The main power draw in the galley is the oven. On long haul it operates at meal times, and that depends on the time of the day the flight is taking place. On low cost airlines it operates when someone orders a hot food product - ie. randomly.

Electric anti-ice (apart from the windows) is rare, it's normally pneumatic (pressure or hot bleed). Power requirements are thus fairly constant throughout the flight.
