Government and Ofgem must “throw their weight” behind this year’s Demand Flexibility Service (DFS) to maximise its potential this winter, Energy UK has urged. A total of 1.6 million households and businesses participated in the first iteration of the scheme, introduced by National Grid Electricity System Operator (ESO), which ran from November last year to March 2023, delivering in total 3,300MWh of electricity reduction. Speaking to Utility Week Naomi Baker, Energy UK’s senior policy manager, said the message from the trade body’s members “is loud and clear” in that the ESO “can make the service even bigger and better, especially with the addition of greater participation from industrial and commercial customers”.
