Once you fixed the Power Plant, go to the end of Route 25. Talk to Misty and she'll return to the gym. Then you can beat her. (She uses water Pokemon so I suggest you use grass or electric Pokemon.)
you can find her at the end of route 25 after finding the missing power plant peice and bringing it back to the power plant. hope i helped
