Failures can cascade across the grid. A software bug in an Ohio utility's computers in 2003 ultimately took out power for 55 million people in several US states and the province of Ontario. https://en.wikipedia.org/wiki/Northeast_blackout_of_2003 https://en.wikipedia.org/wiki/Northeast_blackout_of_2003
If you have sites in multiple grids you're guaranteed that one failure doesn't take down every site.
- generatorguy 6y agoNever heard it was a software bug? Lack of maintenance allowed tree branches to grow under transmission lines which sag the hotter they get and so on a hot summer day with record system loads one transmission line tripping caused a cascading outage. Read the Wikipedia page, sure the system operators in MISO didn’t get some alarms but blaming the whole thing on that is pretty lame. There were multiple causes and not Getting alarms was just one of 10 things that went wrong.
