Arizona solar plant achieves six hours after sun goes down October 11, by Nancy Owano, Phys. Abengoa said Wednesday that the facility, about 70 miles southwest of Phoenix, can store the sun's power for six hours via thermal energy.
The three -square-mile facility near Gila Bend uses concentrated solar power CSP technology to collect the sun's heat. Thermal energy storage is Solana's distinctive feature. At megawatts, Solana is one of the largest plants using parabolic mirrors.
Its 2, parabolic trough mirrors follow the sun to focus heat on a pipe containing a heat transfer fluid, which is a synthetic oil. The heat transfer fluid flows to steam boilers, where it heats water to create steam. The steam drives megawatt turbines to produce electricity.
Solana is one of the largest power plants of its kind in the world. Beyond size, what makes Solana special as a solar power plant is the ability to store the heat from the sun for electrical production at night, using substantial thermal storage to keep the juice flowing for hours after sundown.
In a report on the Arizona plant by IEEE Spectrum, the point was made that proving that this storage tech can work is a huge step for the solar industry. Intermittency, said the report, is still among the most common complaints about industrial-scale renewable energy.
According to Abengoa, "Solana's thermal storage system, without the use of the solar field, can produce clean energy for six hours at maximum power.
Abendgoa added that "Dispatchability also eliminates intermittency issues that other renewables, such as wind and photovoltaics, contend with, providing stability to the grid and thus increasing the value of the energy generated by CSP. A power purchase agreement with Arizona's biggest electricity utility, Arizona Public Service, is in place covering the full solar plant's output for its customers.
Electricity generated by the plant at its peak would power around 70, homes. With the addition of Solana, APS will have megawatts of solar power on its system by the end of the year, enough to serveArizona customers.Integrated Resource Plan.
