High-Resolution Southeast Asia Wind Resource Data Set
With a 3-km spatial and 15-minute temporal resolution and a 15-year record, this first-of-its-kind public data set supports the informed deployment of wind energy across Southeast Asia.
For example, in Indonesia, coal- and gas-fired power plants currently provide around 80% of short-term flexibility with the remainder supplied by hydropower. These existing assets demonstrate that Southeast Asia already has a substantial foundation of flexible resources operating within current power systems.
Wind resources are more location-specific, with excellent offshore potential in the Philippines and Viet Nam and onshore wind potential in Cambodia, Myanmar, Thailand and Viet Nam close to urban centres. Southeast Asia's combined technical potential for utility-scale solar PV, onshore and offshore wind exceeds 20 terawatts.
While renewable technology costs in Southeast Asia remain higher than international benchmarks due to smaller markets and higher financing costs, solar and wind are becoming increasingly cost-competitive with new coal and gas across the region (particularly in the absence of fuel price subsidies).
Figure 8 A shows the distribution of solar, wind, and hydropower plants in Southeast Asia and their generating capacity. There are 246 solar power plants, 7 wind power plants, and 214 hydropower plants that were compared using the root mean square error (RMSE) and R 2.
