After the Fukushima nuclear power plant disaster caused by a tidal wave in March, 2011, Japan and several other countries questioned their nuclear commitment. Japan then took all of its nuclear power plants (NPP) offline; Germany soon followed suit. Other countries such as France and South Korea, while reviewing their NPPs, depending too heavily on them for total electrification of their countries (77 percent and 31 percent, respectively), could not.
The alternative to taking NPPs offline was to ramp up fossil fuel usage (coal, gas and diesel fuel) to make up for the electrical shortages. This was great for politics and immediate safety concerns, but horrible for the environment in the long term.
President Joko “Jokowi” Widodo has now sought an ambitious 35 gigawatt (GW) electric expansion, which includes electricity generation, transmission and distribution. A total of 25GW of this would be provided by independent power producers (IPP) and state electric company PLN would provide the other 10GW.
