National Grid plc (NGG) has filed a Form 6-K disclosing Ofgem’s Draft Determination for the RIIO-ET3 price-control period covering April 2026–March 2031. The draft relates to National Grid Electricity Transmission (NGET) and follows the company’s final business plan submission in December 2024. Ofgem continues to acknowledge the need for "significant levels of investment" in the UK transmission network and has proposed allowance decisions for a subset of projects; the remainder will be assessed through in-period mechanisms.
National Grid reiterates its intention to deploy around £60 billion of group-wide capital expenditure between now and March 2029, underscoring the scale of network expansion required to meet rising electrification and decarbonisation targets. Management will scrutinise the draft package to determine whether it offers an "investable" financial framework, highlighting that further progress on incentive mechanisms is still required to balance consumer value with shareholder returns.
The company will engage with Ofgem through the consultation phase leading to a Final Determination expected in December 2025. Securing an attractive allowed return, incentive upside and timely cost recovery will be critical to funding the planned investments while preserving credit metrics and dividend capacity. The filing contains extensive forward-looking-statement disclaimers but no new earnings guidance.
