Increasing grid connectivity is certainly happening, but it's not very exciting. You see news about new large undersea connections. There's news from time to time about the Tres Amigos interconnection facility between the US grids in the east, west, and Texas (mostly delays, unfortunately). News here and there about better connectivity between north and south england. Local news about local projects (my area is wiring some leaf substations into a ring; very exciting for me, not much for anyone else; although the why is to provide reliability to a charge an electric ferry that carries 200 cars, so maybe a little exciting?).

A lot of times connectivity impacts site selection of projects. A wind farm needs to have good wind, reasonable neighbors, and access to loads. There's articles about not being able to build more wind in northern england because there's not enough transmission infra to get the power where it needs to be.
