A321 pilot reported failure of the number 2 generator resulted in single generator operations. The flight crew made a precautionary landing at diversion airport where the aircraft was taken out of service.

Narrative

We were operating Aircraft X (ZZZ - ZZZZ) with a deferred APU and CPC2 (Cabin Pressure Controller). A little past midway into the flight we received an ELEC GEN 2 FAULT ECAM and a FAC 2 Fault. We proceeded to run the non normal procedures for both issues. The FAC 2 fault cleared after completion of the ECAM procedure; but the ELEC GEN 2 FAULT did not reset successfully; so we proceeded to the QRH with no success. At that point; we were single generator operations and considering diversion options; so I contacted Operations Control. Operations Control decided we should divert to ZZZZ. We; along with Dispatch decided that was the best option and changed our destination with ATC. We then communicated our plan to Inflight and the customers. We designated this issue as an urgent briefing to Inflight and gave them time to landing. We [advised ATC] as a precaution and to receive priority handling to ZZZZ. The flight landed uneventfully and the aircraft was then taken out of service by Maintenance.
