Japan: Installed Electricity Capacity, Generation and Consumption [free access]

June 8, 2018

Japan had an installed electricity generation capacity of 291,837 MW as of March 2016.  Of the total installed capacity, 65 per cent was based on thermal sources followed by hydro and nuclear sources, which accounted for a 17 per cent and 14 per cent share, respectively.  During 2016, the installed capacity decreased, mainly on account of the shutting down of nuclear capacity in line with the country’s plans to phase out nuclear power by 2040.

 

Also, over the next few years, electricity from coal-fired power plants is expected to remain the same, while electricity from liquefied natural gas (LNG)-fired power plants will decrease, thus leading to a decline in thermal capacity. The focus will shift to renewable energy resources, mainly solar.

 

Japan’s power sector is dominated by 10 electric power companies (EPCos), which operate as vertically integrated regional monopolies. Though independent generators have been allowed to operate since 1995, their participation has been low.
