Households will be paid to cut their electricity use again tonight under a scheme by the National Grid Electricity System Operator (ESO) called the Demand Flexibility Service (DFS).
The scheme was launched in November last year as a way of saving energy supplies when national demand is at its highest and it was activated for the first time on Monday January 23.
Tonight, the scheme will run between 4.30pm and 6pm and those taking part are asked to reduce their electricity consumption as much as they can during this 90 minute period.
