|Study Partners||Hitachi Zosen Corporation, PT. PLN (Persero), and Mogok Image Construction|
|Location of Project/Activity||Myanmar (Mogok City) and Indonesia (Nias Island)|
|Category of Project/Activity||Renewable Energy and Energy Efficiency|
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/Activity||Hybrid 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.
|JCM Methodology||Eligibility Criteria||

|1-2Destination of the power supply|
|2 Technological criteria to maximize the potential of solar energy||2-1 Temperature coefficient of PV panel|
|2-2 Operation load of diesel engine|
|2-3 Usage of battery|
|3 Technological criteria to provide high-quality base load power||3-1 Functions of hybrid system controller|
|4 Maintenance criteria to secure the performance within the endurance period||4-1 Maintenance contract|
- 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 Emissions||CO2 emissions are calculated as a result of combustion of fossil fuels in power stations connected to the grid along with the reference scenario.|
|Monitoring Method||Quantity 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 Reductions||Calculation 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 Impacts||No environmental impacts. |
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%.
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 Technologies||Solar-Diesel Hybrid system is Japanese own technology that can stabilize solar power generation output.|
|Sustainable Development in Host Country||Installment 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.|
