Thailand Model: Base Case

Base Case assumptions:

  • Hydro Import:
  • Hydro Import:

– 4000 ktoe (Assumption: 21 GW of hydropower electricity is available as electricity import in the base case by 2050) y p y )

  • Nuclear will be introduced by 2020:

– 2500 ktoe (4000 MW)

  • Nuclear power generation will be available to the

maximum of

– 20,000 ktoe by 2050

  • Biodiesel (B10) will be available up to

40 000 kt b b 2050 – 40,000 ktoe by by 2050

  • Gasohol (E10) will be available up to

20 000 ktoe by 2050 – 20,000 ktoe by 2050.

Concluding Remarks

T hi t t f 15% d ti i CO

  • To achieve a target of 15% reduction in CO2

emission,

CCS d bi d l t h l i th – CCS and combined cycle technology in the power sector would play a major role. – Renewable energy would not be contributing Renewable energy would not be contributing significantly in CO2 reduction in the power sector. – In transport sector, bio-diesel, gasohol and hybrid vehicles would have significant role in emission reduction. The results would be affected if modal shift to – The results would be affected if modal shift to railways and other mass transport systems are considered.
