Abstract
Pulau Bunaken, Manado – Sulawesi Utara, merupakan satu pulau yang bergantung pada sistim hibrida tenaga diesel-surya untuk memenuhi kebutuhan listriknya. PLTS Pulau Bunaken menggunakan penyimpanan energi berbasis baterai yaitu baterai VRLA jenis OPzS yang memiliki keterbatasan dalam hal efisiensi, masa pakai (siklus) dan biaya operasional. Baterai Lithium Iron Phosphate (LiFePO4) menawarkan keunggulan dalam hal efisiensi pengisian, masa pakai yang lebih lama dan lebih ramah lingkungan (Suratsawadee Anuphapparadorn et al, 2014). Penelitian ini bertujuan untuk menganalisis dampak teknis, ekonomi dan lingkungan dari penggantian baterai VRLA OPzS dengan baterai LiFePO4 di Pulau Bunaken. Metode yang digunakan adalah pendekatan tekno-ekonomi dengan simulasi berbasis perangkat lunak Homer Pro untuk mengevaluasi efisiensi sistem, perhitungan Levelized Cost of Energy (LCOE), Total Cost of Ownership (TCO), Return on Investment (ROI), Net Present Value (NPV) serta analisis dampak lingkungan berdasarkan pengurangan emisi CO2 sebagai dampak dari penghematan penggunaan Bahan Bakar Minyak (BBM). Berdasarkan optimasi dengan skenario dedieselisasi, optimasi PV dan menggunakan baterai LiFePO4 didapatkan hasil LCOE turun 21,6%, konsumsi BBM turun 22%, renewable fraction naik menjadi 24,9% dan emisi CO2 turun 21%.

Bunaken Island, Indonesia, is an island that relies on a diesel-solar hybrid system to meet its electricity needs. The Solar Power Plant (Pembangkit Listrik Tenaga Surya, PLTS) of Bunaken Island uses battery-based energy storage, namely OPzS batteries as a sub type of VRLA batteries which have limitations in terms of efficiency, life cycle and operational costs. Lithium Iron Phosphate (LiFePO4) batteries offer advantages in terms of charging efficiency, longer service life and more environmentally friendly. This study aims to analyze the technical, economic and environmental impacts of replacing VRLA OPzS batteries with LiFePO4 batteries in Bunaken Island. The method used is a techno-economic approach with Homer Pro software-based simulations to evaluate system efficiency, calculate Levelized Cost of Energy (LCOE), Total Cost of Ownership (TCO), Return on Investment (ROI), Net Present Value (NPV) and environmental impact analysis based on CO2 emission as an impact of decreasing use of diesel fuel. Results indicate that LiFePO4 significantly improves system economic and performance. LCOE decreases by 21.6%, fuel consumption decreases by 22%, renewable fraction increases to 24,9% and the emission of CO2 decreases by 21%.
