As Arizona’s population and economy continue to grow at unprecedented levels, so does the state’s need for reliable electricity. As a result, we are updating our clean energy goal to an aspirational “carbon-neutral” approach by 2050.

We are committed to providing reliable power to customers at the lowest-cost possible while striving to lower carbon emissions over time. Our aspirational carbon-neutral approach means that, by 2050, for any greenhouse gas emissions still produced by our electricity generation resources, we aim to offset these emissions elsewhere. 

A balanced and diverse energy mix will power Arizona’s remarkable growth and help serve our customers with reliable and cost-effective electricity. Our diverse energy portfolio includes:

  • Clean, carbon-free energy from Palo Verde Generating Station – one of the largest nuclear plants and producers of clean energy in the country
  • Renewable resources, including solar energy paired with battery energy storage
  • Natural gas, which is critical to reliability and an important partner to the large quantity of renewable resources we’re adding to our system 
  • Energy efficiency and demand management programs that help customers reduce energy use

Counting on Palo Verde

Palo Verde Generating Station is one of the nation’s largest clean energy producers. Its continued operation is vital to a carbon-free energy future for Arizona and the region. Palo Verde displaces carbon dioxide emissions equivalent to more than 4 million cars driven for a year.

Increasing Clean Energy Resources

We have more than 3,000 megawatts (MW) of renewable resources in our diverse energy mix, enough to serve 480,000+ Arizona homes. By 2027, APS seeks to add 6,000+ MW of cost-competitive solar and wind energy.

Investing in Energy Storage

Energy storage is a critical component of Arizona’s clean energy future. Energy storage systems capture solar energy when the sun is shining bright for use after sunset to meet customers’ needs.

Using Natural Gas to Support Reliability

Flexible generation resources like natural gas will help us meet our growing demand while we incorporate more renewable power. Natural gas is an important part of a diverse energy mix and a necessary partner to the large quantities of solar and battery energy storage we’re adding to our system.

Partnering with Customers

Our customers play a big role in helping conserve energy. The APS Cool Rewards program is one of the largest smart thermostat programs in the country and helps meet demand on Arizona’s hottest summer days. Through summer 2024, with more than 95,000 customer smart thermostats enrolled, the program conserved approximately 160 MW of power —the equivalent of a small power plant’s production.

Plugging in to Electric Vehicles

As electricity gets cleaner, it makes sense to power more of Arizona with it, especially vehicles. This also supports affordable rates and efficient use of renewable energy. Let’s make Arizona a great place to drive electric.
