Not to state the obvious, but im currently studying for my MEIR in about two weeks and we have to know all the little fiddly (admittedly, New Zealand specific, but still ICAO) laws relating to electrical failures and stuff.
if you loose all electrical power you have to proceed with your flight plan as designated in the flight plan, go to destination, and perform approach as per your flight plan's ETA.
so by that, should you not just go ahead with it? surely if he lost ALL electrics then thats the only route. and if he had a partial failure, and the MEL allowed it, then good on him for keeping his job before thinking about little timmy in seat 15B who cant watch some new movie till he sees it in the cinema!
sorry, im ranting again.
