NIce well designed resource. However, I think transformers are beyond the scope of KS3 . Also, you incorrectly describe electricity as being "stored" on the National Grid. If only it could be!! It will flow through whatever devices are connected to the grid - mobile phone chargers, aluminium smelters, and everything in between these extremes - where the energy is converted to another form. If there is an over-supply of electricity this leads to an increase in the a.c. frequency, which is dangerous if it gets too big, so the power stations have to curtail their output. If there's not enough the frequency goes down, and the power suppliers get the signal that they have to increase supply to the customers, by burning more fuel, opening dams in hydro stations, etc. It's a complex business, but, fortunately beyond ks3
