Sistem Tenaga Listrik (STL) Indonesia saat ini masih berkaca pada Negara Kontinental(daratan) dan tidak cocok jika terus diterapkan di Negara Kepulauan seperti Indonesia.Maka dengan membuat konsep Island Charging pada studi kasus Pulau Timor baik darisisi teknologi storage, supply chain dan keekonomian kiranya menjadi alternatif sertasolusi orisinil dalam memecahkan masalah energi seperti pemerataan elektrifikasi,terciptanya lingkungan bersih dan meningkatnya nilai tambah ekonomi serta benefituntuk daerah sekitarnya. Dimana metodologi yang digunakan mulai dari analisa teknistransportasi dan teknologi Mobile Energy Storage System (MESS), kemudian dilanjutkandengan analisa ekonomi menggunakan Livelized Cost of Storage (LCOS) pada MESSyang dominan dipengaruhi oleh moda transportasi. Hasil dari perhitungan tersebut akandibandingkan terhadap keekonomian Generator Setting (Genset) diesel di Pulau Wetarsehingga diperoleh kesimpulan bahwa konsep Island Charging ini dapat dikatakanfeasible apabila faktor eksternalitas ikut diperhitungkan dan adanya subsidi dariPemerintah jika menggunakan energi terbarukan

The current Indonesian Electric Power System (STL) still reflects on the Continental

Country (mainland) and is not suitable if it continues to be applied in an archipelago

country like Indonesia. So by making the concept of Island Charging in the case study of

Timor Island, both in terms of storage technology, supply chain, and economics, it is

likely to be an alternative and original solution in solving energy problems such as

equalization of electrification, creating a clean environment and increasing economic

added value and benefits to the surrounding area. The methodology used starts from

technical analysis of Mobile Energy Storage System (MESS) transportation and

technology, then continues with economic analysis using Levelized Cost of Storage

(LCOS) in MESS, which is dominantly influenced by the mode of transportation. The

results of these calculations will be compared to the economy of the Diesel Generator

Setting (Genset) on Wetar Island so that the conclusion is that the Island Charging concept

can be said to be feasible if externalities are taken into account, and there is a subsidy

from the Government when using renewable energy
