Pinnacle West supplies electricity to Arizona — a state where air conditioning runs around the clock in summer.
Profit is set by the rate base and the allowed return rather than by the volume of energy sold. The region's peculiarity is a sharp summer peak: the system must withstand several weeks of extreme heat, and capacity is built for that maximum rather than for average demand.
The state is gaining population and manufacturing — from chip plants to data centres — and that is a rare case where a utility's territory genuinely grows. A nuclear plant provides round-the-clock carbon-free output whose value has risen. Risks: decisions by a state commission historically strict on tariff increases, borrowing costs and the heat. A dividend is paid.
