The changing role of electrical networks and why it matters to you. • Stewart Reid - Head of Future Networks

Networks … 2

Real progress on decarbonisation since 2008 Climate Change Act • GB Power sector emissions intensity down 50% since 2008. • 33% of power from Renewables vs 5% in 2008. • Energy networks are a high performing success story, playing a key role in decarbonisation: • Since 1990 the networks have invested £100billion and costs have fallen by 17% • Power cuts are at their lowest level ever with a 59% reduction since 1990. • We’ve accommodated the rapid rise in renewables with 28GW of local generation connected • SSEN alone has connected enough renewables electricity to power 4million homes. • Customer satisfaction in networks, recorded by Ofgem, is over 80% 3

New Markets Peer to Peer trading across the network 18

New ways to buy and trade energy Local Generation New Value streams 19

“Must work for all customers” • Penalise those that cannot use demand flexibly • Reward those that have flexible demand • Create opportunities for gaming • Stimulate markets • Minimise the resilience of the network • Maximise the utilisation of the network • Digitise the Energy System • Increase system interdependencies • Enable Community energy trading • Penalise those that don’t belong to communities • Remove the energy universal service obligation • User pays • Generate duplication • Promote competition between DNOs 20

& Project LEO Local Energy Oxfordshire

TRANSITION in Oxfordshire TRANSITION proposes to deliver a trial in Oxfordshire, coordinating with Project LEO (Local Energy Oxfordshire) to enhance overall learning value. Project LEO provides a £40m programme. The requested £13m Innovate UK grant funding is matched by £27m private sector funding, and further leveraged by £46m public sector investment. Project LEO will be led by SSEN and delivered with the following varied and active partners: • University of Oxford • • Oxford Brookes University Open Utility • The Low Carbon Hub • Origami Energy • Oxfordshire County Council • EDF Energy • Oxford City Council • Nuvve 22

Why it matters to you? New Opportunities opportunities to to connect for sell flexibility less and quicker. Opportunities Opportunities to trade energy to buy energy in locally. new ways. 23
