Abstract

Permasalahan kelistrikan sering muncul seiring dengan kemajuan teknologi salah satunya adalah dalam hal kebutuhan energi listrik. Proyeksi kebutuhan energi listrik di Pulau Mendol 25 tahun mendatang mencapai 7 GWh dengan beban puncak 2.7 MW. Sistem kelistrikan Pulau Mendol saat ini menggunakan PLTD sebagai sumber energi. Terbatasnya pasokan energi, menyebabkan jam operasional listrik rata-rata mencapai 14 jam per hari. Untuk meningkatkan durasi pasokan listrik menjadi 24 jam terdapat dua pilihan yaitu pemasangan Pembangkit Listrik Tenaga Surya atau Interkoneksi Sistem Sumatera dengan Sistem Mendol melalui kabel bawah laut tegangan menengah 20 kV. Pemasangan kabel laut dan PLTS memerlukan analisa teknis dan ekonomi. Analisa teknis mencakup aliran daya dan performance ratio. Analisa ekonomi mencakup biaya investasi dan kelayakan suatu proyek. Memodelkan sistem sumatera dan sistem mendol ke aplikasi ETAP maka Sistem Mendol mengalami drop tegangan yang melewati standard yang ditetapkan. Performance ratio menunjukan sistem PLTS dapat merubah 66 % potensi energi matahari menjadi energi listrik. Dari nilai SF menunjukan 14,2% kebutuhan energi harian dipenuhi oleh sistem PLTS. Analisa ekonomi pemasangan kabel laut Sumatera – Mendol tidak layak dilakukan karena nilai NPV bernilai negatif dan nilai PI bernilai kurang dari satu sedangkan pemasangan sistem PLTS layak untuk dilakukan nilai NPV bernilai positif, nilai PI bernilai lebih dari satu, payback period selama 17 tahun 7 hari.

Electrical problems often arise along with technological advances, one of which is in terms of electrical energy needs. The projection of electrical energy needs on Mendol Island in the next 25 years reaches 7 GWh with a peak load of 2.7 MW. The current Mendol Island electrical system uses PLTD as an energy source. Limited energy supply causes the average electricity operating hours to reach 14 hours per day. To increase the duration of the electricity supply to 24 hours, there are two options, namely the installation of a Solar Power Plant or the Interconnection of the Sumatra System with the Mendol System via a 20 kV medium voltage submarine cable. The installation of submarine cables and PLTS requires technical and economic analysis. Technical analysis includes power flow and performance ratio. Economic analysis includes investment costs and the feasibility of a project. Modeling the Sumatra system and the Mendol system to the ETAP application, the Mendol System experiences a voltage drop that exceeds the set standard. The performance ratio shows that the PLTS system can convert 66% of the potential solar energy into electrical energy. The SF value shows that 14.2% of daily energy needs are met by the PLTS system. The economic analysis of the installation of the Sumatra-Mendol submarine cable is not feasible because the NPV value is negative and the PI value is less than one, while the installation of the PLTS system is feasible because the NPV value is positive, the PI value is more than one, the payback period is 17 years and 7 days.
