What is an EDF OA purchase agreement?

The photovoltaic electricity purchase agreement, commonly called the EDF OA contract (Purchase Obligation), is the commitment by which EDF Obligation d'Achat (EDF subsidiary, mandatory buyer designated by the State) undertakes to purchase for 20 years all or part of the electricity produced by a photovoltaic installation, at a guaranteed and indexed rate. Three main models: total sales (all production is sold), surplus sales (self-consumption + surplus resale), collective self-consumption (Decree No. 2017-676 of April 28, 2017, distribution among consumers within a 2 km radius — exemption up to 20 km in rural areas). The purchase rate is fixed by the Rate Order in effect on the date of complete connection application (H2 2026 for new contracts in the second half of 2026).

Why sign the EDF OA purchase agreement electronically?

Accepted by EDF OA since 2019

EDF OA has accepted photovoltaic purchase agreements signed with advanced signature (AES) eIDAS via its EDF OA Solar portal since 2019. Article 1366 of the Civil Code guarantees the same evidentiary value as a handwritten signature, essential for a 20-year commitment.

Three-party: owner + installer + EDF OA

The OA contract involves three parties: owner (producer), RGE QualiPV installer (often acting as representative for the procedure), EDF OA (buyer). Our multi-signer workflow manages sequential or parallel signing with individual SMS OTP and qualified timestamping.

20-year archival aligned with OA contract duration

The OA contract has a duration of 20 years (Rate Order). Certyneo archives the contract + eIDAS audit trail for 10 years (minimum legal duration) with possible contractual extension to cover the entire OA contract duration + 5 years after expiry.

Enforceable eIDAS audit trail

Each OA contract is delivered with a proof PDF: identity of signatories (producer + EDF OA + installer), qualified timestamp, SHA-256 hash, IP geolocation, SMS OTP verification. Enforceable against EDF OA in case of dispute over tariff conditions.

Sign an EDF OA purchase agreement in 4 steps

From Consuel to EDF OA service activation, the contract secures the chain in less than 5 minutes.

  1. 1. Prepare the OA contract

    Upload the EDF OA template generated from the EDF OA Solar portal after Consuel service activation: producer + RGE QualiPV installer identity, peak power, type (total sales, surplus, collective self-consumption), applicable rate (H2 2026).

  2. 2. Add signatories

    Producer (owner) + EDF OA representative + installer (if applicable). For collective self-consumption, add the PMO and list of consumers. Each receives a secure link by email with SMS OTP.

  3. 3. Choose the eIDAS level

    AES (advanced) de facto mandatory for a 20-year commitment: SMS OTP, unique certificate per signatory, qualified timestamp, SHA-256 hash. Presumption of reliability under Article 1367 of the Civil Code.

  4. 4. Sign and activate on EDF OA Solar

    Each signatory signs from their phone. The finalized contract is attached to the file on the EDF OA Solar portal and triggers the start of the OA contract on the Consuel service date.

Frequently asked questions

Can the EDF OA photovoltaic contract be signed electronically?
Yes, without restriction since 2019 via the EDF OA Solar portal. The Energy Code does not impose any particular form for the OA contract. The advanced eIDAS signature benefits from the presumption of reliability of Article 1367 of the Civil Code — essential for a 20-year commitment.
What is the photovoltaic purchase price in 2026?
The tariff is set by Tariff Order S2 2026 (second half of 2026), published quarterly by the CRE (Energy Regulatory Commission). For installations ≤ 100 kWc in total sale, approximately 10-13 c€/kWh depending on capacity. For surplus sale with self-consumption, investment grant + surplus purchase tariff. Tariff guaranteed and indexed for 20 years.
Total sale, surplus sale, collective self-consumption: what is the difference?
Total sale = 100% of production sold to EDF OA, injection-only connection. Surplus sale = self-consumption + surplus resale to EDF OA, withdrawal and injection connection. Collective self-consumption (Decree 2017-676) = production shared between consumers within a 2 km radius (20 km in rural areas) via a PMO.
What is the duration of the EDF OA contract?
20 years since the 2017 Tariff Order for rooftop photovoltaic. The contract begins on the service date certified by Consuel. At expiration, possibility of extension at market rate or switching to another buyer (aggregator, alternative supplier).
What documents does EDF OA request with the contract?
Consuel Certificate (AC visa or Green Visa), RGE QualiPV certificate from the installer, proof of ownership or lease with authorization, single-line diagram, site plan, quote and paid invoice, Enedis connection contract (CRAE). For collective self-consumption: PMO agreement + list of participants.
Is the photovoltaic purchase tariff indexed?
Yes, the purchase tariff is indexed to the INSEE index of industrial product prices (IPP) for the "production and distribution of electricity" sector. Indexation is annual, on the contract anniversary date. Provides protection against inflation over 20 years.
Can the OA contract be terminated before 20 years?
Yes but with constraints. Producer side: termination possible with 1 year notice + penalty (prorated according to length of service). EDF OA side: termination only in case of material breach (fraud, persistent technical non-compliance). In practice, the contract runs to term in 95% of cases.
What happens at the end of 20 years?
At expiration, the OA contract ends. The producer can: (1) extend at market rate with EDF OA, (2) sign a new contract with an alternative supplier or aggregator, (3) switch to 100% self-consumption. The continuity of the Enedis connection is guaranteed; only the purchase contract changes.
