Diverse other solar-powered electrical vegetation, the new Solana Generating Concentrate keeps the sun's energy active at the back of dreary to commodities electricity for APS clientele crossways Arizona. The three-square-mile facility nearby Gila Bend, Ariz., uses deep-seated solar power (CSP) technology and thermal energy accommodate to hold the sun's heat to engender a feeling of clean, renewable electricity. (Photo: Ad Connection)Solana represents an type official encourage in solar energy production compared to the more-common photovoltaic technology, which desires directive sunlight in course group to commodities electricity. The three-square-mile facility nearby Gila Bend uses deep-seated solar power (CSP) technology and thermal energy accommodate to hold the sun's heat to engender a feeling of clean, renewable electricity.
This technology enables Solana to commodities electricity at whole vigor for up to six hours at the back of end of the day, by means of the rapid sundown hours at the same time as financier request for power usually peaks in Arizona.
"Solana is a huge time pole in solar energy production," assumed Don Brandt, APS Leader and Main Presidency Executive. "Solana delivers type earn to APS clientele by generating power at the same time as the sun isn't bright. It furthermore increases our solar energy portfolio by approaching 50 percent. This provides a grown-up impetus near our intention to connect with Arizona the solar reserves of America."
Solana is one of the major power vegetation of its put together in the world as well as a vigor of 280 megawatts, a lot to give energy for 70,000 Arizona homes - a city the capacity of Yuma. APS is purchasing 100 percent of the output from Solana, which was constructed and is owned by Abengoa Cosmological.
The plant's CSP technology produces electricity by collecting the sun's heat to create bake that turns good enough turbines. The process begins as well as 2,700 parabolic despondent mirrors, which hunt the sun to set its heat on a passage containing a heat exchange lissom. This lissom, a artificial oil, can assail a excitement of 735 degrees Fahrenheit. The heat exchange lissom after that flows to bake boilers, wherever it heats tarn to create bake. The bake drives two 140-megawatt turbines to commodities electricity, far away appreciate a inherited power plant.
The same as separates Solana from other solar power vegetation is the skill to weapon store the heat from the sun up to six hours for electrical production at unhappy. In very to creating bake, the heat exchange lissom is used to heat molten briny in tanks in close proximity to the bake boilers. The thermal energy accommodate system includes six pairs of hot and aloof tanks as well as a vigor of 125,000 metric oodles of briny, and the molten briny is distant at a minimum excitement of 530 degrees Fahrenheit.
In the role of the sun goes pick-me-up, the heat exchange lissom can be fiery by the molten briny to create bake by manipulation it guide the tanks somewhat of the subject of parabolic mirrors.
"Surrounded by Solana's huge thermal heat accommodate vigor, we can position electrical output from the plant far away best quality fortunate than from other solar power sources," assumed Pat Dinkel, APS Decadence Leader of Find Management. "Surrounded by photovoltaic technology, generated electricity desires to be used pure or it's completed. Solana's technology extends the use of solar energy to commodities power whenever our clientele need it maximum, by means of evenings."
Surrounded by the very of Solana, APS apparition attach 750 megawatts of solar power on its system by the end of 2013, a lot to purpose 185,000 Arizona clientele.
APS, Arizona's major and longest-serving electricity effectiveness, serves best quality than 1.1 million clientele in 11 of the state's 15 counties. Surrounded by function in Phoenix, APS is the greatest minion of Surpass West Metropolitan Corp. (NYSE: PNW).
