Abstract Wildfires and post-fire debris flows (PFDFs) threaten California infrastructure are evolving with climate change. There is significant focus on the threat of utility-caused wildfires because electric power equipment has triggered leading to major damage. California’s ambitious targets rely electrification transport industry. As state modernizes its electricity system support increased demand, it must consider future hazards. To date, there no rigorous characterization intersection fire threat, PFDFs, electrical infrastructure. We estimate wildfire PFDF transmission lines, substations, generators in assess vulnerability utilities by intersecting current using two global models representative concentration pathways. find clean, dispatchable (e.g. hydroelectric nuclear) small, publicly-owned most vulnerable. Increasing threats will require additional resources consideration distribution.

Abstract Several recent widespread temperature extremes across the United States (U.S.) have been associated with power outages, disrupting access to electricity at times that are critical for health and well-being of communities. Building resilience such in our energy infrastructure needs a comprehensive understanding their spatial temporal characteristics. In this study, we systematically quantify frequency, extent, duration, intensity demand six North American Electric Reliability Corporation regions using ERA5 reanalysis data. We show every region has experienced hot or cold affected nearly entire extent events were substantially higher demand, resulting simultaneous stress electric gird. The western U.S. significant increases frequency (123%), (32%), duration (55%) (29%) Texas (132%) extremes. decreased most without substantial changes other Using outage data, coincided outages account between 12%–52% all weather-related past decade depending on region. Importantly, find solar potential is significantly during five regions. Further, wind least three Our findings indicate increased capacity could be leveraged meet extremes, improving reliability systems addition limiting carbon emissions.
