Thailand Electricity Security Assessment 2016 Summary

Core Content

This document is the Thailand Electricity Security Assessment 2016, part of the IEA Partner Country Series. It is a peer review assessment of Thailand's electricity sector, aimed at supporting the country's efforts to achieve a secure, affordable, and environmentally sustainable transformation of its power system.

Thailand, as the second-largest economy in Southeast Asia, is undergoing significant structural changes in its electricity demand due to its rapidly growing middle class and industrial base. The report emphasizes the importance of electricity security and how it is a critical concern for the country's economic development and investment climate.

The International Energy Agency (IEA) has a dual mandate: promoting energy security and providing research and analysis on energy systems. Thailand became an Association country of the IEA in 2015, marking a milestone in its collaboration with the IEA on energy security and sustainable development.

Main Objectives

The primary aim of the report is to:

• Support Thailand in achieving a secure and sustainable electricity sector.
• Provide policy recommendations for improving market design and regulatory frameworks.
• Enhance the integration of renewable energy and improve grid flexibility.
• Ensure alignment with climate change commitments, such as the Paris Agreement and INDC (Intended Nationally Determined Contribution).

Key Information

Electricity Sector Overview

• Electricity demand is growing rapidly, with peak load increasing by nearly 50% over the past decade and average annual consumption growth at 5%.
• Peak demand is expected to double by 2036.
• Natural gas is the primary fuel for electricity generation (currently ~65% of the generation mix), but it is becoming increasingly constrained due to resource depletion and reliance on imports from Myanmar.
• Coal is also a significant source, expected to increase from ~20% to ~23% of the generation mix by 2036.
• Renewables are a growing component, with domestic renewables expected to double from 10% to 20% and imported hydropower increasing from 8% to 15%.

Power Sector Governance

• The Ministry of Energy (MoEN) sets policy goals.
• The Energy Regulatory Commission (ERC) implements and enforces these policies.
• The Electricity Generating Authority of Thailand (EGAT) is responsible for generation and transmission planning.
• The Metropolitan Electricity Authority (MEA) and Provincial Electricity Authority (PEA) manage distribution and retail markets.

Regulatory and Policy Framework

• Thailand has implemented the Power Development Plan (PDP2015), which outlines a 21-year investment schedule.
• The Alternative Energy Development Plan (AEDP2015) and Energy Efficiency Plan (EEP) are key components of the broader Energy Master Plan.
• The Fuel Adjustment Mechanism (FAM) and Power Development Fund (PDF) are central to financing and managing the power sector.

Renewable Energy and Support Mechanisms

• Solar PV is the largest component of planned renewable generation (6,000 MW), followed by biomass (5,570 MW) and onshore wind (3,000 MW).
• Feed-in-tariff (FIT) schemes are used to support renewables, but they have been implemented inconsistently.
• Permitting processes for renewables are complex and could be streamlined to support growth.
• Net metering and fixed FITs are mechanisms used to incentivize renewable adoption.

Energy Efficiency Measures

• The Energy Efficiency Plan (EEP) targets to save nearly 90 TWh of electricity by 2036.
• Key measures include improving MEPS (Minimum Energy Performance Standards) and HEPS (High Energy Performance Standards), enhancing building codes, and promoting LED usage.
• Over 75% of energy savings are expected from the commercial and industrial sectors.
• The EEP is ambitious, but implementation has faced challenges due to lack of coordination and slow development of MRV systems.

Grid Development and Transmission

• The Thai electricity grid is mainly located in the central and northern regions.
• High-voltage lines (500 kV) currently cover 13% of the grid and are planned to expand to the entire country by 2019.
• The grid must be upgraded to support the integration of variable renewable energy (VRE) and grid-connected solar PV.
• Network constraints, especially in the eastern part of the country, have limited renewable deployment.
• The transmission development plan is currently treated as a static input, rather than being co-optimized with generation planning.

Environmental and Climate Considerations

• Thailand's INDC targets a 20–25% reduction in power-related CO₂ emissions by 2030 compared to business-as-usual.
• The Paris Agreement requires increasingly stringent climate commitments, which will influence future Power Development Plans (PDPs).
• There is a need to re-evaluate coal generation levels to meet these future targets.

Recommendations

• Clarify roles and responsibilities among government agencies, especially strengthening the MoEN and ERC.
• Enhance the regulator's independence and expertise to ensure a proper balance between security, economic, and environmental goals.
• Increase the ambition of renewable targets, particularly for solar PV, and improve financing schemes.
• Expand MEPS and HEPS to more products and make more measures mandatory.
• Conduct transparent cost-benefit analyses for grid development in renewable-rich areas.
• Ensure power sector development plans align with future climate and environmental commitments.

Conclusion

The report highlights the importance of diversifying the power mix, improving grid infrastructure, and enhancing regulatory frameworks to support Thailand's transition to a cleaner, more sustainable energy system. It also underscores the need for greater coordination, policy consistency, and transparency in the development and implementation of energy policies. The IEA and Thailand are encouraged to continue their collaborative efforts to address shared energy challenges and contribute to a global sustainable energy transition.
