Japanese energy giant Jera has moved ahead with its Chita LNG-fueled power plant rejuvenation plan with the filing of the environmental impact assessment scoping document to the authorities.
The construction involves decommissioning existing units one through five, retaining the sixth, and constructing two new 650-megawatt LNG power units, units seven and eight.
In order to reduce carbon dioxide emissions, the new units seven and eight are to adopt the combined cycle power generation system with a gross thermal efficiency of approximately 63 per cent.
Once the new constuction is finished, the environmental impact of smoke and warm wastewater is expected to be lower than for operations at the existing facility.
The submitted document describes items needed to conduct the environmental impact assessment including an overview of the project, a description of the area where the project will be carried out, and the assessment’s survey, forecast, and evaluation methods.
To remind, the five units set for decommissioning have a total installed capacity of 3,112 MW.
Units 1 through 4 are set to be decommissioned in FY 2021, according to the plan unveiled in October last year. Unit five is set for decommissioning in FY 2026.
The units 7 and are planned to start operation in August 2027 and December 2027, respectively.
With the 854 MW generated by unit 6, the Chiba thermal power plant will have a total generation capacity of 2,154 MW.
