Raising awareness – current opportunities for storage Cost Savings Triad Avoidance Red Zone Management Revenue Potential Frequency Response (1-30 sec) Reserve (2 mins – 4 hours) Stand alone Capacity Market (4 hours) Maximise renewable generation Electric vehicles Enhance flexibility of existing assets Store cheaper energy imported Co-located with DSR or renewables

Evolving flexibility markets – future opportunities for storage National Grid product strategy ‘Whole system’ approach across T-D interface SNAPS document outlines ambition to make system needs more transparent & services accessible and fit for the future Considers route to market for: Fast acting response Accessing flexibility we need closer to real time ENA’s Commercial Principles paper considers how SO and DNOs procure flexibility from distributed resources Innovation projects signpost potential future revenue streams: Power Potential – NG & UKPN Demand Turn Up – NG & WPD

Building on the foundations for the Future We are operating the future electricity system today New system challenges bring opportunities for storage Progress is being made and it’s important to keep momentum
