EDF is working to support the continued growth of flexibility services in the Great Britain, helping more customers participate in energy markets through assets such as electric vehicles (EVs), batteries, heat pumps and other smart technologies.
The commitment supports the growing role of flexibility in balancing the electricity grid as renewable generation and electricity demand continue to increase across the Great Britain. The Government’s Clean Flexibility Roadmap has highlighted the need for a significant increase in flexibility capacity by 2030 to support a more renewables-led electricity system.
A key milestone in enabling wider participation is industry rule change P483, which Elexon introduced in November 2025. The change removes barriers that previously limited access to flexibility markets for many homes and small businesses by allowing the use of assets located at sites which have Non Half-Hourly Metering Systems in Settlement. Until now, flexibility providers could only trade flexibility from customers who were half hourly settled, restricting participation to a relatively small number of customers.
The rule change removes this requirement where assets such as EV chargers and batteries are measured using dedicated asset meters. This allows significantly more customers connected through standard electricity meters to participate in flexibility markets for the first time, helping them lower energy costs, unlock value from their assets and support the grid during periods of peak demand. EDF has been helping scale participation in flexibility services across Great Britain.
Christopher Dalley, Director of Business and Wholesale Services at EDF, said, “This industry rule change is an important step forward for flexibility in the Great Britain making it easier for many more customers to participate in energy markets and unlock value from assets such as EVs and batteries. Flexibility will play a central role in balancing a lower carbon electricity system and supporting EDF’s ambition to help electrify Britain.”
John Lucas, Head of Market Design at Elexon, added, “Opening electricity markets to consumer-led flexibility is key to Great Britain meeting Clean Power 2030 targets. However, we need to support people who cannot provide flexibility until their supplier moves their meter to half-hourly settlement. Through the rule change, Elexon is helping to support these consumers and ensure that they don’t miss out on opportunities, maintaining the momentum in flexibility provision.”
