Abstract
Penelitian ini bertujuan untuk menganalisis kelayakan teknis dan ekonomi pembangunan Pembangkit Listrik Tenaga Surya Terkonsentrasi (Concentrated Solar Power - CSP) tipe Parabolic Trough Collector (PTC) pada area Greenfiled 10 ha berbasis Organic Rankine Cycle (ORC). Studi kasus difokolkan pada pemenuhan beban listrik di wilayah kelistrikan terisolasi (isolated grid) Ropa dan Talaud di Kawasan Wallacea, guna memproyeksikan potensi penggantian pembangkit berbasis bahan bakar fosil secara mandiri (standalone greenfield). Metode penelitian menggunakan pendekatan teoretis/komputasi melalui simulasi numerik berjenjang tiga tahap (Sandwich Model) yang mengintegrasikan perangkat lunak System Advisor Model (SAM) dan DWSIM, serta divalidasi secara analitis. Pada tahap awal, SAM digunakan untuk memodelkan lapangan surya dan menghitung input energi termal tahunan berdasarkan data radiasi matahari langsung (Direct Normal Irradiance - DNI). Selanjutnya, data energi termal diolah di dalam DWSIM untuk mensimulasikan karakteristik termodinamika siklus ORC berfluida Isopentane, menentukan dimensi fisik alat penukar panas, serta menghitung nilai efisiensi neto sistem. Parameter dimensi tersebut kemudian diintegrasikan dengan Persamaan Korelasi Biaya (Metode Turton) untuk mendapatkan estimasi nilai investasi (Capital Expenditure - CAPEX) blok daya yang akurat sebelum dikembalikan ke SAM untuk analisis finansial makro harian selama 8.760 jam. Hasil pemodelan dianalisis untuk menentukan efisiensi termal total pembangkit dan kelayakan ekonomi melalui indikator Levelized Cost of Energy (LCOE), Net Present Value (NPV), dan Internal Rate of Return (IRR). Pembangunan pembangkit CSP-ORC di lokasi studi diproyeksikan layak dengan memanfaatkan karakteristik DNI yang tinggi di Wallacea, serta mampu menawarkan kemandirian energi dan mereduksi emisi gas rumah kaca secara signifikan pada sistem ketenagalistrikan local.

This research aims to analyze the technical and economic feasibility of establishing an Organic Rankine Cycle (ORC)-based Concentrated Solar Power (CSP) plant utilizing Parabolic Trough Collectors (PTC) on a 10-hectare greenfield area. The case study focuses on meeting the electrical demand of isolated grids in Ropa and Talaud within the Wallacea region, projecting the potential of independent greenfield standalone power generation. The research employs a theoretical/computational method via a three-stage numerical simulation known as the Sandwich Model, which integrates System Advisor Model (SAM) and DWSIM software, and is validated through analytical methods. In the initial stage, SAM is utilized to model the solar field and calculate the annual thermal energy input based on Direct Normal Irradiance (DNI) data. Subsequently, the thermal energy data is processed within DWSIM to simulate the ORC thermodynamic characteristics using Isopentane as the working fluid, determine the physical dimensions of heat exchangers, and calculate the net system efficiency. These dimensional parameters are then integrated with the Cost Correlation Equation (Turton Method) to obtain accurate Capital Expenditure (CAPEX) estimates for the power block before being fed back into SAM for macro-financial analysis over a dynamic 8,760-hour simulation. The modeling results are evaluated to determine the total thermal efficiency of the plant and its economic viability through key financial indicators, including Levelized Cost of Energy (LCOE), Net Present Value (NPV), and Internal Rate of Return (IRR). The implementation of CSP-ORC plant at the study sites is projected to be viable by leveraging the high DNI characteristics of the Wallacea region, offering energy independence and significantly reducing greenhouse gas emissions within the local power system.
