3. +44 (0)1225 820980 ©BMT Hi-Q Sigma Ltd  EDF Nuclear Generation are the licensed operators of a Fleet of 7 Advanced Gas-cooled Reactors (AGRs)  With a range of Plant Life Extensions (PLEX) campaigns, the fleet is planned to be retired between 2025 and 2035  Lifetime Programmes are an organisation within EDF responsible for delivering a range of strategic programmes to ensure safe, cost-effective operation of the fleet for its remaining life  Carbon Deposition is one such cross-cutting lifetime programme; aimed at mitigating the effects of carbon build-up on the reactor fuel and auxiliary systems  The Carbon Deposition programme comprised 5 workstreams: Prevent; Remove; Harden; Understand; and Manage  BMT HQS were originally tasked by EDF to help deliver the major project under the ‘Prevent’ workstream called Deposition Resistant Fuel (DRF)  The DRF project was approaching its major investment decision point and our tasking was extended to cover development of a benefits model and realisation plan for this project Background

Problem and solution space bounded. Baseline ‘As-is’ performance agreed Causal relationships between candidate change projects & programmes, outcomes, & benefits agreed. Scale of benefits estimated. Interdependencies between changes characterised Time-phased profiles of benefits showing quantified baseline & target levels in financial & non-financial terms. Balance of investment options appraised. Benefits prioritised, appropriate tracking measures selected & assigned to BCMs. Plan to realise benefits & mitigate blockers. BCMs monitor & report via PMO / PfMO

12. +44 (0)1225 820980 ©BMT Hi-Q Sigma Ltd An Unexpected Journey: from Project to Programme to Portfolio and Back Again Plan Benefits Realisation Understand & Model the System Identify & Map the Benefits Developed a logical system model to capture the complex interactions between the problem (Carbon Deposition) and the impacts of this on the system Developed a logical benefits map which helped EDF to gain an understanding of how to manage its whole portfolio as opposed to stand-alone projects and programmes Developed a benefits profiling tool combined with cost modelling work to enable a ‘complete package’ of cost-benefit analysis for a range of assumptions, what-if scenarios. Working with a wide group of stakeholders added robustness to the decision making process Value & Profile the Benefits Development of KPIs for ongoing management of Carbon Deposition This analysis enabled EDF to prioritise their investment across the portfolio and take a conscious strategic decision of alternative action to invest based on maximising safety and financial benefits

You therefore need to understand risk and uncertainty and model in your estimates including sensitivity (what-if) analysis to test key assumptions  Presentation of results must support decisions: Investment Appraisals and Business Cases; Discounted Cash Flows;  There should be a parity of rigour in developing cost and benefits, as well as shared data, assumptions, risks, etc. key lessonsEDF Case Study
