The city of Shenzhen flips the switch on the world’s first fully superconducting urban ring main: 180 km of buried hydride cable carrying 8 GW at 20 °C with water cooling and zero transmission loss.
Peak demand for the city’s 18 million residents: 12 GW.
The ring is fed by a mix of solar, nuclear, and imported hydro — but the key fact is that from the moment the cable closes the loop, line losses drop from 6–8 % to 0.00 %.
Electricity inside the ring is now effectively infinite for practical purposes.
The same month, Hamburg completes a 42 km superconducting link between offshore wind farms and the city center.
Seoul energizes a 68 km metro-area loop.
Austin, Texas, finishes a 91 km demonstration ring funded by a consortium of data-center operators desperate for lossless power.
The grid flip has begun.
Electricity is no longer transported — it is teleported.
The superconducting grid map – end of 2037
| City / Region | Length deployed (km) | Power rating | Loss reduction | Wholesale price impact |
|---|---|---|---|---|
| Shenzhen metro | 180 | 8 GW | −100 % | −38 % (daytime negative) |
| Guangdong province links | 420 | 22 GW | −100 % | −44 % |
| Hamburg + North Sea wind | 112 | 6 GW | −100 % | −52 % |
| Seoul metro | 68 | 5 GW | −100 % | −41 % |
| Austin data-center ring | 91 | 4 GW | −100 % | −61 % |
| Tokyo pilot loop | 54 | 3 GW | −100 % | −36 % |
Total global superconducting cable in service by end-2037: 1,180 km
Enough to carry roughly 60 GW with zero loss — more than the peak output of France’s nuclear fleet.
The price crash – 2037 averages
| Region | 2026 wholesale price (USD/MWh) | 2037 wholesale price | Negative pricing hours/year |
|---|---|---|---|
| Guangdong | $48 | $18 | 1,840 |
| Texas (ERCOT) | $52 | $11 | 2,210 |
| Germany | €72 | €14 | 2,680 |
| South Korea | $62 | $21 | 1,620 |
Negative pricing — when generators pay you to take power — becomes routine during solar peaks and wind surges.
Utilities in Texas and Germany report paying customers to use electricity for 28–34 % of annual hours.
The immediate winners and losers – 2037
Winners:
- Data centers: relocate to superconducting rings, energy costs drop 92 %
- Heavy industry: aluminum smelters, hydrogen electrolysis, desalination move next to zero-loss nodes
- Fusion startups: Commonwealth Vulcan achieves Q = 28, net power to grid December 2037
- EV charging: free supercharging becomes standard (Tesla flips the switch in Austin ring)
Losers:
- Coal/gas peaker plants: 71 % retired or mothballed
- Traditional transmission owners: asset values down 88 %
- Copper producers: mining output cut 62 %
- Oil demand: down another 18 % (electrification accelerates)
The first negative-price city – Austin, October 2037
For 41 consecutive hours, wholesale electricity in the Austin ring goes negative −$42/MWh.
Data centers and crypto miners (the few still operating) run at max load.
Residential rates: $0.00 flat, with credits for high usage.
The local utility sends a letter: “Your bill this month: −$41. Thank you for helping balance the grid.”
The geopolitical ripple – December 2037
Saudi Arabia announces “Vision 2035 Supergrid”: 12,000 km of hydride cable linking solar farms to Europe and Asia via undersea tunnels.
Estimated electricity export revenue: $280 billion/year by 2042.
Russia quietly shelves Nord Stream 3 gas pipeline plans.
The quiet quote from the lead grid engineer in Shenzhen, watching the zero-loss dashboard on launch day, July 2037
“We just turned the city into a superconductor.
Power goes in one side, comes out the other, nothing lost.
No heat, no waste, no limits.
In a few years we’ll forget what an electricity bill even looked like.
The grid isn’t carrying power anymore.
It’s just holding it still until someone needs it.”
By Christmas 2037, the first major cities are running on power that doesn’t degrade over distance.
The old world of scarcity, brownouts, and transmission towers is already fading into history books.

The losses are gone.
The future is lossless.
