The 69 kV South Bangkok Substation Project constructed by POWERCHINA is expected to boost regional power supply capacity in Bangkok.

The 69 kV South Bangkok Substation Project in Thailand, constructed by POWERCHINA, was recently completed and handed over. It is set to provide vital energy support for Thailand's economic development.

The project is located within a power plant in southern Bangkok. The power transmitted covers downtown Bangkok and the key surrounding industrial area of Samut Prakan Province, making it a crucial hub for supporting the stable operation of the power grid in Thailand's core economic zone.

The new substation was constructed relying on the area of the existing power plant, representing a comprehensive upgrade and renovation of the old facility systems.

Upon operation, the project will alleviate the load pressure on Thailand's transmission system and boost regional power supply capacity, helping relevant areas strengthen energy security and improve energy utilization efficiency.

It will also hold great significance for the overall optimization of Thailand's power network. It will promote regional economic development, and provide a solid guarantee for the stable operation of the main grid and industrial development in the relevant areas.

The handover of the project demonstrates POWERCHINA's high-quality execution capabilities in the Thai market and the influence of the POWERCHINA brand in the local market.
