This feasibility study aims to assess the potential of implementing a micro hydro system in Lalumpe Village, located in North Sulawesi, Indonesia. The study focuses on evaluating the technical and economic aspects of the proposed micro hydro project. Data collection was carried out through field surveys, interviews with local stakeholders, and analysis of available hydrological and topographical data. The technical assessment involved conducting a resource assessment to determine the water availability and potential for harnessing hydroelectric power in the area. The study also examined the village’s energy demand and determined the suitable capacity of the micro hydro system required to meet the community’s needs. Economic analysis included estimating the initial investment costs, operation and maintenance expenses, and potential revenue generation from the sale of excess electricity to the local grid. Financial viability indicators such as payback period and net present value were calculated to assess the economic feasibility of the project.

The ambitious planning of renewable energy utilization in Indonesia to achieve 23% in the country’s energy mix by 2025 pushes the development of model community using a Photovoltaic (PV) stand-alone system. The issue about island electricity access is happening in Bunaken as one of the famous tourist spots in Indonesia. Island communities are facing limited access toward the availability of electrical energy day and night time. This article aims to develop a model for solar energy utilization in Bunaken island communities for tourism spots. The design and cost-benefit analysis have been done for Bunaken community for lighting and handphone charging. The result indicated that the utilization of PV stand-alone system in Bunaken can be introduced by solar luggage package for the communities who willing to support their small-medium enterprise.

The purpose of this study is to design a Photovoltaics (PV) stand-alone system for a residential load in Bunaken Island using HOMER (Hybrid Optimization of Multiple Energy Resources). Bunaken Island, the case study location, is a popular tourist spot in North Sulawesi, Indonesia. This island is facing the issue of limited access to electrical energy from the grid. The design and techno-economic analysis in Bunaken island leveraged HOMER software. This software was developed by National Renewable Energy Laboratory (NREL). Furthermore, the results suggested that the techno-economical PV stand-alone system in Bunaken Island could be developed as alternative energy to support electricity as energy security issued for Indonesia.

This paper describes a preliminary study of the empowering remote island communities with renewable energy. This research is a case study for Talaud island which is located in the border island between Indonesia and Philipines. It is located in Kiama village Talaud Island regency of North Sulawesi province of Indonesia. Method of implementation of this program consists of several stages, namely: (1) Implementation of small-scale solar home system and a wind turbine; (2) Through technology transfer in the capacity building activities to the selected community, in order to provide the skill and knowledge to island community in Kiama Village, Talaud Islands of Indonesia. It is expected that technology implementation will be maintained in the future and sustainable. The life cycle cost analysis is done by comparing two system of pilot projects, namely solar home system and solar home system with a wind turbine. The cost of generating electrical energy with renewable energy is relatively high then it is necessary to provide strategies for the development of power infrastructure for the sake of the energy security of island communities in Indonesia. Further both monitoring and evaluation of the renewable energy system implementation should be conducted for the detail report and analysis.
