Introduction My house experienced a few power outages in the last few years, worst case lasting about 8 days, but also for shorter periods like 3 to 4 days. We seem to be on a weak part of the grid for some reason, as the local outage map provided by Hydro Ottawa also show a similar disheartening pattern.
