A123 Systems, maker of an advanced lithium iron phosphate battery and energy storage systems on Tuesday filed voluntary petitions for reorganization under Chapter 11, as Satcon, a provider of utility-grade power conversion solutions for the renewable energy sector, filed for bankruptcy on Wednesday.

Southern California Edison (SCE) last week outlined measures it had completed to correct issues identified in the steam generator tubes of its beleaguered San Onofre Nuclear Generating Station (SONGS) Units 2 and 3, as requested by the Nuclear Regulatory Commission (NRC). As part of a restart plan also submitted to regulators last week, the company proposed to restart Unit 2 at 70% power for a five-month trial period.

PPL Corp. on Friday said it was preparing to shut down Unit 1 of its two-reactor Susquehanna Nuclear Plant in northeastern Pennsylvania for additional turbine inspection and to confirm data provided by new instrumentation that could finalize a plan to resolve turbine blade cracking that has afflicted both reactors at the plant.

The Environmental Protection Agency (EPA) on Friday appealed a federal court decision handed down on Aug. 21 that vacated the agency’s July 2011–finalized Cross-State Air Pollution Rule (CSAPR) because, the court said, it violated federal law. The EPA is now seeking a rehearing en banc that would involve all eight judges that serve at the U.S. Court of Appeals for the D.C. Circuit.

Pennsylvania’s Department of Environmental Protection (DEP) on Wednesday issued an air quality plan approval for a project to build the state’s first power plant to run at least partially on locally sourced Marcellus Shale gas. Moxie Energy’s proposed 936-MW plant in Asylum Township, Bradford County, uses two power blocks that will each consist of a combustion gas turbine and a steam turbine.

Czech utility ÄŒEZ on Wednesday told AREVA that a bid submitted to build two new EPR units at the Temelín Nuclear Power Plant—a site that already houses two VVER-1000 reactors built in 2000 and 2003—has been disqualified because it failed to fulfill “some other crucial criteria” defined in the tender. The decision, which AREVA said it would appeal, means only Westinghouse and an AtomStroyExport-led consortium remain as contenders for that project contract.

Global nuclear power capacity is expected to grow nearly 25% from current levels to 456 GW by 2030 according to low projections, International Atomic Energy Agency (IAEA) Director General Yukiya Amano told conference attendees in Kyoto, Japan, on Monday. The Fukushima Daiichi accident was a "big wake-up call" on nuclear safety, but it would not mean "the end of nuclear power," he said as he called on Japan to engage in dialogue about its stated policy to shut down all existing reactors by 2040.

An update to a 2010 analysis on the market and regulatory outlook facing coal-fired power plants in the U.S. from economists at The Brattle Group forsees that 59 GW to 77 GW of coal plant capacity are likely to retire over the next five years—about 25 GW more than previously estimated—due primarily to lower expected natural gas prices.

Repair of the damaged containment structure at Progress Energy’s Crystal River nuclear power plant in Florida will likely hover at $1.5 billion, but it could escalate to as much as $3.5 billion and take eight years to complete in the worst-case scenario, an independent review of a potential repair plan shows.

A bill introduced on Friday by a ranking member of the U.S. House Science, Space, and Technology Committee seeks to reform the Environmental Protection Agency’s (EPA’s) Science Advisory Board (SAB) and its sub-panels to deal with concerns about “balance, impartiality, independence, and public participation.”
