Based on IEA data, transmission and distribution (T&D) losses in electricity networks in ASEAN vary from a low of 4.4% to a high of 15.6 % of final consumption. About a third of T&D losses take place in distribution transformers (DTs). About 80% (or more) of DTs are used by distribution utilities while demand from industry and buildings is growing.


- Reduce distribution losses by over 15,000 GWh per year, corresponding to 9 MtCO2 emission reduction

Strategic Approach:

- Harmonize standards to new IEC 60076-20

- Adopt regional and national policies to adopt MEPS and set timeline for progressive increase

- Build capacity of repair workshops to stop energy efficiency loss during repair (installed transformers)

- Create awareness among large industry and buildings by cooperating with utilities

Achievements to date:

- Scoping study completed: analysis of potential, analysis of barriers, policy recommendations. Download the report here.

Action Plan:

The Action Plan for the promotion of higher efficiency distribution transformers is presented below:

Standards: all ASEAN Member States adopt the new IEC 60076-20 standard

- Form Technical Working Group (TWG) composed of representatives from power utilities, standard making bodies, manufacturers, and ministry of energy: the TWG will lead the standards harmonization process under the technical guidance of an international expert

- TWG meetings

- In-country stakeholders’ consultations by international consultant

- TWG submits recommendations to the EE&C SSN for adoption by ASEAN MS

- Following endorsement by EE&C SSN, the decision to adopt the IEC standard will be adopted by SOME and AMEM as part of the regional policy roadmap

Regional Policy Roadmap

- Form the Policy Working Group (PWG), composed of representatives from ASEAN ministries of energy: the PWG will prepare the regional policy roadmap under the technical guidance of the ASEAN SHINE Technical Support Team (UN Environment, CLASP, ICA; external resources will be secured if required)

- PWG meetings

- Impact assessment study

- Following endorsement by EE&C SSN, the regional policy roadmap will be adopted by SOME and AMEM

National Policy Roadmaps

- Each ASEAN Member State will develop and adopt its national policy roadmap to achieve the long-term goals set out in the regional policy roadmap

- The national policy roadmaps will include a timeline for the progressive increase of MEPS

- For each country:

- Form National Steering Committee, chaired by the ministry of energy

- Form Country Chapter, assembling all relevant national stakeholders (manufacturers, industry associations, government, …)

- Develop national policy roadmap in consultation with Steering Committee, with technical assistance from the ASEAN SHINE Technical Support Team (UN Environment, CLASP, ICA, external consultants if required)

- Organize Country Chapter meetings for consultation

- Once approved by the National Steering Committee, the national policy roadmap will be endorsed by the ministry of energy

End-users awareness campaigns: (according to plans laid out in the national policy roadmaps)

- For distribution utilities: face-to-face meetings, technical seminars

- For industry and buildings:

- Work with distribution utilities to outreach to industry and buildings that request connection license

- Develop marketing strategy and plan

- Develop Total Ownership Cost (TOC) software

- Organize technical seminars for energy managers and purchasing officers

Capacity building for local manufacturers:

- Develop Eco-Design guidelines

- Organize technical training seminars

Capacity building for repair workshops:

- DTs undergo several repairs during their lifetime, and efficiency drops during repair due to poor repair practices

- ASEAN SHINE will embark in the training and certification program, in cooperation with the relevant government agencies (ministry of energy, ministry of industry, distribution utilities) and training institutions


Standards comparative analysis and preparation of policy recommendations, conducted by IIEC and funded by APEC:

- Regional stakeholders’ consultation workshop in Seoul on 28 March 2017

- Draft report in August 2017

- Second consultation workshop and international conference in December 2017
