The Department of Energy (DOE) on Tuesday offered a $350 million conditional loan guarantee to develop the One Nevada Transmission Line (ON Line), a proposed 500-kV link that will run 235 miles and transmit 600 MW of mostly renewable energy. The project is the first transmission line to receive a federal loan guarantee.

A new $5 billion transmission project proposed by Trans-Elect and sponsored by Google, Good Energies, and Marubeni Corp. seeks to connect 6,000 MW from wind farms installed up to 20 miles off the Mid-Atlantic coast to the national grid.

Constellation Energy last week offered to sell its 50% stake in the UniStar joint venture to partner Électricité de France (EDF) for $1, plus $117 million in reimbursement costs—a price well below market value—in order to further the project and ensure future energy supplies for Maryland.

Nebraska-based Tenaska on Monday said it would sell a portion of interests in five power plants to Japanese energy firms Tyr Energy and Chubu Electric.

Constellation Energy last week rejected a $7.5 billion conditional loan guarantee offer from the U.S. Department of Energy to build a new reactor at its Calvert Cliffs nuclear plant in Maryland with partner Électricité de France (EDF), saying the government’s proposed terms and conditions were “unworkable.”

Norway’s Ministry of Petroleum and Energy last week called for an evaluation of “alternative solutions” to execute a large-scale carbon capture plant whose construction is under way at the Mongstad refinery on the country’s western coast, after “theoretical studies” indicated health and environmental risks related to amine technology.

A federal appeals court on Tuesday reversed a May 2008 jury verdict finding that Cinergy Corp.—which merged with Duke Energy in 2006—violated New Source Review provisions of the Clean Air Act when it performed certain work on its coal-fired boiler units at several of its Indiana facilities without first obtaining a permit. The ruling allows Duke Energy to restart three Indiana coal-fired units that it had been ordered to shut down.

Solar installations in the U.S.—both photovoltaic and concentrating solar power (CSP) installations—grew 114% in 2009, and by the year’s end, they could surpass 1 GW, a new report from the Solar Energy Industries Association (SEIA) says.

The Environmental Protection Agency (EPA) last week proposed requiring the Four Corners Power Plant near Farmington, N.M., to install and operate selective catalytic reduction (SCR) controls on all five of the 2,040-MW coal-fired facility’s units. The measure would cut the plant’s nitrogen oxide (NOx) and particulate matter emissions by nearly 80%, the agency said.

The Environmental Protection Agency (EPA) has issued a notice of violation to Portland Gas and Electric (PGE), alleging that the company’s coal-fired Boardman facility in Oregon violated the Clean Air Act, including New Source Performance Standards and operating permit requirements.
