CRE

The Commission de régulation de l'énergie (CRE) is France's independent energy regulator, established by the 2000 electricity sector liberalisation law. CRE oversees transmission and distribution networks for electricity and gas, sets network access tariffs (TURPE for electricity, ATRT for gas), manages capacity auctions, and enforces market transparency rules under European REMIT obligations. In the current European energy markets context, CRE is at the centre of French nuclear pricing: on 14 April 2026, CRE set the average sale price for French nuclear output under the VNU mechanism (Vente du Nucléaire Unique, which replaced the ARENH mechanism) at EUR 65.90/MWh. This is the reference price against which EDF's forecast 350-370 TWh of 2026 nuclear output is benchmarked.

The VNU mechanism determines how France monetises its nuclear surplus into the wholesale market. With TTF trading at EUR 42.26/MWh on 15 April, the EUR 65.90 VNU floor means French nuclear electricity is priced well above the gas-linked power price in Germany and much of northern Europe. That premium supports EDF's revenue floor but also creates a strategic question: if TTF remains below EUR 55-60, French nuclear surplus is better stored or curtailed than sold at a discount. The timing matters because Flamanville-3 enters a one-year Major overhaul in September 2026, removing 1.6 GW from the supply stack at the point when injection-season savings from nuclear exports are most needed for autumn rebalancing.

CRE's VNU price-setting is not a discretionary call. The regulator applies a statutory formula reflecting long-run marginal cost, capacity charges, and the cost of capital for new nuclear. The practical effect is that CRE's number anchors the floor of French electricity market pricing for the year, and with Flamanville-3 offline from September, the autumn supply hole opens exactly when the CRE benchmark loses its largest single unit of backing generation.
