  • 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%

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
  • The Low Carbon Hub
  • Oxfordshire County Council
  • Oxford City Council
  • Open Utility
  • Origami Energy
  • EDF Energy
  • Nuvve
