A300 first officer reported that an electrical failure resulted in a diversion.

Narrative:

In cruise we lost the #2 generator. It should be noted that with the same plane the #2 generator failed the flight prior. When the generator failed in cruise we realized that the AC bus 2 also was failed. I was the pilot flying at the time and when this occurred the pfd; nd; went dark and the 2nd autopilot went off. I transferred controls over to the captain and started to run the QRH for a generator fault. After completing that checklist I went to the AC bus off QRH. We were directed to run the increased landing distance procedure and increased fuel consumption. At this point we notified ATC that we had an electrical issue and were limited on capabilities due to the loss of system 2 items. They vectored us to ZZZ at this point. We notified the company and asked for a different alternate airport [because] the weather in ZZZ1 was bad with a line of thunderstorms. We landed without incident.
