To answer that, Mr. Falk, I think I'll build on one of your questions to Mr. Robertson. With very low levels of penetration of wind and solar, the transmission just simply isn't required. Storage isn't a problem, because the demand is there and it soaks it up. When you begin to have higher penetrations of wind and solar, that's when the interties are required.
A direct response to your question is that right now they are satisfied, but if we do build out more wind and solar, then they will need storage, be that hydro dams or batteries, curtailment, a variety of different solutions, or interties. In most modelling exercises that I've seen, strategic transmission has been one of the things that are best able to manage higher penetrations of wind and solar.
