Human Factors
On climbout from ZZZ passing 14000 ft my first officer noticed that the generators were not connected to the electrical system. I connected the generators and ran the after start check list; the flight proceeded normally.It was the last flight using the old procedures and we were studying the new procedures. I got out of sequence and forgot the after start procedure and the call for the after start checklist.
Congested ramp during push back. Delayed starting engine 1 for confusion over traffic in ramp. Finished push and engine 1 and 2 were normal starts. Taxied out to a normal take off. Weather in area and icing. After takeoff had to confirm climb clearance because First Officer (FO) and Captain (CA) heard different clearances. Lots of ATC handling. Around 13;000 feet FO engaged autopilot. Around 14;000 feet FO reached up to turn up the heat in passenger cabin. That is when FO noticed the blue GEN OFF BUS lights were illuminated. FO brought this to the CA's attention. CA put the generators on bus; rechecked all overhead switches while FO watched and re-engaged autopilot. A lot more ATC handling. Once at cruise FO and CA discussed what happened and came to the conclusion that the After Start Checklist was not accomplished; as well as the CA's after start flow. CA and FO continued to triple check all remaining flows and duties and landed without incident at destination.Fatigue played a factor in that the crew had a very long first day of the trip with an early wake up. Crew commented at destination that they were exhausted and that it was a really long day (about 8.5 flying and 12 hours of duty). Shorter layover for ZZZ. I (FO) planned on getting up a lot earlier than I did in ZZZ to have a leisurely morning; but I couldn't get out of bed. So instead I slept off and on and finally got up in time for a quick workout and a take-out breakfast from the grocery store. Felt fine leaving ZZZ. We had a 2 hour sit in ZZZ1 before the ZZZ2 leg. Now people are starting to show signs of fatigue like yawning. But we felt good to fly and reported for the flight. This was our last leg before our new procedures were to take effect; changing flows and checklists. This was definitely on our minds as we had been talking about it the last day or 2. Before; when CA's started engines I used to hold the checklist in my hands to remember to accomplish said checklist; but now with FO's starting the engines I have to put it down. Before that would have trapped the error of not doing the checklist; but now it didn't and I honestly don't have another reminder yet. I should have noticed the GEN OFF BUS lights at the 10;000 feet pressurization check but I do not know why I didn't catch it then...it just didn't register; which is why I think fatigue was a factor. The distraction of the new procedures was definitely on our minds and also attributed to the mistake.
Flight crew neglected to connect the generators due to not completing the checklist properly. Transitioning from old procedures to new procedures caused the flight crew to get out of sequence while accomplishing the checklist.
