Chiba Thermal Power Station. [ edit on Wikidata] Chiba Thermal Power Station, is an operational thermal power station located in Japan, run by JERA, with a maximum output of 4380 MW. Originally built in the late 1950s as a coal-burning plant, it was later converted to a plant burning liquefied natural gas in the year 2000.
Coal is predominantly used as fuel to generate electric power in coal-fired power plants. Where bituminous coal, subbituminous coal, or lignite is burned to generate elecricity. In coal-fired power plants the heat produced by the combustion of coal is used to convert water into high-pressure steam, which drive turbines that produces electricity.
