Our RIIO-2 business plan

Ofgem announced its final determinations of our Electricity Transmission business plan for the RIIO-2 regulatory period covering 2021 to 2026. Ofgem’s regulatory framework is known as RIIO (Revenue = Incentives + Innovation + Outputs). The RIIO model offers network companies incentives for innovation and securing investment, so they can develop sustainable energy networks at the lowest cost for current and future customers.
