Secretary of the Interior Sally Jewell has announced the approval of three major renewable energy projects including the SolarReserve's 100 MW Quartzsite CSP plant to be built in Arizona.

Besides the Quartzsite project, a 350 MW photovoltaic plant and a 70 MW geothermal plant, both in Nevada have also been approved, “These projects reflect the Obama Administration's commitment to expand responsible domestic energy production on our public lands and diversify our nation's energy portfolio,” Secretary Jewell said. “Today’s approvals will help bolster rural economies by generating good jobs and reliable power and advance our national energy security.”

The planned Quartzsite Concentrated Solar Power plant will use central receiver (tower) technology with molten salt has heat transfer fluid. This is the same technology being deployed in the under construction Crescent Dunes plant. This technology allows the plant to store thermal energy as hot molten salt that may be later turned into electricity after the sunset.

Despite this step ahead in the process, the plant needs a power purchase agreement (PPA) with an utility. Andrew Wang, SolarReserve's Director of Development, has reportedly said that late 2015 would be the earliest the plant could come online if a PPA were secured tomorrow.

SolarReserve, as available at CSP World's map, has more projects in the pipeline. The above mentioned Crescent Dunes is a 110 MW plant being built near Tonopah in Nevada, it will be the first project to come on line. The Rice Solar Energy Project, a 150 MW plant which was approved by California Energy Commission on December, 2010 has secured a PPA with PG&E.Termosolar Alcazar is 50 MW plant approved in Spain. Another planned projects are Saguache Solar Energy Project (200 MW) in Colorado and Crossroads (150 MW) in Arizona.

Since 2009 Interior has approved 25 utility-scale solar facilities, 9 wind farms and 11 geothermal plants, with associated transmission corridors and infrastructure to connect to established power grids. When built, these projects could provide more than 12,500 megawatts of power, or enough electricity to power more than 4.4 million homes, and support an estimated 17,000 construction and operations jobs.

Interior’s Bureau of Land Management (BLM) has identified an additional 15 active renewable energy proposals slated for review this year and next. The BLM identified these projects through a process that emphasizes early consultation and collaboration with its sister agencies at Interior – the Bureau of Indian Affairs, the U.S. Fish and Wildlife Service, and the National Park Service.

“The President has called for America to continue taking bold steps on clean energy,” said the BLM Principal Deputy Director Neil Kornze. “Our smart-from-the-start analysis has helped us do just that, paving the way for responsible development of utility-scale renewable energy projects in the right way and in the right places.”

All three projects underwent extensive environmental review and public comment. The companies agreed to undertake significant mitigation efforts to minimize impacts to wildlife, water, historical, cultural and other resources.

The Quartzsite Solar Project, located in La Paz County, Arizona, about was proposed by Quartzsite Solar Energy, LLC, a subsidiary of Solar Reserve, LLC (Santa Monica, CA). The 100-megawatt project will use concentrating solar “power tower” technology to drive steam turbine generators with heliostats on 1,600 acres of BLM-managed lands.

The Quartzsite Solar Energy Project will employ dry-cooling technology, which requires a fraction of the water needed for wet-cooling. The project is expected to create 438 jobs during peak construction and 47 full-time operations and maintenance jobs. When operational, the facility will generate enough clean power to meet the needs of an estimated 30,000 homes. Click here for a fact sheet on the Quartzsite Solar Project and here for a map.

The Midland Solar Project is a 350-megawatt solar photovoltaic facility. Proposed by Boulder Solar Power, LLC, the project will be built on private lands about 7 miles southwest from Boulder City, Nevada and will cross 76 acres of federal transmission corridor. The project will provide enough electricity to power about 105,000 homes and generate a peak construction workforce of about 350 employees and up to 10 permanent jobs. Boulder Solar Power, LLC worked closely with the BLM, U.S. Fish and Wildlife Service, and Nevada Department of Wildlife to develop monitoring and conservation measures that will avoid, minimize and mitigate potential impacts.

The project’s infrastructure, for example, was minimized to reduce ground disturbance. Less than 6.7 acres of native plant communities, which provide habitat to nesting migratory birds, will be eliminated as a result of the proposed facility. In addition, the project will obtain water from the existing Boulder City Public Works Department main pipeline, so that surface waters will not be diverted from areas of perennial flow or ephemeral washes, or from downstream habitats that depend on that water.

The New York Canyon Geothermal Project and electrical transmission facility will be built on 15,135 acres of land managed by the BLM about 25 miles east of Lovelock, Nevada in Pershing County. TGP Dixie Development Company, LLC, a subsidiary of TerraGen Power, LLC, will build the 70-megawatt project and associated 230-kilovolt electrical line. The project will provide enough electricity to power about 60,000 homes and create an estimated 150 peak construction jobs and 16 full- and part-time operational jobs. The BLM worked closely with its partners and stakeholders to minimize environmental impacts. For example, a Bird and Bat Conservation Strategy was developed to assess the area’s avian wildlife and reduce impacts on these populations. In addition, there are no listed, proposed or candidate threatened or endangered species present in the project area.
