Management Discussion
  • Pinnacle West’s only reportable business segment is our regulated electricity segment, which consists of traditional regulated retail and wholesale electricity businesses (primarily sales supplied under traditional cost-based rate regulation) and related activities and includes electricity generation, transmission and distribution.
  • Our consolidated net income attributable to common shareholders for the year ended December 31, 2020 was $551 million, compared with $538 million for the prior year.  The results reflect an increase of approximately $13 million for the regulated electricity segment primarily due to higher revenue driven by the effects of weather and lower refunds in the current year related to the Tax Act, higher pension and other postretirement non-service credits and higher revenue from customer growth, partially offset by higher income taxes, including lower amortization of excess deferred taxes, higher depreciation and amortization expense, and higher other expenses. Weather had a significant impact on our result of operations due to the hotter than normal weather in 2020 compared to 2019.
  • Operations and maintenance.  Operations and maintenance expenses increased $14 million for the year ended December 31, 2020 compared with the prior-year period primarily because of:
