National Grid manages a portfolio of major transmission infrastructure projects across onshore and offshore programmes. As the scale and complexity of delivery increases, National Grid requires a more integrated and digitally enabled approach to project controls, governance and performance management. The initial phase of the requirement will support the Onshore GGP programme, with the potential to extend to additional delivery programmes and operating models in the future. National Grid is seeking an Integrated Project Management Office (IPMO) capability that provides a consolidated view of project and portfolio performance information across areas such as cost, schedule, risk, commercial management, change management and baseline control. The objective is to improve visibility, assurance and decision-making while reducing reliance on manual and fragmented processes. As part of this requirement, National Grid is seeking a digital solution that supports project controls, commercial, finance, PMO and leadership teams through the integration of data and processes across existing business systems and reporting platforms. The solution is expected to support integrated project controls activities including baseline management, change control, forecasting, contingency management, cost management, cost-value reconciliation and payment management. It should provide auditable workflows, role-based access controls and portfolio-level reporting, while supporting alignment between cost and schedule information through standardised project control structures. National Grid requires a scalable and flexible solution capable of supporting current requirements while providing a foundation for future enhancements in project controls, reporting and analytics capabilities. The solution must integrate with approved National Grid systems and data sources, while ensuring National Grid retains ownership and control of its data. The solution should support appropriate governance, data quality controls, metadata management, historical data retention, multi-currency capability and role-based access management. National Grid is seeking a solution that can evolve over time as business requirements mature and adoption increases, supporting improved portfolio transparency, consistent project controls processes and effective collaboration across multiple delivery programmes and delivery partners.
