There was a 1.4% reduction in electricity consumption on 24 Feb
A total of 29,580 kilowatt (kW) hours of electricity were saved in one night in Notts as part of an experiment.
That is the equivalent to 887,000 2kW boiling kettles.
The Energy Experiment, which took place on 24 February, 2010, aimed to see how much consumption could be reduced by switching off appliances.
Hundreds of households, council buildings and businesses took part in the event which was the idea of BBC Radio presenter Andy Whittaker.
Listeners to BBC Radio Nottingham were asked to switch off unused appliances at the plug and turn off lights when rooms were empty between 9.00pm on Wednesday, 24 February and 6.00am the following morning.
They were urged to tell their friends to do the same.
Central Networks monitored the difference this made in power consumption during the experiment, comparing it with a normal day in the weeks prior the event.
The result shows a 1.4% reduction in demand on the network during the given period.
This was the second Energy Experiment in Nottinghamshire. The first experiment in February 2009 saved a total of 14,150 kilowatt hours of electricity or 425,000 boiling kettles.
