The Dry Lake Wind Power Project in Navajo County is the first and the largest utility-scale wind farm in the U.S. state of Arizona. Starting in 2009, it was constructed in two phases having a total generating capacity of 128.1 megawatts (MW), and is selling the electricity to the Salt River Power District (SRP).

History

Around 2003, rancher Bill Elkins began working with developer John Gaglioti and Northern Arizona University scientists to erect measurement towers on his land to measure wind speeds. He studied the local power grid to determine the feasibility of connecting a wind farm. Navajo County and Iberdrola officials credit Gaglioti and Elkins with attracting the first wind farm to Arizona.[1]

Project details

Phase 1 (34°39′36″N 110°17′03″W) consists of 30 Suzlon 2.1 MW wind turbines, for a total nameplate capacity of 63 MW.[2] Iberdrola Renewables built the wind farm for $100 million. Based on wind measurements before construction began, Iberdrola estimated phase 1 would produce an average of 132,450 MWh annually. Depending on actual performance of phase 1, the company planned to install up to 209 more turbines in future construction phases.[1]

Phase 2 (34°36′22″N 110°10′24″W) consists of 31 additional Suzlon turbines for a combined nameplate capacity of 65.1 MW.[3] The location of phase 2 is about seven miles (11 km) northwest of Snowflake and three miles (5 km) southeast of phase 1.[4]

Environmental effect

According to the USDOE, each 1000 MW of wind power capacity installed in Arizona will save 818 million US gallons (3,100,000 m³) of water per year and eliminate 2.0 million tons of carbon dioxide emissions.[7] Phase 1 of Dry Lake Wind Power Project would then eliminate:

${\displaystyle {\frac {2,000,000{\mbox{ tons}}\times 63{\mbox{ MW}}}{1000{\mbox{ MW}}}}=126,000{\mbox{ tons}}}$

of carbon dioxide, and save:

${\displaystyle {\frac {818,000,000{\mbox{ gallons}}\times 63{\mbox{ MW}}}{1000{\mbox{ MW}}}}=51,534,000{\mbox{ gallons}}}$

of water annually.
