the answer was in relation to a question about what people will experience with HVDC vs the grid as it is now. The answer was that (parapharsed) “end consumers should not experience any difference but grid operators will need to manage up to 3 times the electrical energy” in the system. I will hazard a guess that it is about the generally up to 3x higher voltage of HVDC vs HVAC? (about 26min into the podcast if anyone is interested)
Edit: the word of the day is parapharsed. Used in a sentence: “the new appy does things half-arsed but he is not the worst, the villageidiot does things parapharsed”…
