APS plans to extend coal use to 2038 as demand doubles by 2041

· Energy · United States

Arizona Public Service expects peak demand to grow about 3.4% annually over the next 15 years, driven by industry and data centers, and expects its sales to double by 2041, according to an integrated resource plan filed with regulators. To meet that load, the utility plans to extend coal use to 2038. The filing illustrates how surging data center and industrial demand is pushing utilities to keep existing dispatchable generation online longer than previously planned, complicating decarbonization timelines. For the power sector, APS's plan is a concrete example of the tension between rapid load growth and emission-reduction goals, and it signals that coal retirement schedules across the US may keep slipping as utilities secure supply.

Why it matters：Utilities stretching coal life to meet data center load shows how the AI power boom can slow decarbonization, a dynamic likely to repeat across fast-growing US grids.

Key points

  • APS expects peak demand growth of about 3.4% annually over 15 years.
  • The utility expects sales to double by 2041.
  • It plans to extend coal use to 2038.
