| Abstract | The study presents an economic analysis of investment in cogeneration technology in
sugar industry under the time of day electricity buyback rate based on per unit
avoided cost of utility. Thai sugar industry is separated into 3 groups: small, medium
and large size depend on its milling capacity. Economic indicators were used in the
evaluation of the co generation project such as: the net present value, the internal rate
of return and payback period analyses in evaluating its economic feasibility
commonly used in the decision process for investments.
The study calculated the system avoided cost due to cogeneration plants based on
traditional resource planning and integrated resource planning and also considered the
effect of the system avoided cost with the level of co generation capacity.
The study has examined utility expansion planning, economics implications and
environmental implications of electricity generation system expansion on
cogeneration plants in Thai sugar industry based on traditional resource planning
(TRP) and integrated resource planning (IRP). The study shows that cogeneration is
selected as an additional plants in expansion schedules. C02 emission trading could
have the positive impacts on cogeneration plants because they would be selected
faster. In economic implication of cogeneration plant, the study has found that the
additional cogeneration plants could reduce the system total cost in both TRP and
IRP. The study also analyses that introduction of co generation plant could have
negative impacts on the generation system reliability. With introduction of
cogeneration plants, the amount of C02, S02 and NOx emission would be reduced. |
