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.",

"description": "The framework will operate on a call-off basis for the duration of the framework term.

Prices 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."

"financialTerms": "Payment will be made in accordance with the framework agreement and applicable call-off contracts. Charges shall be based on the agreed daily rates submitted by the supplier at tender stage and applied in line with the requirements of the relevant call-off. Payment will be subject to the satisfactory delivery of services and submission of valid invoices in accordance with the contract terms. Further details of invoicing, payment timing and any reporting requirements are set out in the framework and call-off contract documentation."
},
"riskDetails": "Key risks to the successful delivery of the contract include: * Availability and retention of suitably skilled and experienced resources over the contract period; * Conflicts of interest arising from suppliers' wider market activities and relationships with Transmission Owners or their supply chains; * The variable and evolving nature of the scope of work across RIIO-3, including changes in project eligibility, volume and timing; * Dependence on timely provision of information and cooperation from third parties, including Transmission Owners; and * The complexity and scale of electricity transmission projects, which may impact delivery timelines and assurance activities. These 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.",
