Arizona Public Service Co. (APS) and First Solar have completed the 17 MW Paloma Solar Power Plant, which consists of 275,000 thin-film photovoltaic panels mounted on fixed-tilt steel supports.
Earlier this week, APS also placed the 17 MW Cotton Center Solar Plant in commercial operation – the second AZ Sun facility to come online.
The projects, both located in Gila Bend, are part of APS' AZ Sun Program, which is expected to have 100 MW of utility-scale solar power online in Arizona by 2014. Third-party partners, such as Tempe-based First Solar, develop and construct the AZ Sun facilities, which APS will own and operate upon completion.
The first phase of the AZ Sun Program was approved by the Arizona Corporation Commission (ACC) in 2010. The Hyder Solar Plant in southwestern Arizona is expected to reach commercial operation in the fourth quarter of this year, making it the third AZ Sun facility to be placed in service. Additionally, APS has an application pending before the ACC for another 100 MW phase of the AZ Sun Program.
