That's handled by grid-scale storage: Batteries, pumped storage, compressed air. Renewable energy has the same need. BTW, when I was a teenager I got to go deep inside of a mountain to tour a pumped storage facility built to pair with some early 1970s nuclear power plants. The nuclear plants are long-decommissioned, but the pumped storage is happily running with renewables.
