I. Introduction

In a market where businesses increasingly prioritize operational efficiency and system durability, the demand for reliable after-sales services has become more essential than ever. Beyond delivering high-quality products, we provide a comprehensive support solution that integrates warranty services and maintenance services to enhance client benefits and ensure long-term system stability.

Through a full life-cycle support framework, businesses can confidently rely on:

• Stable operational performance maintained over many years

• Reduced risk of unexpected failures

• Optimized operating and maintenance costs

• Extended system uptime and equipment lifespan

Real operational data—such as annual revenue forecasts, energy output performance, and storage efficiency degradation—offers clear proof of the optimum client advantage gained through our long-term cooperation model.

II. Long-term Cooperation

Based on a 15-year operation period, we provide realistic simulation data that allows clients to clearly understand the long-term value they will receive.

1. Forecasted Annual Revenue

With an operation frequency of 2 cycles per day, the system is projected to generate:

18,787,410 million VND in total revenue over 15 years

With a 15% revenue-sharing model returning 2,818,112 million VND to the client

Thanks to consistent performance and sustained output capacity over the operational lifecycle, the system demonstrates its ability to deliver significant long-term revenue. The revenue-sharing structure reflects transparency and mutual benefit—reinforcing the value of a long-term client partnership.

2. Energy Output Over Time

The chart illustrates a gradual decline in energy output over time, while still maintaining high efficiency.

• Year 1: 567.6 MWh
• Year 5: 485.6 MWh
• Year 10: 419.2 MWh
• Year 15: 347.1 MWh

Although the decline follows the natural characteristics of battery degradation, the system continues to operate reliably and meets the energy storage and discharge needs of the business. With proper technology and preventive maintenance, the output remains within an acceptable range, ensuring long-term value extraction.

3. Storage Efficiency Degradation

The system experiences a degradation rate from 96% to 61% over 15 years—an expected and stable index for industrial energy storage equipment. This performance decline follows natural battery aging, yet with robust engineering configurations and scheduled maintenance, overall efficiency remains sufficient to meet real-world operational requirements.

This stability contributes directly to predictable revenue and dependable performance throughout the project lifespan.
