shaping the future with clean energy
​​​Your energy is being generated in increasingly clean ways. The Palo Verde Nuclear Generating Station is already the largest source of carbon-free electricity in the nation. We are also transitioning from older coal units to more efficient natural-gas plants. More than two-thirds of the water we use to generate energy comes from reclaimed water sources. Moving forward, we will meet growing energy needs with zero- to low-emission resources to create a sustainable future for all of Arizona.

​next is changing how we generate arizona's energy
APS and its customers are committed to a future where Arizona’s energy is increasingly cleaner. The projected growth of renewable energy, combined with other environmentally friendly efforts, is predicted to make the overall APS energy mix cleaner and more efficient.
We anticipate by 2029:
  • 2x the amount of renewable energy
  • 3x as much rooftop solar generation
  • 3x as much savings from energy-efficiency measures
  • 14% less carbon dioxide emissions per megawatt-hour of electricity generated
  • 24% less water usage per megawatt-hour of electricity generated

driving arizona's solar leadership
Since 1954, we’ve advanced solar energy throughout the state. Our efforts continue today with programs like APS Solar Partner, an innovative study that brings rooftop solar to customers and supports the long-term growth of solar energy. We’ve also helped more than 300 schools go solar and introduced solar curriculum into the classroom. Today, we generate more solar energy than any utility outside California because we know solar has an integral role in Arizona’s energy future. Learn more about our committment to Arizona's solar leadership.

biogas - landfill

It’s hard to imagine that waste could provide a clean source of energy, but it’s a reality at landfills in Glendale and Surprise. When organic materials break down, they produce methane gas, which is used to fuel large combustion engines that generate power. We purchase nearly all the clean energy generated at these landfills and efficiently distribute it to customers across the state.

four corners

The recent closure of three coal-fired units at the Four Corners Power Plant, which we operate, will make our overall energy mix cleaner and more efficient for generations to come. Ending operation of the older units 1 – 3 will dramatically reduce our carbon footprint in the Four Corners region, while continuing operation of units 4 and 5 will keep high-quality jobs in the Navajo Nation and Farmington areas.

The transaction will save our customers nearly $500 million over the next lowest cost alternative considered—combined cycle, natural gas fired generation.
We anticipate that by 2029, our portfolio will produce 14% less carbon dioxide and use 24% less water per megawatt-hour of electricity generated than today, drastically reducing energy’s environmental impact in Arizona.

ocotillo modernization

The proposed modernization of Ocotillo Power Plant in Tempe will create a cleaner-running, more-efficient plant that helps us meet growing customer demand in the metro Phoenix area. Five new natural gas combustion turbines will decrease the plant's overall water usage and emission rates, reduce the plant’s visibility from surrounding neighborhoods, and decrease noise conditions – all while maintaining the reliability our customers require.


cleaner, greener, quieter fleet
It’s our job to stay ahead of Arizona’s changing energy needs. That’s why we’ve implemented a new standard of replacing our fleet vehicles with electric alternatives where economically feasible. We’re committed to creating a bright energy future. Learn more about our fleet of vehicles here.
