future investments in the power sector
It would require US$ 2,752 billion in investment for the Energy [R]evolution scenario to become reality (including investments for replacement after the economic lifetime of the plants) - approximately US$ 67.1 billion per year or US$ 1,470. billion more than in the Reference scenario (US$ 1,282 billion). Under the Reference version, the levels of investment in conventional power plants add up to almost 59% while approximately 41% would be invested in renewable energy until 2050.
Under the Energy [R]evolution scenario, however, the ASEAN region would shift almost 90% of the entire investment towards renewables. Until 2030, the fossil fuel share of power sector investment would be focused mainly on gas power plants.
Because renewable energy has no fuel costs, the fuel cost savings in the Energy [R]evolution scenario reach a total of US$ 2,698 billion up to 2050, or US$ 69.2 billion per year. The total fuel cost savings therefore would cover almost twice the total additional investments compared to the Reference scenario.These renewable energy sources would then go on to produce electricity without any further fuel costs beyond 2050, while the costs for coal and gas will continue to be a burden on national economies.
