Smart Grid Interoperability Standards Adoption for Southeast Asia

Report: Smart Grid Interoperability Standards Adoption in Southeast Asia

An ITA-commissioned study by the Electric Power Research Institute (EPRI) assesses the landscape for clean energy standards adoption in Indonesia, Malaysia, Philippines, Thailand, and Vietnam.


In Southeast Asia, the market for smart grid technologies is rapidly growing. According to Fitch Solutions, the five Southeast Asian markets of Indonesia, Malaysia, the Philippines, Thailand, and Vietnam are expected to add over 50 gigawatts (GW) of generation capacity and spend upwards of $100 billion on grid upgrades and new power transmission and distribution networks by 2030. 
With the advent of new technologies like energy storage, electric vehicles, and automated demand-response, Southeast Asian markets will need to address the fundamental challenge of enabling power equipment and devices to communicate with one another to increase grid efficiency and reduce greenhouse gases. 

The importance of cross-border cooperation on standards will increase as Members of the Association of Southeast Asian Nations (ASEAN) work to create the “ASEAN Power Grid,” first envisioned by the bloc in 1999. In 2022, Singapore will begin renewable electricity imports from Malaysia and Laos, with the latter being the first 100 megawatts (MW) of electricity transmitted on the regional grid system developed under the Laos-Thailand-Malaysia-Singapore Power Integration Project. As regional partners look to further strengthen their energy security and expand the cross-border power trade, adopting common interoperability standards will be vital for vendors within or exporting to
 ASEAN’s single market.

Gap Analysis

This study analyzes the adoption of smart grid interoperability standards across the five largest U.S. electrical equipment export markets in ASEAN. Using the list of standards developed by the NIST Framework and Roadmap for Smart Grid Interoperability Standards 4.0 as a baseline, the study provides a comprehensive view of standards adoption within each country across multiple smart grid domains. 

The study found that IEC and ISO standards are well established in all five countries. Additional significant findings from the gap analysis include:

  • The national standards bodies in all five countries appear to only codify de jure standards produced by accredited international SDOs, and none from non-accredited industry consortia or alliances. 
  • Indonesia, Malaysia, and the Philippines showed evidence of accepting ISO and IEC standards but were not found to support relevant ANSI or IEEE standards families.
  • Thailand and Vietnam were found to accept a mixture of relevant ANSI, IEEE, ISO, and IEC smart grid interoperability standards.
  • Only Thailand was found to reference relevant ANSI and IEEE standards as mandatory standards.

The report draws insight from national grid codes, reports, articles, and equipment brochures to provide a detailed gap analysis of standards deployment in each country. It also includes a rich dataset of technical references for further study.

Case Studies

The analysis also provides use case studies on five emerging technology standards that have been successfully adopted in the United States. The study found that these emerging standards associated with the U.S. grid are either not accepted in the five ASEAN markets, or exist non-preferentially alongside other standards. 

The priority standards selected for case studies are: 

  • IEEE 1547-2018, Interconnection and Interoperability of DER with Associated Electric Power Systems Interfaces
  • IEEE 2030.5, Smart Energy Profile Application Protocol
  • OpenADR 2.0, Open Automated Demand Response
  • ANSI/CTA-2045, Modular communications interface for energy management
  • DLMS/COSEM (IEC 62056), Electricity metering data exchange

About Smart Grid Interoperability Standards

Smart grid interoperability standards are tools that enable technologies from different vendors across grid domains to interact. Standards may be mandatory and specified by the national grid code or national standards body, or they may be voluntarily adopted by private entities. In the fast-paced smart grid arena, traditional de jure standards developed and promulgated through accredited standards development organizations like the Institute for Electrical and Electronics Engineers (IEEE) or International Electrotechnical Commission (IEC) often run up against de facto standards promulgated by unaccredited industry consortia like the Wi-Sun or OpenADR Alliance. The U.S. government through the National Institute for Standards and Technology (NIST) has taken steps to build a solid framework and roadmap for deploying smart grid interoperability standards by working with stakeholders and partners from across industry, government, and academia. The NIST Framework and Roadmap for Smart Grid Interoperability Standards, 4.0 was published on February 18, 2021, and continues to be the guiding document for coordinating U.S. government work on grid interoperability.
