What are the benefits of the RIIO-3 Framework?

• Improved network reliability and resilience. Upgrading ageing infrastructure, strengthening transmission and gas networks, improving safety, and reducing risks, like leaks, which over time should mean fewer outages and better service.  

• Support the UK’s transition to clean energy and net-zero goals by 2030 and 2050. The investments facilitated by RIIO-3 will enable more renewable energy generation to connect to the grid, better handle low-carbon energy, and support a more sustainable gas and electricity system.  

• RIIO 3 enables long-term cost savings and protection from future price shocks. By reducing “constraint costs, costs when the grid is overloaded or cannot handle supply, improving efficiency, and smoothing expenditure over time, RIIO-3 aims to lower some costs, making bills more stable and predictable.  

• For businesses, the RIIO-3 investments will also help strengthen productivity and resilience across the economy, helping energy-intensive industries, such as steelworks, cut their bills, potentially by 10 to 15%. Energy intensive industries, like steel works, could see bills around 10 to 15% lower than they would have been without RIIO-3 action, thanks to offsetting cost reductions from wholesale prices and government’s supercharger mechanism.  

The RIIO-3 framework seeks to balance current consumer costs with long-term public interest, safeguarding network resilience, enabling cleaner energy, and ensuring future generations also benefit.
