Abstract

Indonesia's commitment to energy transition and climate change mitigation has intensified focus on renewable energy development, particularly wind energy as a viable alternative to fossil fuels. This research assesses the feasibility of wind energy development in Poto Tano, West Sumbawa, West Nusa Tenggara, Indonesia, through an integrated analysis of energy production, environmental benefits, and financial viability. As part of Indonesia’s commitment to diversify its energy mix and reduce greenhouse gas emissions, wind energy offers a clean, renewable alternative to fossil fuels. The research examines the potential of wind energy by utilizing RETScreen Expert software to simulate energy production based on local wind data, estimate project costs, and evaluate financial performance using metrics such as Net Present Value (NPV) and Internal Rate of Return (IRR). The environmental assessment focuses on emission reductions achieved through the displacement of fossil fuel-based electricity generation. A comprehensive cost analysis, including capital expenditure (CapEx), operational expenditure (OpEx), and maintenance costs, is presented alongside a sensitivity analysis to explore the impact of key variables on project outcomes. The research further investigates financial risks using scenario-based simulations. Results show that the region possesses consistent and strong wind resources, especially during the dry season, supporting the viability of wind power generation. The findings demonstrate that the project can contribute to Indonesia’s renewable energy targets, offer socio-economic benefits to the local community, and align with national energy and environmental policy goals. This research provides a holistic reference for future wind energy initiatives in similar geographical contexts.

Abstract

Mataram City, the capital of West Nusa Tenggara Province, has strong potential for solar energy development due to its favorable geographic and climatic conditions. Indonesia’s commitment to reducing greenhouse gas (GHG) emissions by 41% by 2030, along with the province’s net zero emission goal by 2050, underscores the importance of renewable energy deployment. This study aims to evaluate the technical and economic feasibility of implementing solar panels as an alternative energy source in Mataram City and to assess their contribution to GHG emission reduction. The analysis uses RETScreen software with secondary data from NASA’s Surface Meteorology and Solar Energy (SSE) database. It covers resource assessment, cost analysis, and financial indicators including Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, and Levelized Cost of Electricity (LCOE). Mataram receives an average daily solar radiation of 5.4 kWh/m²/day, with consistent potential throughout the year. The financial analysis shows that the project is technically feasible and economically viable, supported by positive NPV and IRR values, and provides significant contributions to GHG reduction. Solar panel implementation in Mataram City is proven to be feasible in technical, financial, and environmental terms. The findings serve as a valuable reference for local governments in formulating sustainable and low-carbon energy strategies.
