While strong growth in our number of customers is projected long term, APS customers also continue to use more electricity per customer. To meet this added demand, we will invest $10 billion in energy resources over the next decade.  We continue to secure new generation and site new power lines, improve reliability and expand customer choice. We’re also holding down costs and increasing productivity, planning for the future and seeking fair returns for investors for one clear, indispensable purpose—to create a sustainable energy future for Arizona. Reliable and affordable electric power is the key energy cornerstone for a dynamic modern economy.  New investments now can lower long–run costs, ensure high levels of service quality, facilitate competitive markets and promote environmental goals.

The economic and business success of our family of companies is linked to the economic success and sustainability of the communities that we serve. That is why Pinnacle West is so active in the community. We have a commitment to bettering the state's economic and social vitality by being active in economic development, through community and business leadership, volunteerism, education, environmental stewardship and charitable giving. 

Pinnacle West has a tremendous economic impact on the communities we serve, including:

• Our product, electricity, is essential to economic growth and a functional economy. Our customers rely on us to provide efficient and reliable electrical service so that they can live, work and grow their businesses
• Pinnacle West is a major employer in Arizona, and one of a relatively few S&P 500 companies with headquarters in Arizona
• APS is essentially one of the largest construction companies in Arizona due to the extensive construction of new substations, distribution and transmission lines, power plants and other infrastructure necessary to both maintain our system and to expand our system to meet the rapid growth of our customers.  Last year, we kept pace with Arizona’s growth by investing $900 million in infrastructure, and we expect that amount to rise and remain around $1 billion annually.
• Affiliate SunCor is a major developer in commercial and residential projects
• Pinnacle West's economic development efforts are a major contributor to economic growth in Arizona. We are somewhat unique in that our economic development efforts extend to all areas of the state, including rural areas, rather than just focusing in on the major metropolitan areas
• Pinnacle West's Supplier Diversity Program has provided a significant benefit to the development of a diverse supplier network in Arizona
• Our extensive network of power plants, transmission and distribution lines, offices and support facilities provides a great deal of property tax dollars to the areas we are located. For example, the Palo Verde Nuclear Generating Station is the largest single commercial taxpayer in Arizona

In this report, we also provide financial details on issues such as spending on minority- and women-owned businesses, and charitable donations, and have a detailed discussion on climate change which may have future economic impacts.
