Specific fixed contract start or end dates are not provided. The total duration is not explicitly stated as a fixed period but is outlined through a series of milestones relative to "Zeitpunkt N".

Key milestones and phases include:

• Zeitpunkt N: Receipt and legal validity of official permits and placement of the individual order.
• N + Weeks:
• Delivery of documents relevant for building permits and client-side services (final version).
• Delivery of documents relevant for grid connection/grid feedback readiness (final version).
• Completion of client-side services at the work location and notification for inspection.
• Visual inspection of client-side services at the work location.
• Complete installation of the work.
• Readiness for grid feedback and notification.
• Visual inspection of grid feedback readiness.
• Declaration of readiness to conduct joint commissioning tests.
• Completion of commissioning of the entire work.
• Training of the client's employees.
• Delivery of complete work documentation.
• Final acceptance.

Additionally, there is a maintenance contract mentioned, with payments scheduled 96 months (8th year) and 108 months (9th year) after successful final acceptance, indicating a potential post-acceptance period of at least 10 years for the maintenance contract.

Contract start date, end date, and total duration as fixed calendar dates are not explicitly stated.

The core scope of work for this tender involves the delivery of a turnkey, complete, perfectly functioning, and commissioned Battery Energy Storage System (BESS). This includes the import and delivery of all individual components to the construction site, encompassing packaging, insurance, customs, and necessary permits. The contractor is responsible for confirming the completeness of the delivery in writing.

The Statement of Work (SOW) is detailed across several appendices and encompasses the following key deliverables and responsibilities:

• Installation Division of Responsibilities (Anhang C-1): Defining tasks for both the contractor and client until final acceptance.
• Services Division of Responsibilities (Anhang C-2): Outlining tasks for both parties after final acceptance.
• System Specifications (Anhang C-3): Providing essential specifications and key metrics of the BESS.
• Interface Specifications (Anhang C-4): Defining interfaces related to the client's scope of supply, such as the grid connection.
• Site Commissioning Testing (Anhang C-5): Describing the required commissioning tests.
• Remote Monitoring (Anhang C-6): Detailing the remote access concept for the system.
• Spares List (Anhang C-7): Listing necessary spare parts.
• Definitions for completion of client-side services, installation complete, readiness for grid feedback, and completion of commissioning (Anhang C-8 to C-11): These documents are to be developed after the award.
• Final Acceptance Metrics (Anhang C-12): Including availability criteria, such as available power >= 99% and an availability factor >= 96%, to be met without human intervention for three weeks prior to final acceptance.

The mandatory scope of the offer explicitly includes:

• Cabling between the battery-inverter/transformer and NS distribution.
• Transformers (battery transformers and auxiliary transformer with housing) designed to step up to 16kV/20kV and provide galvanic isolation.
• NIV registration and acceptance.

The contractor is also responsible for guaranteeing a usable energy capacity of at least 5.0 MWh for 10 years after final acceptance, with the possibility of replacing or adding battery modules to maintain this capacity. A usable active power of at least 1.3 MW is also required. Key components to be supplied include the complete battery system, complete inverters, and complete transformers. Performance guarantees also include a guaranteed State of Health (SOH), Round Trip Efficiency DC, and available energy DC, along with maintenance.
