The Nakoso power station is a key infrastructure asset in Japan's power generation grid, located on the continent of Asia. Designated as a fossil fuel electricity generation station, the facility features an installed capacity of 1,700 MW. Its primary operation relies on harnessing coal energy resources to generate bulk electricity. Operational management and ownership of the facility are handled by the Joban Kyodo Power Co, which oversees daily maintenance and grid dispatch integration. The facility was officially connected to the commercial grid in 1986, since which it has maintained regular output, playing a structured role in domestic power supply security. In terms of domestic production capacity within Japan, Nakoso power station occupies the #13 position among all operational coal power plants. Its 1,700 MW capacity represents a 2.63% share of Japan's total installed coal generating capacity, which currently stands at 64,538 MW. The largest operational coal installation in Japan is the Hekinan Thermal Power Station with an output of 4,100 MW, making the Nakoso power station approximately 2.4 times smaller by comparison. Across all fuel types and electricity generation technologies country-wide, this facility accounts for 0.4739% of Japan's aggregate generation capacity of 358,713 MW. Based on historical capacity factors characteristic of coal power plants (modeled at 55% for analysis), the facility's expected annual electricity generation is calculated at approximately 8,190,600 MWh. Applying domestic consumption statistics where an average household in Japan consumes 3 MWh of electricity annually, this level of production is sufficient to meet the energy demands of roughly 2,730,200 homes. By utilizing traditional thermal power processes, the station delivers reliable dispatchable energy to the grid, supporting grid resilience during periods of low renewable resource availability and satisfying industrial base-load demands. The physical site of the station is located at geographic coordinates 36.9128° latitude and 140.8128° longitude. Analysis of local grid infrastructure shows a density of other assets within a 50-kilometer radius. These nearby facilities include Fukushima Daina (nuclear, 4,400 MW), Hirono Thermal Power Station (oil, 4,400 MW), Hirono Thermal Power Station (oil, 4,400 MW), representing a cluster of localized power assets. This geographic placement is vital for reinforcing regional distribution infrastructure and minimizing transmission line losses across this sector of Japan.
