Despite falling costs around the world for renewable technologies, solar and wind project costs remain elevated in Southeast Asia due to lack of deployment scale and underdevelopment of supply chains.
The results of this analysis show there is abundant potential for utility-scale, land-based wind and solar PV development in the ASEAN member states at a range of generation costs.
Significant declines in the mean LCOE for solar PV are seen in most countries. Brunei, Indonesia, and the Philippines see a 40% or greater drop in the mean LCOEs from the Base Scenario to the Low Installed Cost Scenario. For example, the mean LCOE in Indonesia falls from approximately $165 to $96 USD/MWh, respectively.
10 ACE (2019) estimated that LCOEs for solar PV generation ranged from $99 to $200 USD/MWh and that LCOEs for wind generation were approximately $150 USD/MWh in 2018 in the ASEAN member states. renewables can be developed often impact the feasible areas considered by developers and the resulting generation costs.
