Living 45 km North of Chiang Mai, we have almost daily short cut-outs and over the year at least 5-10 longer ones of a few hours each, depending on the strength of the rainy season and the root system of trees lining the roads. We are all setup for it, with UPS's for all sensitive electronics, emergency lights and a hard-wired 5 kW generator with an automatic transfer switch. We only turn it on if the power is out for more than 30 minutes (fuel is expensive) and it doesn't have to work very hard, PEA are normally fairly quick reparing the damage even at night. There are 2 food processing factories nearby that are dependent on uninterupted power supply, so PEA have become a bit more responsive since they started operating. Occaisionally we still get a whopper of a black-out that lasts more than 12 hours. A few years back we were without power for almost 2 full days, when a truck driver crashed into a road-side electricity pillar, which subsequently dragged down another 5. It is just the way it is where we live, our side of the road, tends to have more power outages than the neighbours on the opposite side of the road. Always has been. Part of the charm of living in Thailand...
