More recently, in Houston, TX, my home had power for only 18 days out of 60. It wasn't always like that, but nowadays, the light company seems to rely on storm damage to show them where their infrastructure is weak and needs replacing rather than routine or preventive maintenance.
Meanwhile, up here in Udon, I put up with about 10 years of low voltage in the evenings. I was on the cusp of buying and installing an AVR when the light company completed their grid upgrades, and it's been rock-solid for over three years now.
YMMV
