So, "they" want to build an undersea power connection from Canada to Europe. Communications links are technically complex but well-understood at this point. Long distance (4000 km) power transmission is a whole 'nother kettle of fish.
The technical summary is fascinating:
https://nato-l.com/documents/2607-JDN-NATO-L-Executive-Summary.pdf2 GW transmission at 525 kV - or possibly 800 kV in another installation - is impressive. Sudden failures at that power level tend to resemble major bombing campaigns rather than electrical failures.
It will be interesting.

Har energiomställningen tappat fart? Inte alls, enligt Nuria Criado Alvarez, Hitachi Energy Power Consulting. • En sak överraskar i den globala elektrifieringen.#elnät #topp #elsystem #hitachienergy #hvdc #energi

En 680 km lång elkabel för högspänd likström ska dras mellan Skottland och England. Det kan gynna Hitachi Energys verksamhet i Ludvika.

🔐 Practical Industrial Security: Real-World Lessons from Complex HVDC Projects
We’re excited to announce that our colleague Jan Grotelüschen (GAI NetConsult GmbH) will be speaking at the Industrial Security Conference 2025 in Copenhagen, alongside Simon Gustafson (Amprion GmbH) and co-author Stephan Beirer (GAI NetConsult GmbH).
🎤 Topic of the presentation:
Staying on course in a volatile environment: OT security in complex large-scale HVDC projects – a real-life example⚡ At a glance:
Amprion is currently implementing massive offshore grid connection projects such as BorWin4/DolWin4 and BalWin1/BalWin2. These high-voltage direct current (HVDC) lines span up to 380 km and deliver 5.8 GW of power per project – enough to supply electricity to nearly 6 million people.
In this presentation, the speakers, who are largely responsible for the specification and monitoring of the implementation of OT security for this HVDC project, will present the projects itself and report on the cyber security challenges and lessons learnt.🔍 Key OT Security Challenges Covered:
• Dynamic regulation: Adapting to evolving frameworks like NIS-2, RCE, CRA – even mid-project
• Technology vs. longevity: IT/OT convergence meets decades-long system life cycles
• Managing uncertainty: Constant change in technologies, requirements, and stakeholders📌 This session provides real-world insights into securing critical infrastructure under real conditions – including what worked, what didn’t, and how lessons learned are shaping better security strategies.

Alweer een energieransitie idee dat weggehoond werd, maar waar nu volop in geinvesteerd wordt. In Marrokko schijnt de zon constant en de wind waait elke avond. De afstand is een probleem, maar met hvdc kabels heb je zeer lage verliezen. #energy #renewables #morrocco #hvdc #energietransitie https://www.youtube.com/watch?v=-VtFmU5-ESw

525kV lines coming to the US also:
"SunZia Transmission is a 550-mile ± 525 kV high-voltage direct current (#HVDC) #TransmissionLine between central New Mexico and south-central Arizona with the capacity to transport 3,000 MW across Western states. SunZia Transmission will deliver power generated by Pattern Energy’s 3,515 MW SunZia Wind facility (the largest wind project in the Western Hemisphere), which is being constructed in #NewMexico."

HVDC Networks Come to Europe
"Driving this expansion in #HVDC are major technical advances.
The flexible control over current and voltage is the hallmark of voltage-source converter (VSC) technology.
Germany has led #standardization TenneT asked all of its suppliers to offer compatible 525-kV HVDC systems with room for extra switchgear, creating the option to interconnect today’s segments in larger networks."
Bring it on!

"...we are past the point where the actions of individual countries can move the needle on #ClimateChange."
Doing Everything, Everywhere, All at Once is the only viable #climate change mitigation strategy that can possibly save #human #civilization and our #species.
On national and international scales, we must all work together on projects like building #HVDC #SuperGrid connectivity.
#Decarbonization is both a #security and #existential necessity.

A short documentary about supergrids, HVDC power lines, their technology and politics behind building them.
TransWest Express is mentioned, in development for 15 years finally was allowed to start construction and is expected to be operational in 2027.

UK, Netherlands plan 1.8 GW 'hybrid interconnection', connecting a Dutch offshore wind farm to both countries, and providing extra interconnection capacity at the same time.
Useful given the time difference in the occurrence of high and low wind speeds.

"For $35 billion CAD, #Canada could have had a massive 10 to 15 GW #HVDC line linking Canadian provinces and linking down into the US in multiple points to bring clean #renewable #energy from wherever it happened to be in surplus to where ever it happened to be in demand.
It could run along the rail lines as part of an overhead catenary electrification of rail as a strategic national initiative, decarbonizing that key transportation segment."

"Researchers at Oak Ridge have developed a design and control system for a solar and storage plant that can provide power to BOTH AC and DC high-voltage lines. As a result, #renewable power can be more easily and reliably transmitted.
MARS ... is an all-in-one package that includes power electronics, electrical architecture, and #cybersecurity software. And because it’s plug-and-play, it’s easier and cheaper for utilities to get it online."
