Looking Ahead

New APS Plan Addresses Growing Customer Energy Needs

APS filed the 2023 APS Integrated Resource Plan (IRP) at the Arizona Corporation Commission today. It includes strategic years-ahead planning to continue to provide customers a reliable power supply well into the future. The 2023 IRP provides a 15-year outlook on how much electricity APS customers will need and what investments are necessary to address those needs with around-the-clock energy amid unprecedented growth of people and businesses moving to Arizona.

APS worked with its Resource Planning Advisory Council (RPAC), a stakeholder group that includes local consumer advocates, university researchers, resource developers and environmental and public interest organizations. This group participated in meetings and workshops over the last year to incorporate transparency, diverse perspectives and extensive dialogue into the integrated resource planning process.

“Our state is growing rapidly and when we think about how important reliable power is for customers, and especially considering the unique challenges Arizona’s summers bring, it’s critical we plan years in advance,” said Jacob Tetlow, APS Executive Vice President of Operations. “Our team has worked collaboratively with a diverse group of stakeholders to develop the 2023 IRP and find pathways to continue to provide top-tier reliability, while maintaining affordable rates, for our customers well into the future.”

How much power will APS customers need in the future?

APS resource planners used extensive modeling and data analysis to develop forecast projections for energy demand. For perspective, today, APS customers benefit from almost 9,400 megawatts (MW) of available electricity, an amount the energy company reached over the span of nearly 140 years since it began serving customers. Thanks to previous planning, that supply was available and served around-the-clock use of air conditioning by homes and businesses during the record-breaking 2023 summer heat wave.

Looking ahead, the modeling shows:

• By the end of 2027, APS customers will need about 11,350 MW, an amount equivalent to what it takes to serve about 1.8 million Arizona homes.

• By 2031, APS customers will require a total of more than 13,000 MW and peak demand will grow by about 40%. Peak demand is a period of time when customer energy use is at its highest.

• By 2038, APS customers will need more than 14,820 MW of electricity.
