Independent Cost Assessment of Large Nuclear New Build Projects

The Challenge

To evaluate the feasibility of launching a fleet of large-scale nuclear new build projects, the client required a robust and independent cost basis. Without vendor engagement at this early stage, the challenge was to establish credible, transparent cost estimates that could support strategic decision-making and build internal alignment. The objective was to assess the relevance of pursuing such a program with confidence, grounded in realistic financial assumptions.

The Solution

Tractebel conducted a comprehensive techno-economic analysis, developing cost estimates from scratch for a fleet deployment scenario. The mission included defining a detailed Code of Accounts, collecting and harmonizing cost data from international benchmarked nuclear projects, and adapting proven methodologies to the client’s specific ecosystem. Tractebel also assessed supply chain localization potential and integrated lessons learned from its global nuclear project portfolio, ensuring the estimates reflected both industry best practices and contextual realities.

The Impact

The result was a systematic cost categorization and deep analysis that provided the client with a solid foundation for strategic planning. Tractebel’s independent review increased confidence in the financial framework, enabling the program to move forward with clarity and credibility. This mission exemplifies Tractebel’s role as a trusted advisor in complex energy infrastructure, supporting clients in making informed decisions at the earliest and most critical stages of project development.
