Tessera solar plant injunction granted

Imperial Valley Solar Injunction pauses a 709-megawatt, fast-tracked utility-scale project amid federal ruling, tribal consultation requirements, environmental review, and historic site concerns, signaling broader roadblocks for renewable energy development across the Southwest.

A federal judge granted the Quechan Indian Tribe's request to temporarily halt work on a giant solar plant under development by NTR's Tessera Solar.

The move represents something of a roadblock for efforts to bring more solar power to the U.S. and will likely bolster the position of various groups engaged in green-versus-green conflicts over large solar developments around the Southwest.

While fostering renewable energy has become an important federal and state goal, proposed plants are meeting increasing resistance from groups who believe the plants will do irreparable harm to threatened or endangered plants and animals, such as desert tortoises in fragile habitats, and in this case historic areas, even as some cases are tossed out by California courts during review.

United States District Judge Larry Burns ruled that the federal government failed to adequately consult the tribe before approving the planned solar plant, which is slated for tribal lands in the Imperial Valley, near California's border with Mexico. Extensive consultation on the project is required by law.

The 709-megawatt plant, enough to power at least 140,000 homes, is part of a group of fast-tracked solar projects that were slated for review by year-end.

In part, that deadline was designed to ensure the plants would qualify for a stimulus grant that was slated to expire December 31. But now it seems likely that Congress will extend the grant program by another year.

Deadlines notwithstanding, "government agencies are not free to glide over requirements imposed by Congressionally-approved statutes and duly adopted regulations," Judge Burns wrote in his order.

He further noted that the Department of the Interior, the key defendant in the tribe's suit, helped draft the requirements at issue. Congress and the DOI "could have made these consulting requirements less stringent, but they didn't," he wrote.

Burial areas and other significant landmarks are scattered across the proposed plant's site.

To some extent, the lawsuit is moot. The development of the Imperial Valley plant, plus Tessera's 664 megawatt Calico solar plant in California, are on hold, a Tessera spokeswoman told Reuters. The company is looking for ways to finance the plants, which would each cost around $2 billion to build.

Parent company NTR told investors it had written down the value of its solar-development business by 96 million euros US $127 million.

The Quechan tribe must email a proposed order temporarily enjoining the project immediately.

Spokespeople at the Interior Department's Bureau of Land Management and a spokeswoman at Tessera whose project was put on hold earlier this year didn't immediately respond to requests for comment. Quechan tribal representatives couldn't be reached.

Several other planned solar plants are running into green-versus-green battles with various parties. A group including the Audubon Society is suing to block a plant under development by Solargen in central California's Panoche Valley.

First Solar's Topaz plant, which the company hopes to start building next year, has drawn ire from environmental groups partly because it is slated for a central California area home to endangered San Joaquin kit foxes. The San Luis Obispo county planning commission is considering the project in March.

SunPower's proposed California Valley Solar Ranch, also slated for construction next year, has alarmed environmentalists due to its location in a habitat for endangered giant kangaroo rats. San Luis Obispo County's planning commission will consider the plant in January.
