The core scope of work and statement of work summary for this tender primarily involves the development and operation of a power generation facility, likely solar, with a focus on self-consumption and potential resale of electricity.

The key deliverables and scope of work are categorized into investment (CAPEX) and operational (OPEX) aspects:

Investment (CAPEX) covers:

• Site preparation and monitoring.
• Supply and installation of panels and inverters.
• Supply and installation of primary and secondary structures.
• Foundations and general utilities (VRD).
• Electrical engineering and telecom connection.
• Monitoring, metering, and irradiance systems.
• Commissioning, testing, and documentation.
• Administrative fees, including those for Consuel and control offices.
• Miscellaneous items to be specified.

Operation (OPEX) includes:

• Annual exploitation and maintenance.
• Telecom and remote monitoring services.
• Insurance.
• Provisions for panel cleaning and inverter replacement over 25 years.
• Annual IFER tax and ACC fees (to be specified).
• Other operational costs to be specified.

The project also requires detailed central plant sizing and autoconsumption analysis, including specifying the power (kWc), surface area (m²), contractual reference output for year 1, annual sunshine hypothesis, contractual reference irradiation, annual production degradation coefficient, and projected annual production and performance ratios over 25 years. This includes monthly data on site consumption, central production, self-consumed energy, energy consumed by the collective self-consumption (ACC) loop, and energy resold to EDF OA.
