Accelerating the global adoption of energy-efficient transformers - U4E policy guide series

This document provides an actionable guide for policymakers seeking to accelerate the global adoption of energy-efficient transformers. Drawing on the expertise of international organizations and practitioners, it outlines the urgent need to modernize transformer fleets to reduce technical losses in electricity distribution and address growing global energy demand. The document presents an Integrated Policy Approach, combining robust minimum energy performance standards, supportive policies such as labelling and institutional engagement, financial mechanisms to overcome upfront cost barriers, and strong systems for monitoring, verification, and enforcement. It also highlights the importance of environmental safeguards, including the safe handling and disposal of hazardous substances like PCBs found in older transformers.
