There is a large variation in seasonal overnight electricity usage from 36 kW in the winter to 24 kW in the summer. This suggests electric heating is left running overnight during the winter or the school has inefficient security or flood lights. Change electric heater settings and improve lighting efficiency to save £4,700 annually.
