| Abstract | Acid rain is an emerging issue in a number of Asia countries. The present study analyzes the
implications of demand-side technologies and sulfur tax as options for S02 mitigation from
the power sector.
The study examines utility planning and environmental implications of electricity generation
system expansion in Vietnam based on integrated resource planning (IRP) and compares the
same to those under traditional resource planning (TRP). A mixed integer programming based
IRP model has been used in this study to carry out generation expansion planning. The study
has found that from the long-term IRP perspective, total electricity generation, total generating
capacity addition, total expenditure and the environmental emissions would be reduced.
However, with IRP, the electricity price would be increased.
The utility planning and environmental implications are also analyzed for the introduction of
sulfur tax as a market option to mitigate acid rain causing emissions (ARCEs) in power sector
development. Four selected tax rates, i.e., US$500, 1000, 1500, 2000 per ton of sulfur (tS) are
considered. Capacity and generation mixes have shifted toward less sulfur intensive fuels and
technologies. Among introduced technology options of S02 abatement, only control
technology-FGD would be selected at tax rate ofUS$1000/tS and higher.
With the introduction of sulfur tax, an appreciable amount of S02 emission and other pollutant
emissions from power sector could be reduced. The reduction of S02 could reach to 50 % at
the tax rate of US$2000/tS. The reduction of S02 emission could take place through
technology substitution and demand-side effect, in which the dominant one is technology
substitution effect.
Through the use of integrated resource planning in power sector and RAINS-Asia model, this
study also analyzes the effect of IRP with and without sulfur tax on sulfur deposition in
several parts of Vietnam. Vietnam does not appear to suffer too much from acid rain problem
till 2020, except in two areas, the "potential hot spot area No. I" in the North and the "potential
hot spot area No.2" in the South. Both of these areas have the exceedance of sulfur deposition
density of higher than 1000mg/m
2
-year.
The present study also indicates that consideration of demand-side options through IRP and an
introduction of sulfur tax would reduce the acid rain problem significantly. The maximum
level of reduction of sulfur deposition could be made by tax is around 34% for the "potential
hot spot No.2" in 2020. It should be note that to solve the acid rain problem, sulfur tax should
be introduced for not only power sector but also all economic sectors. |
