Support Activities
Firm Infrastructure
Pinnacle West's firm infrastructure is built to manage more than $20 billion in assets and support APS's service to about 1.4 million Arizona customers in 2025. It centralizes regulatory, legal, and treasury work to meet Arizona Corporation Commission rules and fund multiyear capital plans. That discipline also helps protect APS's investment-grade credit profile, which lowers financing risk for large utility builds.
Human Resource Management
Pinnacle West manages about 5,800 employees, with human resources centered on scarce engineering and nuclear skills needed at Palo Verde, one of the U.S.'s largest nuclear plants. In 2025, it kept labor stability through safety training and bargaining with the International Brotherhood of Electrical Workers, helping support reliable service across 35,000 miles of transmission and distribution lines. As the workforce ages, knowledge-transfer programs are key to preserving outage response, plant reliability, and long-run grid performance.
Technology Development
Pinnacle West, through Arizona Public Service, uses technology development to modernize the grid for more than 1.4 million customers. In 2025, it kept pushing grid upgrades, smart meters, and utility-scale battery storage so APS can handle Arizona's sharp summer peaks and balance rising solar output. These tools support predictive maintenance, faster outage response, and real-time load control across the Western Interconnection.
Procurement
Pinnacle West's procurement team buys nuclear fuel, natural gas, high-voltage gear, and solar parts for APS, which serves nearly 1.4 million retail customers. Long-term contracts help steady fuel and materials costs, which matters when commodity prices swing. Its scale also helps win better terms on grid equipment and clean-energy inputs for the 2025 transition plan.
Pinnacle West's Support Engine Powers 1.4M Customers
Pinnacle West's support activities in 2025 keep APS running for about 1.4 million Arizona customers, with firm infrastructure, HR, technology, and procurement tied to a more than $20 billion asset base. These functions help fund regulation, retain scarce utility talent, modernize the grid, and control fuel and equipment costs. That support underpins reliability across 35,000 miles of lines.

Primary Activities
Inbound Logistics
Pinnacle West's Arizona Public Service served about 1.4 million customers in fiscal 2025, so inbound logistics must keep fuel and power flows tight. APS coordinates uranium for Palo Verde, a 3,937 MW nuclear plant, plus natural gas for peaking units and spot market buys when Arizona demand spikes. That supply mix helps cover the extreme Southwest summer load without stranding generation.
Operations
Pinnacle West's operations center on APS's diverse generation mix, led by the 3,937-MW Palo Verde plant, the largest carbon-free power producer in the U.S. In 2025, Palo Verde kept serving Arizona demand through 24/7 monitoring of cooling systems, reactors, and transmission links. Operational focus stays on high capacity factor and low heat rates, since even small efficiency gains can cut fuel and outage costs.
Outbound Logistics
Outbound logistics at Pinnacle West centers on moving electricity through about 11,000 miles of transmission lines and more than 30,000 miles of distribution lines, linking remote generation to Phoenix-area demand. Load dispatchers use automated control systems to balance flows, protect line capacity, and cut outage risk across a service area of about 35,000 square miles. Smart-grid tools now help reduce line losses and improve delivery efficiency by routing power more precisely in real time.
Marketing and Sales
Pinnacle West earns most of its revenue through Arizona Corporation Commission approved regulated rates for residential, commercial, and industrial customers, so sales is tied more to tariff design than price chasing. Marketing is mostly educational: it pushes energy efficiency rebates, demand-response programs, and time-of-use plans that shift load away from peak hours. Strategic account managers also work one-on-one with large commercial clients on tailored power solutions that support local growth and keep long term load in the system.
Service
In fiscal 2025, APS served about 1.4 million Arizona customers, so Service is a core value-chain step. Its 24/7 outage response, field crews, and digital portal help restore power fast in extreme heat, when even short outages matter. Customer service also handles billing help, low-income affordability programs, and renewable energy buy-back requests.
Pinnacle West Powers 1.4M Customers with Reliable Regulated Service
Pinnacle West's primary activities in fiscal 2025 centered on APS serving about 1.4 million customers with reliable power from Palo Verde's 3,937 MW nuclear fleet and other generation. Operations and outbound delivery relied on about 11,000 miles of transmission and over 30,000 miles of distribution lines across 35,000 square miles. Sales and service were mostly regulated, with customer programs, outage response, and billing support driving retention.

Frequently Asked Questions
Pinnacle West operates as a regulated monopoly, meaning the Arizona Corporation Commission directly influences its value chain profitability. The commission sets the allowed return on equity, often near 9.5%, which dictates how the company recovers the costs of its $1.5 billion annual capital investments. This oversight ensures that infrastructure expansions remain affordable for the 1.4 million customers while providing the utility with predictable revenue streams for future grid upgrades.
