The Fukushima nuclear accident in 2011 had an extensiveimpact on the national electricity plans. Thispaper outlines alternative electricity scenarios thatmeet the goals of nuclear phase-out and greenhousegas (GHG) emission reduction. This paper also analyzesthe results of each scenario in respect to theelectricity mix, GHG emissions, costs and employmenteffects. The Long-range Energy AlternativesPlanning system (LEAP) model was used to simulatethe annual electricity demand and supply systemfrom 2011 to 2030. The reference year was 2009. Scenarios are reference (where existing plans arecontinued), A1, A2, B1, B2, and C2 (where the levelsof demand management and nuclear phase-out aredifferent). The share of renewable energy in the electricitymix in 2030 for each scenario will be increasedfrom about 1% in 2009 to 8% in the reference scenarioand from 11% to 31% in five alternative scenarios. Total cumulative cost increases up to 14%more than the reference scenario by replacing nuclearpower plants with renewable energy in alternativescenarios could be affordable. Deploying enoughrenewable energy to meet such targets requires aroadmap for electricity price realization, expansionof research, development and deployment for renewableenergy technologies, establishment of an organizationdedicated to renewable energy, and ambitioustargets for renewable energy.
