Study Report

Note: JCM proposed methodology, and calculation sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM.
Description of Project/ActivityIn this project, electricity supply from hybrid power system; solar power system, lithium Iron(III) phosphate-ion battery, and diesel generator, Sub-power will be installed to 50 mobile base station sites at the off-grid area. 50 sites location will be determined.
Power supply from solar system by capitalizing abundant sunshine, CO2 emission from fossil fuel will be reduced as a result of reduction of fuel for diesel generator.
JCM MethodologyEligibility Criteria
  1. Project site should be mobile base stations (MBS) in off-grid areas. (All MBS covered in this project are in off-grid area)
  2. Install a new solar power generation at a site where no renewable power generation was operated prior to the implementation of the project activity.( All MBS covered in this project are already existing ones)
  3. In case of existing MBS, prior to the project, diesel generator directly supplies electricity to the mobile base station.
  4. In case of new building MBS, diesel generator is installed as sub-power supply source.
  5. Hybrid system is the combination of the devices and technology: diesel generator, solar power, and storage battery, and operated without personal at the off-grid area
  6. Installed solar power generation system substitutes for a part of a power supply by diesel electric power generation.( In this project, 70% of electricity is supplied from solar power and 30% is supplied by diesel generator.)
  7. Adopt environmental safety storage, except a lead storage battery and a nickel cadmium storage battery in consideration of "the risk of environmental pollution" (In this project, lithium Iron(III) phosphate-ion battery, which is environment friendly and long life, is used.)
Default ValuesThe most fuel efficient diesel generator’s fuel consumption rate on the catalogue which is available in the market.
Calculation of Reference EmissionsTo calculate reference emissions amount by amount of diesel fuel consumption and diesel fuel origin CO2 amount when all needed electricity at MBS in an off-grid area is covered by diesel generator system only.
Monitoring MethodMonitoring parameters:
After completion of project (both new building and existing).Amount of electricity by solar system as main system
    • Amount of electricity by diesel system as Sub-power system.
    • Fuel consumption of diesel generator
    • Fuel amount consumed by diesel system
Monitoring Frequency:
(1)Project electricity output (power production) by solar power generation
    • Collecting electricity output data with validated/calibrate electricity monitoring devices (data logger) continuously
    • A Maintenance staff purchases stocked data from a data logger and input to a spreadsheet electrically in every 6 months.
    • Verified monitoring devices are installed and they are calibrated
(2)Project electricity output (power production) by diesel generation as sub-power supply
    • Collecting electricity output data with validated/calibrate electricity monitoring devices (data logger) continuously
    • A Maintenance staff purchase stocked data from a data logger and input to a spreadsheet electrically in every 6 months.
    • Verified monitoring devices are installed and they are calibrated
GHG Emission ReductionsCalculation of emissions reductions:
Emission Reduction amount, ER is calculated by the difference between Reference emissions and Emission amount from the project as below,
ER = RECO2 - PECO2
PECO2 of Renewable energy is 0, therefore, ER = RECO2
ER   Emission Reduction [tCO2e/y]
RECO2   Reference Emissions [tCO2e/y]
PECO2   Project Emissions [tCO2e/y]
Expected GHG Reductions: 2,905 (tCO2e/y)
Environmental ImpactsThere is no Legal requirement of environmental impact assessment for the proposed project.
Project PlanProject will be developed and planned by utilizing FY 2014 JCM Project Facility Subsidy Scheme.
Promotion of Japanese Technologies
  1. Japanese standalone technologies along with the system design technologies and knowhow that can combine such standalone technologies into a total system that will realize the optimal use of the individual technologies will be promoted.
  2. Lithium-ion batteries and nickel-hydrogen batteries that are more environment-friendly, long-life, space-saving and lightweight than lead storage batteries, will be promoted.
Sustainable Development in Host Country
  1. Development of skilled human resources and creation of new jobs in Indonesia
  2. Provision and expansion of distributed hybrid power generation systems in off-grid areas
  3. Contribution to energy security in Indonesia
