'Households will soon be rewarded for turning lights off at night and heat off in the winter, under official plans to let technology firms like Google and Amazon to provide energy to British Homes.
The Government and regulators want radical new "time of day tariffs", where energy prices fluctuate depending on availability, to be widely used by millions of families by 2020, Ofgem told the Daily Telegraph.
At present only one supplier, Green Energy UK offers a time of day tariff.
But Ofgem has said it will relax licensing and data sharing rules in order to let tech firms introduce the new gas and electric tariffs, which will have more control over appliances in people's homes than traditional arrangements.
Under the arrangements suppliers will be able to switch consumer's appliances - like TVs and washing machines - on or off during times of high or low demand.
The scheme is designed to save billions in electricity bills, but it is likely to raise further questions on privacy and data security for households who choose to move to such contracts to reduce their bills.'
