EDF is set to offer long-term nuclear power purchase agreements through a European-wide auction system, targeting major companies and choice supplier competitors. This announcement was made on Thursday, marking a critically important shift in how EDF approaches its commercial relationships.
New Commercial Policy
Since late 2023, EDF has implemented a new commercial policy focused on providing medium and long-term electricity contracts to large professional clients. This strategy aims to secure stable partnerships and provide predictability in a volatile energy market.
Negotiations with Electro-Intensive Industries
As part of this initiative, EDF has already engaged in bilateral negotiations with electro-intensive industries, such as metallurgy, glassmaking, and chemicals. The goal is to establish long-term partnership agreements tied to France’s past nuclear fleet, known as nuclear production allocation contracts (CAPN).

Initial Success with Industrial Partners
To date, EDF has signed nine letters of intent with major industrial players, representing an annual supply volume of 12 TWh. One of these has already resulted in a “contrat ferme” (firm contract), demonstrating the initial success of this approach.
Expanding the Offer: European Auctions
EDF is now looking to broaden its reach. According to a statement from EDF, “l’entreprise proposera à partir du premier semestre 2025 des contrats d’allocation de production nucléaire, pour livraison en France, à travers un mécanisme d’enchère à l’échelle européenne” (the company will offer, starting in the first half of 2025, nuclear production allocation contracts for delivery in France, through a European-wide auction mechanism).
Objectives of the Auction System
The primary objective remains consistent: to “réduire l’exposition des clients à la volatilité des prix sur les marchés de gros” (reduce customers’ exposure to price volatility in wholesale markets) while providing “plus de visibilité” (more visibility) for EDF to finance its substantial investments, notably in nuclear energy.
Target Clients for Nuclear Power Contracts
Specifically, the nuclear giant will launch a call for expressions of interest targeting two types of clients:
-
Companies of significant size across all sectors (industry, transport, tertiary, data centers) with electricity needs exceeding 7 GWh/year, located in France or Europe.
-
“Fournisseurs ou producteurs” (suppliers or producers) of electricity physically present in France, to supply their French or European clients.
Addressing Market Demands
Karine Revcolevschi, director of upstream-downstream optimization and trading at EDF, explained during a press briefing that “On répond à des demandes de fournisseurs alternatifs qui nous ont sollicité, de clients qui ne sont pas électro-intensifs” (We are responding to requests from alternative suppliers who have approached us, from clients who are not electro-intensive). This approach aims to “donner de la visibilité au système électrique pour accompagner l’électrification des usages” (provide visibility to the electrical system to support the electrification of uses), a key driver for decarbonizing energy.
Auction Details and Timeline
EDF plans to offer a volume of 10 TWh of electricity annually, with deliveries starting on January 1, 2026. The auction is expected to close around June.
Benefits of CAPN Contracts
According to EDF, these CAPNs “permettent aux partenaires de bénéficier d’une quote-part de la production effective du parc nucléaire historique moyennant un partage des coûts et des risques associés” (allow partners to benefit from a share of the effective production of the historical nuclear fleet, sharing the associated costs and risks). In other words, they benefit from a preferential tariff for 10 or 15 years, “reflétant les coûts du parc nucléaire et donc décorrélés des prix des marchés de gros” (reflecting the costs of the nuclear fleet and therefore uncorrelated with wholesale market prices), in exchange for taking on some risk related to the production of the operating nuclear fleet.
Replacing the Arenh System
These CAPN contracts,a commercial innovation from EDF,are designed to replace the current regulatory system (Arenh),which allows large industrial players and alternative suppliers to benefit from nuclear electricity at reduced prices. The Arenh mechanism is set to expire on December 31, 2025.
EDF’s Nuclear Output Increase in 2023
In related news, EDF reported a substantial increase in nuclear power output in France for 2023. The increase of 41.4 TWh brought the total to 320.4 TWh, which was at the higher end of their projected range. This “turnaround was achieved by good management of the stress corrosion repairs and reactor outages, thanks to efficiency and reactivity of the teams to improve the…”
Seeking Clients Outside France
As of March 6,2025,EDF is actively seeking clients outside of France for these long-term nuclear power contracts. This initiative, known as nuclear production allocation contracts (CAPN), comes as EDF faces challenges in securing long-term agreements with industrial users domestically.
EDF’s European Nuclear Power Auction: A extensive Guide
Introduction
EDF (Électricité de France) is launching a European-wide auction system for long-term nuclear power purchase agreements, marking a notable shift in its commercial strategy. This Q&A guide provides detailed insights into the auction, its objectives, and its implications for businesses and energy suppliers.
General Overview
What are EDF’s Nuclear Power Allocation Contracts (CAPN)?
Nuclear Production Allocation Contracts(CAPN) are long-term agreements offered by EDF that allow partners to share in the effective production of its past nuclear fleet,sharing associated costs and risks. They provide a preferential tariff for 10 to 15 years,reflecting the costs of the nuclear fleet,unrelated to wholesale market prices,in exchange for accepting production-related risks.
What are EDF’s objectives for the European nuclear power auction?
EDF has two main objectives:
Reduce customers’ exposure to volatile wholesale energy prices.
Provide EDF with more visibility to finance its investments, mainly in nuclear energy.
Why is EDF launching a European-wide auction for nuclear power contracts?
EDF aims to broaden its reach and respond to requests from option suppliers and non-electro- intensive clients, supporting the electrification of energy usage while securing more stable, long-term commercial relationships.
When will the CAPN contracts be available, and when will deliveries start?
Auction contracts will be available in the first half of 2025. Deliveries are expected to begin on January 1, 2026.
About auction mechanics
How much electricity will EDF offer through its European auction?
EDF plans to offer a volume of 10 TWh of electricity annually through the auction.
When is the auction expected to close?
The auction is expected to close around June of the auction year.
Target Clients
Who is eligible to participate in EDF’s European nuclear power auction?

CAPN vs. ARENH
What is the ARENH system, and how do CAPN contracts replace it?
ARENH (Accès Régulé à l’Énergie Nucléaire Historique) is the current regulatory system allowing large industrial players and alternative suppliers to benefit from nuclear electricity at reduced prices. CAPN contracts are designed to replace ARENH, which is set to expire on December 31, 2025.
What are the benefits of CAPN contracts compared to the ARENH system?
CAPN contracts offer stable, long-term price visibility, decoupling from the volatility of wholesale markets. ARENH is a regulatory system with a fixed expiration date, while CAPN offers longer-term partnerships based on shared costs and risks related to nuclear production.
What does the expiration of the ARENH System mean for energy buyers?
The expiration of ARENH means that large industrial players and alternative suppliers will no longer have guaranteed access to reduced-price nuclear electricity under the existing regulatory framework. This shift may require them to seek alternative supply agreements, such as CAPN contracts.
Benefits and Risks
What are the benefits of CAPN contracts for participating companies?
Participating companies benefit from:
Reduced exposure to volatile wholesale market prices
Preferential tariffs reflecting actual nuclear fleet costs
Stable, long-term energy supply for 10 to 15 years
Partnership with EDF, sharing in the benefits and risks of nuclear production.
What are the risks associated with CAPN contracts?
Participating companies share some production-related risks associated with the operating nuclear fleet.
What does ‘contrat ferme’ mean in the context of EDF contracts?
“Contrat ferme” (firm contract) signifies a legally binding agreement, indicating the accomplished conclusion of negotiations and the establishment of a concrete partnership between EDF and an industrial player. Securing a “contrat ferme” demonstrates the initial success of EDF’s commercial approach in securing stable, long-term agreements
