Pallion is station located between South Hylton and Millfield; two stations where presumably trains are still stopping. Power is needed to make the trains run between these two points. Therefore, Pallion cannot be suffering from a power supply problem unless they're referring to the lights and signage meaning that 'unsafe' to let passengers board/disembark in the dark.
I think it's the stations. Gateshead Stadium was closed for the same reason and it's because the station lights weren't working.
