Long term commitment is something I hadn't thought of, but a very important one, like building a superhighway to a city not yet built. I was too busy thinking of the technical challenges. Just reading up on (I guess the term UHV is now redundant) HVDC and HVAC interconnections, and line phase always fascinates me, I'm an electronic tech, not electrical, and I presumed the DC was xmtted in ripple form, perhaps not, so *synchronizing phase* becomes a very real challenge. I'd presumed injecting a control signal into the switching control banks like is used for solar panels to an inverter would establish that, evidently not that simple:

Some of this I knew, some I didn't. Now reading back some of the chapters. Incredibly well written Wikipedia piece, it must be from an engineering manual. And I see a lot of my questions being answered.
From what I gather from a quick glance, the only sane way to xmt pwr from PQ to Ont is HVDC. And the investment would be huge. Why have I spent so much forum space on this?
Because this subject if going to come up time and again, and be recklessly based on complete misinformation.
Incredible! I just sent that link off to friends and associates. Cynthia Mulligan has impressed me many times. She's far more than just eye candy.

@lenaitch especially, you have the capacity to appreciate this:
Off topic, but remember the "disappearing energy" in the Southern European network last year, such that "clocks were running slow" (synchronous, of course)?
I still don't believe the story being touted for it, won't go into the technical details, but suffice to say generators would be programmed to disconnect if line freq was more than a few radians late or early:

I don't believe it! Traced the story, Deutsche Welle and many other reputable popular sources and some universities and even science sites were in on the story. I'm sure there is a real story, just not this one...
