The National Grid System Operator view of a changing electricity system, and what this means for the role of flexible electricity. In particular, the opportunities this creates for energy managers to earn revenue/save costs from their flexibility. The lecture will offer an overview of the Power Responsive programme facilitated by National Grid which aims to support growth of participation from energy users, and how they could get involved.
