Summary of FS ReportPDF (486KB)
Description of Project/ Activity<Installation of Storage Batteries>
Reducing fossil fuel use for power generation by installing storage batteries (including EV's batteries)

<Introduction of EV and Charging Facilities>
Reducing fossil fuel use for conventional vehicles by introducing EV and charging facilities
Reference Scenario and Project/ Activity Boundary<Installation of Storage Batteries>
    ・The case that conventional power is used without introduction of storage battery is set as "Reference Scenario".
    ・Boundary includes the supply of power charged and discharged from batteries.
<Introduction of EV and Charging Facilities>
    ・The use of fossil fuel-powered vehicle (not EV) is set as "Reference Scenario".
    ・Boundary includes emission from the usage of vehicle.
Monitoring Methods and Plan<Installation of Storage Batteries>
Need to monitor power charged to and discharged from batteries and emission factors of charged power and of replaced power by discharged.

<Introduction of EV and Charging Facilities>
Need to monitor power consumed, efficiencies of EV and reference vehicle and emission factors of fuel and power.
GHG Emissions and Reductions<Installation of Storage Batteries>
About 390,000tCO2/y (year 2022)

<Introduction of EV and Charging Facilities>
About 190,000tCO2/y (year 2026)
MRV System for GHG ReductionsMeasurement (M)
Monitor the targets above and measure the emission reduction. Flexible methodologies with a wide range of monitoring should be adopted, considering the future availability of simpler monitoring.

Reporting (R)
Report the result of monitoring annually.

Verification(V)
Verify the adequacy of monitoring
Analysis of Environmental, Socioeconomic and other Impacts (including Securement of Environmental Integrity)Developing pumping-up power plant is another way to make use of power surplus. Storage batteries should be adopted to avoid destruction of nature, which would be caused by development of pumping-up power plant.
    - When introducing battery or EV, it is also required to install battery recycling system.
Financial PlanningBoth introduction of batteries and charging stations are considered to be infrastructure building cost. Therefore it is not expected to bring high economic efficiency. However there is a good chance that acquiring credit would help the project implementation.
Introduction of Japanese TechnologySince Japanese technology in this field is highly developed the possibility of introduction is high. It is desirable for Japanese makers to receipt an order in full turnkey.
"Co-benefits"
(i.e. Improvement of Local Environmental Problems)
When transmission company adopts a long term fluctuation measure with NaS battery, annual emission reductions of SOx: 5,393kg, NOx: 10,785kg and Soot and dust: 539kg are expected.
Contribution to Sustainable Development in Host Country<Installation of Storage Batteries>
    ・Improvement of Energy Security
    ・Decline of Health hazard by cutting environmental pollutants
    ・Reduction of Risk of Economic and Social Loss from Blackout Risk Reduction
    ・Avoidance of New Development of Pumping-up Power Plant
    ・Accumulation of knowledge about grid stabilisation technology using batteries
<Introduction of EV and Charging Facilities>
    ・Improvement of Energy Security
    ・Decline of Health hazard by cutting environmental pollutants
    ・Preparing statistics and mileage standards of vehicle category
