My clients are doing math they didn't used to do. How long can operations run without grid power? What's the cost of an 8-hour outage versus a 48-hour one? They're asking because the numbers have changed. Average outage duration per customer has doubled over the past decade — 219 minutes to
443 — while the number of interruptions rose only 13%. Longer failures, not more of them.
Utilities can see the failures coming. They just can't dig out fast enough once they hit.
This is what happens when grid infrastructure designed for predictable seasonal demand gets hit with weather events that don't follow the old calendar. Heat waves bleeding into October. Spring maintenance windows colliding with July-level demand in May. The grid was built around assumptions that no longer hold.
NERC's latest reliability assessment puts five of its 15 regions at high risk of not being able to meet demand by 2029. Those five regions cover more than half of US peak demand. PJM, MISO, and ERCOT are on that list. These aren't edge cases. They're the backbone of American power delivery.
Backup generation. On-site storage. Load flexibility. Things that used to be nice-to-haves are showing up in capital plans. When your grid's reliability numbers have been moving in one direction for ten straight years, you plan accordingly.
The policy response so far has largely focused on adding supply. Keeping coal plants running longer. That approach doesn't address the recovery problem, the weather problem, or the demand side, where industrial loads and data centers are adding pressure the current system wasn't designed to absorb.
Adding capacity keeps the lights on during peak hours. Resilience is what determines how fast they come back on after a storm. Right now, is the industry funding one and neglecting the other?
What are your thoughts?

As if hurricanes, tornadoes and wildfires weren’t bad enough, they’re often followed by power failures, nature’s way of kicking you when you’re already on the floor. Oh, you lost your roof? Well, now your ice cream’s all melted too.
