études pour projets photovoltaïques sur bâtiments

The contract timeline is as follows:

The framework agreement has an initial duration of 1 year, commencing on November 8, 2026, and concluding on November 7, 2027.

The agreement includes a tacit renewal option for two additional periods, with each renewal period lasting 1 year.

The total maximum duration of the contract, encompassing all periods, is 3 years, extending until November 7, 2029.

Key phases or milestones involve the execution or delivery of services, with deadlines specified for each purchase order as per the framework agreement. A prolongation of the execution period may be granted by the contracting authority under specific conditions.

The core scope of work for this tender involves performing studies for photovoltaic projects on buildings within the Department of Loire-Atlantique.

The statement of work summary outlines several missions with specific deliverables:

General Deliverables:

• All definitive documents must be submitted in dematerialized format (Word or equivalent, Excel or equivalent, and PDF).
• Deliverables must be sent by email to the contracting authority at least one week before being forwarded to the project owner.
• An example (fictitious or real) of a deliverable must be provided by the service provider for each mission as part of their offer.

Specific Missions and Deliverables:

• Lot 1 - Mission 1: PRE-DIAG
• A synthetic report (e.g., sheet, table, indicator) clearly showing the "photovoltaic compatibility index" of the project on a "risk scale" for the structure/roof, along with specified elements.
• Lot 1 - Mission 2: DIAG
• A diagnostic report (including visit report, results analysis, photos) presenting specified elements, which will be certifiable for the technical controller validating the installation, especially for Public Access Establishments (ERP).
• Lot 2 - Mission 1: Characterization of the Photovoltaic Installation
• A presentation support (PowerPoint or equivalent) for the final restitution meeting, which should be pedagogical and reusable by the project owner, detailing: site description, PV implantation (options, shading, power), PV field implementation (integration, reinforcements, costs), electrical implementation (inverter location, cable path), investment and operating costs, and the synoptic and principle of the PV installation.
• A final, synthetic report (Word or equivalent) incorporating all requested graphic and technical elements for the understanding of both TE44 and the final beneficiary.
• Lot 2 - Mission 2: Feasibility Study (VT or ACI)
• A presentation support (PowerPoint or equivalent) for the final restitution meeting, which should be pedagogical and reusable by the project owner, covering: optimal peak power determination, energy balance for self-consumption, economic results (flows, balances, sensitivity analysis), environmental balance, project planning, and a conclusion.
• A final, synthetic feasibility study report (Word or equivalent) integrating all requested graphic and technical elements for the understanding of both TE44 and the final beneficiary.
• Lot 2 - Mission 3: Study of a Collective Self-Consumption Project
• A presentation support (PowerPoint or equivalent) for the final restitution meeting, which should be pedagogical and reusable by the project owner, outlining: energy balance per consuming building, description of allocation keys, global and per-building economic results (indicators, business plan over 1 and 25 years), environmental balance, and a conclusion.
• A synthetic sheet (Word or equivalent) summarizing all requested elements, including graphic and technical details for the understanding of both the contracting authority and the final beneficiary.
