An innovative project that uses algae to mitigate carbon emissions from a coal-fired power plant owned by Arizona Public Service (APS) has received a $70.5 million grant from the Department of Energy (DOE).

Exelon, the largest nuclear generator in the U.S., on Thursday signed a $1.2 billion contract to purchase separative work units (SWUs) from USEC’s American Centrifuge Plant to fuel its reactors starting in 2012.

Nuclenor, the operator of Spain’s oldest nuclear power plant, the 466-MW Santa Maria de Garoña, on Monday appealed a government decision to close the plant in 2013. Nuclenor said it had “solid reasons to support the continued operation of the [plant] until 2019.”

The U.S. Environmental Protection Agency (EPA) on Tuesday proposed to throw out three aspects of the Texas clean air permitting program because they do not meet requirements of the federal Clean Air Act. Rejections could include the state’s flexible permit system, which allows power plants, factories, refineries, and other industrial plants to exceed emission limits in certain areas as long as they stay within overall limits.

Dominion Virginia Power said last week that a state air permit relating to mercury emissions for its Virginia City Hybrid Energy Center had been amended, and that the permit was now compliant with an order from the Richmond Circuit Court.

Japanese electronics company Toshiba Corp. could reportedly bid for French state-owned AREVA’s lucrative transmission and distribution (T&D) business. Toshiba, which acquired U.S. nuclear reactor maker Westinghouse Electric Co. in 2006, will likely enter a $5 billion bid, vying against a Chinese sovereign fund and other companies.

Last week saw several important developments concerning coal plants in Germany, Michigan, and Canada.

Two companies have announced setbacks to demonstration projects seeking to develop and commercialize enhanced geothermal systems (EGS) technology. California-based AltaRock Energy shelved a project for which it had secured $36 million from the U.S Energy Department and had the backing of several large venture capital firms, citing “geologic anomalies.” Geodynamics Ltd., meanwhile, encountered a new set of technical difficulties and is reevaluating a 1-MW pilot project in the Australian outback.

The Nuclear Regulatory Commission (NRC) last week issued an Early Site Permit (ESP) and Limited Work Authorization (LWA) to Southern Nuclear Operating Co. for its two proposed Plant Vogtle units in Waynesboro, Ga. The ESP, valid for 20 years, is the fourth issued by federal regulators—but the first based on a specific technology, the Westinghouse AP1000.

The U.S. Energy and Treasury Departments on Tuesday announced stimulus fund awards worth $502 million to energy companies to spur investments in renewable projects and provide “cash assistance” in lieu of earned federal tax credits.
