Tackling contaminated transformer oil in Vietnam


Witteveen+Bos has been commissioned to identify all contaminated transformers and capacitors at Vietnam’s electricity stations as part of the Vietnamese government’s PCB Management Project. Management plans will subsequently be drawn up for locations where the oil-containing machines will be stored and processed. The oil of 50,000 installations is likely to be analysed. Employees of the electricity stations will be trained to perform sampling on their own. The analyses will be carried out in close cooperation with a local firm.

The Vietnamese authorities are cooperating with the World Bank on implementing the PCB Management Project. The project stems from arrangements agreed under the Stockholm Convention for tackling Persistent Organic Pollutants (POPs). PCBs are carcinogenic POPs that occur in transformer oil and elsewhere. Vietnam has announced that use of devices that contain PCBs must end by 2025 and that all devices contaminated with PCBs must have been dismantled in an environment-friendly way by 2028 at the latest.

Witteveen+Bos is responsible for overall management of the project and for a significant part of the consultancy. The project will run for approximately two years.

Two years ago Witteveen+Bos established a representative office in Vietnam. Through the project now acquired Witteveen+Bos expects to obtain an excellent position in the region for tackling environmental pollution.
