Your electricity baseload over the last year of 3 kW is high. Other schools with a similar number of pupils have a baseload of 2.5 kW.
This chart shows your electricity baseload over the last year. This is the amount of electricity you use overnight when the school is empty.
The Problem Your baseload over the last year of 3 kW is high. Other schools with a similar number of pupils have a baseload of 2.5 kW.
Electricity baseload is the electricity needed to provide power to appliances that keep running at all times. It can be measured by looking at your school's out of hours electricity consumption.
Reducing a school's baseload is often the fastest way of reducing a school's energy costs and reducing its carbon footprint. If you matched the baseload of other schools of the same size you would save £550. If you matched the baseload of the best performing schools you could save £1,600.
Common causes A high baseload is often caused by:
Old freezers and fridges running constantly
Inefficient IT servers
Electric water heaters
Computers, whiteboards and other electrical equipment left running when the school is closed.
What you should do Reducing a school's baseload is often the fastest way of reducing a school's energy costs and reducing its carbon footprint. For each 1kW reduction in baseload, the school will save £1,050 per year, and reduce its carbon footprint by 2,400 kg.
Find out whether any electrical equipment or lights are running all the time. Do they need to run all the time?
You should check to see what lights and appliances are left on at the end of the school day and get pupils and staff to switch off lights and appliances when they go home, and before the school holidays. Don't forget to look in offices or school kitchens.
Use appliance monitors to check how much energy your school fridges and freezers are using, as these need to run all the time. A modern fridge or freezer uses £30 to £40 of electricity a year, but old models can use up to £500 of electricity a year.
Consider replacing old ICT servers with modern servers or move to saving your school's data in the 'cloud'. Removing the need for school ICT servers can also save energy previously used for air conditioning in school server rooms.
