Exelon Corp. and Constellation Energy on Monday completed their long-awaited $7.9 billion merger. The combined company, which retains the Exelon name, has a market cap of $34 billion, a 35-GW generation fleet, and activity in 47 U.S. states and some Canadian provinces. It is now the biggest power utility in the U.S.—until the $26 billion Duke-Progress merger is completed, at least.

A bill passed with a bipartisan vote of 265–154 by the U.S. House last week seeks to fast-track permitting for hydropower installations of 1.5 MW or less in canals and pipelines by minimizing environmental reviews.

The Nuclear Energy Institute (NEI) last week detailed its “FLEX” response strategy, a program that calls for more safety and emergency response equipment at each of the nation’s 104 commercial nuclear reactors. According to the trade industry group, “The initiative commits every U.S. company operating a nuclear energy facility to order or enter into contract for a plant-specific list of emergency equipment by March 31.”

A report released today by the Solar Energy Industries Association (SEIA) claims that though the U.S. solar power sector was hard hit by policy changes and plunging global prices of photovoltaic (PV) panel prices, it installed 1,855 MW of PV capacity last year—more than doubling the previous annual record of 887 MW set in 2010.

The Department of Energy has made $15 billion in loan guarantees and conditionally committed to another $15 billion, but its loan guarantee program lacks much-needed consolidated data on application status, which could make easier efficient management and program oversight, a new report from the Government Accountability Office (GAO) has found. The report was released on Monday, just before Energy Secretary Steven Chu defended the Obama administration’s loan programs before a Senate committee.

Edison International last week said it was unable to secure financing for more than $700 million in scrubbers and other air pollution equipment required by state and federal regulations to continue operating the beleaguered 1,884-MW Homer City Generating Station Pennsylvania. The news comes on the heels of the announced closure of the firm’s two Chicago coal-fired power plants by 2014.

The Bonneville Power Administration (BPA) on Tuesday submitted a revised open access transmission tariff to the Federal Energy Regulatory Commission (FERC), addressing situations that occur mostly in the springtime when the Columbia River surges and there is too much power available for delivery.

A new report released last week by the North American Electric Reliability Corp. (NERC) finds that loss of reactive power is the most likely outcome from a severe solar storm centered over North America.  Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes.

A report presented to China’s legislature on Monday by Premier Wen Jiabao could have positive implications for the country’s centrally owned grid and nuclear firms, but they could leave "thermal generators out in the cold," experts said.

In the keynote address to the CERAWeek 2012 conference in Houston on Tuesday, Helge Lund, president and CEO of Norway-based Statoil, urged the oil and gas industry to embrace a greater sense of responsibility in facing its current and future challenges.

Three Memorandums of Agreement (MOA) between the U.S. government entities and private companies signed on Friday will seek to leverage Savannah River’s land assets and energy facilities near Aiken, S.C., to support potential private sector development, testing, and licensing of prototype small modular reactor (SMR) technologies.

Energy Secretary Steven Chu on Thursday announced a planned six-year $180 million initiative—including an initial commitment of $20 million this year—to accelerate the deployment of four offshore wind power projects in the U.S. The funds are subject to congressional appropriations.

Senate Energy and Natural Resources Chairman Jeff Bingaman (D-N.M.) on Thursday introduced the Clean Energy Standard Act (CES) of 2012, a bill that could require some utilities around the nation to ensure at least 24% of all power sold in 2015 could be defined as “clean energy.” Under the bill, by 2020, that percentage would grow to 39%, by 2025, 54%, and by 2035, 84%.

A federal appeals court on Thursday ruled that Albuquerque, N.M.–based PNM could not delay enforcement of an Environmental Protection Agency (EPA) mandate that would force it to install pollution controls at its 1,800-MW coal-fired San Juan Generating Station near Farmington, N.M., while the issue is considered by the court.

Houston-based GenOn is the latest of a string of power firms to announce planned power plant closures in Pennsylvania, Ohio, and New Jersey. The company formed in December 2010 through the merger of Mirant Corp. and RRI today announced it would deactivate 3,140 MW of generating capacity in PJM’s operational region between June 2012 and May 2015, citing insufficient “forecasted returns on investments necessary to comply with environmental regulations.”

In a landmark ruling that some analysts are calling a “major victory” for the hydropower sector, a unanimous U.S. Supreme Court last week overturned a March 2010 decision by the Montana Supreme Court that entitled the state of Montana to collect $89 million in back rent from PPL Montana for that company’s use of state-owned riverbeds for long-standing hydropower plants.

An updated roadmap for the smart grid is now available from the National Institute of Standards and Technology (NIST), which recently finished reviewing and incorporating roughly 240 comments on the draft version that was released for public comment in October last year.

A severe blaze that broke out on Monday morning at RWE npower’s 750-MW Tilbury power station—a plant recently converted from coal to biomass that has been billed as a pioneer in its use of that technology—raged for two days, until Tuesday, when it was brought under control. All employees at the plant have been accounted for.

A proposed rule issued on Monday by the Environmental Protection Agency (EPA) will not change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs. However, it includes revisions to the permitting program that would provide some flexibility in how compliance is achieved with GHG emission caps.

The shield building of FirstEnergy Nuclear Operating Co.’s (FENOC’s) Davis-Besse Nuclear Power Station in Oak Harbor, Ohio, lacked an exterior weatherproof coating, and this allowed moisture from the blizzard of January 1978 to migrate into the concrete and cause the hairline wall and subsurface cracks discovered during a reactor head replacement outage at the facility last fall, a root cause analysis report indicates.

The Bonneville Power Administration (BPA) last week proposed a $428 million upgrade to the Pacific Direct Current Intertie, an 846-mile overhead transmission line that delivers hydropower and wind power between the Northwest and California. The line is one of the world’s longest and highest capacity transmission links.

A study conducted by the Oak Ridge National Laboratory (ORNL) and released by the Electric Power Research Institute (EPRI) on Tuesday shows that enough physical and geographical locations exist in the U.S. to site 952 GW of new advanced coal with carbon capture and storage (CCS), dry-cooled and water-cooled concentrating solar power (CSP), and large and small nuclear reactors. The study also suggests that plant siting opportunities exist for compressed air energy storage (CAES) in 38% of the U.S.

A legal challenge to the Obama administration’s decision not to issue proposed ozone standards last fall was dismissed on Friday after a three-judge panel with the U.S. Circuit Court of Appeals for the District of Columbia held that it did not have jurisdiction to review the action.

Eleven U.S. nuclear plants received a Request for Information (RFI) from the Nuclear Regulatory Commission (NRC) on Friday asking for analyses of the effects of “thermal conductivity degradation” for nuclear fuel developed by Westinghouse under certain postulated accident conditions.

UK power company Drax has canceled a 290-MW biomass power plant proposed for construction in North Yorkshire, citing high costs for transporting fuel to the £1.4 billion ($2.19 billion) inland plant and a lack of financial and regulatory support from the UK government.

The UK and France on Friday signed a landmark agreement to strengthen cooperation on civil nuclear energy between the two countries, reaffirming their enthusiasm for nuclear power. The agreement, made nearly a year after the Fukushima accident in Japan, seeks to help the countries achieve energy security within the European Union’s low-carbon energy policy framework.

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.

Publication of the Environmental Protection Agency’s (EPA’s) final Mercury and Air Toxics Standards (MATS) in Thursday’s Federal Register means that the three-year compliance period mandated under the Clean Air Act will begin in 60 days, on April 16, 2012. Thursday’s publication also kicked up a storm of reactions and prompted several legal challenges.

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.
