British Gas has said it could offer free electricity on Saturdays in a bid to reduce demand on weekdays.
The energy firm has announced plans to trial the initiative and could make it available to customers by mid-2014.
Centrica already offers a Free Energy Saturdays tariff to customers in the US.
A spokesman for Centrica said: "Our North American business offers a product for those customers in Texas who have a smart meter. Once we have trialed it, if it works then we could potentially offer it as a product for customers from the middle of next year."
One million UK homes and businesses already have smart meters installed, which automatically send readings to British Gas. Centrica hopes the scheme will encourage households to use electrical appliances at the weekend, when industrial demand is lower.
