A federation of Japanese power companies last week reportedly asked member companies to “rethink plans” to power the country’s nuclear plants with mixed oxide (MOX) fuel because many plants are unlikely to launch plutonium generation within the next three years, as expected.

European heavyweights Alstom and Siemens could vie to bid for AREVA’s transmission and distribution (T&D) business if the French state-controlled giant puts it up for sale to plug a €12 billion gap and finance its investments, market research group Frost & Sullivan said last week.

The Nuclear Regulatory Commission (NRC) last week renewed the operating licenses for Units 1 and 2 of the 2,301-MW Vogtle nuclear power plant in Waynesboro, Ga., for an additional 20 years, making them the 53rd and 54th reactor licenses renewed by the federal regulatory body.

Entergy subsidiaries on Thursday announced they had completed three major transmission projects in south Louisiana, including a rebuild of a line in Plaquemines Parish that had been destroyed in Hurricane Katrina and two upgrades to transmission lines that run through the Baton Rouge to New Orleans corridor.

By Kennedy Maize After almost unrelenting hype, skepticism about plug-in hybrid cars is beginning to emerge in the mainstream media. It’s a good thing, as much about the much-ballyhooed vehicles, particularly the General Motors Chevy Volt, doesn’t withstand serious business or technical scrutiny. In early June, Jim Motavalli at the “Wheels” blog at the New […]

The Tennessee Valley Authority (TVA) on Friday appealed a January 2009 ruling by the Fourth Circuit Court of Appeals that declared emissions from the public company’s coal plants in eastern Tennessee and Alabama a public nuisance in North Carolina. Experts say that the landmark decision could pave the way for public nuisance suits to regain prominence in climate change–related litigation.

The U.S. District Court for the Southern District of Indiana on Friday ordered Duke Energy to permanently shut down three units—a combined capacity of 265 MW—at the company’s Wabash River Station in Indiana within three months.

The Canadian government is restructuring the Atomic Energy of Canada Ltd. (AECL) and may sell a stake of the company to the private sector to leverage the country’s long-term investment in nuclear energy.

The American Clean Energy and Security Act, now bound for debate on the House floor after clearing the House Committee on Energy and Commerce, contains four key changes that will secure the coal industry and thousands of jobs that coal provides, U.S. Rep. Rick Boucher (D-Va.) said Friday.

Pacific Gas and Electric Co. (PG&E) was the most solar-integrated utility in the U.S. last year, followed by Southern California Edison and San Diego Gas & Electric, according to new rankings released last week by the Solar Electric Power Association (SEPA).

Owners of unregulated power generation in the Mid-Atlantic continued to enjoy high profits in 2008, despite the economic downturn, according to a study of financial data released on Monday by the American Public Power Association (APPA).

Obtaining accurate data about the performance of a plant’s heat-recovery steam generator is crucial to ensuring the smooth operation and maintenance of the equipment. Software designed to model and simulate HRSG operations can provide valuable information about corrosion and other operational problems.

Despite being located on the beautiful Hawaiian island of Oahu, the Kalaeloa Cogeneration Plant had trouble in paradise: Large amounts of ash from #6 low-sulfur fuel oil coated the finned tubes of its heat-recovery steam generators (HRSGs). The fouling added an extra $5 million dollars a year to the plant’s fuel bill. By retrofitting the HRSG with new panels and improved fin design, the plant overcame the fouling problems, stopped tube leaks, and cut fuel costs.

Carbon capture and sequestration is very likely to be a key element of any future greenhouse gas legislation. Integrated gasification combined-cycle plants now under design have provisions to separate the CO₂ at elevated pressures. Coal-fired plants have a far more difficult and expensive task — separating and compressing CO₂ from pressures just above atmospheric conditions.

When roving Contributing Editor Mark Axford attended several recent energy conferences, he found the same questions asked at each one about new U.S. generation sources and consumption patterns. Unfortunately, the experts had few good answers to those questions.
