I live close by in Braddock Heights and also got tired of power outages. I had a 22.5kw standby generator installed this past February...a Generac. Three weeks after it was installed we had the big wind storm which knocked power out for a day and a half. We were quite comfortable when the rest of Braddock was dark.
Was it expensive? Somewhat. Was it worth it? Yes!
Same here. I had a 20kw unit installed just after the derecho. Since then I've only lost power twice for a total of less than an hour. And yes, it's worth it to not have to worry about losing power.
