What is a Corporate PPA?
A direct purchase agreement for competitive and predictable energy.
A Corporate PPA (Power Purchase Agreement) is a long-term electricity purchase contract concluded directly between a renewable energy producer and a corporate consumer. This contract is typically backed by a specific production asset—such as a solar or wind farm—whose electricity is delivered with its guarantees of origin.
Unlike a traditional supply contract, a PPA offers a price that is decoupled from wholesale market fluctuations and instead linked to actual production costs. The result: unmatched budget visibility over 5 to 20 years, and truly green, traceable, and competitive electricity.
In France, the first Corporate PPAs emerged in 2019. Since then, the market has experienced strong growth, driven by energy price volatility and the end of the ARENH mechanism in late 2025, which is pushing large consumers to secure their supply through direct contracts.
Key features of the solution
A bespoke contract, tailored to your needs.
Each Corporate PPA is tailored to your consumption profile and objectives. Mexens offers a range of contract options to meet your specific needs.
PPA « Pay-as-Produced »
You purchase electricity generated from renewable sources, the amount of which varies depending on sunlight or wind conditions. You retain the freedom to choose your aggregator and to adjust your integration strategy during the contract period.
Structured / profiled PPA
You purchase a structured volume, known in advance, based on a defined profile (solar bell curve, monthly or annual baseload band). Mexens enters into a contract with its aggregator to supply you with the agreed profile. Maximum predictability, simplified integration.
Multi-technologies
Combine solar, wind and storage for a more consistent supply and better smoothing of output. Combining these technologies reduces the risk associated with output fluctuations and improves the coverage of your energy needs.

An integrated producer, your direct point of contact
Mexens, an independent multi-energy producer
Unlike an aggregator or an intermediary, Mexens is an independent renewable electricity producer (IPP). We develop, build, and operate our own solar plants, wind farms, and biogas units. This integrated positioning guarantees you:
- A single point of contact, from negotiation to asset operation
- Perfect knowledge of the production assets backing your contract
- The ability to offer multi-technology solutions (solar + wind + biogas + storage)
- Responsiveness and flexibility in contract structuring
How does it work?
The PPA programme with Mexens
End-to-end support
Our teams analyse your consumption profile, your CSR objectives and your budgetary constraints to determine the most suitable contractual structure.
We identify the generation asset(s) to be linked to your contract (solar, wind, biogas, hybrid), define the supply profile, and determine the duration and price.
Mexens manages the operation and maintenance of the generation asset for the entire duration of the contract. You will receive regular reports on the volumes generated and the guarantees of origin.

Your questions about the Corporate PPA
A Corporate PPA (Power Purchase Agreement) is a long-term electricity purchase contract concluded directly between a renewable energy producer and a corporate consumer. It allows the electricity price to be fixed, generally over 10 to 20 years, and is backed by an identified generation asset (solar farm, wind farm, biogas plant).
A physical PPA provides for the actual delivery of electricity through the grid, between the generation asset and your consumption site. A virtual PPA (VPPA) is a financial instrument structured as a “contract for difference”: it does not involve physical delivery, but rather a financial settlement based on the difference between the PPA price and the market price.
Corporate PPAs are primarily intended for companies whose annual electricity consumption exceeds around 10 GWh. However, multi-buyer models (aggregation of several consumers) make it possible to open access to PPAs for mid-sized organizations as well.
Additionality refers to a situation where the PPA contract directly enables the financing and construction of a new renewable generation asset (a “Greenfield” PPA). It is the most demanding CSR criterion, as it proves that your contract has generated additional renewable capacity on the grid.
Yes. The ARENH mechanism (Regulated Access to Historic Nuclear Electricity), which allowed suppliers to purchase nuclear electricity at a regulated price, ended in 2025. This change increases the relevance of PPAs as a long-term energy cost hedging tool.
