CrowdFlex Customer Feedback Research Reports
By the Centre for Sustainable Energy for National Energy System Operator
November 2024 – March 2026

CrowdFlex was a two-year National Energy System Operator (NESO)-led innovation project investigating the potential of domestic flexibility to help operate the grid. 

Two types of domestic electricity flexibility service were trialled: ​

• Availability service: customers were paid to make their electric vehicles available to the grid by plugging in whenever they were at home.​
• Utilisation service: customers were paid to turn up or turn down their electricity usage during notified events.  ​
