The North Atlantic Transmission One Link (Nato-L) wants to connect the European & American electricity grids via a 3,500 km cable to share excess renewable energy.
Ireland is at the centre of plans for a powerful new trans-Atlantic electricity link aimed at protecting Nato members’ energy security, the Irish Independent has learned.
Counterintuitively, electricity cables under the North Atlantic might be much more economical. It would not have the eminent domain and construction complexities of upgrading the US continental land grid. If this cost estimate is accurate, it may be much cheaper.
Is it really much more secure though? Wouldn't one well-placed underwater bomb knock it out of action for weeks or months?
If security was your top priority, surely decentralized microgrids with widely dispersed battery grid storage would be much more effective?
There's a similar project that would supply power from Australia-Asia that spans 4,600 km when completed. But such big projects could easily be caught up in various delays, and it's a problem if a country is too dependent on a single power link. Self-reliant renewable energy production definitely seems more secure.
I'm very skeptical of the actual benefit of something like this.
The 6GW system would be made up of pairs of cables stretching about 3,500km across the North Atlantic.
I don't see much benefit unless this becomes cheaper than the cost of building and running the equivalent generation (about two large plants.) Ohio's data center load alone is projected to increase by about 4.5 GW by 2030.
If security was your top priority, surely decentralized microgrids with widely dispersed battery grid storage would be much more effective?
I'd say so, and it seemed like that was the way the industry was trending about 10 years ago but it seems like the large data center demand stalled that considering some of the facilities could use their own generation plant. Plus, the United States already has a precedent of substations being taken down by gun toting idiots.
So 15.75% of the electricity would just vanish. That takes the shine off it a bit although if the price difference is big enough it would still be worth doing.
