Abstract

 This paper aims to conduct a techno-economic and grid analysis of a hybrid Diesel Power Plant and Solar Power Plant system on Simeulue Island. The research focuses on energy analysis and the impact of transitioning from diesel-based generation to solar-based (dedieselization) as a step toward sustainable energy development. Simeulue Island, home to approximately 96,000 residents, is entirely dependent on Diesel Power Plants (PLTD) due to its geographical isolation from Indonesia's main islands. However, the island
possesses considerable solar energy potential, offering a viable renewable energy source that can be utilized year-round. Through hybrid system simulations of PLTD and PLTS using PVsyst, Homer, this research will analyze the required energy generation to meet specific load demands at various times. The proposed photovoltaic (PV) system output capacity is 2.5 MW, utilizing 5,000 PV modules. The simulations indicate that this integration can produce approximately 4,349,203 kWh of solar energy, which contributes to a renewable energy penetration rate of 9.94% of the total load annually. From an economic perspective, the integration of solar
power into the existing diesel system leads to a notable reduction in the Levelized Cost of Energy (LCOE), which decreases from Rp 4,253/kWh to Rp 3,772/kWh.
