Right now Sweden has adequate baseload, they are well positioned to go with more renewable.
UHVDC and HVDC links can be used to transmit power over thousands of kms. I think the longest line currently is in China a 1100kVDC line that stretches over 3300kms.
Even with conventional AC transmission, power generated in Churchill Falls and James Bay eventually ends up in population centres in Southern Canada and New England.
Losses are a lot lower with DC transmission, but it has been traditionally more expensive. Costs are coming down now as more research and better power electronics are becoming available.
Edit. Here’s a pretty well know one in the US, the Pacific Intertie

Huh, interesting, I was under the impression that losses at distances like that would make it impractical
