Why would you need cooling if you are trying to heat water up. It just seems like wasted energy to me.

You’re trying to heat water, yeah. But you *don’t* want literally everything else in your power plant to heat up to the point of melting, so you circulate more water through it to cool it down — then you reject that heat through the cooling tower. You also need to cool down the water you just heated up so that you can heat it up again.
