Load activity is related to the development of the electricity network to allow it to accommodate changes to electricity usage, the connection of new generation, the closure of power stations and ensuring that the network operates to the standards set by Ofgem which we are obliged to follow.

As we move into the RIIO-T2 period, the electricity network will need to adapt in many ways to facilitate the decarbonisation changes in the wider energy system.  We expect to see greater amounts of renewable generation connecting in the form of on-shore and off-shore wind farms, solar photovoltaics and a range of other technologies. We are also expecting the closure of the nuclear generation stations in our area over the next 12 years which will lead to many changes. 

The way that consumers use electricity is also changing as more customers use electric vehicles which will be dependent on the transmission network to move power around the country to link the available generation with the demands on the network.

Load related activity

Our RIIO-T2 Business Plan will set out the needs of the future transmission network to accommodate the transition to a low carbon energy system. Our plans 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 as low as possible for all end-users.

Consultations and Publications

As we develop our RIIO-T2 business plan, the energy landscape around us is continuing to change. In the last year we have seen an additional 139 MW of renewable generation connect to our transmission network and a 58% increase in the number of electric vehicles registered in our area. To ensure our T2 business plan is keeping pace with this change, we have updated our Future Energy Scenarios we use for Central and Southern Scotland to shape and test our RIIO-T2 investment plans:

This review of the possible future energy scenarios uses the most up to date national projections for generation and demands for electricity from the National Grid ESO 2019 Future Energy Scenarios. Our stakeholders also told us that they want us to be consistent with National Grid ESO’s scenarios because they know it ensures consistency with the approach used more widely across the energy sector.

At such a dynamic time in our energy system’s development, our RIIO-T2 plans are always designed with the flexibility to adapt to the different scenarios. Therefore, despite updating the scenarios we use in our modelling, our proposed T2 load-related expenditure hasn’t changed. This gives us further confidence in  how robust our overall approach has been for creating a plan that will set the pathway for Scotland moving to Net Zero by 2045.

This latest update to our Central & Southern Scotland Future Energy Scenarios document not only includes the energy-system changes we need to plan for, but also how these link through to our RIIO-T2 investment decisions. It also includes analysis on the demand and generation trends we have seen over the last few years and notably the rapid level of change we have already seen around us.

We would welcome any feedback on this document that you may have. Your views can be submitted to Our final RIIO-T2 business plan will be submitted to Ofgem on 9th  December 2019 , and we hope you take the opportunity to help shape our investment decisions for 2021 to 2026.
