Beyond tripling: Keeping ASEAN’s solar & wind momentum

ASEAN's solar and wind generation grew by 43% annually between 2015 and 2022, largely driven by Viet Nam's Feed-in Tariff policies. However, growth slowed in 2022, and the region currently utilizes less than 1% of its theoretical solar and wind potential. To meet the IEA's 2050 net zero scenario, ASEAN must reach a 23% share of solar and wind in total electricity generation by 2030, requiring the addition of 164 GW of solar and 65 GW of wind capacity. The report argues that achieving this requires removing regulatory barriers like local content requirements, investing in grid modernization and storage, and implementing attractive pricing mechanisms.

• To align with the IEA's 2050 Net Zero Emission (NZE) scenario, ASEAN must achieve a 23% share of solar and wind in total electricity generation by 2030, which necessitates adding 164 GW of solar and 65 GW of wind capacity.
• ASEAN has significantly underutilized its renewable energy potential; as of 2022, the installed capacity of 26.6 GW of solar and 6.8 GW of wind represents less than 1% of the theoretical potential of 30,523 GW for solar and 1,383 GW for wind.
• Viet Nam has been the primary driver of the region's clean energy growth, accounting for 69% of ASEAN's combined solar and wind generation in 2022, largely due to its 2017 Feed-in Tariff policy.
• Solar and wind generation growth in ASEAN slowed in 2022, increasing by 15% (+6.4 TWh) compared to a 67% (+18 TWh) increase in 2021, partly due to the phase-out of Viet Nam's Feed-in Tariff scheme.
• Local content requirements are identified as a barrier to competitiveness; for example, Indonesia's requirement for 60% domestic content for solar modules by 2025 may impede projects because domestic modules cost around 1 USD/MWh compared to 0.17 cents USD/MWh for Chinese imports.
• The report identifies critical infrastructure and policy needs to accelerate deployment, including grid extensions, modernization, energy storage facilities, and the implementation of auction mechanisms or green electricity tariffs.
