ISG Terms of reference
Independent Stakeholder Group
Terms of Reference - June 2025
1. Background
1.1. Throughout RIIO-ED1, Electricity North West (ENWL) has operated a number of stakeholder advisory panels and forums, which have contributed scrutiny of ENWL’s ED1 business plan commitments and provided input into the development of its business plan for RIIO-ED2. In addition, ENWL also received scrutiny and challenge throughout the development of its ED2 business plan from its independent Customer Engagement Group (CEG), which was established to ensure that the final plan reflected the needs and preferences of consumers.
1.2. To ensure that the customer voice continues to be heard over the duration of the RIIO-ED2 price control, ENWL refreshed its stakeholder advisory panel structure and established an Independent Oversight Group (IOG) to provide additional assurance of customer and stakeholder engagement in decision-making and to review ENWL’s performance against its business plan commitments as far as they pertain to stakeholders and customers.
1.3. The ENWL Independent Oversight Group (“IOG”) was a panel of independent individuals, with an independent Chair together with members representing each of the six advisory panels that ENWL has established to ensure ongoing stakeholder and customer input into its decision-making processes in important work areas.
1.4. The RIIO-ED3 Business Planning process has formally mandated the establishment of an Independent Stakeholder Group (ISG) to challenge and scrutinise network companies’ business plans and performance throughout RIIO-ED3. ENWL has therefore transitioned its IOG into the required ISG.
