Outline of GHG Mitigation Activity

This project is to conduct a rehabilitation for Karai 7 Hydro Power Project (2 x 3.54MW) located in the north Sumatra, Indonesia.

By introducing the latest turbine technology of Voith Hydro including High Velocity Oxygen Fuel (HVOF) coating to increase wear resistance and replacement of generator, the maximum output and annual power generation are expected to increased by 8.8% and 5.7% respectively.

Expected GHG Emission Reductions

1,133 tCO2-eq./year

= Reference CO2 emissions [tCO2/year]

     – Project CO2 emissions[tCO2/year]

= (Power generation after rehabilitation[MWh/year]

– Power generation before rehabilitation[MWh/year])

       × emission factor [tCO2/MWh]

Site of JCM Project

The Karai 7 power station is located in Simalungun province and is located approximately 100km south from Medan, Sumatra's main city
