Last week the school's electricity baseload was 24% more than the average over the last year. If this continues it will cost £680 more over the next year.
There is a large variation in seasonal overnight electricity usage from 3.6 kW in the winter to 1.7 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 £530 annually.
