Nuclear Regulatory Commission (NRC) in October directed staff to begin implementing seven safety recommendations put forth by the federal body’s Near-Term Task Force on lessons learned from the nuclear accident at Tokyo Electric Power Co.’s Daiichi power plant in Japan’s Fukushima prefecture last March. The recommendations affecting all 104 nuclear reactors (Figure 1) […]
