Analysis of Renewable Energy Installationwith Modelling of Electricity Supply System in Japan
The Great East Japan Earthquake and tremendous tsunami caused the accident of the Fukushima Daiichi Nuclear Power Plant in 2011. In response to this accident, the Japanese government stopped almost all nuclear power plants and shifted to an electricity supply system with slight nuclear power genration and mainly with renewable energies. As the result, the ratio of the electricity generation of fossil fuel power increased larger than 25 % to compensate the nuclear power genration although Japan almost totally depends on imports for fossil fuels. Nevertheless, renewable energy technologies have been slowly installed. Those energy conditions have required to immediately create a well-planned electricity supply system to construct an energy-secure and sustainable society. Therefore, the energy best mix with renewable energy technologies must be built to solve the problems. The process to realize the best mix is urgently required to propose with concrete policies. Policies should effectively give the electricity market incentive of enhancing renewable energy technologies, because private companies manage the electricity supply in the free market in Japan. The current carbon tax policy rules that the tax revenue from carbon tax is spent in the energy-oriented CO2 emissions restraint measures. However, the effects of this for the sustainable society are unclear for civilians. Some subsidies are currently provided to the renewable energy installation by both the government and private funds. However, the current installation capacity of renewable energy technologies indicates that they are not enough. Therefore, effects of the circulation of carbon tax and the subsidy for renewable energy technologies (tax-subsidy circulation) are analysed with actual and simple assumptions in this study.The amount of the subsidy depends on the carbon tax rate in this assumption. Therefore, six scenarios are assumed depending on tax rates and provision of the subsidy. The subsidy is assumed to be spent in capital costs and operation and ...
