On 9 July 2020, Ofgem published its Draft Determinations for the RIIO-T2 period, setting out its first formal response to our Business Plan for the next price control period, which was subject to a period of public consultation.

In a detailed and evidence-based submission, which outlines clear and workable solutions throughout, we have urged Ofgem to reconsider the swathing and unjust cuts it has proposed to our stakeholder-led investment plans.  These cuts put at risk the delivery of net zero emissions, network reliability and security of supply, and jeopardise job creation plans.

We remain optimistic that Ofgem has been listening to stakeholder perspectives since its draft determination.  Given the scale of issues raised, we have asked Ofgem to consider an interim update before the publication of final determinations in December.

You can find our consultation response and supporting evidence below.
