Solar Projects


Future & Current Tempe Solar Installations 

On June 12, 2014 Tempe City Council adopted a goal to provide a minimum of 20% of the municipal operations energy from renewable energy sources by the year 2025One of the ways the City plans to increase the use of sustainable, efficient and clean alternative energy in city facilities and operations is through the installation of solar structures on city properties. Read more about these projects below, and feel free to also check out our energy dashboards.

South Water Treatment Plant Solar Installation


Since the South Water Treatment Plant Solar installation went active in March of 2014, it has produced 599,544 kWh of electricity for the property. This number is equal to avoiding 430 tons worth of CO2 emissions; which is equivalent to:

  1. The carbon offset by 366 trees
  2. The emissions given off by 641,512 pounds of coal
  3. Water saved = 239,818 gallons

These numbers accurate as of June 30, 2014

  • The South Water Treatment Plant Solar Installation is projected to supply 1.6 million kilowatt-hours of energy per year to help power the plant’s daily operations.
  • There are over 3,000 panels in this system - supplying 15% of the water plant’s energy needs.
  • Tempe expects to save more than $25,500 in utility costs during the first year, with anticipated savings of $2.3 million over 20 years. The project will reduce the water plant’s carbon emissions by 1,130 metric tons annually, equivalent to removing 235 cars from the road each year.
  • This project was completed through a partnership between the City of Tempe, SRP and Solar City.

Tempe Beach Park APS Solar Installation

Solar Ramada

  • The Tempe Beach Park APS Solar Installation supplies 20,000 kilowatt-hours of energy per year to help power facilities on the south side of the park, including the ball field, park lights and splash playground.
  • APS chose the Tempe site from among numerous statewide applications because of its prominent location. More than 1 million people visit Tempe Beach Park each year for major events and recreational activities.
  • The new installation also provides shade for picnic tables and a gathering area.
  • Interpretive signage explains how the panels turn sunshine into electricity.
  • There are 52 panels and microinverters in the 10 kw system. This provides 13% of the energy needed for the park’s south side facilities.
  • The Tempe Beach Park APS Solar Installation project was funded by the City of Tempe, the Arizona Commerce Authority Energy Office, U.S. Department of Energy and APS.
