Calculation boundary (unless otherwise noted) : JERA in Japan, Hitachinaka Generation Co., Inc., and JERA Power TAKETOYO LLC, JERA Power Yokosuka LLC, JERA Power Anegasaki LLC
Calculated based on our own facilities as of the end of the fiscal year (March 31) of the year in which the data was collected. Overseas businesses are calculated based on facilities owned as of the end of the local fiscal year.
Including data from Green Power Ishikari LLC
Calculated from the percentage of time excluding planned internal and external outage time
Figures for JERA operations in Japan
Totaled on a wet coal basis (ar: as received)
Totaled on a dry basis (ad: air dried)
Calculated based on the Act on Promotion of Global Warming Countermeasures.
Calendar year totals
Calculated by using the adjusted emission factor for each electric utility published by Ministry of the Environment and Ministry of Economy, Trade and Industry.
From FY2021, part of purchased electricity is replaced by self-transmission, and the emissions associated with self-transmitted electricity are accounted for as Scope 1 emissions.
Calculated by the formula below in accordance with “Basic guidelines on accounting for greenhouse gas emissions throughout the
supply chain(ver.2.6)" on "Green Value Chain Platform (Ministry of the Environment website)"
Category 2： "Increase in book cost of property, plant and equipment (excluding land and construction in progress) and intangible assets (software, etc.)"×"Emission factor 1"
Category 3： "Electricity received from other companies"×"Emission factor 1"+"Fuel consumption"×"Emission factor 2"
"Emission factor 1" Cited from "Emission factor database for corporate GHG emissions accounting over the supply chain (Ver.3.4)" on "Green Value Chain Platform (Ministry of the Environment website)"
"Emission factor 2" IDEA Ver. 3.4 (2024/04/30), taken from IDEA Laboratory, Safety Science Research Division, The National Institute of Advanced Industrial Science and Technology.
Figures based on net power generation
Calculation boundary：The Calculation boundary of *1 plus joint venture figures.　Joint venture figures calculated based on JERA equity stake
Calculation boundary：The Calculation boundary of *11 plus totals for overseas businesses.　Totals for overseas businesses are generally aggregated based on local fiscal years and reporting standards, and calculated based on JERA equity stake
