The core scope of work and statement of work summary for this tender involves the design, supply, installation, commissioning, and operational delivery of solar panel installations and energy storage systems (battery packs) across five VRR locations, with a potential sixth location.

Key activities included in the scope are:

• All necessary engineering and work preparation.
• Implementation of safety measures.
• Coordination with the client (VRR) and other chain partners.
• Delivery of associated documentation, including drawings, measurement reports, and a handover file.

Following implementation, the contractor will be responsible for the management and maintenance of these installations for a minimum of four years. This maintenance includes monitoring and reporting annual yields, signaling, registering, and resolving malfunctions, and performing preventative maintenance (annual on-site inspection, checking proper functioning and safety of components like energy storage, panels, mounting system, cabling, and inverter, wind damage inspection, and maintenance according to manufacturer specifications). The contractor is also responsible for managing technical and functional changes, such as component replacement, firmware/software updates, and expansions within the agreed scope. Quarterly reports on performance, availability, faults, maintenance activities, deviations, and corrective measures are also required.

The project aims for approximately 210 kWp of solar panels and about 125 kW of battery capacity across these five buildings. The installations must be delivered fully operational within 9 months of contract award. The systems must be inspected by an independent SCOPE 12 inspector after installation, and the full electrical installation by an independent SCOPE 10 inspector. The contractor is responsible for resolving any deviations found during these inspections.

Items explicitly *outside* the scope of this tender include:

• Energy Management Software (EMS/EBS).
• Modifications to the existing distribution infrastructure (replacing, expanding, adapting, or modernizing the main distribution boards). The contractor will only work in collaboration with the VRR-appointed installation manager for connections.
• The costs for the one-time SCOPE 12 and SCOPE 10 initial inspections (EBI) are borne by the VRR and are outside the scope of this assignment.
• Costs (construction, general costs like permits) for external battery placement are outside the scope and need to be discussed during the project with VRR. Only the costs for the electrical part are within scope for external battery placement.The core scope of work for this tender involves the design, supply, installation, commissioning, and operational delivery of solar panel installations and energy storage systems (battery packs) on five VRR locations, with a potential sixth site also mentioned. This includes all necessary engineering, work preparation, safety measures, coordination with the client and chain partners, and the delivery of comprehensive documentation such as drawings, measurement reports, and a handover file.

After installation, the contractor is responsible for the management and maintenance of these systems for a minimum of four years. Key maintenance activities include:

• Monitoring and reporting on the guaranteed annual yield.
• Identifying, registering, and resolving malfunctions.
• Performing preventative maintenance, including annual on-site inspections, checking the proper functioning and safety of all components (energy storage, panels, mounting system, cabling, and inverters), inspecting for wind damage, and carrying out maintenance according to manufacturer specifications.
• Managing technical and functional changes to the installations, such as component replacement, firmware and software updates, and expansions within the agreed scope.
• Quarterly reporting on performance, availability, faults, maintenance activities, deviations, and corrective measures.

The project includes approximately 210 kWp of solar panels and about 125 kW of battery capacity across the buildings. All installations must be fully operational within 9 months of the contract award. The installed system must undergo an independent SCOPE 12 inspection, and the complete electrical installation must be inspected by an independent SCOPE 10 inspector, with the contractor responsible for resolving any identified deviations.

Items explicitly outside the scope of this tender are:

• Energy Management Software (EMS/EBS).
• Modifications to the existing distribution infrastructure, including replacement, expansion, adaptation, or modernization of existing distribution boards. The contractor will only collaborate with the VRR-appointed installation manager for connection work.
• The costs for the one-time initial SCOPE 12 and SCOPE 10 inspections (EBI) are covered by the VRR.
• Construction and general costs (e.g., permits) for external battery placement are outside the scope, and only the electrical portion for external placement is within scope.
