“Undergrounding AC is actually incredibly difficult. You can only go 40 to a hundred miles, kind of depending on how much, how you design the system and how you want to control it, because the ground itself, like, actually creates Stability issues for moving AC power.”

Reed: External Transmission Can Support Under 1% of ERCOT Load
“And then ERCOT is incredibly isolated. So there's one or two ERCOT has some minimal Back to back and some minimal AC at sort of very low voltage, but incredibly isolated. I think less than one percent of their load or something is available via transmission. C…”
Reed: Non-ERCOT Texas avoided prolonged blackouts through grid interconnections
“And even the parts of Texas that were not run by ERCOT, especially, right, were experiencing this extreme weather, but did not have this massive multi-day blackout problem. Because they had so much more power available and were able to share it.”
Reed: Decarbonizing the grid requires at least doubling transmission capacity
“The scale that we need to decarbonize the electricity system means we need to get twice as much transmission capacity or more. In the coming decades.”
Reed: Underground HVDC may cost only 1x to 2x of overhead lines
“There's some estimates out there that you might actually be closer to parity as opposed to the sort of five to 10 X that's normally cited. It could be closer to one to two X if you think about power over distance. So mile by mile you're more expensive, but gig…”
Reed: Reconductoring with composite core lines can double grid capacity
“It's a lot faster to add capacity to the grid by just taking out old steel reinforced lines and replacing them with composite reinforced lines. You can get multiple times the capacity. I think two X is the number that I hear most hear quoted the most.”
Reed: Utility regulations incentivize building new transmission over maximizing existing systems
“You can get a rate of return on new capital expenditures, which is new transmission lines, but you don't get that same benefit as an investor-owned utility for just maximizing what you already have in your system, right? In most places, right?”
