UNEP Survey Report Power Quality for Indonesia, Thailand and Vietnam


Electric power quality (PQ) disturbances can have significant economic consequences for many different types of facilities. Although power quality is widely recognized as an important issue in Europe as well as in the USA, there is limited knowledge of PQ in Southeast Asia (SEA).

The PQ Loss Survey is a method to identify and benchmark the costs related to poor PQ in industry and services. The information obtained from this survey will help create awareness among policy makers and the private sector regarding the impact of power quality in terms of technical and economic losses.

This report presents the PQ Loss Survey in industry and service sectors in SEA. The survey was conducted over a 1-year period in Indonesia, Thailand and Vietnam. The survey results show that both industry and services sectors lose up to 1 billion USD annually as a direct result of their electrical power installation not being sufficiently reliable and resilient.
