Howard: Slow Environmental Reviews Dramatically Harm the Environment
“All these lengthy environmental reviews turn out to be dramatically harmful to the environment because we can't fix the bottlenecks. We can't create the new transmission lines that carry electricity from the, you know, renewable sources and such. It's overwhel…”
Gramlich: Transmission lines completed in 2024 began 10 to 15 years ago
“These were lines that were, like, begun 10 or 15 years ago that just finally got finished.”
Lubershain: GETs deployment is inherently slow due to necessary substation upgrades
“If you're going to change that stretch of transmission line and expect to get higher throughput, you also need to upgrade the substations at both ends. For example, you know, sometimes that might require you to, you know, make other upgrades on the system at t…”
Transmission lines act as direct substitutes for local baseload power generation
“The transmission line itself is a substitution for baseload power, because if you can move more power over more space, you are Reducing the need to have to generate that power on the other end of that congestion. So in that sense, transmission and generation a…”
Permitting new transmission lines is globally harder than building nuclear plants
“It's going to be easier to permit and get a nuclear plant built than it is to get new transmission lines, and that's just historically how it's been, you know, everywhere I've been, whether it's in the US, the UK, Australia. Over in Taiwan Philippines, people …”
LineVision's sensor technology increases transmission line capacity by up to 40 percent
“LineVision has a technology, it's a combination of soft Square and sensors that allows us to increase the capacity of a transmission line by up to 40% or more without having to either reconductor the line or build new lines.”
Wind's cooling effect has the biggest impact on transmission line capacity
“It turns out that it's the cooling effect of wind that actually has the biggest impact on the capacity of the line, and so understanding wind at a really accurate hyperlocal level allows us to understand what that true capacity is”
EMF sensors proved inefficient for monitoring multi-conductor transmission corridors
“You can imagine trying to use EMF sensors to isolate the signal from each of those individual conductors and all the complicated map that goes into it. And long story short, that got really messy really quickly and was not kind of an efficient way to get the i…”
Solomon: Advanced conductors can be deployed in 18 to 36 months
“You can replace the existing transmission conductor with this new advanced conductor in as little as 18 to 36 months with much fewer permitting requirements and things like that.”
Lubbershane: Static transmission constraints hold true only 10% of the time
“They're they may only be holding true and really constraining the amount of power that you can safely move through the line, say, 10% of the time. Most of the time, you could move more power through the line.”
McEntush: Wind power reliability depends on transmission lines
“People often say, like, the wind is always blowing somewhere, but that only matters if you have the transmission lines to move wind from one place to another.”
Jaramillo: Buffering transmission lines with energy storage increases their utilization
“Having storage, you know, the ability to buffer at one end or both ends makes that even more a highly utilized resource.”
Naam: Clean electricity will beat fossil fuels if permitting opens up
“Like, in an open playing field, if it's easier to build pipelines and transmission lines, Clean electricity is going to win.”
Tomlinson: Texas transmission lines cost about $1M per mile
“And it's about a million dollars a mile to run a transmission line in Texas.”
Gramlich: High-capacity transmission buildout has dropped 90% since 2013
“So for the last decade, there really wasn't much, and kind of now it's dried up to a trickle. Like, we're down in the, you know, couple of hundred miles of high capacity, so less than 10% of what we did a decade ago, and that's kind of where we are.”
Gramlich: Transmission bottleneck is caused by cost recovery, not capital shortages
“There's no, there's never been a shortage of investment capital for this business, but there's a shortage of ways to get your money back when you build useful lines.”
Shah: Reconductoring existing lines provides all needed US grid transmission capacity
“You can reconductor all of the existing lines and get all of the existing, All the new transmission capacity that you need. We have reports out of Lawrence Berkeley Laboratory that say that. We have, like, private sector and geo reports, et cetera, that say th…”
Reed: US has 400,000 transmission miles, but only 25% are high-voltage
“So we've got about 400,000, just over 400,000 miles of transmission lines in our, in this country, and most of them are lower voltage, so they're still, like, fairly local in terms of how far they can move power. I think it's two-thirds of them. Actually three…”
Reed: Over one terawatt of US generation is stuck in interconnection queues
“There's more than, I want to say there's more than a terawatt of energy generation in these queues across the United States that aren't able to come online because we don't have the necessary transmission to support them.”
Hamilton: Some transmission developers need tax credits, not permitting reform
“Like, there are some companies that are building transmission lines that don't need permitting reform, that instead actually need an investment tax credit.”
Lacey: Transmission hype outpaces the reality of difficult US construction
“Relative, the hype relative to the reality of building out transmission lines that they don't match up. And I have to, I unfortunately have to be a sell. Even though, you know, I generally support lots more transmission build out in this country. I think it's …”
