APS provides electricity to more than one million customers, serving 11 of Arizona’s 15 counties. APS issued a formal solicitation for renewable energy (including wind, solar and biomass) generated from utility scale facilities of between 2MW and 15MW in April 2010.

Mark Schaftlein, CEO of Nacel Energy, said: “Since we announced Snowflake last July, we have made substantial progress. We first obtained three years of meteorological tower data to quantify the wind resource at our location in Navajo County. We then submitted our plan of electrical interconnection to APS and completed additional important engineering work related to wind turbine placement and power collection.

“In preparing our RFP submission, we were assisted by a tier-one wind turbine manufacturer, enabling us to submit a comprehensive and competitive bid.”
