Power outage is on page 9.
Summary of that section*:
Around 0125, the vessel Dali experienced a critical electrical failure about 0.6 miles from the Key Bridge. Two electrical breakers tripped, causing a blackout that disabled shipboard lighting, equipment, main engine cooling water pumps, and steering gear pumps. Although generators 3 and 4 continued to run, the main propulsion engine shut down due to the loss of power to necessary pumps, and the vessel lost steering capabilities.
At 0126, the voyage data recorder (VDR) resumed recording data, indicating the ship's heading and course had slightly changed, and speed had decreased. The senior pilot, having taken control, ordered a 20° port rudder, and the emergency generator started, providing limited power for emergency equipment, including a slow-moving emergency steering pump.
The crew manually restored power by closing the tripped breakers, but at 0.2 miles from the bridge, a second blackout occurred. The emergency generator maintained power to emergency systems, and generator 2 automatically started, restoring power to the HV bus. The senior pilot ordered the rudder hard to port at 0127:23, but the lack of propulsion hampered steering efforts. Despite the crew regaining electrical power before the ship struck the bridge, they were unable to restore propulsion.

S'pose that's fair. It does seem odd that the report would say the generator was "not configured" to power the ship, rather than not capable of it.
Both of those can be true, no? It was not capable to power the ship because it was not configured to do so.
Maybe. But can it be configured to power the ship? If so why wasn't it?
