There Aren't Enough Cables To Meet Growing Electricity Demand (bloomberg.com) 56
High-voltage electricity cables have become a major constraint throttling the clean energy transition, with manufacturing facilities booked out for years as demand far exceeds supply capacity. The energy transition, trade barriers, and overdue grid upgrades have turbocharged demand for these highly sophisticated cables that connect wind farms, solar installations, and cross-border power networks.
The International Energy Agency estimates that 80 million kilometers of grid infrastructure must be built between now and 2040 to meet clean energy targets -- equivalent to rebuilding the entire existing global grid that took a century to construct, but compressed into just 15 years. Each high-voltage cable requires custom engineering and months-long production in specialized 200-meter towers, with manufacturers reporting that 80-90% of major projects now use high-voltage direct current technology versus traditional alternating current systems.

China's start to the construction of 94.5 gigawatts of new coal-powered capacity and resuming construction on 3.3GW of suspended projects in 2024, all fueled by investment from the coal-mining sector, would suggest otherwise. Analysts may expect that China's expansion of its clean-energy capacity will slowly squeeze out coal's share of its electricity generation, but their rapid coal-power expansion is posing a "challenge" (it's amazing how "challenge" sounds so much better than "major stumbling block") to their high-level climate commitments, including commitments on reducing coal use.

Back in 2014, the European Union fined all the big cabling companies for collusion. And I read through those documents. And they would go around the world and stay at hotels and talk together, and they basically say, ‘Okay, you Europeans, you stay in your market, and we Asians will go in our market.’ And if they got a request for proposals, then they would let each other know and make sure that the right bidder won the contract.
They've been fined, and today, they would say that's all in the past and I think if you look, there's no evidence that it's still going on. But if you look at it, there's kind of no reason to continue colluding; there is so much demand and constricted supply. One of the CEOs I spoke to for the story, I asked him, ‘what do you think of the competition?’ And he said to me, ‘everyone is behaving.’ So if everyone is behaving, everyone is trying to keep prices at a good level for everyone else, there's not so much expansion of supply, then there really wouldn't be a need to collude, even if they wanted to take that risk again.

I agree that adding more solar power capacity is nonsense when the rates go negative because of overproduction. That's just asking to pay out for solar panels, then pay again for the ability to put electricity on the grid.

The cables aren't the bottle neck. It is getting approval to buy them. The electric utilities in most of the western world are guarenteed a return on any capital investment usually of between 11% and 13%. In return they have to go to the public regulators to get approval for any capital expenditures. It is the regulators that won't approve the spending of money on new transmissions.
You're lumping the "western world" together in a way that I can't agree with. Having been to several "western world" countries I've never seen a capital investment return requirement for grid transmission (doesn't mean it doesn't exist, just that it's not common). Are you confusing new generation projects (which in turn also require cables)? The approval for purchasing cables is largely rubberstamped in countries where grid expansion is big issue (e.g. much of Europe where electrification is a big agenda).
