Key findings
- Resilience spending only reduces outage duration where capital plans actually fund transformer replacement.
- Tier 1 neighborhoods saw a 51% reduction in mean outage duration over 5 years; Tier 3 saw an 11% increase.
- Heat-vulnerability funding is flat in the current capital plan despite the trend.
- Restoration timelines matter more than outage frequency for heat-exposed residents.
Extreme weather coverage often isolates the dramatic event from the slower infrastructure decisions that determine who is exposed and for how long.
This analysis reviews grid maintenance schedules, transformer replacement timelines, and heat-resilience investments that affect outage risk across neighborhoods.
The point is not to minimize urgency. It is to place urgency where readers and policymakers can act on it.
Resilience spending is meaningful only if it changes outage duration.
Readers should be skeptical of resilience claims that are not tied to restoration timelines, transformer replacement rates, or neighborhood-level exposure. The analysis focuses on those operational measures rather than broad promises.
