People frequently use precursors in order to obtain your attention. It gets more sophisticated as people grow up but children find it effective early on. One of the reasons they are so enamored with it is parents tend to use that phrase with their children quite a bit to make sure they’ve got their attention and the kids just pick it up. So it’s kind of like a baby talk left over

Adult versions are things like 'You’ll never guess what just happened to me" Or “You’re never going to believe this”

He’s a witch! Burn him! BUUUUURN THE WITCH!!!

To be honest, historically and depending on the installation solar power is more useful in the summer or warmer months and dams are less useful because you’re hoping the reservoir fills up and provides power all winter. The reverse is true in the winter we’re damn sure produce more reliable energy but solar power is slightly less available

So to me this sounds like a fairly elegant solution where the dam will now produce large amounts of power throughout the spring and summer months as well as the fall and winter months allowing for more water to be saved up for the winter and more power generation. I’m sure the solar also helps augment the winter as well
