Everyone should winterize their electrical power grids. But each grid will encounter winter conditions that are extreme compared to the usual winters. For that, what you need is a robust grid with (for example) some nuclear plants with fuel stored on site, so the problems of winter do not become grid-wide catastrophes. Just-in-time renewables plus Just-in-Time natural gas is a recipe for the kind of disaster Texas had, and the kind that is embedded in many of ISO-NE’s future scenarios.
