events on the desirable pathway of power generation mix. As a future challenge to
be considered, the author attempts to conduct the evaluation of the optimal installed
capacity of fuel stockpiles and individual power generator in a long-term
perspective.
4 Conclusions
The Fukushima nuclear accident has necessitated the fundamental review of Japan’s
energy supply portfolio and is a turning point for the country to rethink energy,
environmental and nuclear policy acclimating to the socio-economic situation after
Fukushima. For developing effective long-term energy policy, it is important to
have a firm vision optimizing the country’s energy mix, considering contingency
risk such as nuclear severe accident which has actually and dramatically changed
the country’s energy balances. This chapter reviews the transition of energy balance
in Japan after Fukushima and discusses the potential energy modeling approach to
consider nuclear accident by applying stochastic dynamic programming.
To revise appropriately the long-term energy policy, various uncertainties need
to be considered, and the discussion over long-term energy planning should be
closely rooted in consistent and quantitative analysis based on certain mathematical
tool. In this context, the simulation tool such as stochastic dynamic programming is
expected to provide insight for developing effective energy policies. Actually,
however, constructing the optimal energy portfolio is not merely a discussion about
identifying the optimal combination of energy source. For the adequate formulation
of energy policy against various risks, comprehensive argument should be conducted in various viewpoints such as sustainable economic growth, energy resource
diplomacy and national technical competitiveness.
