The remaining replacements will take place over a seven-year agenda. For this Unit 1 replacement, the Framatome team leveraged 3-D modeling for the component and piping design, as well as precision measurements.

The Palo Verde plant is comprised of three pressuirzed water reactors each with a gross capacity to produce 1,400 megawatts of electricity. The plant produces about 70 percent of Arizona's carbon-emissions-free electricity. Overall, the plant meets more than a quarter of the state's demand for electricity, supplying power to 4 million people across four different states.
