EDF Board Commits €2.7bn to EPR2 Fabrication With Year-End Investment Decision in Sight
EDF has approved manufacturing funds for France's planned six-reactor nuclear build, targeting a final investment decision by December despite an active EC state aid investigation.
EDF's board of directors approved a €2.7bn manufacturing budget for its EPR2 reactor programme in 2026, according to the utility's annual results, targeting a final investment decision by year-end on a six-reactor build that EDF now forecasts will cost €72.8bn. The approval covers early manufacturing of main components, including reactor pressure vessels, as the utility moves from design into fabrication for the first units.3
France's nuclear fleet has direct implications for European power and gas markets. When French reactors fall short of full output, gas-fired generation covers the gap and continental hub prices reflect the shortfall. Remit data showed EDF curtailing 3 GW of output, equal to 4.6% of French installed nuclear capacity, on Wednesday (2026-07-08) during a 42-degree Celsius heatwave, Montel reported. ICE Endex TTF front-month settled at €68.31/MWh on Monday (2026-08-24), up 3.77% on the session.6
The European Commission launched an investigation on Tuesday (2026-05-19) into France's plan to subsidise the construction and operation of six new reactors with a combined capacity of 10 GW, Montel reported. The probe covers both the build and operational phases of the support scheme. The project carries a cost estimate of EUR 73bn in 2020 euros.1
The programme is structured as three pairs of EPR2 units, each reactor rated at 1.7 GW. But the financing mechanism underpinning construction has not cleared Brussels. France's economy and energy ministry told Montel that negotiations with the Commission would continue for "the coming months," a timetable that runs directly into EDF's end-2026 FID target. The ministry committed to providing the EC with "all the additional information relevant" to the inquiry.2,1
EDF's own annual results put the forecasted cost at €72.8bn, aligning with the EUR 73bn figure expressed in 2020 euros that the ministry cited in its EC submissions. The board's approval of manufacturing funds reflects an intention to advance procurement ahead of a formal FID, while the company also committed to submitting a detailed proposal on manufacturing contracts for the reactor's nuclear section. Brussels has given no timeline for completing its state aid review.3,2
EDF's record on nuclear new-build provides relevant background. The Flamanville 3 reactor, France's first EPR and the direct precursor to the EPR2 design, saw its outage extended by at least a further week in April 2025 (2025-04-04) for maintenance on three additional components in the nuclear section, Reuters reported, after a two-month delay had already deferred its return to service. The EPR2 programme shares technical lineage with Flamanville 3, whose construction costs and schedule ran well past initial targets.5
EDF is also building out smaller-scale, faster-deployable storage. The utility's renewables subsidiary announced on Thursday (2026-06-11) a portfolio of 1 GW of battery storage projects in France, Montel reported. EDF Power Solutions storage coordinator Catherine Bourg said the projects would be mainly co-located with existing wind and solar farms, with 100 MW expected to break ground this year and 170 MW next year. EDF also commissioned its first battery in mainland France at a capacity of 20 MW.4
The pace of EC proceedings is the key variable for EDF's FID timeline. The ministry's "coming months" framing implies Brussels will not wrap its review before December 2026. If it does not, EDF faces a concrete choice: hold the FID until state aid is formally cleared, or advance manufacturing commitments using its own balance sheet before any government support mechanism is locked in.2,1
