Narrative:
We were pushing from gate and shortly after the captain asked me to start the number 1 engine we heard a loud explosion and the aircraft went electrically dark. Power came back online almost immediately most likely as a result of the engine driven generation coming online. As we were attempting to assess the cause of the explosion; rampers began yelling that they saw flames and smoke coming from the tail of the aircraft. While the captain was trying gather information from the rampers; I referenced the qrc for APU fire and found the appropriate page in my QRH. The information we were gathering from outside the aircraft made it sound like there was no present fire; but they did tell us there were parts of the APU on the ground. The APU had automatically shut itself down (or failed) and there were no fire indications displayed in the cockpit. The captain spoke with our number 2 flight attendant and assessed no flames; fumes or smoke in the cabin. I quickly asked ramp if we could take gate as it was unoccupied and we are pointed directly at it. I then needed to confirm the request with ground and told them we would need emergency personnel and firetrucks to assess the exterior of the aircraft. Emergency responders were quick to arrive and report no flames or smoke outside the aircraft. We arrived safely at gate and deplaned.
