Discovered this brilliant website which has a meter which attempts to monitor the power balance of the UK electricity grid. If the needle is too far to the left, it means more generation is needed to meet demand.

The meter actually shows the grid's "frequency", which is related to the speed of rotation of generators all over the country. When there is too little power available, the whole grid "slows down" and the needle moves to the left.

Now resisting the temptation of running around the house turning appliances on/off in an attempt to affect the meter!
