Narrative:

Our aircraft experienced a right generator failure. This was MEL'd per company specifications. We then flew a reposition flight with the right generator still MEL'd. On the next flight with passengers on board; while on initial climb; we experienced a left generator failed cas warning; leaving aircraft only being powered by the APU generator. Crew diverted to another airport where we tail swapped and continued to our destination on another aircraft. We wrote up the broken airplane and left it for maintenance. Passengers had no concerns.
