Greg's power outages
Groogle

This page keeps record of the grid power failures we've had in Dereel. It tracks a similar page I kept for Wantadilla.

“Recovery time” is the time I had to spend to recover from the situation. Times are approximate. Since April 2019 we have battery-backed photovoltaic power, so grid outages should not be an issue any more.
