O&M – The Decisive Factor Behind the True Value of a Power Plant

A power plant may take several years to build, but its profitability is proven over decades of operation.

After construction is completed and Commercial Operation Date (COD) is achieved, the most critical phase begins: Operation and Maintenance (O&M). This stage determines the plant’s performance, asset lifespan, and long-term financial returns.

Whether it is solar, wind, thermal, or hydropower, every technical system experiences wear and degradation over time. Without a structured O&M strategy, power plants face declining output, increasing repair costs, and operational disruption risks.

What is Operation & Maintenance and Why is It Essential?

O&M encompasses all operational activities, including:

• System operation and control
• 24/7 technical monitoring
• Production data analysis
• Preventive and corrective maintenance
• Safety control and regulatory compliance

The design lifespan of power plants ranges from 25–30 years (renewables and thermal power) to 50–100 years (hydropower). However, actual lifespan depends heavily on the quality of operation and maintenance services.

Investing in professional O&M services helps:

• Maintain stable performance
• Reduce unplanned downtime
• Optimize life-cycle costs
• Manage long-term cash flow

With rapidly growing electricity demand in Vietnam and Southeast Asia, O&M is no longer merely a technical expense — it is a strategic business component.

Self-Operation or Outsourced Power Plant Operation?

Many investors choose to operate plants internally, expecting better control and cost savings. However, in practice, this model often faces significant challenges:

• High technical staffing costs
• Limited expertise in complex troubleshooting
• Requires a systematic/structured system setup and significant investment resources.
• Requires a solid understanding of dispatching procedures, power systems, and relevant legal/regulatory frameworks
• Insufficient monitoring and data analytics technology
• Difficulty optimizing long-term performance

By contrast, outsourcing O&M services provides:

• Experienced engineering teams
• Digital monitoring systems with real-time analytics
• Leverages modern facilities and equipment that are regularly upgraded
• Structured operation and maintenance programs
• Reduced technical and regulatory risks

For many projects, especially during the early years of operation, outsourced O&M is the optimal solution to ensure stability and operational safety.

The Major Mistake: Choosing Low-Cost O&M Providers

One common risk is selecting the lowest-cost O&M provider to reduce initial expenses.

However, in the energy sector, a “low-cost” mindset can lead to:

• Increased plant downtime
• Declining electricity output
• Severe equipment damage
• Regulatory non-compliance and penalties
• Loss of credibility with partners and authorities

Initial savings are often insignificant compared to long-term losses. O&M is the phase where asset value must beprotected

Core Value of Professional O&M Services

• Continuous and Stable Operation: 24/7 monitoring, real-time data analysis, and early-warning systems minimize operational risks.
• Optimized Power Generation Performance: Operational parameter adjustments and preventive maintenance ensure maximum output throughout the project lifecycle.
• Regulatory Compliance and Safety Assurance: Full compliance with technical, environmental, and occupational safety standards in Vietnam and internationally.
• Extended Asset Lifespan: Proper maintenance enables plants to fully realize their design life and reduces premature equipment replacement.
