AEC Senior Researcher Tyler Comings filed testimony in Arizona on the economics of the Four Corners Units 4 and 5. Mr. Comings found that Arizona Public Service (APS) has repeatedly failed to justify continued investment in the units, and that the units should be retired sooner than currently planned.
