Wasted wind power adds £40 to household energy bills, says think tank
That figure could increase to £150 in 2026, Carbon Tracker has estimated.
When it is very windy, the grid cannot handle the extra power generated. Wind farms are paid to switch off and gas-powered stations are paid to fire up. The cost is passed on to consumers.
The government said major reforms will halve the time it takes to build energy networks to cope with extra wind power.
