Multi-Dimensional Assessment for Residential Lighting Demand Side Management: A Proposed Framework

Effective Demand Side Management (DSM) practices require adequate assessment in which several important factors are taken into consideration. Criteria to measure DSM potential and setting DSM targets are substantial to be well predefined. The aim of this paper is to propose assessment framework towards effective residential lighting demand side management planning. The assessment involves multi-dimensional factors comprising technical, economic, society preference, and environmental emission along with their mean of analysis. Technical dimension in terms of electricity demand is analyzed using Baseline Energy Use method whereas Life Cycle Cost analysis along with Cost-Benefit Assessment is used to calculate economic cost and other parameters during the project lifetime. Multi-criteria decision making using Analytic Hierarchy Process is performed to capture customer preference on selecting the preferable DSM loading scheme. In addition, environmental emission reduction potential is revealed using End-use Electricity Saving method.

Off-grid fully renewable energy with free capacity shortage for remote electrification

This paper presents feasibility study on optimal sizing and economic assessment of community electrification in the remote area using fully renewable energy system. The electricity is proposed to be delivered from a centralized renewable energy generating station. Study is focused to obtain the most appropriate power generation configuration with the lowest energy cost along with free systems capacity shortage over the study period. Possible renewable energy technologies analyzed in this study consists of micro hydro, photovoltaic-battery and wind turbine. From the analyses, system configuration that consists of all renewable resources is the most preferred one with least net present cost as well as least cost of energy during the project period.

Analisa Supply-demand pada Pembangkit Listrik Tenaga Mikro Hidro 32 KW di Desa Praingkareha, Kabupaten Sumba Timur

PLTMH Laputi merupakan pembangkit listrik tenaga air berskala mikro dengan kemampuan 32 KW. Analisa terkait dengan kebutuhan dan pasokan energi masyarakat desa Praingkareha pada tahun 2014, yaitu pada bulan Januari saat debit air melimpah dengan rata-rata debit air 106.66 L/detik dengan kapasitas 19.78 KW dan beban puncak 18.84 KW, kemudian bulan April saat debit air cukup dengan rata-rata debit air 96.61 L/detik dengan kapasitas 17.91 KW dan beban puncak 13.43 KW, dan pada bulan Agustus saat debit air kecil dengan rata-rata debit air 32.61 L/detik dengan kapasitas 6.05 KW dan beban puncak 15.35 KW. Hanya pada bulan Agustus energi yang dihasilkan tidak dapat memenuhi rata-rata kebutuhan energi masyarakat dengan nilai 61.35 KWh sedangkan rata-rata kebutuhan energi sebesar 299 KWh. Jika dilihat dari besarnya debit air maksimal sungai laputi dan besarnya kapasitas debit air turbin, maka turbin hanya bekerja sebesar 38.37% dari kemampuan yang seharusnya.

Perencanaan Sizing dan Analisa Biaya Energi Sistem PLTS di Komunitas Desa Muara Langon, Kabupaten Paser, Kalimantan Timur

Desa Muara Langon merupakan desa yang terletak di dekat perbatasan antara Kalimantan Timur – Kalimantan Selatan yang masih menggunakan Generator set (Genset) sebagai sumber listrik karena belum mendapatkan fasilitas aliran listrik dari PT PLN. Pemanfaatan sumber energi terbarukan sebagai sumber listrik bagi rumah tangga di daerah pedesaan merupakan solusi yang tepat untuk mengatasi ketiadaan sumber energi listrik. Penelitian Tugas Akhir ini menganalisa data radiasi sinar matahari di desa Muara Langon serta data total beban listrik dan kebutuhan energi listrik untuk perencanaan PLTS bagi rumah penduduk desa Muara Langon menggunakan software HOMER. Perencanaan sistem PLTS semi terpusat dapat memenuhi pertumbuhan beban mendekati 10 tahun sebesar 11,7% setiap tahunnya, serta sistem ini memiliki biaya energi sebesar USD 2,03/kWh. Sistem PLTS semi terpusat yang direncanakan masih memiliki biaya energi yang lebih tinggi dibandingkan sistem diesel existing yang memiliki biaya energi sebesar USD 1,02/kWh.
