The National Grid ESO has confirmed that a Demand Flexibility Scheme test will go underway from this afternoon into the evening.
The scheme was compiled following fears over Britain's energy supply being run thin throughout the winter period. Company chief executives previously said that they hope the scheme would help avoid the possibility of any blackouts when electricity use is at its highest.
It also provides an incentive for households to reduce the amount of electricity they use at peak times to help reduce stress on the national grid. Under the scheme, suppliers can pay their customers to turn off power-hungry appliances such as washing machines and tumble dryers.
