Not sure whether you&#x27;re just using the term incorrectly, but I see this claim repeated a lot so forgive me for explaining: you do not need baseline power.<p>Baseline power is the observation that if we have less than ideal power plants that need to run 24&#x2F;7 to be economical (usually because of high capital costs, e.g. nuclear plants), we can still deploy them if we then also invest in other plants for filling in the peaks.<p>See, the important part here is that you always need to meet demand (maybe you can shift demand around a bit, but after shifting it the observation still holds).<p>If you have baseline plants, your supply curve is a flat line so the peaks in the demand are the holes you need to fill in somehow.<p>With a renewable source like wind or solar, you may actually be able to meet the peak demand, but then have a hole in the supply at some other point (say at night, or when there&#x27;s no wind). So you need to fill in these somehow (as you say).
