I don’t quite understand how your analysis fits together, but notes on two pieces:
Assuming that “>3 day outage” = a MED, then we can do a little algebra.
“MED” is “Major Event Day” (definition, context). My stats aren’t that great, but I think what they’re doing is assuming a log normal distribution of outages and then counting any day that’s 2.5 standard deviations worse than average as a “Major Event Day”. So roughly two days a year (0.6% of days) should count as MEDs. What this means is that if you have a very reliable power company you will have a lower threshold for declaring an MED than someone with a less reliable one.
3 days of diesel fuel storage … the City can probably get fuel easier than normal people.
My interpretation is that they will be able to get their generator tanks refilled within three days even in most emergencies. This does not guarantee that the blackout has ended, though.
