Abstract

Penelitian ini bertujuan untuk menganalisis penerapan Pembangkit Listrik Tenaga Surya (PLTS) Atap di sektor rumah tangga, industri, dan sosial di Jawa Tengah, serta mengevaluasi dampak perubahan kebijakan terhadap keuntungan ekonomi dan payback period PLTS Atap. Metode yang digunakan adalah pendekatan mixed methods dengan simulasi PVSyst untuk analisis teknis dan perhitungan Net Present Value (NPV), Internal Rate of Return (IRR), serta payback period untuk menilai kelayakan ekonomi. Data dikumpulkan melalui survei, wawancara dengan pakar, dan analisis data historis pelanggan. Hasil penelitian menunjukkan bahwa kebijakan yang menghapus batas kapasitas daya tersambung memberikan keuntungan bagi sektor industri, tetapi sektor rumah tangga dan sosial terpengaruh negatif dengan penghapusan insentif ekspor. Secara teknis, PLTS Atap menghasilkan energi yang cukup efisien, namun penghapusan ekspor energi meningkatkan biaya dan memperpanjang payback period, terutama di sektor rumah tangga dan sosial. Implikasi kebijakan ini menekankan pentingnya penyederhanaan prosedur administratif untuk meningkatkan minat pelanggan. Dampak terhadap pendapatan PLN diperkirakan sekitar 0,18%, yang relatif kecil, namun dampaknya tetap signifikan dalam jangka panjang. Penelitian ini memberikan rekomendasi untuk pemerintah dan PLN dalam mendukung pengembangan PLTS Atap yang berkelanjutan.

Abstract

Global climate change and rising greenhouse gas (GHG) emissions demand an accelerated transition from fossil fuels to sustainable energy systems. Floating solar power plants (FSPs) are one strategy for integrating renewable and conventional energy sources by utilizing water bodies without causing land-use conflicts. However, this implementation faces challenges related to fluctuations in solar irradiance, aquatic environmental characteristics, and economic uncertainty in investment, particularly for self-consumption schemes at existing power plants such as the Tambak Lorok Combined Cycle Power Plant (CCPP) in Semarang City. This study aims to analyze the technical feasibility, contribution to CO₂ emission reduction, and economic viability of developing a floating PV plant at Tambak Lorok. The research methodology employs a quantitative-analytical approach based on secondary data and system simulation. The study utilizes data on solar irradiance, meteorology, technical specifications of modules and inverters, electricity consumption data from the gas-fired power plant, and project economic parameters. The analysis was conducted through technical, environmental, economic, and integrative approaches. The results show that a 1.166 MWp floating solar power plant system is capable of generating approximately 1,810 MWh of electricity per year, with a performance ratio (PR) of around 85%, indicating efficient system performance. From an environmental perspective, this system has the potential to reduce carbon emissions by approximately 1,085 tons of CO₂ per year, or about 32,558 tons of CO₂ over the project’s 30-year lifespan.Economically, the project is deemed viable, with a net present value (NPV) of Rp5.45 billion, an internal rate of return (IRR) of 12.8%, and a payback period of 11.48 years. These results indicate that the development of a floating solar power plant in Tambak Lorok is technically feasible, provides significant environmental benefits, and is economically profitable, thereby having the potential to serve as a model for the energy transition of fossil-fuel-based power plants in Indonesia.
