I work for electric utility. 500/345/138KV Extra High Voltage. (Transmission System) Takes 5 yrs to journey out but you need them to basically have 7 years to be well versed out their job 2 years as a Journey Level. Been a shortage for a long time but also utilities are not raising staffing levels even if the individuals were available. Also utilities got greedy for a long time with lower pay & ample people. Now the tides have turned & they throw up their hands all helpless. They even at one point was cutting benefits etc. Then supply chain equipment, vehicles all worn out & utilities didn’t act when they should have now a back log that causes more & more issues. I could go on & on. Than all the aging infrastructure they refuse to retire. Now it cost double or triple to replace vs 2014 era.
This was a very interesting article. It made me evaluate the China build out of coal power in a new light:
The coal plants also require a grid connection. So maybe the main goal of the coal plants is the build out of the Chinese grid.
China has, according to reports, been operating a 40MW molten salt test reactor since April 2022.
A molten salt reactor can drop in place to decarbonize a coal plant very quickly.
China is the one country in the world that could, immediately, pull the trigger on a massive build out of Thorium molten salt reactors as soon as they are satisfied that the reactor is safe. And safe by their own standards.
China could completely decarbonize, using the steam equipment and electrical generators, and have the grid connection finished. When they pull the trigger this could be done in 5-10 years.
Maybe they are only building coal plants for the grid connections and generators. Maybe, they are playing the long game...?

Terrible picture at the beginning of this article, the worker is using a climbing belt that has been banned by OSHA for years, and he's not even wearing safety glasses. You should have a modern photo of a worker using the correct PPE.
Another great article. Informative, data-driven concepts, serious and thoughtful, addressing technical issues and offering feasible solutions. Thank you for posting.
Thank You… thank you, thank you, thank you. I am so happy someone called out that absurd nonsense by the Times.
The idea that we should drastically expand the grid and spend over $684 Billion to accommodate a bunch of non-dispatchable, dilute, weather dependent crap is absolutely insane.
One thing you also brought up which I really want to emphasize is that these transmission expansion projects get extreme opposition everywhere they are attempted. I live in New England I have seen this first hand.
We would be infinitely better off reusing the existing infrastructure, building SMRs, and getting this done.
Nuclear will relieve the grid - SMR (small modular reactors) can be built closer to industry and remote locations. Or build reactors closer to cities to cut back on grid dependence.
If you had said that "they" would spend our money (to no good end) like drunken sailors, you would have insulted drunken sailors ... but at least as the joke goes, it is the sailor's money. But you inferred that "they" are batshit crazy. You managed to insult bats, shit, and crazy in one sentence. Hat trick.
Interesting article. The NYT is just spouting more worthless green nightmares pushed by the professional liars in Amory Lovin's RMI. More vaporware that will never get built.
A few points. I assume a gigawatt-mile is the electrical capacity of the lines multiplied by the miles. So a 1 gigawatt line 100 miles long and and 100 gigawatt line 1 mile long have the same capacity-length. Of course, such a metric obscures more than it reveals. Lineman are hard to find, but I would also worry about engineers; high-voltage transmission is a very specialized specialty. Finally, this is just another worthless power play, an attempt to override local control to impose someone's personal vision. It is the California high-speed rail project, gone national and impinging something more important than an alternate form of transportation.
The current US annual consumption is 451 GW average annual power. That is serviced with an installed capacity of 1.1 TW of firm power generation sources (peak summer power plus reserve margins).
Converting most transportation to electric, converting space heating to electric (direct/heat pumps), and electrolyzing hydrogen feedstocks, etc. will increase our demand in, say 30 years, from 451 GW to 1,400 GW (3x).
Power transmission lines are rated at the peak load, summer for most of the USA. In 30 years there will be a massive peak on winter nights, as heat pumps will consume 3x more in winter than summer with much higher differential temperatures. So we will use a 2x factor for the peak load that power transmission lines will need to carry. WE WILL NEED 2X TIMES 1,400 GW of power transmission line. So we need power transmission lines to carry 2,800 GW.
Most new power transmission lines today are 345 kV lines that carry 400 MW (peak loading) out to 300 miles (745 kV still rare).
But wind and solar have very large peak loading compared to demand load variation. Unless you want to seriously curtail wind and solar output peaks ("throwing-away" a lot of energy), you will need to further de-rate the transmission line capacity by 1/3rd (400MW >> 267 MW).
So you now need 2,800 GW / 267 MW = 10,490 power transmission lines of length 300 miles.
THAT WOULD BE 3 MILLION MILES OF POWER TRANSMISSION LINES.
Why do I assume that each of the roughly 10,000 transmission lines will be 300 miles long?
BECAUSE RENEWABLES (wind/solar) ARE COMPLETELY INCOMPATIBLE WITH OUR CURRENT, RATHER BRILLIANT, GRID ARCHITECTURE.
90% of the US population lives in cities 200,000 people and larger.
And for most of the USA, power generation sources are built directly in, or directly surrounding these cities with minimal transmission line lengths (under 30 miles). It is like an island with multiple generation sources, and a network of transmission/distribution lines that provide a robust network of redundant generation sources and redundant pathways to your home.
Yes, there are some power transmission lines that link city to city, serving rural communities in-between, but very little power flows as these transmission lines are exceedingly expensive and carry far less power than you think.
It is this brilliant architecture that allows for inexpensive growth due to increase in population/industry in cities. Addition of a new power generator typically requires less than a mile of new transmission line to join the localized network.
ENTER WIND/SOLAR. These are NEVER close to population centers (200k+). They are typically 200 miles plus away. AND RARELY DO THEY INSTALL THE NEEDED TRANSMISSION LINES TO BRING THAT POWER TO THE CITIES. Today, they mostly feed the surrounding, more rural communities, and with limited line linking to the far away city, they are often curtailing the output from those renewable plants.
A 300 mile long 345 kV line that can carry peak load of 400 MW will cost 300 x $5.5 million/mile = $1.65 billion dollars alone.
A 400 MW natural gas plant located near the city will cost $400 million including transmission line to join the localized network. SEE THE PROBLEM?
THERE IS A FUNDAMENTAL INCOMPATIBILITY OF THESE PARADIGMS, AND NOBODY HAS EVEN PROPOSED A "NEW" GRID ARCHITECTURE THAT PROVIDES COST EFFECTIVE REDUNDANCY AND EASY INCREMENTAL (organic) GROWTH.
p.s. And all AC power transmission lines have a practical limit of about 300 miles, regardless of line voltage. Yes, you will see longer lines on a map, but in 99% of the cases, there are other generation sources that feed that line at intermediate points. (St. Clair Curve). A major problem for renewables.
I do need to look into the EROI calculations, SmithFS.
I haven't gone down that road, as every other road in this story is just plain ridiculous.
Wind and Solar are both HIGHLY SEASONAL. And the energy storage you need to handle the massive seasonal fluctuation of both wind and solar is impossible. I have downloaded the hourly data that is stored by the US government at EIA website and have analyzed in MathCAD to find the needed energy storage (not a guess, but EXACTLY, with no uncertainty).
Solar against demand needs about 45 days of storage at the annual average power production from PV farms. Wind needs about 55 days of storage at average annual wind production.
So if we match up an average annual demand of 1,400 GW (per my original comment) to wind that produces an average annual of 1,400 GW, we need 1.4E12 x 24hrs/day x 55 days =
= 1.85 PWh of energy storage to not have any blackouts (no reserve margin in this calc).
That would be 474 MILLION Tesla MegaPacks (3.9 MWh each) costing about 850 TRILLION dollars (nearly a quadrillion). At worldwide production of lithium batteries at about 500 GWh annual today, that would take about 3,700 years of production at current rate.
Let's take a reasonable size Pumped Hydro Facility at 10 GWh. It would take 190,000 pumped hydro facilities of that size (about a quadrillion dollars), and again, there just are not even wildly close to the number of potential storage sites in the USA for that.
Hydrogen storage? It would have to be in rather rare Domal Salt caverns. The biggest, at 500,000 m^3 stores a net of 32 GWh. You would need about 58,000 of these caverns (assuming 100% round trip efficiencies). And there is not even close to that number of potential sites (on Gulf Coast, a few in Utah). Perhaps 2,000 caverns total. And it will require about the entire water volume of Lake Erie to to manufacture those caverns (no problem if made right in the Gulf coast).
----------------------------------
Now the good news is that if you overbuild your wind and solar resources by a factor of "2X", you can reduce the energy storage needs by 10-15X.
But the energy store numbers are still impossibly high, and now consider:
When you overbuild your wind and solar by a factor of 2X, you are throwing away 50% of the power those plants can produce. So Capacity Factors drop to the low teens. A HUGE waste of precious raw material resources and land.
And you are running out of room in the United State to site these plants.
Let's take wind:
1,400 GW annual average actual / 0.31 = 4.5 TW nameplate wind required.
Land Area:
4.5E12 / 1E6 = 4.5E6 MW nameplate
4.5E6 MW x 80 acres/MW= 360E6 acres = 563,000 miles^2
Now let's overbuild wind by 2x 4.5E6 >>> 9.0E6.
THAT IS 1.1 MILLION SQUARE MILES, AND EXCEEDS THE ENTIRE UNITED STATES LAND POTENTIAL FOR WIND (by government estimates).
You are out of raw land resource before you even begin on this journey.
Yes, but Trump and LNT grifter-in-chief Robert F. Kennedy Jr.. aren't going to put America on a nationwide electrical infrastructure campaign.
Rather the opposite. Shutdown City. LNT City.
Brilliant work sir. Hilarious metric, l will be linking this one to my friends who are fans of SI units or Dwight yoakam.

