The solar power plant will use concentrating solar power technology coupled with the ability to store energy during non-sunlight hours to better meet the peak demand of Arizona residents.

The solar plant will also include a thermal energy storage system that allows electricity to be produced as required, after the sun has set.

Under the contract, Eaton’s Electrical Sector will provide an Abengoa subsidiary with electrical power distribution assemblies for the project as well as engineering and consulting services.

Solana is expected to begin operation in 2013, that will prevent 475,000 tons of carbon dioxide emissions per year, as compared to a natural gas plant, while supplying utility provider Arizona Public Service with more solar electricity per customer.

Abengoa Solar will sell all of the electricity generated by the plant to APS for its customers.
