Installation photovoltaïque en autoconsommation zéro injection pour les besoins du Smdea (Ariège 09)

The contract timeline is as follows:

• Provisional Start Date: November 2, 2026.
• End Date: The works are expected to be received without reservations before the end of August 2027.
• Total Duration: Not explicitly stated as a single total duration, but the project is divided into phases.
• Key Milestones/Phases:
• Tranche Ferme (Firm Phase):
• Phase 1: Serres sur Arget / St Jean de Verges, with a maximum execution period of 10 months. The start date for this phase will be determined by a separate service order.
• Phase 2: Carbonne, with a maximum execution period of 10 months. This phase will start upon obtaining the modified building permit. The start date for this phase will also be determined by a separate service order.
• The preparation period for the site is included within each phase.
• Optional Tranches: There are two optional tranches whose deadlines are included within the duration of each firm phase. These correspond to an added value for installation on longrines if the micro-piled solution is not feasible.
• Document Submission: The contractor must submit all required documents at most 45 days before the start of the works. A Dossier des Ouvrages Exécutés (DOE) must be submitted at most 7 days before the reception of the works, and a Dossier d'Intervention Ultérieur sur Ouvrage (DIUO) at the reception of the works, if applicable.
• Warranty: The contract includes a perfect completion guarantee for a duration of 12 months.

The core scope of work for this tender involves the supply, installation, and commissioning of photovoltaic power generators. Key deliverables include the provision and installation of a data acquisition system compliant with CCTP for local or remote performance monitoring, including all necessary cabling. The scope also covers the interconnection of alternating current (AC) elements, which encompasses AC cabling between inverters and the site's General Low Voltage Panel (TGBT), trenching with conduits, installation of an IGBT PV, a main circuit breaker, and an emergency AC cut-off switch. Further, it includes the supply and installation of earthing and equipotential bonding for all metallic masses, cable marking, and a technical room. Depending on the project, the installation of an RFID electric vehicle charging station is also specified. Miscellaneous services are integral to the scope, such as material transport, site visits, safety provisions, testing, commissioning, and documentation. The tender also requires the obtainment of the CONSUEL certificate and attestation from the control office for commissioning, installation of a site signboard, and network detection. An optional, but mandatory, three-year preventive maintenance service, commencing from the work reception date, is also part of the scope. Specific photovoltaic equipment deliverables include junction boxes for PV module string coupling with protection devices, a synchronous inverter for public low voltage grid connection, a PV TGBT, electrical cabinets for the AC circuit with protection devices, a zero injection bridging system, and the connection of the solar plant to the injection point.
