The boss of one of the world's biggest renewable energy companies believes people in the UK could get free electricity on certain days of the week.
EDF Renewables chief executive Matthieu Hue said plans to increase the capacity of renewables such as wind and solar in Scotland meant supply would sometimes exceed demand, driving down prices.
Speaking at the Labour Party Conference, Mr Hue said: “Demand is not the same every hour of the day, or every day of the week. There are a number of companies, including EDF, who believe that electricity will be free [at some times] – perhaps on a Sunday.
“This will also be made possible through the installation of smart meters which let people see what energy they are consuming.”
According to The Telegraph, Mr Hue said Sundays were the most likely day that energy would be made free for households, because demand for electricity was usually lowest when many businesses were closed.
EDF has around 47 renewable energy sites across the UK, including 10 onshore windfarms in Scotland, collectively producing about 2.5 gigawatts (GW), roughly enough to power two million homes.
