UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

National Energy System Operator Limited (NESO) is exploring a strategic enterprise modelling capability solution for end-to-end modelling services. The requirement is for software, information systems, software-related services and data services. The intended capability would provide an enterprise technical platform for representing, managing and governing data, models, calculations, business concepts and relationships. It is expected to support energy data ontology and orchestration, source-to-decision auditability, scenario analysis, complex modelling, analytical transparency, decision support and AI-enabled innovation. The platform would integrate data, context, calculations, scenarios and business knowledge across NESO services, technology platforms and operational domains. Delivery would support NESO’s United Kingdom operations, including its critical national infrastructure environment, and would need to enable secure, resilient and highly available services.

This procurement is at the planning stage and is currently preliminary market engagement, rather than an invitation to tender. NESO expects interested suppliers to register through its iValua platform by 25 September 2026 to receive engagement information, complete questionnaires and submit clarifications. An online briefing is intended, with presentations possible if required. The engagement will inform the future scope, procurement strategy, implementation and transition model, operating model, commercial model, licensing approach and contractual arrangements. NESO may change the scope or structure, undertake further engagement or decide not to proceed. The anticipated contract has an initial five-year term from 1 August 2027 to 31 July 2032, with extension options in 12-month increments up to 31 July 2034. It is a utilities procurement under the Procurement Act 2023.

The engagement is likely to suit suppliers with mature enterprise modelling, data architecture, analytics and software platform capabilities, particularly those able to connect data, business context, calculations and scenarios across complex organisations. Relevant experience may include energy modelling and analytics, data ontologies, orchestration layers, lineage and auditability, interoperability, self-service tools, decision support and AI-enabled solutions. Suppliers should be prepared to demonstrate innovation, implementation and transition experience, operating-model options, replacement of existing services, licensing and commercial approaches, and management of dependencies and delivery risks. Strong candidates will understand data, analytical and technical standards and can provide secure, resilient and highly available services. Experience of working in critical national infrastructure or similarly controlled environments, with robust security governance and assurance, is likely to be important.
