A clustering of palm biomass power plant also needs close distance between POM and others. The distance is
not more than 20 km. In North Sumatera, there are around 70% of POM assessed have 10 to 20 km distance from
POM to others (Fig.3). A close distance from POM to grid line or to others POM shows that a clustering in
producing electricity from palm biomass is possible in North Sumatera.
