And perhaps even begin building a superconducting grid ad for once in PG&E's history, doing something that was pro-active rather than reactive.

Is there a superconducting grid anywhere on a large scale? Last time I read up on it, the experiments by Detroit Edison were a failure due to an inability to keep the coolant from escaping because it used liquid helium. This was probably a decade ago. Have there been advances since then?

Large scale, no, but succesful in New York to bridge two power grids.

We don't have the technology for a superconducting grid. It also doesn't really make sense, as grid losses are not that big. On very long connections we might want to switch to HVDC, but keeping superconductors cool would most likely require more energy than you save.
