Maybe you could call the electric co and tell them they are out of town for a funeral and could the power be put back on for a couple more days until they can get it paid? Maybe the power co has some compassion. If it was cut off though the payments are probably a couple months behind. I guess wait for her to contact you. Put some candles out for her and maybe a flashlight or 2 so when she gets home she will have some light. Take care.
