APS Sustainable Water Strategies and Practices
Speaker: Henry Day, Water Policy and Strategy Consultant, Arizona Public Service Company
Since its inception in 1884, originally as Phoenix Light and Fuel Company, Arizona Public Service Company, the largest electric utility in Arizona, has generated clean, reliable, and affordable energy from nine power plants, now serving 2.7 million Arizonans. APS has long been recognized as a leader in water reuse, as demonstrated by its use of reclaimed water as cooling water for Palo Verde Generating Station, the largest producer of power in the United States for the last 25 years. Recognizing the value of water to power generation in an increasingly water-challenged environment, APS created a Water Resource Management Department in 2009. This department focused primarily on water acquisition, contracts, and agreements in direct support of power plant generation, but also developed water conservation practices and strategies to be employed across Arizona and New Mexico. In 2020, APS took another step forward with creation of the Sustainability Department with a broader mission to direct the company's water planning and policy efforts and engage with other stakeholders to ensure Arizona's water supplies are preserved for future generations. In 2020, APS committed to provide 100% clean, carbon-free electricity by 2050, with 2030 targets of 65% clean energy and 45% of generation from renewable sources. This commitment is associated with reduced water consumption goals and strategies that will be discussed in this presentation.
