Don't worry, it's cheaper to wait until the infrastructure fails, THEN replace it. So you won't have to worry about your rates going up to cover pre-emptive replacements of distribution infrastructure. Nope, it'll be nice and cheap. You *might* even get a free month this winter with 0 kWh of electricity to pay for!
If this doesn't happen now, it will when electric cars go mainstream. A portable generator for your home might not be a bad investment...
