There is a risk that these factors will continue to impact construction progress and the supply chain. Action plans are underway to address delays and improve the performance of civil engineering and electromechanical assembly. Compliance with the schedule and cost to completion (see section 1.4.5.1.2.5 “United Kingdom – New Nuclear Division”) requires that these actions produce the expected results. However, in this context, risks to the schedule and costs to completion increased in 2021. They are now very high.
The IRR of the HPC project is sensitive to:
Due to the difficulties encountered by the project, notably on civil performance and marine works, and the increase in risks such as the Ukrainian conflict, Brexit, COVID, supply chain disruption and inflation, a new comprehensive review to update the costs and schedule estimates announced in January 2021(1) is underway and is expected to be finalised by summer 2022.
On 25 January 2019, the French government published the main guidelines of the Multi-year Energy Programme adopted by a decree of 21 April 2020. The sector contract signed on 28 January 2019 by the French government and the French Nuclear Sector Strategic Committee (CSFN) includes a section on the preparation of the industrial capacity necessary for the execution of a construction programme for new reactors in France.
In accordance with these orientations, the government has asked EDF to prepare a comprehensive file with the nuclear industry by mid-2021 relating to a programme for the renewal of nuclear facilities in France. EDF, along with the nuclear industry, submitted to the French State, in May 2021, a dossier of economic and industrial proposals for the launch of a new reactor programme in France. This dossier, based on EPR2 technology, details what the regulatory and financing framework for such a programme could be. It is based on the implementation of a programme of three pairs of EPR 2 successively at Penly, Gravelines and a third riverside site in the Auvergne Rhône Alpes region (Bugey or Tricastin), while continuing the feasibility analysis on other nuclear sites.
This offer was subject to an audit in the summer of 2021 commissioned by the French General Directorate for Energy and Climate (DGEC), which validated the methodology used to estimate the schedule and costs.
In addition, on 25 October 2021, RTE made public its study “Futurs énergétiques 2050” (Energy Future 2050), which analyses possible changes in electricity consumption in France and lays out six electricity mix scenarios to achieve carbon neutrality by 2050. The study clearly indicates that an electricity mix with a significant nuclear base is preferable to other scenarios.
The main challenge now is therefore to ensure that the conditions for a decision to launch the programme and its transposition into the legal and financial framework necessary for its implementation are brought about as soon as possible.
This requires three main prior actions:
In order to bring about the conditions for a commitment decision, EDF is now working with the public authorities on several points, in particular:
A description of the Sizewell C project development in 2021 is provided in section 1.4.5.1.2.5. EDF’s ability to make the final investment decision alongside other investors and to contribute to the financing of the construction phase is contingent on, inter alia:
Thus, the project is pursuing its strategy of replicating the HPC design as widely as possible, especially with suppliers, and of using the lessons learned from HPC.
Failure to bring about these conditions could result in the Group not making a final investment decision.
The main control actions to create favourable conditions for the decision include :
EDF and its partners submitted a comprehensive conditional non-binding bid to NPCIL at the end of 2018; in this offer, the EDF group and its partners undertake to supply all the studies and equipment for the nuclear island, the conventional island, the auxiliary systems, as well as the heat sinks and galleries of the EPR technology.
EDF does not plan to invest in the project, and the NPCIL client will be the overall project manager and integrator in the implementation phase (bearing in particular the risks of licensing, construction, assembly and overall integration). In April 2021, a binding technical and commercial offer was transmitted and discussions are ongoing. (See section 1.4.1.1.3.2 “Other New Nuclear projects” and section 1.4.5.3.6.2 “Southeast and Southern Asia”).
The project has the risk profile of a supplier of engineering services and equipment supplies; its value therefore lies in the realisation of the margin included in the price of the services sold. Like all large complex industrial projects, this project presents technical, industrial and cost control risks for the scope under the responsibility of EDF and its partners, as well as a risk relating to compliance with pre-defined milestones, particularly with regard to the expected revenue model. In addition to the country risk, which includes a substantial tax dimension, the conditions related to the nuclear liability framework in India and the securing of the project’s financing plan must be resolved before the final contracts are signed.
