Feds ID land in Az for renewable energy projects

237,100 acres eyed for development

WASHINGTON – The Bureau of Land Management has recommended 237,100 acres of public land in Arizona are suitable for renewable energy development, part of an effort to speed up the process for clean-energy companies looking to set up shop in the state.

The agency Friday released a draft environmental impact statement for its Restoration Design Energy Project, recommending a middle course among six alternatives that ranged in size from 43,700 acres to 321,500 acres.

“Arizona has great potential to build a strong renewable energy economy,” Interior Secretary Ken Salazar said in a prepared statement.

The BLM project is unique to Arizona, but supporters said it is being looked at for other parts of the country. A similar effort has been launched across the West by the bureau.

The Arizona report looked for lands that could become Renewable Energy Development Areas (REDA) for solar and wind energy projects. The option recommended Friday identified agency lands that are either within five miles of points of demand – such as cities or towns – or of utility corridors and existing transmission lines that could carry energy to market.

“I am confident this smart planning will pay dividends for the state now and far into the future,” said Salazar’s statement, which noted that Arizona has some of the most significant solar resources in the world.

BLM took a step toward Friday’s announcement earlier last week when it set aside almost 21,000 acres at Agua Caliente from mining claims for the next two years “to protect this area from encumbrances, particularly mining claims, while it is studied as a potential solar energy zone.”

In the recommendation issued Friday, the BLM said 6,770 acres of the Agua Caliente land – 70 miles east of Yuma – could be a solar-energy zone, making it attractive to companies seeking to develop such projects.

The draft environmental impact statement issued Friday opened a three-month public comment period, but the plan was already getting praise Monday from clean-energy industry officials.

Setting aside land for clean energy is good for the state, said Michael Neary, the executive director of the Arizona Solar Energy Industries Association.

“Arizona is a prime location for solar energy,” Neary said, calling the project another step to Arizona becoming a true player in the solar-energy market.

Craig Cox, executive director of the Interwest Energy Alliance, said he was happy to see the government “taking these proactive steps to advance renewable and solar development on public lands.”

Cox, whose alliance represents firms developing renewable energy in Western states, said it’s particularly good that the BLM was looking at “lands are already disturbed,” or previously used for landfills, mines or agriculture.

The project shows solar is a good option for consumers in the West, Cox said.

“It’s important that we’re moving the ball forward,” he said. “It’s beneficial for consumers and the environment as well.”

Environmentalists also backed the BLM plan, which one said will help Arizona fulfill its potential as a solar energy provider.

“We’re obviously excited to see the BLM and Obama administration taking renewable energy development seriously,” said Bret Fanshaw, spokesman for Environment Arizona, “especially in a place where it makes a lot of sense like Arizona, where the sun shines every day.”

Fanshaw said Arizona is behind states like New Jersey, citing a March report by the Solar Energy Industries Association that said New Jersey had 14 percent of the nation’s installed solar capacity in 2010 to Arizona’s 6 percent.

“We have the most potential for solar energy . . . in terms of how intense the sun is out here and how many days the sun shines, and also, Arizona has a lot of land that can be developed,” he said. “There’s a number of ways we can get there.”

Other groups, while generally supportive, declined comment Monday until they have had a chance to study the nearly 1,000-page BLM document more closely.

Nellis Air Force Base

The Bureau of Land Management has identified 237,100 acres of public land in Arizona that might be suitable for large-scale solar power development. The site above is already operating at Nellis Air Force Base in Nevada.

Renewable options

The Bureau of Land Management looked at six options for Renewable Energy Development Areas (REDA) in Arizona and recommended Alternative 6, covering 237,100 acres in the state.

Alternative 1: Maximum REDA

  • Marks 321,500 acres as REDAs
  • Sets the Agua Caliente Solar Energy Zone (SEZ) at 20,600 acres
  • Emphasizes maximizing opportunities.
  • BLM says Alternative 1, “seeks to provide maximum flexibility for locating small- to large-scale projects without consideration of other physical constraints, such as distance to transmission or load.”

Alternative 2: Transmission Line and Utility Corridor REDA

  • Marks 218,600 acres as REDAs
  • Agua Caliente SEZ would be 6,770 acres
  • Focuses on lands near transmission lines.
  • “This alternative seeks to reduce environmental impacts by focusing renewable energy development on lands within reasonable proximity to designated utility corridors and existing or certified transmission lines.”

Alternative 3: Load-Offset REDA

  • Marks 129,800 acres as REDAs
  • Agua Caliente SEZ would be 2,760 acres
  • Focuses on lands near towns and cities, the Central Arizona Project and the Palo Verde Nuclear Generating Station
  • BLM says this plan aims “to reduce disturbance and environmental impacts by keeping energy generation near the point of demand.”

Alternative 4: Water Conservation and Protection REDA

  • Marks 321,500 acres as REDAs.
  • Agua Caliente SEZ would be 20,600 acres.
  • Focuses on respecting Arizona water sources.
  • “It focuses on avoiding impacts on sensitive surface watersheds, protecting and maintaining groundwater quality and quantity, and reducing consumptive use of water.”


  • Marks 43,700 acres as REDAs.
  • Agua Caliente would not be an SEZ.
  • Only includes land previously determined “suitable for disposal.”
  • “These lands were identified as suitable for general disposal for a number of reasons, including low resource values, previous disturbance, and isolation from larger blocks of public land, which has made managing them . . . difficult.”

Alternative 6: Collaborative-Based REDA

  • Marks 237,100 acres as REDAs
  • Agua Caliente SEZ would be 6,770 acres.
  • Incorporates concepts from all the plans.
  • This plan “incorporates all of the concepts, issues, and protections from the other five alternatives into a ‘blended’ alternative.”
