This public procurement is part of a comprehensive approach to energy transition and aims to design, implement, operate, and maintain (CREM) a set of innovative energy installations including:

• Photovoltaic plants installed on the roofs of three buildings and parking canopies, intended to produce local renewable electricity for self-consumption by each building;


• An electric storage system through stationary batteries for each building, allowing for optimization of self-consumption and self-production, managing production fluctuations, and ensuring better energy supply continuity;


• A hydrogen storage system (H₂), intended to produce and store hydrogen using the excess electricity generated by the photovoltaic installations, and also to produce electricity for the building's needs using stored hydrogen. The thermal energy generated by the hydrogen equipment must be valorized in the central building.

The services will be compensated by fixed prices.

Variants and potential additional services are planned:

• Mandatory Variant No. 1: Hydrogen Storage between 99kg and 1 ton


• Mandatory Variant No. 2: Wooden structure for canopies


• PSE No. 1: Stormwater management for canopies

The contract is a global performance contract awarded under Article L2171-3 of the Public Procurement Code with the objective that the contractor meets quantified performance targets. (see program)

The project will follow the following provisional schedule:

• Launch of the procedure with negotiation: February to May 2026


• Analysis of offers, selection of the contractor, and notification of the contract: June to September 2026


• Design phase: September 2026 to February 2027


• Submission of the APD: Mid-December 2026


• Implementation phase: May 2027 to June 2028


• Completion of work: October 2028

The chosen procedure is the one with negotiation, which is composed of two stages: the application and the offer (Article R2142-17 and following). At this stage, a candidacy is expected to meet the criteria set out in this notice and in the accompanying program, along with the DC1, DC2 forms, and tax and social certificates.

Additionally, the expected qualifications are as follows:

• QualiPV Élec: This qualification is aimed at electricians specializing in the commissioning of photovoltaic modules. It covers the electrical aspects of the installation, ensuring that everything is connected correctly and safely.


• QualiPV Bât: This qualification is aimed at construction professionals, such as roofers or waterproofers, who handle the integration of solar panels on existing structures. It guarantees that the modules are installed aesthetically and functionally, without compromising the integrity of the building.

The contracting authority limits the number of candidates allowed to submit bids to 4 (maximum). In accordance with the public procurement code, the number cannot be less than three unless the number of sufficient applications is less than 3.

The dates for the invitation to tender and the start of the execution of the contract are provisional.

The estimated value stated only includes studies and works.
