What this stakeholder priority is about

This priority is about how we help the UK achieve net zero targets by innovating to advance the decarbonisation of electricity supply, transport and heat at the lowest cost to consumers.

We do this by:

  • innovating in the reinforcement of the electricity transmission network
  • enabling competition in networks and non-network solutions
  • collaborating across organisational boundaries to enable whole system solutions
  • proposing options that enable the decarbonisation of power, transport and heat
  • proposing uncertainty mechanisms that ensure our plan can flex to deliver net-zero.
