RIIO T2 Energy Scenarios Consultation

Planning for the Transmission network of the future

We are currently developing our 2021-2026 investment plan for the transmission network in advance of submission to Ofgem as part of the RIIO T2 process in 2019. Over the next decade we expect to see major changes to the way the transmission network operates in response to the significant challenges facing the energy industry. So your views, as our stakeholders, are vital to help us shape our futureplans.

Our RIIO-T2 investment plan will set out the needs of the future transmission network to accommodate the transition to a low carbon energy system. Our plans will seek to accommodate the needs of all supply and demand customers, help facilitate overarching decarbonisation objectives and target investments only where needed to keep costs low for end-users.

Our future plans need to consider the changes that may arise. To do this, we are using a scenario based approach to help understand the future evolution of energy supply and demand on our network through RIIO-T2 and beyond. The SPT scenarios use the four National Grid 2018 Future Energy Scenarios as the starting point, running from 2017 to 2040. The Future Energy Scenarios are intended to identify a range of credible scenarios across gas and electricity on a GB-wide basis. They are developed through extensive engagement with stakeholders and are widely recognised as being a reference point.

We are looking for stakeholder feedback on these scenarios and our approach.

We are keen to hear your views on these scenarios so please send your response before the closing date of 28th September 2018 to by the closing date of 28th September 2018.

Within the RIIO T2 Energy Scenarios document we have outlined a number of questions and will be holding a webinar to discuss these further on the 20th September. If you would like to join this webinar, please contact
