    "riskDetails": "Key risks to the successful delivery of the contract include:\n• Availability and retention of suitably skilled and experienced resources over the contract period;\n• Conflicts of interest arising from suppliers' wider market activities and relationships with Transmission Owners or their supply chains;\n• The variable and evolving nature of the scope of work across RIIO‑3, including changes in project eligibility, volume and timing;\n• Dependence on timely provision of information and cooperation from third parties, including Transmission Owners; and\n• The complexity and scale of electricity transmission projects, which may impact delivery timelines and assurance activities.\nThese risks will be managed through contractual controls, governance arrangements, reporting requirements and performance management mechanisms as set out in the framework and call‑off contracts.",

Call‑off contracts will be awarded in accordance with the framework agreement and applicable public procurement legislation.\nPrices will be based on the daily rates submitted by suppliers as part of their tender and evaluated at framework award stage. Call‑off contracts will be awarded in accordance with the framework agreement, either by direct award or following a further competition, with pricing determined by the applicable framework rates and the requirements of the individual call‑off. ",
        "periodRationale": "Ofgem are looking to operate a Framework Agreement that will have a duration of five years as opposed to four, with the later typical under the Procurement Act 2023. Given the nature of the services required of the ITA means that a longer term is required. This is because aligning closely with the RIIO-3 price control term length (eg RIIO-3 April 2026-March 2031) offers practical benefits to the services being provided by the ITA, primarily, improved clarity to relevant stakeholders regarding what can be expected across the entire price control.

The ITA will be an independent body responsible for providing assurance to Ofgem on the design, procurement, cost and overall delivery of selected load‑related projects across all electricity Transmission Owners (TOs). The objective of ITA assurance is to support enhanced and accelerated regulatory decision‑making and processes.\nFurther information can be found in the attached ITT document.",
    "riskDetails": "Key risks to the successful delivery of the contract include:\n• Availability and retention of suitably skilled and experienced resources over the contract period;\n• Conflicts of interest arising from suppliers’ wider market activities and relationships with Transmission Owners or their supply chains;\n• The variable and evolving nature of the scope of work across RIIO‑3, including changes in project eligibility, volume and timing;\n• Dependence on timely provision of information and cooperation from third parties, including Transmission Owners; and\n• The complexity and scale of electricity transmission projects, which may impact delivery timelines and assurance activities.\nThese risks will be managed through contractual controls, governance arrangements, reporting requirements and performance management mechanisms as set out in the framework and call‑off contracts.",
