Flexible O&M Strategy in Semi-Flooded Terrain: PESE Optimizes Performance of a 110 MWp Solar Power Plant Cluster in Tay Ninh

Tay Ninh is currently recognized as one of Vietnam’s leading renewable energy hubs, thanks to its highly favorable climatic conditions. With average solar irradiance reaching 5.1 kWh/m²/day and approximately 2,400–2,700 sunshine hours annually**, the province offers optimal conditions for maximizing solar panel efficiency and ensuring high energy yield.

To date, Tay Ninh has attracted 11 large-scale solar power project with a total installed capacity of 1,188 MWp, playing a strategic role in Vietnam’s clean energy landscape while creating sustainable investment opportunities for project owners.

1. PESE Supporting a 110 MWp Solar Power Plant Cluster in Tay Ninh

As a professional Operations & Maintenance (O&M) service provider, is proud to be a trusted partner, directly managing the technical operations of a 110 MWp solar power cluster in Tay Ninh, including:

• Tan Chau 1 Solar Power Plant (50 MWp)
• Tri Viet 1 Solar Power Plant (30 MWp)
• Bach Khoa A Chau 1 Solar Power Plant (30 MWp)
• Tay Ninh 1 – 110kV Switching Station

Overcoming Challenges in Semi-Flooded Terrain

Unlike conventional ground-mounted solar projects, this solar cluster is located in a semi-flooded environment. This unique geographical condition creates major challenges in asset management, inspection, and maintenance, particularly in terms of site accessibility and operational safety.

For PESE’s engineers and technical specialists, however, challenging conditions are opportunities to demonstrate capability and resilience. Every on-site team member consistently upholds a strong sense of responsibility, strict discipline, and operational flexibility, ensuring readiness for even the harshest operating scenarios while safeguarding the investor’s assets.

2. Flexible O&M Solutions Tailored to Each Energy Project

To ensure investors can maximize asset value throughout the project lifecycle, PESE implements an integrated O&M strategy that combines:

• Plant Operation
• Corrective Maintenance
• Preventive Maintenance

This comprehensive approach is applied across the Tay Ninh solar plant cluster.

• Customized Maintenance Strategy for Every Plant
• Flexibility is at the core of PESE’s O&M philosophy. Depending on equipment characteristics, plant design configuration, and actual site conditions at each facility (Tan Chau, Tri Viet, or Bach Khoa A Chau), PESE carefully evaluates all technical factors to develop the most suitable maintenance methods and service intervals—rather than applying a one-size-fits-all approach.

In addition, strict daily inspection checklists enable PESE engineers to detect early signs of potential failures, allowing rapid isolation and immediate corrective action before risks escalate into major incidents.

3. Annual Preventive Maintenance: Professional, Efficient, and Safety-Driven

Preventive maintenance is a core operational activity designed to prevent critical failures before they occur while maintaining high plant availability and long-term performance stability.

PESE plans and executes preventive maintenance campaigns once per year, or according to schedules agreed upon with project owners.

Maximizing Energy Yield Through Night-Time Execution

To completely avoid generation loss and preserve daytime revenue for investors, PESE strategically performs all major shutdown, testing, and complex maintenance activities during evening and nighttime hours.

• Working without natural daylight requires meticulous preparation and flawless execution.
• Safety Comes First: All safety procedures, personal protective equipment (PPE), workwear, and professional lighting systems are prepared with the highest level of rigor to ensure safe operation.
• Intensive Technical Training: All personnel involved undergo strict safety training and possess deep understanding of system architecture, switching procedures, and equipment isolation protocols.

Key Technical Maintenance Scope

• The preventive maintenance campaign focuses comprehensively on: Primary equipment systems
• Secondary equipment systems, Control and protection systems associated with the integrated substation
• Servicing power transformer, RMU medium-voltage switchgear and inverter systems
• Measurement and testing of AC and DC cable systems
• Inspection and grounding resistance measurement of the earthing system

Delivering Professional O&M Excellence

The annual preventive maintenance campaign for the 110 MWp Tay Ninh solar power cluster was successfully completed with zero safety incidents, full compliance with schedule, and high technical accuracy.

All systems were re-energized and returned to operation in optimal technical condition, fully prepared to achieve new production milestones.

A truly professional O&M system does not wait for failures to occur before taking action. Instead, it proactively analyzes risks, adapts flexibly to operating conditions, and prevents failures before they have a chance to happen.

That is PESE’s commitment to protecting and maximizing the value of every client’s investment.
