British regulator publishes final determination on revenues for the electricity distribution utilities
British energy regulator Ofgem published Final Determinations under its RIIO-ED2 performance-based regulation arrangements, which cover Great Britain’s 14 distribution network operators (DNOs). Under its decision, Ofgem is allowing £22.2 billion (US$26.6 billion) of expenditure for investment through 2028. This represents a 12% cut in the expenditure the DNOs proposed in their draft business plans. However, it represents a substantial increase, 17%, in the average expenditure compared to the present revenue period.
The package contains a strong commitment to reduce the number and duration of interruptions, with ongoing incentives to improve network reliability through a combination of incentives and guaranteed standards. Further, there is an enhanced focus on resilience, with the companies expected to prioritize spending on resilience for severe weather events.
Regulator launches review of network companies’ revenue-setting process – Ofgem published an Open Letter seeking views on the framework it uses to set the revenues for electricity and gas network companies. The consultation is aimed at identifying whether it moves away from the existing performance-based RIIO (Revenue = Incentives + Innovation + Outputs) framework it has used since 2013. The review was prompted by the scale and range of challenges facing those networks that include threats from climate change; substantial shifts in energy supply and demand; and opportunities offered by the energy transition, including taking advantage of improved data and digitalization. Among the alternative models suggested in the open letter were an alternative ex-ante incentive regime; an ex-post regime with allowances set based on a predetermined rate of return; or a model involving greater stakeholder participation, including through negotiated settlements.
The deadline for submissions ended in October, with plans for a further, more detailed consultation in early 2023.
