Phoenix treatment plant built by SunPower starts operating

The city of Phoenix's Lake Pleasant Water Treatment Plant has started working directly with the sun to help produce the energy needed to operate the plant, which produces 15 billion gallons of tap water each year. A 7.5-megawatt high efficiency solar power system, which was designed and built by SunPower and is the largest such installation on city property, is expected to generate 70 % of the plant's electrical power needs. A total of 22,936 solar panels are being used to save approximately 15M kWh each year, resulting in savings of approximately $4.2M over the next 20 years as compared to conventional electricity.
