| Abstract | The installed capacity in North Sulawesi is diesel (68 MW) and hydro (51 MW). The current annual electricity demand is 636 GWh. Due to difficulties in obtaining secure and reliable supply electricity in this island community, alternative options are needed. This study aims to assess (i) the technical potential of renewable energy resources to supply electricity (ii) lighting demand side management (DSM) application to reduce electricity demand and (iii) C02 emission mitigation by the use of renewable energy resources and lighting DSM implementation in North Sulawesi province, Indonesia. The potential of solar, wind, biomass, micro hydro and geothermal has been assessed based on available data. For solar energy resource, the monthly average daily global and daily diffuse radiation, the monthly average hourly global and diffuse radiation, monthly average sunshine duration have been calculated and tabulated. A yearly average daily radiation of 20.5 MJ/m2 and about 5.8 hours sunshine duration are available. These results have been compared with data from nearby locations. A study correlating the sunshine duration and monthly average global radiation has been done. For biomass resource, the recoverable energy potential from selected crop residue (paddy, maize and coconut), forest residue (logging and sawn wood) and animal waste has been estimated. It is estimated that about 3070 TJ/year is available from these biomass residues. The study indicates that the wind energy potential to generate electricity. Micro hydro energy is spread out and its potential (1.4 MW) can be utilized as an energy source to supply electricity in remote area. This province has huge geothermal potential (530 MW) that can be used to meet electricity demand as an alternative and/or additional power supply. The technical potential of lighting DSM application in terms of power and energy reduction was based on household survey and replacing the incandescent lamps with energy efficient CFL. The lighting load curve from household has been drawn and the study indicate that about 12 MW (14%) of peak load avoided and 56 GWh (14% of the current total electricity generation) can be achieved by lighting DSM. The C02 mitigation potential based on diesel substituted by the use of renewable energy and lighting DSM has been estimated. The current C02 emission of about 110 kT/year could be mitigated by the use of renewable energy resources. By adopting the lighting DSM proposed in the study, the C02 emission that can be mitigated is estimated at about 13.54 kT/year or 12.3% of current C02 emission. |
