Abstract

East Nusa Tenggara Province has substantial solar energy potential, with an average annual solar irradiance of approximately 413 W/m² and 8 Peak Sun Hours (PSH) per day (NASA). This study proposes a comprehensive master plan for Solar Power Plant (SPP) development aligned with Indonesia's National Energy Policy (KEN), National Energy General Plan (RUEN), and PLN's Electricity Supply Business Plan (RUPTL). The methodology includes solar resource assessment, electricity demand analysis, technical evaluation of photovoltaic systems, techno-economic analysis, and the development of an implementation roadmap through 2048. The results indicate that phased SPP deployment effectively balances capital investment (CAPEX) and long-term revenue generation. Although the initial stage requires significant investment, increasing renewable electricity production during operation enhances project profitability and supports positive cash flow over its lifetime. The proposed master plan demonstrates favorable technical and economic feasibility while contributing to energy security, greenhouse gas emission reduction, and the transformation of East Nusa Tenggara into a strategic renewable energy hub in Eastern Indonesia.
