APS Uses 'Growth Pays for Growth' Model to Develop New Natural Gas Plant
MWN-AI** Summary
Arizona Public Service (APS) has announced a strategic initiative to develop the Desert Sun Power Plant, a modern natural gas facility located near Gila Bend, aimed at enhancing the state's energy supply by adding up to 2,000 megawatts (MW). This ambitious project is designed to accommodate Arizona’s rapidly growing energy demands, particularly from extra-large energy consumers such as data centers.
The project will unfold in two phases. The first phase focuses on strengthening support for current customers through a competitive procurement process, while the second phase introduces an innovative subscription model specifically for extra-large customers. This "growth pays for growth" approach ensures that the costs associated with the new facility are not transferred to residential or small business customers. Instead, the extra-large users will engage in long-term contracts that cover capital expenses, thus mitigating financial impacts on existing customers.
APS executive Jacob Tetlow emphasized the significance of additional natural gas generation in meeting both existing demands and unprecedented requests for energy capacity. By having larger customers fund part of the infrastructure, APS aims to maintain affordability for all users while bolstering the state's energy grid reliability.
The construction of Desert Sun is expected to yield multiple benefits, including job creation, increased economic activity through local collaborations, and enhanced tax revenues.

Thoughtful plan shelters existing customers from paying for data centers, extra-large users
Arizona Public Service (APS) announced plans today to develop a site west of Gila Bend, Ariz., capable of adding up to 2,000 megawatts (MW) of reliable, flexible generation to the state’s energy portfolio. The Desert Sun Power Plant will be a state-of-the-art natural gas facility designed to meet Arizona’s rapidly growing needs, support unprecedented demand from extra-large energy users and enhance integration of renewable energy resources – all while protecting affordability for residential and small business customers.
This two-phase project will support current customer growth through our competitive procurement process in Phase 1 and enable new extra-large customer investments via an innovative subscription model in Phase 2.
“Arizona’s energy needs are growing faster than at any time in our history,” said Jacob Tetlow , APS Executive Vice President and Chief Operating Officer. “Additional natural gas generation is essential to support our existing customers and to begin addressing unprecedented requests from extra-large energy users, such as data centers. By pursuing a ‘growth pays for growth’ strategy, this project protects customers while supporting data centers needed for the U.S. to compete globally.”
The proposed subscription model ensures that Phase 2 would be paid for by the extra-large customers who would use it – not by existing residential or business customers. Extra-large users would sign long-term contracts covering the capital costs and assuming development risks.
How residential and small business customers benefit from this plan
By having extra-large energy users fund a portion of the plant’s capacity through long-term subscription agreements, APS can accelerate infrastructure development without shifting costs to existing customers.
This approach:
- Helps protect and maintain fair prices for all customers.
- Safeguards reliable service around-the-clock, even when energy use is highest.
- Strengthens Arizona’s energy grid and transmission infrastructure.
- Supports a balanced energy portfolio that includes nuclear, solar, wind, battery storage, natural gas and coal.
“Phase 1 will support all customers, helping to meet spikes in demand – such as those on hot summer afternoons – and keeping electricity flowing when renewable power from solar and wind isn’t available,” Tetlow said. “Phase 2 ensures that as Arizona continues to grow, we are relying on innovative solutions to help protect existing customers from the costs associated with expansion. Partnering with our extra-high load customers to maintain cost fairness is a part of our plan.”
Why a balanced energy mix is important
APS’s balanced energy portfolio is designed to ensure strong reliability and affordability for customers. By 2028, APS plans to add nearly 7,300 MW of new resources to support our state’s rapid growth and maintain service during high-demand conditions. Natural gas continues to play a vital role in providing flexibility and ensuring consistent power around the clock.
“Natural gas is an important partner to the large quantity of renewable resources we’re adding to our portfolio and provides flexible, on-demand energy to ensure reliability for customers, especially on our hottest summer days,” Tetlow said.
Nuclear energy and coal add important base-load components that make the system resilient.
Energy grid projects benefit Arizona’s workers and future
“Natural gas generation is a critical component of a reliable and affordable grid,” said Representative Gail Griffin, Chairwoman of the Arizona House of Representatives Natural Resources, Energy and Water Committee. “I applaud APS for its investment in Desert Sun Power Plant which will provide firm, dispatchable energy to support quality service for existing and future customers in Arizona.”
“The strength and reliability of Arizona’s energy grid serves as a competitive advantage in the global competition for 21st century jobs and economic development,” said Christine Mackay, Greater Phoenix Economic Council (GPEC) President and CEO. “APS’s Desert Sun natural gas facility will play an important role in supporting our state’s growth and help ensure Arizona remains an attractive destination for leading businesses, advanced manufacturers and cutting-edge start-ups to invest in.”
“Reliable energy infrastructure is the foundation of a prosperous economy,” said David Martin, President of the Arizona Chapter of the Associated General Contractors. “APS’s investment in Desert Sun will not only ensure Arizona has a strong power supply, but it will also support good paying contractor jobs for skilled men and women in our community.”
Economic and community impact
The Desert Sun Power Plant is expected to be a significant driver of economic growth in Arizona:
- Job creation : Hundreds of construction jobs along with a smaller number of long-term operational positions.
- Business partnerships : Collaboration with local suppliers, contractors and service providers.
