There is no requirement that the grid requires "baseload" sources of power. The grid can operate with flexible sources of power that can ramp (gas, some hydro, etc.) in addition to wind and solar. If anything nuclear and coal, which can only run at 80-100% capacity or 0% capacity are inconvenient and inflexible sources of power. The grid survives fine when nuclear and coal plants go offline for several days for maintenance/turn-arounds!
