Narrative:

Shortly after setting takeoff thrust; the left generator tripped off line. Captain announced the abort; reduced thrust to idle; and confirmed they had control of the aircraft. Since our airspeed never exceeded 50 KTS; minimal braking was required. We exited the runway and taxied onto taxiway charlie to check the problem and eventually returned to the gate. During and immediately after the abort; we failed to complete the aborted takeoff checklist; instead focusing on the checklist for the generator problem. The aborted takeoff procedure and philosophy at our airline has recently undergone significant change that was not ingrained and reinforced with the flight crews by simulator training; instead having been only mentioned and briefly reviewed in a power point presentation. In the heat of the moment; we reverted to the old habits and procedures we have been practicing for many years. Fortunately; due to the low speed of the abort; when we finally realized our oversight and found the appropriate checklist; all items were completed.
