My experience would be that having a portfolio of energy is a more robust solution. Having a number of sources of energy is an appropriate strategy. I think it's very much a decision of a particular jurisdiction how much they want to put in the hands of another jurisdiction.
From a reliability standpoint, the bulk power grid has mandated requirements for how big the lines are, where the generation is located, and how the capacity is counted. There are bulk system reliability requirements that always need to be adhered to. There are some guiding principles around these.
What I think your question goes to is more the commercial risk between various jurisdictions, and I don't think I can answer that one clearly. I can talk about the bulk power system. I know that you can build a bulk power system that takes generation from afar and brings it near. You can do it reliably; there are ways to do it.
The question, then, is your comfort with the counterparty.
