Generation and storage definitely should go hand in hand, but I think the Pakistani authorities' desire is simply to have something better than the alternative of not having it. At least Pakistan has plenty of hydropower installations that could potentially be adapted to act as energy storage.

Is that maily using solar panels to power uphill water movement into water reservors?

Either local solar panels, grid power, or a combination of both, yes. And of course solar panels can also indirectly "store" power by simply reducing demand on hydro resources during the day, allowing water to back up for night-time use.
