Outage risk in Arizona

Central and southern Arizona (Phoenix, Tucson) see significant summer grid strain from extreme heat and monsoon-storm outages across the APS, SRP, and TEP service territories. Northern Arizona (Flagstaff) has a very different profile -- winter storm and wildfire-driven outage risk at elevation, closer to a mountain-West climate than the desert valleys to the south.
