JERA retires four old LNG power plants as it builds three new units

Japan's biggest power generator JERA said on Tuesday it has retired four old liquefied natural gas (LNG)-fired power plants at its Anegasaki thermal power station in Chiba, near Tokyo, to make way for three new, less polluting units it is building. 

JERA, a thermal power and fuel JV between Tokyo Electric Power Company Holdings Inc and Chubu Electric Power Co Inc, said the plan was disclosed in 2016 that it would decommission the No.1 to No.4 units before the new units start operating in 2023, a company spokesperson said. 

The four 600 megawatts (MW) units that have been shut down were built between 1967 and 1972. 

The move reflects the utility's effort to cut CO₂ emissions by closing or reducing old and inefficient power generation units and building new facilities with higher efficiency. 

With the three new 650 MW units that are under construction, together with the remaining No.5 and No.6 units, Anegasaki station's annual CO₂ emissions are estimated at 9.2 MM tons when operated at 90% run rate, down about 30% from 13.5 MM tons emitted previously, the spokesperson said. 

Japan, the world's fifth-biggest carbon emitter, has pledged to cut GHG by 46% by 2030 on 2013 levels and it has raised targets for renewables in the nation's electricity mix while trimming targets for use of coal and LNG.
