Eaton to Provide Solutions for Arizona?s Largest Concentrating Solar Thermal Power Plant

Diversified industrial manufacturer Eaton Corporation (NYSE:ETN) announced an $8.1 million contract to provide electrical power distribution system equipment for Abengoa Solar’s 280 MW Solana Generating Station, which upon completion, will be one of the largest concentrated solar energy plants in the world.

Located 70 miles southwest of Phoenix, the solar thermal plant will use concentrated solar power (CSP) technology coupled with the ability to store energy during non-sunlight hours to better meet the peak demand of Arizona residents. Because Solana, which is Spanish for “sunny place,” will not emit greenhouse gases, it 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 (APS) with more solar electricity per customer than any other utility in the United States.

“Solana is a unique project that will help position Arizona as a leader in alternative energy and overall reduction of carbon dioxide emissions,” said Kevin McLean, senior vice president, Global Marketing, Electrical Sector, Eaton Corporation. “By combining the reliability and efficiency of Eaton’s electrical distribution system with Solana’s highly-innovative technology and energy storage capabilities, the project can serve as a model for other utility providers.”

Under the contract, Eaton’s Electrical Sector will supply an Abengoa subsidiary with electrical power distribution assemblies for the project as well as engineering and consulting services. Eaton is a leader in electrical power distribution and delivers reliable, efficient and safe power distribution products for industrial and commercial applications worldwide.

Solana is expected to begin operation in 2013, and unlike a photovoltaic solar plant, which uses sunlight to produce electricity, the CSP solar trough technology utilizes trackers with high precision parabolic mirrors that follow the sun’s path and concentrate its energy, heating a fluid to over 700 degrees Fahrenheit and using that heat to turn steam turbines. The solar plant will also include a thermal energy storage system that allows electricity to be produced as required, after the sun has set. APS will purchase all of the generated electricity from the plant’s owner, Abengoa Solar, for its customers.

Abengoa is an international company that applies innovative technology solutions for sustainability in the energy and environment sectors, generating energy from the sun, producing biofuels, desalinating sea water and recycling industrial waste.
