“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: 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: 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?”

Reed: Federal backstop authority for transmission line siting has never been used
“Transmission has always been permitted exclusively at the state level. There's been some very, very narrow federal authority established for it, but it's kind of this multi-step, elaborate process. There's a study, and then someone else has to review it, and t…”
