HOW WE ARE REGULATED

RIIO-T2 2021 – 2026 

Ofgem announced in December 2020 its final determinations of our Gas business plan for the RIIO-T2 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.

Final determinations

Ofgem published its final determinations on Tuesday 8 December 2020.
