Solana: The world’s largest solar plant
Location: : Gila Bend, near Phoenix (Arizona).
Type of project : 280 MWe, CPS Trough Plant with storage.
Abengoa Solar has signed an agreement with Arizona Public Service (APS), the largest electric company in Arizona, to build and operate what will be the largest solar power plant in the world.
Recently, the White House announced that DOE Department of Energy has offered a conditional commitment for a $1.45 billion loan guarantee to Abengoa Solar, Inc. The loan will support the construction and start-up of Solana.
The plant will be installed about 70 miles southwest of Phoenix, near Gila Bend. Solana, with 250 MW nets of power output capacity, is based on parabolic trough technology and thermal storage using molten salts. When operation starts up, the plant will have the capacity to supply clean power to 70,000 homes and will eliminate around 475,000 tons of CO 2.
The building of Solana will also create between 1,600-1,700 new construction jobs, and operation of the plant will add another 85 permanent jobs. These construction and operating jobs will create a few thousand additional indirect jobs.

Solana will operate like Solnova1, with the addition of storage capacity as shown in the diagram below.
This thermal storage allows the system to send power to the grid even when the sky is overcast and allows Solana to generate elecricity even after the sun goes down.
