The bigger the land mass, the better. You also overbuild by a bit to handle droughts, and curtail in normal periods. In the circumstances that it still happens, you use natural gas as a backstop, or you use long-duration clean storage like hydrogen (which remains more hypothetical/expensive currently, but that will change).
