Ofgem has launched a consultation on draft guidance on how electricity network owners, interconnector developers and offshore transmission developers can demonstrate wider long-term benefits from procurement decisions. The guidance covers long-term consumer value, whole-economy growth and net zero benefits, including reduced supply-chain risks, additional investment, improved productivity and lower greenhouse gas emissions. It aims to clarify how these benefits can be assessed within existing regulatory frameworks while maintaining consumer protection. Ofgem seeks views on whether the approach, evidence standards and examples are clear, practical and proportionate. The consultation closes on 5 January 2027.
