We taxied out and we're on the ramp with Ground when ALL flight instrument and ECAM screens along with Control Panel lighting went out for approximately 4-5 seconds. Power was restored and; after evaluating the situation; we accomplished the QRH procedure for a #1 generator failure. It would not reset so we returned to the gate after notifying Ops/maintenance. Maintenance deferred the #1 generator; but I let them know that I felt the aircraft did not properly switch power sources. Cockpit should not have lost 'all' power (screens; instruments and lighting) for that long. With summer thunderstorms along the whole route I did not feel that taking this aircraft was a smart/safe thing to do. I refused the aircraft. Dispatch had another aircraft available.
A319 Captain reported a #1 generator failure on taxi with no reset and no automatic switching of load. Captain refused to take the aircraft and flight was switched to another aircraft.
