Yeah : 7,7 square kilometers.
And "Arizona Public Service (APS), the largest utility in Arizona, will purchase all of the electricity produced by the solar plant for 30 years through a power purchase agreement with Abengoa.
Solana will generate the clean energy equivalent to that needed to power 70,000 households and will prevent about half a million tons of CO2 from being emitted into the atmosphere per year. The construction of Solana led to the creation of more than 2,000 jobs and a national supply chain that spans 165 companies in 29 states.
The total investment of the plant is approximately two billion dollars and during financing, Solana received a federal loan guarantee for $1.45 billion from the United States Department of Energy Federal Loan Guarantee Program. This support made the construction of Solana possible, creating or maintaining thousands of jobs both in the building of the plant as well as those direct and indirect jobs in the supply chain, as well as providing the Southwest with clean, sustainable energy using innovative technology. Abengoa currently has 1,223 MW of concentrating solar power in operation and 430 MW under construction. It is the largest CSP company in the world and one of the few that constructs and operates both solar tower and parabolic trough plants."