Great article as always
Even if they succeed, the increase in fires (see California) will offset any CO2 reductions from electric

AKSHUALLY
the New York Times is basically a disinformation outlet for leftist bias
this should be accepted by any mature adult
Sheldon Whitehouse is a national disgrace
it is really a question of how bad do things have to get before the lunacy of decarbonization is accepted?
Another great article. Informative, data-driven concepts, serious and thoughtful, addressing technical issues and offering feasible solutions. Thank you for posting.

Nuclear. Nuclear. Nuclear. The only answer.
How does nuclear expand the grid?

Yeah, like that’s ever gonna happen.
It’s happening in Canada. And in California governor Newsom has extended the lease of Diablo Canyon nuclear power plant. It’s a start anyway
Extended a lease you say. Some serious investment right there.
Progress, not perfection. Did you get the part that new plants are being built in Canada?
Nevers say, Never! But you are right. North America has to feel alot of pain before anything changes.
If you had said that "they" would spend our money (to no good end) like drunken sailors, you would have insulted drunken sailors ... but at least as the joke goes, it is the sailor's money.

Can we put you in charge?
More exposure of the giant green scam!!!

GigaWatt-Miles is a worthless statistic, as the length of the transmission line has a huge impact on its load-carrying capacity.
Here is a back of the napkin attempt to quantify.
YOU WILL NEED ABOUT 3 MILLION MILES OF NEW POWER TRANSMISSION LINES THAT WILL COST TENS OF TRILLIONS OF DOLLARS.
