Solana

Solar power, even at night

The Solana Generating Station, located outside of Gila Bend, harnesses the power of the sun long after it goes down when APS customers need it most. Solana is one of the largest thermal solar plants in the world. This is an innovative technology that uses the heat of the sun to create steam to power a traditional turbine and allows the sun’s energy to be stored and used after dark.

APS committed to buy 100 percent of the power output from Solana for 30 years, providing our customers with clean and reliable energy, while adding to Arizona’s economy. With enough energy to power 70,000 homes, Solana contributes to Arizona’s continuing leadership in solar energy.

FAQs

What makes Solana’s technology different than traditional solar technology?
Solana captures the heat of the sun and focuses it on a pipe containing a fluid capable of high temperatures. This fluid flows to steam boilers, where it heats water to create steam to power two turbines which produce electricity. The fluid can also be used to heat molten salt in large tanks. When the sun goes down, the heat transfer fluid can be heated by the molten salt to create steam to power the turbines at peak energy usage times at night.

How large is the Solana plant?
Solana covers 3 square miles, about the size of 1,452 professional football fields.

What are the economic benefits of the project?

  • 2,000 local construction jobs,
  • 85 high-skilled permanent positions,
  • 100 high-quality jobs to build 900,000 mirrors
  • 11,000 to 15,000 additional related local jobs
  • Over $1 billion impact on the Arizona economy
Does APS own the Solana plant?
No, the plant is owned by Abengoa Solar, but APS customers will receive 100% of the plants energy for the next 30 years, a deal that enabled the plant to be built.
