Abstract

Indonesia menghadapi tantangan besar dalam memenuhi kebutuhan listrik yang terus meningkat sekaligus mengurangi dampak lingkungan yang terkait dengan pembangkit berbasis bahan bakar fosil. Sistem hibrida energi terbarukan, khususnya konfigurasi Fotovoltaik–Angin–Baterai, menawarkan solusi berkelanjutan untuk mengatasi tantangan tersebut. Penelitian ini mengevaluasi keandalan teknis dan kelayakan ekonomi penerapan sistem energi terbarukan hibrida di PLN Nusantara Power UP Brantas, Tulungagung, dengan penekanan pada pengelolaan beban secara strategis untuk meningkatkan kelayakan ekonomi dan manfaat lingkungan. Analisis Biaya Siklus Hidup (Life Cycle Cost Analysis/LCCA) secara komprehensif dan simulasi menggunakan perangkat lunak HOMER dilakukan untuk mengevaluasi parameter ekonomi seperti total Biaya Siklus Hidup (Life Cycle Cost/LCC) dan Biaya Energi Listrik Teraras (Levelized Cost of Electricity/LCOE). Total LCC yang diperoleh adalah sebesar Rp1.611 juta selama masa operasi 20 tahun, dengan nilai LCOE hasil perhitungan manual sebesar Rp32.939,33/kWh dan hasil simulasi HOMER sebesar Rp39.978,62/kWh. Analisis sensitivitas menunjukkan perbaikan ekonomi yang signifikan melalui optimalisasi beban, mengurangi kelebihan energi dari 49% menjadi sekitar 8%, serta menurunkan nilai LCOE menjadi Rp18.299,63/kWh dengan peningkatan beban sebesar 80%. Variasi tingkat diskonto (3–7%) mempengaruhi nilai LCOE dari Rp36.103,33/kWh menjadi Rp30.273,98/kWh, yang menunjukkan bahwa LCOE menurun pada tingkat diskonto yang lebih tinggi. Sensitivitas terhadap variasi biaya operasi dan pemeliharaan (±20%) mengubah nilai LCOE sekitar ±6%, yaitu dari Rp31.047,01/kWh hingga Rp34.831,66/kWh.

Indonesia faces significant challenges in meeting increasing electricity demand while simultaneously reducing environmental impacts associated with fossil fuel-based generation. Renewable hybrid systems, specifically Photovoltaic–Wind–Battery configurations, offer sustainable solutions to address these challenges. This research assesses the technical reliability and economic feasibility of implementing hybrid renewable energy systems at PLN Nusantara Power UP Brantas, Tulungagung, emphasizing strategic load management to enhance economic viability and environmental benefits. A comprehensive Life Cycle Cost Analysis (LCCA) and HOMER simulations were conducted to evaluate economic parameters such as total Life Cycle Cost (LCC) and Levelized Cost of Electricity (LCOE). The total LCC calculated was Rp1.611 million over a 20-year lifespan, with manual LCOE at Rp32.939,33/kWh and HOMER simulation at Rp39.978,62/kWh. Sensitivity analyses demonstrated substantial economic improvements through load optimization, reducing surplus energy from 49% to approximately 8%, lowering the LCOE to Rp18.299,63/kWh at an 80% load increase. Discount rate variation (3–7%) impacted LCOE from Rp36.103,33/kWh to Rp30.273,98/kWh, indicating decreased LCOE at higher discount rates. Sensitivity to operational and maintenance cost variations (±20%) changed LCOE by about ±6%, from Rp31.047,01/kWh to Rp34.831,66/kWh.
