Think of pumped storage like a battery: In areas with a lot of solar, pumped storage runs when there is a lot of daylight to store the energy for nighttime use. Pumps run when the sun is out, turbines run at night.

Or the opposite in areas with wind/nuclear. Pump it up during the night when demand and prices are low, then run turbines during day when demand and prices are higher. Arbitrage.
