Renovating the electrical system involves upgrading and repairing to enhance quality, ensure safety, and meet the increasing demand for electricity.
Overview of Electrical System Renovation
The renovation of electrical systems aims to enhance quality and reliability, ensuring a stable and safe power supply. The renovation scope may include upgrading or replacing power lines, substations, electrical equipment, and other systems. This is a crucial process for energy stability and cost optimization.
Renovating electrical systems plays a vital role in grid upgrades and ensuring a safe, stable power supply. This process is not only about repairs and upgrades but also adaptation to renewable energy sources and changes in electricity consumption demand.
Significance and Objectives of Electrical System Renovation
- Ensure Safety and Stable Power Supply: Renovating electrical systems helps resolve issues, reduce outages by upgrading substations and power lines.
- Supports Economic and Social Development: Upgrades better meet increasing electricity demands as the economy and population grow.
- Enhance Operational Flexibility: Renovation supports energy systems adapting to renewable energy source fluctuations, enhancing management and operation capabilities.
- Adapt to Future Development Trends: The power grid needs upgrading to be compatible with new energy source structures by 2050.
Key Activities in Electrical System Renovation
- Establish and Expand Power Grid: Building thousands of meters of new power lines and substations to increase electricity supply capacity.
- Renovate, Repair Major and Regularly: Replace outdated or overloaded equipment to maintain stable operation.
- Monitor and Flexibly Operate the Power Grid: Enhance inspection to prevent failures, applying appropriate operational solutions according to reality.
- Apply New Technology: Integrate energy storage systems to stabilize operations before renewable energy supply changes.
Challenges and Solutions in Electrical System Renovation
- Forecast Renewable Energy Sources: Accurately predicting power capacity from wind and solar sources is crucial for renovation optimization.
- Increase Capacity and Expand Scale: Renovating the power grid ensures effective transmission as power source capacity significantly increases.
- Ensure Safety and Reliability: Renovation plans should prioritize high-risk areas to limit failure impacts on economic and social activities.
The electrical system is not only the energy supply lifeline but also a lever for economic growth. Renovating electrical systems helps maintain a stable, quality supply, strongly supporting industrial development and daily life.

Electrical System Upgrade Process
The process of upgrading electrical systems includes stages: inspection and evaluation to identify parts for upgrading, system redesign to ensure efficiency and safety, repair construction, and finally, re-inspection of the entire system to ensure stable and efficient operation. Each stage requires precision and expertise to achieve the highest effectiveness.
In the electrical system upgrade process, surveying and planning is the important first step. This process requires meticulous evaluation of the current condition of the electrical system to accurately determine parts needing upgrading or repair. Specific goals such as project budget and timeline also need to be clearly defined to ensure progress and quality.
Designing a new electrical system is also an indispensable step to ensure modernizing requirements and performance optimization. This design must be approved by authorities before implementation to comply with all safety regulations and standards.
During preparation, procuring new electrical equipment is a crucial factor. Equipment from brands like Schneider, ABB, and Mitsubishi should be chosen to meet quality and high-performance standards. All equipment, before installation, must be thoroughly checked to meet safety and quality standards.
Safe electrical construction is the next important factor. Installation must be performed according to approved drawings and requires strict supervision to ensure compliance with all safety and quality regulations. Checking the electrical system upon completion is necessary to ensure no errors and the system operates stably and safely.
Especially in older facilities like apartments, electrical system upgrades often include renovating concealed and exposed wiring. This enhances safety and energy-saving capabilities. Electrical safety standards like TCVN 7447-5-51:2010 need to be strictly followed throughout the upgrade process to ensure the system operates safely and optimally.

Current Electrical System Renovation Projects
Currently, the Ho Chi Minh City Power Corporation is promoting the completion of grid upgrade projects, while Như Thanh – Như Xuân Electricity has completed many new medium-voltage power lines and substations. These projects not only improve voltage quality but also contribute to the stability of the national power system.
Currently, Vietnam is synchronously implementing many electrical system renovation projects to meet the increasing demand for electricity usage.
- Adjustment of Power Planning VIII: This planning is adjusted to ensure sufficient electricity supply for economic development. Adjustments include significantly renovating and constructing new substations and power lines. Specifically, plans include constructing 73,800 MVA and renovating 36,600 MVA of 500 kV substations, along with constructing and renovating thousands of km of 500 kV power lines.
- Development of Solar and Wind Power Sources: To enhance the exploitation of renewable energy sources, solar and wind power projects are being strongly invested in. The goal is to improve storage capacity and provide stable electricity supply during peak periods.
- Development of Pumped Storage Hydropower Plants: The trend of developing pumped storage hydropower plants is positioned with capacities ranging from 2,400 MW to 6,000 MW by 2030. This type helps balance the power grid, mitigating shortages during peak hours.
- LNG Projects: LNG power projects like Nhơn Trạch 3 and 4 are being implemented, supplementing power supply, diversifying energy sources, and reducing dependency on fossil fuels.
- Enhancing Management and Check: The government promotes enhancing management and check to ensure sufficient electricity supply throughout 2025, with close participation from ministries and power corporations.
These projects not only diversify energy supply sources but also ensure stability and sustainability for the future national power system.

Renovating the electrical system provides many benefits such as increased operational efficiency, system safety assurance, expanded integration capability of renewable energy sources, while also supporting economic and social development.
