Reports of MOEJ/GEC JCM Feasibility Study: FY2013

Title of Study JCM Feasibility Study
Solar-Diesel hybrid system to stabilize solar power generation
FYFY 2013
Main Implementing EntityMizuho Bank, Ltd.
Study PartnersHitachi Zosen Corporation, PT. PLN (Persero), and Mogok Image Construction
Location of Project/ActivityMyanmar (Mogok City) and Indonesia (Nias Island)
Category of Project/ActivityRenewable Energy and Energy Efficiency
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/ActivityHybrid power generation systems, combined solar and diesel power generation facilities are introduced to connect the micro-grids at the rural area in Myanmar, and/or the isolated island grid in Indonesia, to supply electricity to these grids.
For Indonesia, the hybrid system is planned to be 1MW solar and 1.5MW diesel, and for Myanmar, 2MW solar and 4.5MW diesel (1.5MW x 3). The hybrid power generation system can stabilise and optimise the power generation by total system control.

Default Values
  • CO2 emissions factor of electricity in year y [tCO2/MWh]
  • Net Calorific Value of the diesel oil used for diesel engine [GJ/t]
  • Emission Factor of the diesel oil used for diesel engine [tCO2/GJ]
  • Net Calorific Value of fossil fuel i [GJ/mass or volume unit]
  • Emission Factors of the fossil fuels used for power stations connected grid in year y [tCO2/GJ]
Calculation of Reference EmissionsCO2 emissions are calculated as a result of combustion of fossil fuels in power stations connected to the grid along with the reference scenario.
Monitoring MethodQuantity of electricity generation fed to the grid by the project (MWh/y) : monthly
Quantity of diesel fuel consumption by the project: monthly (t/y) : monthly
GHG Emission ReductionsCalculation of reference emission: by measuring of combustion of fossil fuels in power stations connected to the grid along with the reference scenario (multiplied by the emission factor (default value or national grid).
Calculation of project emission: by measuring of combustion of diesel oil in the diesel engine that is a component of the hybrid system and total generation of electricity by the component of the hybrid system.
Estimated emission reductions:
[Indonesia] 2,112 tCO2/y
[Myanmar] 3,502 tCO2/y
Environmental ImpactsNo environmental impacts.
Project Plan[Indonesia]
In the proposed project, we plan to install a “PV/Diesel Engine Hybrid System” that has capacity of 1 MW (PV) and 1.5 MW (Diesel Engine). It will replace an island-grid-connected power in the Nias Island, which will be generated by diesel engines. Initial cost is planned to be invested by PLN in 50% and Japanese grant 50%.
[Myanmar]
In the proposed project, we plan to install a “PV/Diesel Engine Hybrid System” that has capacity of 2 MW (PV) and 4.5 MW (1.5 x 3 Diesel Engines). It will replace a micro-grid-connected power of the Mogok City, which will be generated by diesel engines, additionally. Initial cost is planned to be invested by MIC in 25%, SSG/PWH in 25% and Japanese grant 50%.
Promotion of Japanese TechnologiesSolar-Diesel Hybrid system is Japanese own technology that can stabilize solar power generation output.
Sustainable Development in Host CountryInstallment of this hybrid system can cause the reduction of fuel consumption by solar electricity generation and improvement of new diesel engine’s fuel efficiency, this could contribute for the sustainable development in the host countries.
