I'll add one more thing. Renewables are a good possibility. The one issue they deal with in the north is that winter is their heaviest load because they have heating load as well as lighting and everything else. There's not much daylight for things like solar. They have to have more storage, and sometimes on the coldest days, there's very little wind. They need a lot of storage in those areas to make it work, and that's the challenge.
