Sorry about the link...the Seattle Times has gone to some crap subscription program.
The items in the article elaborated on the issues with the power panels, and gave more detail of several flights, including ferry delivery flights, that had to return due to error messages in the flight deck. Panels were found to have shorted out, with one charred.
There is of course, the story regarding the panel 'fire' on flight test..
A failure in the P100 electrical panel of Boeing’s second flight-test 787 Dreamliner led to Tuesday’s fire, which involved an insulation blanket, Boeing said Thursday.
The company said it was still investigating how the incident happened and what steps might be needed before returning 787s to flight testing.
“We have determined that a failure in the P100 panel led to a fire involving an insulation blanket,” Boeing said. “The insulation self-extinguished once the fault in the P100 panel cleared.
“Damage to the ZA002 P100 panel is significant. Initial inspections, however, do not show extensive damage to the surrounding structure or other systems. We have not completed our inspections of that area of the airplane.”
Boeing has removed the panel and nearby insulation material and is sending a replacement panel to Laredo, Texas, where the jet landed Tuesday, the company said.
The panel receives power from the left engine and distributes it to aircraft systems. Backup systems — including power from the right engine, the Ram Air Turbine, the auxiliary power unit or the battery — are designed to automatically engage in such incidents and did so Tuesday, allowing the crew to maintain positive control of the airplane and land it safely, Boeing said.
“Molten metal has been observed near the P100 panel, which is not unexpected in the presence of high heat. The presence of this material does not reveal anything meaningful to the investigation,” Boeing said.
Inspection of the surrounding area will take several days and is ongoing. It is too early to determine if there is significant damage to any structure or adjacent systems.
As part of our investigation, we will conduct a detailed inspection of the panel and insulation material to determine if they enhance our understanding of the incident.
We continue to evaluate data to understand this incident. At the same time, we are working through a repair plan. In addition, we are determining the appropriate steps required to return the rest of the flight test fleet to flying status.
