Some comments claim that those connections have small capacity. (DC-DC interconnects are a lot more expensive than a synchronized grid.)

- fastball 6y agoYep, they do. But that doesn't mean they don't exist or that they're impossible to do. From what I can tell, each DC tie to the Eastern Interconnect is 800MW max, while apparently the normal draw for this time of year on the Texas Interconnect is something like 45GW. So those two interconnects can only provide 3.5% of total power usually being consumed by the grid, which was obviously not nearly enough for this Black Swan event.
- pas 6y agoHow was this a Black Swan event? This happened in 2011 too.
- AviationAtom 6y agoThis event was a fair amount more extreme than 2011
