Arizona Public Service seeks to extend Four Corners coal plant to 2038

· Climate · United States

Arizona Public Service told its Resource Planning Advisory Committee it has signed a coal supply contract extension with Navajo Transitional Energy Co. that would keep the Four Corners coal plant running past its previously planned 2031 closure until 2038.

Why it matters：Adding seven years to a large coal plant's life changes western US power supply, coal demand and the utility's decarbonisation timetable.

Key points

  • APS shared the plan at its Resource Planning Advisory Committee meeting.
  • The coal supply contract extension is with Navajo Transitional Energy Co.
  • The plant had been slated to close in 2031; operation would continue to 2038.
