EDF UK, in partnership with Capgemini, has launched a major digital engineering transformation to support its nuclear power station projects. At the core of this initiative is a shift from traditional document-centric processes to a data-centric engineering model, enabled by an Integration Centre of Excellence (ICoE) built on MuleSoft technology. This approach aims to unify data across teams, reduce project delays, and accelerate time-to-market for nuclear construction and commissioning efforts.
Digital Engineering at Scale
EDF’s New Nuclear Build Generation Company (NNB GenCo) is responsible for delivering large-scale nuclear power stations such as Hinkley Point C and Sizewell C. Historically, engineering teams have relied on document-based workflows, which can lead to duplication, versioning issues, and inefficiencies in data access. Capgemini’s solution replaces these outdated systems with a connected digital ecosystem that centralises data, enhances traceability, and facilitates better decision-making.
With the implementation of MuleSoft and the establishment of the ICoE, EDF has automated over 50 integration flows. This integration layer connects over a dozen systems, supporting a wide range of use cases across engineering, compliance, and delivery. The result is a more agile and scalable platform that empowers EDF’s teams to collaborate more effectively and respond more quickly to evolving requirements.
Delivering Measurable Impact
The partnership has already produced substantial benefits. EDF reports a 40 percent reduction in project delays and a 30 percent improvement in time-to-market for key project milestones. These outcomes are not just technological wins; they also have operational significance, supporting faster, more efficient delivery of critical energy infrastructure.
Capgemini’s approach included user-centred design, agile delivery methods, and deep collaboration with EDF’s internal stakeholders. The use of reusable APIs, consistent integration patterns, and a governance framework ensures the solution is sustainable and future-ready.
Why It Matters to Technology Leaders
This collaboration offers a compelling blueprint for how enterprise technology leaders can modernise legacy engineering and infrastructure environments. Rather than ripping and replacing core systems, Capgemini and EDF used a platform-based integration strategy to create a seamless, data-rich environment that spans business functions and technology stacks.
For CIOs, CTOs, and heads of IT strategy, the message is clear: building digital resilience and operational efficiency does not always require a complete system overhaul. Instead, success lies in orchestrating existing tools through modern integration frameworks that prioritise flexibility, scalability, and usability.
In industries like energy, where regulation, safety, and long-term planning dominate, the ability to maintain control while improving speed is critical. The ICoE model demonstrates how organisations can adopt agile practices without compromising on governance or security. It also shows how digital transformation is no longer confined to front-office experiences—it is equally relevant to complex, regulated environments like nuclear power.
Closing Insights
EDF’s partnership with Capgemini exemplifies how digital integration can transform even the most complex engineering programmes. By shifting to a data-centric model and investing in enterprise-grade integration architecture, EDF is not only improving project efficiency but also building the foundations for a more agile and scalable future. Technology leaders in infrastructure-heavy sectors should take note: smart integration, when executed with discipline and strategic clarity, delivers tangible returns.
